If you want, I can take the csproj list you pasted and produce a concrete “catalog expansion” that enumerates **every** production csproj, assigns it a model, and lists the exact missing suites (based on the presence/absence of sibling `*.Tests` projects and their current naming). That output can be committed as `TEST_CATALOG.generated.yml` and used as a tracking board.
|

|

|

----------------------------------------------- Part #2 -----------------------------------------------
|
||||
I’m sharing this because the SBOM and attestation standards you’re tracking are **actively evolving into more auditable, cryptographically strong building blocks for supply‑chain CI/CD workflows** — and both CycloneDX and Sigstore/in‑toto are key to that future.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
**CycloneDX 1.6 & SPDX 3.0.1:**
|
||||
• CycloneDX v1.6 was released with major enhancements around cryptographic transparency — including Cryptographic Bill of Materials (CBOM) and native attestation support (CDXA), making it easier to attach and verify evidence about components and their properties. ([CycloneDX][1])
|
||||
• CycloneDX is designed to serve modern SBOM needs and can represent a wide range of supply‑chain artifacts and relationships directly in the BOM. ([FOSSA][2])
|
||||
• SPDX 3.0.1 is the latest revision of the SPDX standard, continuing its role as a highly expressive SBOM format with broad metadata support and international recognition. ([Wikipedia][3])
|
||||
• Together, these formats give you strong foundations for **“golden” SBOMs** — standardized, richly described BOM artifacts that tools and auditors can easily consume.
|
||||
|
||||
**Attestations & DSSE:**
|
||||
• Modern attestation workflows (e.g., via **in‑toto** and **Sigstore/cosign**) revolve around **DSSE (Dead Simple Signing Envelope)** for signing arbitrary predicate data like SBOMs or build metadata. ([Sigstore][4])
|
||||
• Tools like cosign let you **sign SBOMs as attestations** (e.g., SBOM is the predicate about an OCI image subject) and then **verify those attestations** in CI or downstream tooling. ([Trivy][5])
|
||||
• DSSE provides a portable envelope format so that your signed evidence (attestations) is replayable and verifiable in CI builds, compliance scans, or deployment gates. ([JFrog][6])
|
||||
|
||||
**Why it matters for CI/CD:**
|
||||
• Standardizing on CycloneDX 1.6 and SPDX 3.0.1 formats ensures your SBOMs are both **rich and interoperable**.
|
||||
• Embedding **DSSE‑signed attestations** (in‑toto/Sigstore) into your pipeline gives you **verifiable, replayable evidence** that artifacts were produced and scanned according to policy.
|
||||
• This aligns with emerging supply‑chain security practices where artifacts are not just built but **cryptographically attested before release** — enabling stronger traceability, non‑repudiation, and audit readiness.
|
||||
|
||||
In short: focus first on adopting **CycloneDX 1.6 + SPDX 3.0.1** as your canonical SBOM formats, and then **integrate DSSE‑based attestations (in‑toto/Sigstore)** to ensure those SBOMs and related CI artifacts are signed and verifiable across environments.

Here’s a simple, practical way to make vulnerability “reachability” auditable and offline‑verifiable in Stella Ops without adding a lot of UI or runtime cost.
|
||||
|
||||
|
||||
|
||||
# What this is (plain English)
|
||||
|
||||
* **Call‑stack subgraph:** when we say a vuln is “reachable,” we really mean *some* functions in your code can eventually call the risky function. That tiny slice of the big call graph is the **subgraph**.
|
||||
* **Proof of exposure (PoE):** a compact bundle (think: a few kilobytes) that cryptographically proves *which* functions and edges make the vuln reachable in a specific build.
|
||||
* **Offline‑verifiable:** auditors can check the proof later, in an air‑gapped setting, using only hashes and your reproducible build IDs.
|
||||
|
||||
# The minimal data model
|
||||
|
||||
* **BuildID:** deterministic identifier (e.g., ELF Build‑ID or source‑of‑truth content hash).
|
||||
* **Nodes:** function identifiers `(module, symbol, debug‑addr, source:line?)`.
|
||||
* **Edges:** caller → callee (with optional guard predicates like feature flags).
|
||||
* **Entry set:** the function(s)/handlers reachable from runtime entrypoints (HTTP handlers, cron, CLI).
|
||||
* **Sink set:** vulnerable API(s)/function(s) tied to a CVE.
|
||||
* **Reachability proof:** `{BuildID, nodes[N], edges[E], entryRefs, sinkRefs, policyContext, toolVersions}` + DSSE signature.
|
||||
|
||||
# How it fits the Stella Ops ledger
|
||||
|
||||
* Store each **resolved call‑stack** as a **subgraph object** keyed by `(BuildID, vulnID, package@version)`.
|
||||
* Link it to:
|
||||
|
||||
* SBOM component node (CycloneDX/SPDX ref).
|
||||
* VEX claim (affected/not‑affected/under‑investigation).
|
||||
* Scan recipe (so anyone can replay the result).
|
||||
* Emit one **PoE artifact** per “(vuln, component) with reachability=true”.
|
||||
|
||||
# Why this helps
|
||||
|
||||
* **Binary precision + explainability:** even if you only have a container image, the PoE explains *why* it’s reachable.
|
||||
* **Auditor‑friendly:** tiny artifact, DSSE‑signed, replayable with a known scanner build.
|
||||
* **Noise control:** store reachability as first‑class evidence; triage focuses on subgraphs, not global graphs.
|
||||
|
||||
# Implementation guide (short and concrete)
|
||||
|
||||
**1) Extraction (per build)**
|
||||
|
||||
* Prefer source‑level graphs when available; otherwise:
|
||||
|
||||
* ELF/PE/Mach‑O symbol harvest + debug info (DWARF/PDB) if present.
|
||||
* Lightweight static call‑edge inference (import tables, PLT/GOT, relocation targets).
|
||||
* Optional dynamic trace sampling (eBPF hooks) to confirm hot edges.
|
||||
|
||||
**2) Resolution pipeline**
|
||||
|
||||
* Normalize function IDs: `ModuleHash:Symbol@Addr[:File:Line]`.
|
||||
* Compute **entry set** (framework adapters know HTTP/GRPC/CLI entrypoints).
|
||||
* Compute **sink set** via rulepack mapping CVEs → {module:function(s)}.
|
||||
* Run bounded graph search with **policy guards** (feature flags, platform, build tags).
|
||||
* Persist the **subgraph** + metadata.
|
||||
|
||||
**3) PoE artifact (OCI‑attached attestation)**
|
||||
|
||||
* Canonical JSON (stable sort, normalized IDs).
|
||||
* Include: BuildID, tool versions, policy digest, SBOM refs, VEX claim link, subgraph nodes/edges, minimal repro steps.
|
||||
* Sign via DSSE; attach as OCI ref to the image digest.
|
||||
|
||||
**4) Offline verification (auditor)**
|
||||
|
||||
* Inputs: PoE, image digest, SBOM slice.
|
||||
* Steps: verify DSSE → check BuildID ↔ image digest → confirm nodes/edges hashes → re‑evaluate policy (optional) → show minimal path(s) entry→sink.
|
||||
|
||||
# UI: keep it small
|
||||
|
||||
* **Evidence tab → “Proof of exposure”** pill on any reachable vuln row.
|
||||
* Click opens a tiny **path viewer** (entry→…→sink) with:
|
||||
|
||||
* path count, shortest path, guarded edges (badges for feature flags).
|
||||
* “Copy PoE JSON” and “Verify offline” instructions.
|
||||
* No separate heavy UI needed; reuse the existing vulnerability details drawer.
|
||||
|
||||
# C# shape (sketch)
|
||||
|
||||
```csharp
|
||||
record FunctionId(string ModuleHash, string Symbol, ulong Addr, string? File, int? Line);
|
||||
record Edge(FunctionId Caller, FunctionId Callee, string[] Guards);
|
||||
record Subgraph(string BuildId, string ComponentRef, string VulnId,
|
||||
IReadOnlyList<FunctionId> Nodes, IReadOnlyList<Edge> Edges,
|
||||
string[] EntryRefs, string[] SinkRefs,
|
||||
string PolicyDigest, string ToolchainDigest);
|
||||
|
||||
interface IReachabilityResolver {
|
||||
Subgraph Resolve(string buildId, string componentRef, string vulnId, ResolverOptions opts);
|
||||
}
|
||||
|
||||
interface IProofEmitter {
|
||||
byte[] EmitPoE(Subgraph g, PoeMeta meta); // canonical JSON bytes
|
||||
}
|
||||
```
|
||||
|
||||
# Policy hooks you’ll want from day one
|
||||
|
||||
* `fail_if_unknown_edges > N` in prod.
|
||||
* `require_guard_evidence` for claims like “feature off”.
|
||||
* `max_paths`/`max_depth` to keep proofs compact.
|
||||
* `source-first-but-fallback-binary` selection.
|
||||
|
||||
# Rollout plan (2 sprints)
|
||||
|
||||
* **Sprint A (MVP):** static graph, per‑component sinks, shortest path only, PoE JSON + DSSE sign, attach to image, verify‑cli.
|
||||
* **Sprint B (Hardening):** guard predicates, multiple paths with cap, eBPF confirmation toggle, UI path viewer, policy gates wired to release checks.

