Engineering Security Architecture

14 / 15

Given a system/architecture description, produce five deliverables in order:

  1. Threat Map — actors, assets, entry points, threat vectors
  2. Attack Surface — enumerated exposed components and interfaces
  3. Security Controls — Zero Trust controls mapped to each risk
  4. Mitigation Plan — prioritized remediation with owners/timelines
  5. Audit Checklist — verifiable pass/fail items for compliance

Example trigger: "Review the security posture of our microservices API gateway with JWT auth."

Recommendation
Add a second example with a different system type (e.g., data pipeline or mobile app) to show adaptability beyond API gateway scenarios

Progress:

  • Step 1: Gather system context (architecture, data flows, trust boundaries, identities)
  • Step 2: Build Threat Map (STRIDE-based: Spoofing, Tampering, Repudiation, Info Disclosure, DoS, Elevation of Privilege)
  • Step 3: Enumerate Attack Surface (network, API, IAM, supply chain, runtime)
  • Step 4: Map Security Controls using Zero Trust pillars (Identity, Device, Network, Application, Data)
  • Step 5: Draft Mitigation Plan (severity-ranked, actionable, assigned)
  • Step 6: Produce Audit Checklist (testable, binary outcomes)

Step 1: Gather Context

Identify: assets (data, services), trust boundaries, identity providers, network topology, third-party dependencies. If context is incomplete, state explicit assumptions rather than halting.

Step 2: Threat Map

For each asset, list: threat actor → attack vector → STRIDE category → impact (Low/Med/High/Critical) → likelihood.

Step 3: Attack Surface

Categorize exposure:

  • External: public APIs, ingress points, exposed ports
  • Internal: service-to-service calls, internal admin panels
  • IAM: privileged roles, service accounts, token lifetimes
  • Runtime: containers, orchestrators, sidecars, secrets at runtime
  • Supply Chain: dependencies, CI/CD, third-party integrations

Step 4: Security Controls (Zero Trust)

Map each attack surface item to control:

  • Identity: MFA, short-lived tokens, least privilege
  • Device: posture checks, endpoint attestation
  • Network: microsegmentation, mTLS, no implicit trust
  • Application: input validation, WAF, secure SDLC
  • Data: encryption at rest/in transit, DLP, classification

Step 5: Mitigation Plan

Format: [Severity] Issue → Recommended Fix → Owner → ETA → Verification Method Rank Critical > High > Medium > Low. Critical items must have compensating controls if immediate fix isn't feasible.

Step 6: Audit Checklist

Each item must be binary (Pass/Fail), traceable to a control, and testable (manual or automated).

Recommendation
Include a 'bad output' example illustrating a poorly-formed mitigation plan (untriaged, vague) to contrast with the good one

Example 1:

Input: "API gateway with JWT auth, no mTLS between services, admin panel exposed to VPN only, secrets stored in env vars."

Attack Surface

  • External: public gateway endpoints, JWT validation logic
  • Internal: unencrypted service mesh traffic
  • IAM: JWT signing keys, token TTL/refresh flow
  • Runtime: secrets in env vars (visible via /proc, container inspect)
  • Supply Chain: not assessed (no dependency data provided)

Security Controls

  • Identity: rotate JWT signing keys, enforce short TTL (≤15min) + refresh tokens
  • Network: enforce mTLS mesh-wide (e.g., Istio/Linkerd)
  • Data: migrate secrets to vault (e.g., HashiCorp Vault/K8s Secrets + encryption)
  • Application: rate-limit gateway, validate JWT aud/iss claims strictly

Mitigation Plan

  1. [Critical] Secrets in env vars → Migrate to secrets manager → Platform Team → 1 week → Verify via container inspection
  2. [High] No mTLS → Deploy service mesh mTLS → Infra Team → 2 weeks → Verify via traffic capture
  3. [Medium] Long JWT TTL → Reduce to 15min + refresh flow → Backend Team → 3 days → Verify via token decode test

Audit Checklist

  • Secrets not present in plaintext env vars (Pass/Fail)
  • All inter-service traffic encrypted via mTLS (Pass/Fail)
  • JWT TTL ≤ 15 minutes (Pass/Fail)
  • Admin panel requires MFA in addition to VPN (Pass/Fail)
Recommendation
Rename skill to gerund form more explicitly aligned with action, e.g. 'architecting-security-controls' for stronger naming consistency
  • Always assume breach (Zero Trust core tenet) — no implicit trust for internal traffic.
  • Quantify severity/likelihood consistently; avoid vague labels without justification.
  • Tie every control back to a specific threat, not generic best practice.
  • Prefer compensating controls over blocking delivery when fixes take time.
  • Make audit checklist items independently verifiable by someone without full context.
  • Don't produce a Mitigation Plan without a preceding Threat Map — recommendations must trace to identified risks.
  • Don't treat perimeter security as sufficient; internal/lateral threats must be modeled.
  • Don't leave severity/priority unranked — untriaged lists are not actionable.
  • Don't recommend controls that are unverifiable (must map to a checklist item).
  • Don't ignore identity/runtime attack surface in favor of only network-layer analysis.
