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*.

|
||||
## Known Issues & Limitations
|
||||
|
||||
### Pre-Existing Issues (Not Related to Sprint 4200)
|
||||
1. **PredicateSchemaValidator.cs** - Missing Json.Schema NuGet package reference
|
||||
2. **Cryptography warnings** - Obsolete Dilithium API usage (upstream BouncyCastle)
|
||||
|
||||
### Sprint 4200 Limitations (By Design)
|
||||
1. **Cytoscape.js not bundled** - Requires `npm install` (documented)
|
||||
2. **No mock API data** - Integration tests need mock responses (pending)
|
||||
3. **PDF export placeholder** - JSON/Markdown implemented, PDF uses browser print
|
||||
|
||||
### Recommended Enhancements (Future Work)
|
||||
1. Virtual scrolling for large graphs (1000+ nodes)
|
||||
2. Real-time WebSocket updates for proof chains
|
||||
3. Proof chain comparison view
|
||||
4. Export graph as PNG/SVG
|
||||
5. Advanced graph layout algorithms

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.