I’m sharing this because the way *signed attestations* and *SBOM formats* are evolving is rapidly reshaping how supply‑chain security tooling like Trivy, in‑toto, CycloneDX, SPDX, and Cosign interoperate — and there’s a clear gap right now you can exploit strategically.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
**Attested‑first scanning and in‑toto/DSSE as truth anchors**
|
||||
• The core idea is to *treat attestations themselves as the primary artifact to verify*. An in‑toto/DSSE attestation isn’t just an SBOM — it’s a *signed cryptographic statement* about the SBOM or other metadata (build provenance, test results, etc.), enabling trust decisions in CI/CD and runtime. ([SLSA][1])
|
||||
• Tools like *Cosign* generate and verify these in‑toto attestations — you can use `cosign verify‑attestation` to extract the SBOM payload from a DSSE envelope before scanning. ([Trivy][2])
|
||||
• CycloneDX’s attestation work (often referenced as **CDXA**) formalizes how attestations describe compliance claims and can *automate audit workflows*, making them machine‑readable and actionable. ([CycloneDX][3])
|
||||
|
||||
**Trivy’s dual‑format SBOM and attestation support — and the current parity gap**
|
||||
• *Trivy* already ingests *CycloneDX‑type SBOM attestations* (where the SBOM is wrapped in an in‑toto DSSE envelope). It uses Cosign‑produced attestations as inputs for its SBOM scanning pipeline. ([Trivy][4])
|
||||
• Trivy also scans traditional CycloneDX and SPDX SBOMs directly (and supports SPDX‑JSON). ([Trivy][5])
|
||||
• However, *formal parsing of SPDX in‑toto attestations is still tracked and not fully implemented* (evidence from feature discussions and issues). This means there’s a *window where CycloneDX attestation support is ahead of SPDX attestation support*, and tools that handle both smoothly will win in enterprise pipelines. ([GitHub][6])
|
||||
• That gap — *full SPDX attestation ingestion and verification* — remains a differentiation opportunity: build tooling or workflows that standardize acceptance and verification of both attested CycloneDX and attested SPDX SBOMs with strong replayable verdicts.
|
||||
|
||||
**Why this matters right now**
|
||||
Signed attestations (via DSSE/in‑toto and Cosign) turn an SBOM from a passive document into a *verified supply‑chain claim* that can gate deployments and signal compliance postures. Tools like Trivy that ingest these attestations are at the forefront of that shift, but not all formats are on equal footing yet — giving you space to innovate workflows or tooling that closes the parity window. ([Harness][7])
|
||||
|
||||
If you want follow‑up examples of commands or how to build CI/CD gates around these attestation flows, just let me know.

- **Cryptographic Binding:** Each verdict cryptographically signed, tamper-evident
|
||||
- **Granular Attestations:** One attestation per finding (not batch)
|
||||
- **Transparency Option:** Rekor anchoring for public auditability
|
||||
- **Offline Verification:** Signature verification without network
|

**Key Differentiators:**
|
||||
- **Complete Context:** Single bundle contains all evaluation inputs
|
||||
- **Deterministic Replay:** Bit-for-bit reproducible verdicts
|
||||
- **Queryable Offline:** Inspect without external APIs
|
||||
- **Air-Gap Transfer:** Sign once, verify anywhere

|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||
|
||||
- [ ] Verdict predicate builder (canonical JSON, determinism)
|
||||
- [ ] Evidence pack assembler (manifest generation, determinism hash)
|
||||
- [ ] Replay service (deserialization, comparison logic)
|
||||
- [ ] Schema validation (JSON schema compliance)
|
||||
|
||||
### Integration Tests
|
||||
|
||||
- [ ] End-to-end: Policy Run → Verdict Attestation → Storage → Retrieval → Verification
|
||||
- [ ] End-to-end: Pack Assembly → Storage → Download → Replay → Determinism Validation
|
||||
- [ ] Cross-environment: Create pack on env A, replay on env B (air-gap scenario)
|
||||
- [ ] Signature verification (offline, no network)
|
||||
|
||||
### Performance Tests
|
||||
|
||||
- [ ] Verdict attestation throughput (1M verdicts/hour target)
|
||||
- [ ] Pack assembly time (< 2min for 10K findings)
|
||||
- [ ] Replay time (< 60s for 10K verdicts)
|
||||
- [ ] Storage scaling (100K packs, query performance)
|
||||
|
||||

