STRIDE Threat Model
For each system component, evaluate:
| Threat | Question | Example Control |
|---|---|---|
| Spoofing | Can an attacker impersonate a user or service? | MFA, certificate pinning |
| Tampering | Can data be modified in transit or at rest? | HMAC, TLS, signing |
| Repudiation | Can users deny taking an action? | Audit logging, non-repudiation |
| Information Disclosure | Can secrets or data leak? | Encryption, least privilege |
| Denial of Service | Can attackers make service unavailable? | Rate limiting, CDN, auto-scaling |
| Elevation of Privilege | Can attackers gain higher permissions? | RBAC, input validation, sandboxing |
OWASP Top 10 Checklist
- Broken Access Control — verify authz checks on every route, not just UI
- Cryptographic Failures — no MD5/SHA1 for passwords; use bcrypt/Argon2
- Injection — parameterized queries only; never string-concatenate SQL
- Insecure Design — threat model before building, not after
- Security Misconfiguration — disable debug in prod, remove default accounts
- Vulnerable Components —
npm audit,pip-audit, Dependabot alerts - Auth Failures — rate limit login, secure session management, httpOnly cookies
- Integrity Failures — verify signatures on CI/CD artifacts and dependencies
- Logging Failures — log all auth events, failures, and admin actions
- SSRF — validate and allowlist all URLs used in server-side requests
Incident Response Playbook
Containment Steps (first 30 minutes)
- Isolate affected systems (network segment or shutdown)
- Preserve evidence: memory dump, disk image, logs
- Revoke compromised credentials immediately
- Notify security lead and legal (for breach reporting obligations)
- Open incident ticket with severity, timeline, and initial indicators
Severity Classification
- P1: Active breach, data exfiltration confirmed or likely
- P2: Suspected breach, unusual access patterns detected
- P3: Vulnerability confirmed but no active exploitation
- P4: Security misconfiguration with no immediate risk
SOC2 Type II Controls (Key Trust Services Criteria)
- CC6.1: Logical access controls (MFA, least privilege, access reviews)
- CC6.7: Data transmission encryption
- CC7.2: System monitoring and anomaly detection
- CC9.2: Risk assessment process documented and executed annually
- A1.2: Availability monitoring with SLA targets defined
