Security Baseline

Threat Model (High Level)

• Primary users: [internal / external]
• Assets to protect:
  • [e.g., customer PII, payment data, secrets]
• Primary threats:
  • [e.g., unauthorized access, data exfiltration, data tampering]

Required Controls

Authentication

• Use [e.g., OAuth2 / OIDC / SSO] for user identity.
• Never build custom password handling if avoidable.

Authorization

• Enforce least privilege.
• Centralize authorization decisions when possible.

Input Validation & Output Encoding

• Validate all untrusted input at boundaries.
• Sanitize or encode output where appropriate (HTML, JSON, SQL, etc.).

Secrets Management

• Store secrets in [vault / secret manager], never in code or config files.
• Rotate secrets according to policy.

Logging & Auditing

• Log security-relevant events:
  • Logins, permission changes, critical operations.
• Avoid logging sensitive data.

Common Vulnerabilities

See vulnerabilities.md for patterns to search for and avoid.

Security Testing Requirements

See security-testing.md for:

• Required automated checks
• Manual review steps for critical flows