|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Cryptographic Guarantees
|
||||
|
||||
- **Verdict Attestations:** DSSE-signed, tamper-evident, optional Rekor transparency
|
||||
- **Evidence Packs:** Manifest signature, per-file digests, determinism hash
|
||||
- **Key Management:** KMS, CryptoPro (GOST), offline signing ceremonies
|
||||
- **Verification:** Offline-capable, no network required
|
||||
|
||||
### Access Control
|
||||
|
||||
- **RBAC Scopes:**
|
||||
- `policy:verdict:read` — View verdict attestations
|
||||
- `policy:pack:create` — Create evidence packs
|
||||
- `policy:pack:read` — Download evidence packs
|
||||
- `policy:replay` — Replay policy evaluations
|
||||
|
||||
- **Tenant Isolation:** All artifacts scoped by `tenantId`, cross-tenant queries blocked
|
||||
|
||||
### Audit Trail
|
||||
|
||||
- All verdict retrievals logged with actor, timestamp, tenant
|
||||
- Pack creation/download/replay logged for compliance
|
||||
- Signature verification failures alerted
|
||||
|
||||
---
|
||||
|
||||
## Determinism Validation
|
||||
|
||||
### Verdict Determinism
|
||||
|
||||
**Inputs:**
|
||||
- Policy definition (P-7 v4)
|
||||
- SBOM (sbom:S-42)
|
||||
- Advisory snapshot (at cursor timestamp)
|
||||
- VEX snapshot (at cursor timestamp)
|
||||
- Environment context
|
||||
|
||||
**Output:** Verdict with `determinismHash` = SHA256(sorted evidence digests)
|
||||
|
||||
**Validation:** Re-evaluate with identical inputs → same `determinismHash`
|
||||
|
||||
### Pack Replay Determinism
|
||||
|
||||
**Inputs:** Evidence pack manifest (all artifacts bundled)
|
||||
|
||||
**Output:** Replay verdicts
|
||||
|
||||
**Validation:** Compare replay verdicts to original verdicts:
|
||||
- Count match: 234 original, 234 replay ✓
|
||||
- Status match: All verdicts have identical status ✓
|
||||
- Hash match: All `determinismHash` values identical ✓
|
||||

Here’s a compact blueprint for two high‑leverage Stella Ops capabilities that cut false positives and make audits portable across jurisdictions.
|
||||
|
||||
# 1) Patch‑aware backport detector (no humans in loop)
|
||||
|
||||
**Goal:** Stop flagging CVEs when a distro backported the fix but kept the old version string.
|
||||
|
||||
**How it works—in plain terms**
|
||||
|
||||
* **Compile equivalence maps per distro:**
|
||||
|
||||
* BuildID → symbol ranges → hunk hashes for core libraries/kernels.
|
||||
* For each upstream CVE fix, store the minimal “hunk signature” (function, file path, before/after diff hash).
|
||||
* **Auto‑diff at scan time:**
|
||||
|
||||
* From a container/VM, collect ELF BuildIDs and symbol tables (or BTF for kernels).
|
||||
* Match against the equivalence map; if patched hunks are present, mark the artifact “fixed‑by‑backport”.
|
||||
* **Emit proof‑carrying VEX:**
|
||||
|
||||
* Generate a signed VEX entry with `status:not_affected`, `justification: patched-backport`, and attach a **proof blob**: (artifact BuildIDs, matched hunk IDs, upstream commit refs, deterministic diff snippet).
|
||||
* **Release‑gate policy:**
|
||||
|
||||
* Gate only passes if (a) VEX is signed by an approved issuer, (b) proof blob verifies against our equivalence map, (c) CVE scoring policy is met.
|
||||
|
||||
**Minimal data model**
|
||||
|
||||
* `EquivalenceMap{ distro, package, version_like, build_id, [HunkSig{file,func, pre_hash, post_hash, upstream_commit}] }`
|
||||
* `ProofBlob{ artifact_build_ids, matched_hunks[], verifier_log }`
|
||||
* `VEX{ subject=digest/ref, cve, status, justification, issued_by, dsse_sig, proof_ref }`
|
||||
|
||||
**Pipeline sketch (where to run what)**
|
||||
|
||||
* **Feedser**: pulls upstream CVE patches → extracts HunkSig.
|
||||
* **Sbomer**: captures BuildIDs for binaries in SBOM.
|
||||
* **Vexer**: matches hunks → emits VEX + proof.
|
||||
* **Authority/Attestor**: DSSE‑signs; stores in OCI referrers.
|
||||
* **Policy Engine**: enforces “accept only if proof verifies”.
|
||||
|
||||
**Testing targets (fast ROI)**
|
||||
|
||||
* glibc, openssl, zlib, curl, libxml2, Linux kernel LTS (common backports).
|
||||
|
||||
**Why it’s a moat**
|
||||
|
||||
* Precision jump without humans; reproducible proof beats “trust me” advisories.
|
||||

# 2) Regional crypto & offline audit packs
|
||||
|
||||
**Goal:** Hand an auditor a single, sealed bundle that **replays identically** anywhere—while satisfying local crypto regimes.
|
||||
|
||||
**What’s inside the bundle**
|
||||
|
||||
* **Evidence:** SBOM (CycloneDX 1.6/SPDX 3.0.1), VEX set, reachability subgraph (source+post‑build), policy ledger with decisions.
|
||||
* **Attestations:** DSSE/in‑toto for each step.
|
||||
* **Replay manifest:** feed snapshots + rule versions + hashing seeds so a third party can re‑execute and get the same verdicts.
|
||||
|
||||
**Dual‑stack signing profiles**
|
||||
|
||||
* eIDAS / ETSI (EU), FIPS (US), GOST/SM (RU/CN regional), plus optional PQC (Dilithium/Falcon) profile.
|
||||
* Same content; different signature suites → auditor picks the locally valid one.
|
||||
|
||||
**Operating modes**
|
||||
|
||||
* **Connected:** push to an OCI registry with referrers and timestamping (Rekor‑compatible mirror).
|
||||
* **Air‑gapped:** tar+CAR archive with embedded TUF root, CRLs, and time‑stamped notary receipts.
|
||||
|
||||
**Verification UX (auditor‑friendly)**
|
||||
|
||||
* One command: `stella verify --bundle bundle.car` → prints
|
||||
(1) signature set validated, (2) replay hash match, (3) policy outcomes, (4) exceptions trail.
|
||||
|
||||
---
|
||||
|
||||
## Lightweight implementation plan (90‑day cut)
|
||||
|
||||
* **Weeks 1–3:**
|
||||
|
||||
* Extract HunkSig from upstream patches (git diff parser + normalizer).
|
||||
* Build ELF symbol/BuildID collector; store per‑distro maps.
|
||||
* **Weeks 4–6:**
|
||||
|
||||
* VEXer: matching engine + `not_affected: patched-backport` schema + ProofBlob.
|
||||
* DSSE signing with pluggable crypto providers; start with eIDAS+FIPS.
|
||||
* **Weeks 7–9:**
|
||||
|
||||
* Offline bundle format (CAR/TAR) + replay manifest + verifier CLI.
|
||||
* Policy gate: “accept if backport proof verifies”.
|
||||
* **Weeks 10–12:**
|
||||
|
||||
* Reachability subgraph export/import; deterministic re‑execution harness.
|
||||
* Docs + sample audits (openssl CVEs across Debian/Ubuntu/RHEL).
|
||||
|
||||
---
|
||||
|
||||
## UI hooks (keep it simple)
|
||||
|
||||
* **Finding:** “Backport Proofs” tab on a CVE detail → shows matched hunks and upstream commit links.
|
||||
* **Deciding:** Release diff view lists CVEs → green badges “Patched via Backport (proof‑verified)”.
|
||||
* **Auditing:** “Export Audit Pack” button at run level; pick signature profile(s); download bundle.
|
||||
|
||||
If you want, I can draft:
|
||||
|
||||
* the `HunkSig` extractor spec (inputs/outputs),
|
||||
* the VEX schema extension and DSSE envelopes,
|
||||
* the verifier CLI contract and sample CAR layout,
|
||||
* or the policy snippets to wire this into your release gates.
|
||||
Below is a developer-grade implementation guide for **patch-aware backport handling** across Alpine, Red Hat, Fedora, Debian, SUSE, Astra Linux, and “all other Linux used as Docker bases”. It is written as if you are building this inside Stella Ops (Feedser/Vexer/Sbomer/Scanner.Webservice, DSSE attestations, deterministic replay, Postgres+Valkey).
|
||||
|
||||
The key principle: **do not rely on upstream version strings**. For distros, “fixed” often means “patch backported with same NEVRA/version”. You must determine fix status by **distro patch metadata** plus **binary/source proof**.
|
||||

