مخرجات التعلم
- Run software composition analysis and triage findings by exploitability and reachability.
- Generate an SBOM (CycloneDX) for services and images.
- Scan container images and pin base images.
- Explain supply-chain risks (typosquatting, compromised builds) and controls (signing, provenance).

Lab
MID-053-LAB1 · Secure builds
Outcomes: 1–4 · Time: ~2 h Add SCA, a CycloneDX SBOM, and an image scan to every Shop pipeline. Add a severity gate (fail on critical/high unless an exception exists) and an exceptions file with reason, owner, and expiry. Pin base images. Plant one vulnerable dependency to prove the gate. Acceptance: a planted vulnerable dependency fails the build; SBOMs are stored as build artifacts.
Exercises (assessment: triage exercise)
| ID | Outcome | Task |
|---|---|---|
| MID-053-EX01 | 1 | Triage five given findings: decide fix, mitigate, or accept for each, with reasons. |
| MID-053-EX02 | 1 | Explain why a critical CVE in a test-scope library may rank below a medium one in a public endpoint's code path. |
| MID-053-EX03 | 2 | Generate a CycloneDX SBOM for orders and find which version of Jackson it contains. |
| MID-053-EX04 | 3 | Scan the orders image, list the top findings, and reduce them by changing the base image. |
| MID-053-EX05 | 4 | Describe typosquatting and name two controls against it. |
| MID-053-EX06 | 4 | Draw a pipeline that signs the image and a cluster policy that rejects unsigned images. |
أظهر الحلول
- EX01 Fix when reachable and exposed; mitigate (config, WAF, disable feature) when no fix exists; accept only when unreachable, with an expiry date and owner.
- EX02 Test-scope code is not shipped, while the medium finding is reachable by an attacker; exploitability and exposure matter beyond severity.
- EX03 Plugin goal
makeAggregateBom; search the JSONcomponentsforjackson-databindand read itsversion. - EX04 Example:
trivy image, then switch to a slim or distroless maintained base, rebuild, and re-scan; findings drop because fewer OS packages are present. - EX05 A package with a name close to a popular one that contains malware. Controls: lock files and checksum verification, an internal proxy with an allowlist, review new dependencies.
- EX06 Build → push → cosign sign (keyless or key-based) → admission policy verifies the signature before a pod starts (verify tool names before use).
Outcome 2 is also covered by the lab criterion "SBOMs stored as build artifacts" and quiz Q04.

الجزء العملي
Triage exercise (MID-053-EX01) plus lab MID-053-LAB1. Pass: quiz at least 8/10, a correct triage with reasons, and a planted vulnerable dependency failing the build.
أخطاء شائعة
Ignoring all findings due to noise; never updating base images.
