In this tutorial, you'll learn how Score Proofs provide cryptographic guarantees that your vulnerability scores are reproducible and verifiable. + +**[Screen: Terminal]** + +> Let's start with a typical vulnerability scan. Here I have an SBOM for my application. + +```bash +stella scan --sbom ./sbom.json +``` + +> The scan produces findings, but how do we know these results are accurate? Can we prove they're reproducible? + +**[Screen: Terminal - enable proofs]** + +> Let's run the same scan with proof generation enabled. + +```bash +stella scan --sbom ./sbom.json --generate-proof --output ./scan-results/ +``` + +> Notice the `--generate-proof` flag. StellaOps now creates a cryptographic attestation alongside the findings. + +**[Screen: File browser showing proof bundle]** + +> Here's what got generated: +> - `manifest.json` contains content-addressed references to every input +> - `proof.dsse` is the signed attestation +> - `findings.json` has the actual vulnerability results + +**[Screen: Terminal - verify]** + +> Anyone with this bundle can verify the proof: + +```bash +stella proof verify ./scan-results/proof.dsse +``` + +> The signature is valid, and we can see exactly which inputs produced these results. + +**[Screen: Terminal - replay]** + +> We can even replay the scan to prove determinism: + +```bash +stella score replay ./scan-results/ --verify +``` + +> Same inputs produce the exact same outputs. This is powerful for audits and compliance. + +**[Closing]** + +> That's Score Proofs in action. For more details, check the documentation or watch our deep-dive tutorials. + +--- + +## Video 2: Understanding Reachability Analysis (7 min) + +### Script + +**[Opening]** + +> Vulnerability scanners often overwhelm teams with alerts. Reachability analysis helps you focus on what actually matters. + +**[Screen: Slide showing vulnerability count]** + +> Imagine your scanner finds 200 vulnerabilities. Studies show 80-90% are unreachable—the vulnerable code path never executes in your application. + +**[Screen: Terminal]** + +> Let's see reachability in action. First, we generate a call graph: + +```bash +stella scan graph ./src --output ./callgraph.json +``` + +> This analyzes your source code to map function calls. + +**[Screen: Visualization of call graph]** + +> The call graph shows which functions call which. Starting from your entry points, we can trace all possible execution paths. + +**[Screen: Terminal - scan with reachability]** + +> Now let's scan with reachability enabled: + +```bash +stella scan --sbom ./sbom.json --call-graph ./callgraph.json --reachability +``` + +**[Screen: Results showing reachability verdicts]** + +> Look at the results: +> - CVE-2024-1234: `REACHABLE_STATIC` - this IS on an executable path +> - CVE-2024-5678: `NOT_REACHABLE` - safely ignore this one +> - CVE-2024-9012: `POSSIBLY_REACHABLE` - needs review + +**[Screen: Terminal - filter]** + +> We can filter to only actionable items: + +```bash +stella query --filter "reachability=REACHABLE_STATIC" +``` + +> From 200 findings, we're now focused on 20 that actually matter. + +**[Screen: Diagram showing path]** + +> For reachable vulnerabilities, we can see the exact path: + +```bash +stella reachability explain --cve CVE-2024-1234 +``` + +> `Main.java:15` calls `Service.java:42`, which calls the vulnerable function. + +**[Closing]** + +> Reachability analysis transforms alert fatigue into focused action.