|
||||
|
||||
## 0) What you are building
|
||||
|
||||
### Outputs (what must exist after implementation)
|
||||
|
||||
1. **DistroFix DB** (authoritative normalized knowledge)
|
||||
|
||||
* For each distro release + package + CVE:
|
||||
|
||||
* status: affected / fixed / not_affected / under_investigation / unknown
|
||||
* fixed range expressed in distro terms (epoch/version/release or deb version) and/or advisory IDs
|
||||
* proof pointers (errata, patch commit(s), SRPM/deb source, file hashes, build IDs)
|
||||
2. **Backport Proof Engine**
|
||||
|
||||
* Given an image and its installed packages, produce a **deterministic VEX**:
|
||||
|
||||
* `status=not_affected` with `justification=patched-backport`
|
||||
* proof blob: advisory id, package build provenance, patch signatures matched
|
||||
3. **Policy integration**
|
||||
|
||||
* Gating rules treat “backport proof verified” as first-class evidence.
|
||||
4. **Replayable scans**
|
||||
|
||||
* Same inputs (feed snapshots + rules + image digest) → same verdicts.
|
||||

|
||||
|
||||
## 1) High-level approach (two-layer truth)
|
||||
|
||||
### Layer A — Distro intelligence (fast and usually sufficient)
|
||||
|
||||
For each distro, ingest its authoritative vulnerability metadata:
|
||||
|
||||
* advisory/errata streams
|
||||
* distro CVE trackers
|
||||
* security databases (Alpine secdb)
|
||||
* OVAL / CPE / CSAF if available
|
||||
* package repositories metadata
|
||||
|
||||
This provides “fixed in release X” at distro level.
|
||||
|
||||
### Layer B — Proof (needed for precision and audits)
|
||||
|
||||
When Layer A says “fixed” but the version looks “old”, prove it:
|
||||
|
||||
* **Source proof**: patch set present in source package (SRPM, debian patches, apkbuild git)
|
||||
* **Binary proof**: vulnerable function/hunk signature is patched in shipped binary (BuildID + symbol/hunk signature match)
|
||||
* **Build proof**: build metadata ties the binary to the source + patch set deterministically
|
||||
|
||||
You will use Layer B to:
|
||||
|
||||
* override false positives
|
||||
* produce auditor-grade evidence
|
||||
* operate offline with sealed snapshots
|
||||
|
||||

|
||||
|
||||
## 2) Core data model (Postgres schema guidance)
|
||||
|
||||
### 2.1 Canonical keys
|
||||
|
||||
You must normalize these identifiers:
|
||||
|
||||
* **Distro key**: `distro_family` + `distro_name` + `release` + `arch`
|
||||
|
||||
* e.g. `debian:12`, `rhel:9`, `alpine:3.19`, `sles:15sp5`, `astra:??`
|
||||
* **Package key**: canonical package name plus ecosystem type
|
||||
|
||||
* `apk`, `rpm`, `deb`
|
||||
* **CVE key**: `CVE-YYYY-NNNN`
|
||||
|
||||
### 2.2 Tables (minimum)
|
||||
|
||||
* `distro_release(id, family, name, version, codename, arch, eol_at, source)`
|
||||
* `pkg_name(id, ecosystem, name, normalized_name)`
|
||||
* `pkg_version(id, ecosystem, version_raw, version_norm, epoch, upstream_ver, release_ver)`
|
||||
* `advisory(id, distro_release_id, advisory_type, advisory_id, published_at, url, raw_json_hash, snapshot_id)`
|
||||
* `advisory_pkg(advisory_id, pkg_name_id, fixed_version_id NULL, fixed_range_json NULL, status, notes)`
|
||||
* `cve(id, cve_id, severity, cwe, description_hash)`
|
||||
* `cve_pkg_status(id, cve_id, distro_release_id, pkg_name_id, status, fixed_version_id NULL, advisory_id NULL, confidence, last_seen_snapshot_id)`
|
||||
* `source_artifact(id, type, url, sha256, size, fetched_in_snapshot_id)`
|
||||
|
||||
* SRPM, `.dsc`, `.orig.tar`, `apkbuild`, patch files
|
||||
* `patch_signature(id, cve_id, upstream_commit, file_path, function, pre_hash, post_hash, algo_version)`
|
||||
* `build_provenance(id, distro_release_id, pkg_nevra_or_debver, build_id, source_artifact_id, buildinfo_artifact_id, signer, signed_at)`
|
||||
* `binary_fingerprint(id, artifact_digest, path, elf_build_id, sha256, debuglink, arch)`
|
||||
* `proof_blob(id, subject_digest, cve_id, pkg_name_id, distro_release_id, proof_type, proof_json, sha256)`
|
||||
|
||||
### 2.3 Version comparison engines
|
||||
|
||||
Implement **three comparators**:
|
||||
|
||||
* `rpmvercmp` (RPM EVR rules)
|
||||
* `dpkg --compare-versions` equivalent (Debian version algorithm)
|
||||
* Alpine `apk` version rules (similar to semver-ish but not semver; implement per apk-tools logic)
|
||||
|
||||
Do not “approximate”. Implement exact comparators or call system libraries inside controlled container images.
|
||||
|
||||

|
||||
|
||||
## 3) Feed ingestion per distro (Layer A)
|
||||
|
||||
### 3.1 Alpine (apk)
|
||||
|
||||
**Primary data**
|
||||
|
||||
* Alpine secdb repository (per branch) mapping CVEs ↔ packages, fixed versions.
|
||||
|
||||
**Ingestion**
|
||||
|
||||
* Pull secdb for each supported Alpine branch (3.x).
|
||||
* Parse entries into `cve_pkg_status` with `fixed_version`.
|
||||
|
||||
**Package metadata**
|
||||
|
||||
* Pull `APKINDEX.tar.gz` for each repo (main/community) and arch.
|
||||
* Store package version + checksum.
|
||||
|
||||
**Notes**
|
||||
|
||||
* Alpine often explicitly lists fixed versions; backports are less “opaque” than enterprise distros, but still validate.
|
||||
|
||||
### 3.2 Red Hat Enterprise Linux (rhel) & UBI
|
||||
|
||||
**Primary data**
|
||||
|
||||
* Red Hat Security Data: CVE ↔ packages, errata, states.
|
||||
* Errata stream provides authoritative “fixed in RHSA-…”.
|
||||
|
||||
**Ingestion**
|
||||
|
||||
* For each RHEL major/minor you support (8, 9; optionally 7), pull:
|
||||
|
||||
* CVE objects + affected products + package states
|
||||
* Errata (RHSA) objects and their fixed package NEVRAs
|
||||
* Populate `advisory` + `advisory_pkg`.
|
||||
* Derive `cve_pkg_status` from errata.
|
||||
|
||||
**Package metadata**
|
||||
|
||||
* Use repository metadata (repomd.xml + primary.xml.gz) for BaseOS/AppStream/CRB, etc.
|
||||
* Record NEVRA and checksums.
|
||||
|
||||
**Enterprise backport reality**
|
||||
|
||||
* RHEL frequently backports fixes while keeping old upstream version. Your engine must prefer **errata fixed NEVRA** over upstream version meaning.
|
||||
|
||||
### 3.3 Fedora (rpm)
|
||||
|
||||
Fedora is closer to upstream; still ingest advisories.
|
||||
**Primary data**
|
||||
|
||||
* Fedora security advisories / updateinfo (often via repository updateinfo.xml.gz)
|
||||
* OVAL may exist for some streams.
|
||||
|
||||
**Ingestion**
|
||||
|
||||
* Parse updateinfo to map CVE → fixed NEVRA.
|
||||
* For Fedora rawhide/rolling, treat as high churn; snapshots must be time-bounded.
|
||||
|
||||
### 3.4 Debian (deb)
|
||||
|
||||
**Primary data**
|
||||
|
||||
* Debian Security Tracker (CVE status per release + package, fixed versions)
|
||||
* DSA advisories.
|
||||
|
||||
**Ingestion**
|
||||
|
||||
* Pull Debian security tracker data, parse per release (stable, oldstable).
|
||||
* Normalize Debian versions exactly.
|
||||
* Store “fixed in” version.
|
||||
|
||||
**Package metadata**
|
||||
|
||||
* Parse `Packages.gz` from security + main repos.
|
||||
* Optionally `Sources.gz` for source package mapping.
|
||||
|
||||
### 3.5 SUSE (SLES / openSUSE) (rpm)
|
||||
|
||||
**Primary data**
|
||||
|
||||
* SUSE security advisories (often published as CSAF; also SUSE OVAL historically)
|
||||
* Updateinfo in repos.
|
||||
|
||||
**Ingestion**
|
||||
|
||||
* Prefer CSAF/official advisory feed when available; otherwise parse `updateinfo.xml.gz`.
|
||||
* Map CVE → fixed packages.
|
||||
|
||||
### 3.6 Astra Linux (deb-family, often)
|
||||
|
||||
Astra is niche and may have bespoke advisories/mirrors.
|
||||
**Primary data**
|
||||
|
||||
* Astra security bulletins and repository metadata.
|
||||
* If they publish a tracker or advisories in a machine-readable format, ingest it; otherwise:
|
||||
|
||||
* treat repo metadata + changelogs as the canonical signal.
|
||||
|
||||
**Ingestion strategy**
|
||||
|
||||
* Implement a generic “Debian-family fallback”:
|
||||
|
||||
* ingest `Packages.gz` and `Sources.gz` from Astra repos
|
||||
* ingest available security bulletin feed (HTML/JSON); parse with a deterministic extractor
|
||||
* if advisories are sparse, rely on Layer B proof more heavily (source patch presence + binary proof)
|
||||
|
||||
### 3.7 “All other Linux used on docker repositories”
|
||||
|
||||
Handle this by **distro families** plus a plugin pattern:
|
||||
|
||||
* Debian family (Ubuntu, Kali, Astra, Mint): use Debian comparator + `Packages/Sources` + their security tracker if exists
|
||||
* RPM family (RHEL clones: Rocky/Alma/Oracle; Amazon Linux): rpm comparator + updateinfo/OVAL/errata equivalents
|
||||
* Alpine family (Wolfi/apko-like): their own secdb or APKINDEX equivalents
|
||||
* Distroless/scratch: no package manager; you must fall back to binary scanning only (Layer B).
|
||||
|
||||
**Developer action**
|
||||
|
||||
* Create an interface `IDistroProvider` with:
|
||||
|
||||
* `EnumerateReleases()`
|
||||
* `FetchAdvisories(snapshot)`
|
||||
* `FetchRepoMetadata(snapshot)`
|
||||
* `NormalizePackageName(...)`
|
||||
* `CompareVersions(a,b)`
|
||||
* `ParseInstalledPackages(image)` (if package manager exists)
|
||||
* Implement providers: `AlpineProvider`, `DebianProvider`, `RpmProvider`, `SuseProvider`, `AstraProvider`, plus “GenericDebianFamilyProvider”, “GenericRpmFamilyProvider”.
|
||||
|
||||

|
||||
|
||||
## 4) Installed package extraction (inside scan)
|
||||
|
||||
### 4.1 Determine OS identity
|
||||
|
||||
From image filesystem:
|
||||
|
||||
* `/etc/os-release` (ID, VERSION_ID)
|
||||
* distro-specific markers:
|
||||
|
||||
* Alpine: `/etc/alpine-release`
|
||||
* Debian: `/etc/debian_version`
|
||||
* RHEL: `/etc/redhat-release`
|
||||
|
||||
Write a deterministic resolver:
|
||||
|
||||
* if `/etc/os-release` missing, fall back to:
|
||||
|
||||
* package DB presence: `/lib/apk/db/installed`, `/var/lib/dpkg/status`, rpmdb paths
|
||||
* ELF libc fingerprint heuristics (last resort)
|
||||
|
||||
### 4.2 Extract installed packages deterministically
|
||||
|
||||
* Alpine: parse `/lib/apk/db/installed`
|
||||
* Debian: parse `/var/lib/dpkg/status`
|
||||
* RPM: parse rpmdb (use `rpm` tooling in a controlled helper container, or implement rpmdb reader; prefer tooling for correctness)
|
||||
|
||||
Store:
|
||||
|
||||
* package name
|
||||
* version string (raw)
|
||||
* arch
|
||||
* source package mapping if available (Debian’s `Source:` fields; RPM’s `Sourcerpm`)
|
||||
|
||||
---
|
||||
|
||||
## 5) The backport proof engine (Layer B)
|
||||
|
||||
This is the “precision jump”. It has three proof modes; implement all three and choose best available.
|
||||
|
||||
### Proof mode 1 — Advisory fixed NEVRA/version match (fast)
|
||||
|
||||
If the distro’s errata/DSA/updateinfo says fixed in `X`, and installed package version compares ≥ X (using correct comparator):
|
||||
|
||||
* mark fixed with `confidence=high`
|
||||
* attach advisory reference only
|
||||
|
||||
This already addresses many cases.
|
||||
|
||||
### Proof mode 2 — Source patch presence (best for distros with source repos)
|
||||
|
||||
Prove the patch is in the source package even if version looks old.
|
||||
|
||||
#### Debian-family
|
||||
|
||||
* Determine source package:
|
||||
|
||||
* from `dpkg status` “Source:” if present; otherwise map binary→source via `Sources.gz`
|
||||
* Fetch source:
|
||||
|
||||
* `.dsc` + referenced tarballs + `debian/patches/*` (or `debian/patches/series`)
|
||||
* Patch signature verification:
|
||||
|
||||
* For CVE, you maintain `patch_signature` derived from upstream fix commits:
|
||||
|
||||
* identify file/function/hunk; store normalized diff hashes (ignore whitespace/context drift)
|
||||
* Apply:
|
||||
|
||||
* check if any distro patch file contains the “post” signature (or the vulnerable code is absent)
|
||||
* Record in `proof_blob`:
|
||||
|
||||
* source artifact SHA256
|
||||
* patch file names
|
||||
* matching signature IDs
|
||||
* deterministic verifier log
|
||||
|
||||
#### RPM-family (RHEL/Fedora/SUSE)
|
||||
|
||||
* Determine SRPM from installed RPM metadata (Sourcerpm field).
|
||||
* Fetch SRPM from source repo (or debug/source channel).
|
||||
* Extract patches from SRPM spec + sources.
|
||||
* Verify patch signatures as above.
|
||||
|
||||
#### Alpine
|
||||
|
||||
* Determine `apkbuild` and patches for the package version (Alpine aports)
|
||||
* Verify patch signature.
|
||||
|
||||
### Proof mode 3 — Binary hunk/signature match (works even without source repos)
|
||||
|
||||
This is your universal fallback (also for distroless).
|
||||
|
||||
#### Build fingerprints
|
||||
|
||||
* For each ELF binary in the package or image:
|
||||
|
||||
* compute `sha256`
|
||||
* read `ELF BuildID` if present
|
||||
* capture `.gnu_debuglink` if present
|
||||
* capture symbols (when available)
|
||||
|
||||
#### Signature strategy
|
||||
|
||||
For each CVE fix, create one or more **binary-checkable predicates**:
|
||||
|
||||
* vulnerable function contains a known byte sequence that disappears after fix
|
||||
* or patched function includes a new basic block pattern
|
||||
* or a string constant changes (weak, but sometimes useful)
|
||||
* or the compile-time feature toggles
|
||||
|
||||
Implement as `BinaryPredicate` objects:
|
||||
|
||||
* `type`: bytepattern | cfghash | symbolrangehash | rodata-string
|
||||
* `scope`: file path patterns / package name constraints
|
||||
* `arch`: x86_64/aarch64 etc.
|
||||
* `algo_version`: so you can evolve without breaking replay
|
||||
|
||||
Evaluation:
|
||||
|
||||
* locate candidate binaries (package manifest, common library paths)
|
||||
* apply predicate in a stable order
|
||||
* if “fixed predicate” matches and “vulnerable predicate” does not:
|
||||
|
||||
* produce proof
|
||||
|
||||
#### Evidence quality
|
||||
|
||||
Binary proof must include:
|
||||
|
||||
* file path + sha256
|
||||
* BuildID if available
|
||||
* predicate ID + algorithm version
|
||||
* extractor/verifier version hashes
|
||||
|
||||

|
||||
|
||||
## 6) Building the patch signature corpus (no humans)
|
||||
|
||||
### 6.1 Upstream patch harvesting (Feedser)
|
||||
|
||||
For each CVE:
|
||||
|
||||
* find upstream fix commits (NVD references, project advisories, distro patch references)
|
||||
* fetch git diffs
|
||||
* normalize to `patch_signature`:
|
||||
|
||||
* (file path, function name if detectable, pre hash, post hash)
|
||||
* store multiple signatures per CVE if multiple upstream branches
|
||||
|
||||
You will not always find perfect fix commits. When missing:
|
||||
|
||||
* fall back to distro-specific patch extraction (learn signatures from distro patch itself)
|
||||
* mark `signature_origin=distro-learned` but keep it auditable
|
||||
|
||||
### 6.2 Deterministic normalization rules
|
||||
|
||||
* strip diff metadata that varies
|
||||
* normalize whitespace
|
||||
* compute hashes over:
|
||||
|
||||
* token stream (C/C++ tokens; for others line-based)
|
||||
* include hunk context windows
|
||||
* store `algo_version` and never change semantics without bumping
|
||||
|
||||
---
|
||||
|
||||
## 7) Decision algorithm (deterministic, ordered, explainable)
|
||||
|
||||
For each `(image_digest, distro_release, pkg, cve)`:
|
||||
|
||||
1. **If distro provider has explicit status “not affected”** (e.g., vulnerable code not present in that distro build):
|
||||
|
||||
* emit VEX not_affected with advisory proof
|
||||
2. **Else if advisory says fixed in version/NEVRA** and installed compares as fixed:
|
||||
|
||||
* emit VEX fixed with advisory proof
|
||||
3. **Else if source proof succeeds**:
|
||||
|
||||
* emit VEX not_affected / fixed (depending on semantics) with `justification=patched-backport`
|
||||
4. **Else if binary proof succeeds**:
|
||||
|
||||
* emit VEX not_affected / fixed with binary proof
|
||||
5. Else:
|
||||
|
||||
* affected/unknown depending on policy, but always attach “why unknown” in evidence.
|
||||
|
||||
This order is critical to keep runtime reasonable and proofs consistent.
|
||||
|
||||
---
|
||||
|
||||
## 8) Engineering constraints for Docker base images
|
||||
|
||||
### 8.1 Multi-stage images and removed package DBs
|
||||
|
||||
Many production images delete package databases to slim.
|
||||
Your scan must handle:
|
||||
|
||||
* no dpkg status, no rpmdb, no apk db
|
||||
In this case:
|
||||
* try SBOM from build provenance (if you have it)
|
||||
* otherwise treat as **binary-only**:
|
||||
|
||||
* scan ELF binaries + shared libs
|
||||
* map to known package/binary fingerprints where possible
|
||||
* rely on Proof mode 3
|
||||
|
||||
### 8.2 Minimal images (distroless, scratch)
|
||||
|
||||
* There is no OS metadata; don’t pretend.
|
||||
* Mark distro as `unknown`, skip Layer A, go straight to binary proof.
|
||||
* Policy should treat unknowns explicitly (your existing “unknown budget” moat).
|
||||
|
||||
---
|
||||
|
||||
## 9) Implementation structure in .NET 10 (practical module map)
|
||||
|
||||
### 9.1 Services and boundaries
|
||||
|
||||
* **Feedser**
|
||||
|
||||
* pulls distro advisories/trackers/repo metadata
|
||||
* produces normalized `DistroFix` snapshots
|
||||
* **Sbomer**
|
||||
|
||||
* produces SBOM + captures file fingerprints, BuildIDs
|
||||
* **Scanner.Webservice**
|
||||
|
||||
* runs the deterministic evaluation and lattice/policy logic (per your standing rule)
|
||||
* does proof verification + emits signed verdicts
|
||||
* **Vexer**
|
||||
|
||||
* aggregates VEX claims + attaches proof blobs (but evaluation logic stays in Scanner.Webservice)
|
||||
* **Authority/Attestor**
|
||||
|
||||
* DSSE signing, OCI referrers, audit pack exports
|
||||
|
||||
### 9.2 Core libraries
|
||||
|
||||
Create a library `StellaOps.Security.Distro`:
|
||||
|
||||
* `IDistroProvider`
|
||||
* `IVersionComparator`
|
||||
* `IInstalledPackageExtractor`
|
||||
* `IAdvisoryParser`
|
||||
* `ISourceProofVerifier`
|
||||
* `IBinaryProofVerifier`
|
||||
|
||||
Each provider implements:
|
||||
|
||||
* parsing
|
||||
* comparator
|
||||
* extraction for its ecosystem
|
||||
|
||||
### 9.3 Determinism rules (must be enforced)
|
||||
|
||||
* Every scan references a specific `snapshot_id` for feeds.
|
||||
* Proof computations are pure functions of:
|
||||
|
||||
* image digest
|
||||
* extracted artifacts
|
||||
* snapshot content hashes
|
||||
* algorithm version hashes
|
||||
* Logs included in proof blobs must be stable (no timestamps unless separately recorded).
|
||||
|
||||
---
|
||||
|
||||
## 10) Test strategy (non-negotiable)
|
||||
|
||||
### 10.1 Golden corpus images
|
||||
|
||||
Build a repo of fixtures:
|
||||
|
||||
* `alpine:3.18`, `alpine:3.19`
|
||||
* `debian:11`, `debian:12`
|
||||
* `ubuntu:22.04`, `ubuntu:24.04`
|
||||
* `ubi9`, `ubi8` (or rhel-like equivalents you can legally test)
|
||||
* `fedora:40+`
|
||||
* `opensuse/leap`, `sles` if accessible
|
||||
* Astra base images if you use them internally
|
||||
|
||||
For each fixture:
|
||||
|
||||
* pick 10 known CVEs across openssl, curl, zlib, glibc, libxml2
|
||||
* store expected decisions:
|
||||
|
||||
* vulnerable vs fixed, including backported cases
|
||||
* run in CI with locked snapshots
|
||||
|
||||
### 10.2 Comparator test suites
|
||||
|
||||
For RPM and Debian version compare:
|
||||
|
||||
* ingest official comparator test vectors (or recreate known tricky cases)
|
||||
* unit tests must include:
|
||||
|
||||
* epoch handling
|
||||
* tilde ordering in Debian versions
|
||||
* rpm release ordering
|
||||
|
||||
### 10.3 Proof verifier tests
|
||||
|
||||
* source proof: patch signature detection on extracted SRPM/deb sources
|
||||
* binary proof: fixed/vulnerable predicate detection on controlled binaries
|
||||
|
||||
---
|
||||
|
||||
## 11) Practical rollout plan (how developers should implement)
|
||||
|
||||
### Phase 1 — Layer A for all major distros (fast coverage)
|
||||
|
||||
1. Implement comparators: rpm, deb, apk.
|
||||
2. Implement providers:
|
||||
|
||||
* Alpine secdb + APKINDEX
|
||||
* Debian security tracker + Packages/Sources
|
||||
* RHEL errata/CVE feed + repo metadata
|
||||
* Fedora updateinfo + repo metadata
|
||||
* SUSE advisory/updateinfo
|
||||
* Generic Debian/RPM fallback providers
|
||||
3. Produce `cve_pkg_status` snapshots and basic VEX results using only Layer A.
|
||||
|
||||
### Phase 2 — Source proof (removes most false positives)
|
||||
|
||||
1. Implement upstream patch harvesting → `patch_signature`.
|
||||
2. Implement Debian source fetch + verification.
|
||||
3. Implement SRPM fetch + verification.
|
||||
4. Wire into decision algorithm, emit proof blobs.
|
||||
|
||||
### Phase 3 — Binary proof (covers stripped/minimal images)
|
||||
|
||||
1. Implement ELF fingerprint extraction + BuildID store.
|
||||
2. Implement predicate framework + initial predicates for top libraries.
|
||||
3. Add caching (Valkey) for predicate results keyed by `(file sha256, predicate_id, algo_version)`.
|
||||
|
||||
### Phase 4 — Astra and niche distros hardening
|
||||
|
||||
1. Implement Astra provider:
|
||||
|
||||
* repo metadata ingestion
|
||||
* advisory parsing if available
|
||||
* otherwise rely on source/binary proof
|
||||
2. Add distro onboarding kit:
|
||||
|
||||
* define endpoints for repo metadata
|
||||
* define advisory parsing rules
|
||||
* define comparator family
|
||||
|

|
||||
|
||||
## 12) What “done” means (acceptance criteria)
|
||||
|
||||
A developer story is “complete” only if:
|
||||
|
||||
* For each supported distro family, you can:
|
||||
|
||||
* identify distro release
|
||||
* extract installed packages OR fall back to binary-only
|
||||
* compute fix status for at least top 50 packages
|
||||
* produce VEX with either advisory or proof
|
||||
* At least 100 backport scenarios across RHEL/Debian/SUSE pass golden tests.
|
||||
* Scan is replayable:
|
||||
|
||||
* freeze snapshot, rerun, identical verdict hash.
|
||||
|
||||
---
|
||||
|
||||
If you want this converted into your internal sprintable format (epics/stories/tasks + acceptance tests + file/module layout in a .NET 10 repo), I can output it as:
|
||||
|
||||
* `SPECS.md` section “Patch-aware Backport Handling”
|
||||
* `CONTRACTS.md` (provider interfaces, proof blob schema, DSSE envelopes)
|
||||
* `DB_REPOSITORIES.md` migrations outline
|
||||
* `IMPLEMENTATION.md` with step-by-step task breakdown per distro.

## 📝 Notes
|
||||
|
||||
- All C# code follows .NET 10 conventions with latest C# preview features
|
||||
- Determinism is enforced via canonical JSON serialization and sorted collections
|
||||
- Offline-first design: no hard-coded external dependencies
|
||||
- Air-gap support: signatures verifiable without network
|
||||
- Feature-flagged: `VerdictAttestationsEnabled` defaults to `false` for safety

Here’s a crisp snapshot of what matters most from the latest docs and feature rollouts across Snyk Container, Anchore Enterprise, and Prisma Cloud—and how they compare to what *Stella Ops* is positioning as its next‑gen differentiators.
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
**Enterprise development and security teams are demanding not just vulnerability data, but context, historical evidence, and seamless exportability—across SBOM/VEX, audit trails, and internal policy workflows.**
|
||||
|
||||
---
|
||||
|
||||
### 🔎 Snyk UI – Base‑Image Detection + Custom Base Image Recommendations
|
||||
|
||||
* Snyk automatically detects a container’s base image from a Dockerfile or image manifest and surfaces vulnerabilities tied to that base layer. This helps you see *where risk originates* in the image stack. ([Snyk User Docs][1])
|
||||
* Its *Custom Base Image Recommendations* (CBIR) feature lets organizations define an internal pool of approved base images and suggests upgrades from that pool during scans—not just public Docker images. You can attach Dockerfiles, configure versioning schemas, and even trigger automated PRs to bump base image versions. ([Snyk User Docs][2])
|
||||
|
||||
👉 This shifts the guidance from generic upgrade hints to curated, internal‑policy‑aligned suggestions.
|
||||
|
||||
---
|
||||
|
||||
### 📊 Anchore Enterprise – UI‑Driven Vulnerability Annotations & VEX Export
|
||||
|
||||
* Anchore Enterprise now supports annotating vulnerabilities *via the UI* or API, capturing states like “mitigated,” “in review,” or “scheduled for fix.” Those annotations improve clarity on whether a finding truly matters. ([Anchore Documentation][3])
|
||||
* You can export this context‑rich analysis as *VEX* in both **OpenVEX** and **CycloneDX** formats—complete with package PURLs and metadata—making it compatible with broader SBOM ecosystems and supply‑chain tooling. ([Anchore][4])
|
||||
|
||||
👉 This turns Anchore from a scanner into a *vulnerability narrative engine* that you can share downstream.
|
||||
|
||||
---
|
||||
|
||||
### 📁 Prisma Cloud – Admin Audit Trails & Compliance History
|
||||
|
||||
* Prisma Cloud logs *every administrative activity* (settings changes, rule modifications, configuration edits) and you can review these in the console. These audit trails exist both in the UI and accessible via API for compliance and forensic needs. ([Prisma Cloud Documentation][5])
|
||||
* Prisma stores historical audit events across major subsystems (not just admin changes), meaning you can trace what changed, when, and by whom. ([Prisma Cloud Documentation][6])
|
||||
|
||||
👉 This is useful for security governance, post‑incident review, and auditor evidence.
|
||||
|
||||
---
|
||||
|
||||
### ⚡ Stella Ops Differentiators – Conceptual Guidance
|
||||
|
||||
While the products above deliver strong diagnostics, annotations, and historical logs, *Stella Ops* aims to elevate **trust and auditability** by design:
|
||||
|
||||
* **Signed delta‑verdicts:** cryptographically bound verdicts for every policy evaluation (ideal for assuring automation and downstream consumers that data hasn’t changed).
|
||||
* **Reachability proof panels:** visual evidence of *why* a finding or verdict applies—beyond just SBOM entries.
|
||||
* **Replayable evidence packs:** a *time‑stamped, queryable bundle* of scan, policy, and context data that can be replayed for audits or incident reviews.
|
||||
|
||||
These go beyond just exporting data: they bind *evidence to logic and trust*.

|
||||
1. Virtual scrolling for large graphs (1000+ nodes)
|
||||
2. Real-time WebSocket updates for proof chains

Here’s a compact, practical plan for surfacing **replayable risk verdicts** in Stella Ops so users can *see* input–output determinism and what changed between releases.
|
||||
|
||||

|
||||
|
||||
# Why this matters (quick background)
|
||||
|
||||
* A **verdict** = the platform’s signed decision about risk (e.g., “deployable,” “blocked,” “needs review”), computed from inputs (SBOM, reachability, signatures, policies, VEX, env facts).
|
||||
* **Replayable** = same inputs → same verdict (byte‑for‑byte), provable via content‑addressed manifests and attestations.
|
||||
* Users often ask: “What changed since last release?” A **delta verdict** answers that with a cryptographically signed diff of evidence and policy effects.
|
||||

||||

||||
# Minimal UX (MVP) — one view, three panes
|
||||
|
||||
1. **Header strip**
|
||||
|
||||
* Artifact@version • Environment • Policy profile • Verdict (badge) • Signature status • “Replay” button • “Export attestations” button.
|
||||
|
||||
2. **Smart Diff (center)**
|
||||
|
||||
* Tabs: **Evidence**, **Policies**, **Impact**.
|
||||
* Each tab shows **Delta Objects** (diffable cards), each signed:
|
||||
|
||||
* Evidence deltas (SBOM nodes, reachability subgraphs, VEX claims, signatures, runtime facts).
|
||||
* Policy deltas (changed rules, thresholds, exceptions).
|
||||
* Impact deltas (risk budget movement, affected services, deploy gates).
|
||||
|
||||
3. **Explainable Triage (right)**
|
||||
|
||||
* Collapsible causality chain:
|
||||
|
||||
* “Verdict = Blocked”
|
||||
↳ due to Policy R‑17 (“fail if unknowns>0 in prod”)
|
||||
↳ because Evidence:E‑UNK‑42 (package `libxyz` hash H…)
|
||||
↳ reachable via Subgraph G‑a12 (entry→…→libxyz)
|
||||
↳ vendor VEX absent for CVE‑2025‑1234
|
||||
* Each node links back to its **Delta Object** and raw payload.
|
||||
|
||||
> Result: Smart Diff + Explainable Triage unified in one screen; diffs tell *what changed*, the triage rail tells *why it changed*.

# Core objects (signed & diffable)
|
||||
|
||||
* **Verdict** (`verdict.jsonld`):
|
||||
|
||||
* `inputs`: CIDs for SBOM, Reachability, Policies, VEX sets, Env facts
|
||||
* `decision`: enum + score + rationale hash
|
||||
* `evidence_refs[]`: CIDs of normalized evidence bundles
|
||||
* `policy_trace[]`: ordered rule hits with pre/post states
|
||||
* `provenance`: in‑toto/DSSE, signer, algo (Ed25519 / optional PQ)
|
||||
* `replay_hint`: docker image digests, feed snapshots, clock fence
|
||||
* **Delta Verdict** (`verdict.delta.jsonld`):
|
||||
|
||||
* `base_verdict_cid`, `head_verdict_cid`
|
||||
* `diffs[]`: typed ops (add/remove/modify) over normalized graphs
|
||||
* `risk_budget_delta`, `gate_effects[]` (which gates flipped)
|
||||
* `signatures[]` (platform, optional vendor co‑sign)
|
||||
|
||||
All objects stored/content‑addressed in **Authority** (Postgres SOR; Valkey cache) and attachable to OCI artifacts as attestations.

# UI interactions (MVP flow)
|
||||
|
||||
* Select two runs (e.g., `app:payments` @ `2025‑12‑20` vs `2025‑12‑23`) → **Compute/Load Delta Verdict** → render cards.
|
||||
* Click any card → left shows raw JSON, right shows **cause chain**.
|
||||
* “Replay” → spins a deterministic runner with frozen inputs (feed pins, policy version, env snapshot) → emits **replayed verdict** with new timestamp, same content hash expected.
|
||||
|
||||
---
|
||||
|
||||
# Visual design hints
|
||||
|
||||
* Keep it **diff‑first**: green (+), red (–), gray (unchanged).
|
||||
* Pin **trust badges** on each card (Signed/Unsigned, Verifier OK/Fail).
|
||||
* Show **unknowns** and **assumptions** as chips (count + hover detail).
|
||||
* One click to **“Open as Evidence Pack”** (ZIP with all referenced CIDs).
|
||||
|
||||

|
||||
|
||||
# API sketch (internal)
|
||||
|
||||
* `GET /verdicts/{cid}` → full verdict
|
||||
* `POST /verdicts/diff` → body: `{base: cid, head: cid}` → delta verdict
|
||||
* `POST /verdicts/replay` → body: `{cid}` → new run with frozen inputs
|
||||
* `GET /evidence/{cid}` → normalized bundle (SBOM, subgraph, VEX, sigs)
|
||||
* `GET /policy-trace/{cid}` → ordered rule hits + bindings
|
||||
|
||||
---
|
||||
|
||||
# Normalization & determinism (must‑haves)
|
||||
|
||||
* Canonical JSON (JCS), sorted maps/lists, stable IDs.
|
||||
* Graph hashing (Merkle over node/edge tuples).
|
||||
* Feed pinning (timestamped snapshots with source checksums).
|
||||
* DSSE envelopes; Rekor‑compatible log proof (or mirror).
|
||||
|
||||
---
|
||||
|
||||
# Rollout plan (3 sprints)
|
||||
|
||||
**S1**: Canonicalization library, Verdict object, Delta over SBOM+Policies, UI skeleton with diff cards.
|
||||
**S2**: Reachability subgraph deltas, policy‑trace explainer, signatures & verify badges, export packs.
|
||||
**S3**: Replay runner with freeze‑frame inputs, gate effects view, OCI attestation attach/read.
|
||||
|
||||
---
|
||||
|
||||
# Acceptance criteria (MVP)
|
||||
|
||||
* Given identical inputs, **replay** reproduces byte‑identical verdict CID.
|
||||
* Delta view pinpoints *exact* evidence/policy changes in <2 clicks.
|
||||
* Each delta object displays signature status and source.
|
||||
* Exported evidence pack re‑computes the same verdict on air‑gapped node.
