[APIPOSTURE SYSTEM CONSOLE // DEVOPS AUDIT MATRIX] • TARGET: REST API AUTHENTICATION & IDENTITY CONTROLS | STATUS: ACTION REQUIRED
1. Token Hardening & Cryptographic Validation
Enforce strict cryptographic signature verification and tight token lifetimes at the API gateway layer.
[ ] Asymmetric Algorithm Enforcement: Configure the identity proxy to explicitly reject symmetric HS256 tokens and strictly require asymmetric RS256/ES256 algorithms verified against an internal JWKS endpoint.
[ ] Ephemeral Token Lifetimes: Set the absolute maximum Time-To-Live (TTL) for stateless access tokens to less than 15 minutes within the authorization server policy engine.
[ ] Distributed Revocation Backends: Deploy a high-availability Redis cache layer at the gateway level to instantly validate incoming JTI tokens against a real-time global revocation blacklist.
2. OAuth 2.0 & OIDC Authorization Controls
Secure authorization grant workflows, client interactions, and fine-grained scope policies.
[ ] PKCE Extension Mandate: Enforce Proof Key for Code Exchange (PKCE) inside the identity provider configurations for all public clients, mobile applications, and Single Page Applications (SPAs).
[ ] Scope & Claim Boundary Validation: Implement centralized ingress filters that explicitly validate OAuth scopes and standard claims before routing traffic to prevent Broken Function Level Authorization (BFLA).
[ ] Redirect URI Strict Whitelisting: Configure the authorization server to enforce absolute string matching against explicit redirect URL whitelists, blocking partial path wildcards.
3. Transport Layer Protection & Service Mesh Identity
Lock down east-west network paths and external ingress connections with zero-trust cryptographic requirements.
[ ] Service-to-Service mTLS: Deploy a service mesh or ingress controller policy that mandates Mutual TLS (mTLS) with cryptographically verified SAN parameters for all east-west microservice traffic.
[ ] TLS Cipher Suite Hardening: Disable TLS 1.0 and 1.1 across all load balancers, enforcing TLS 1.2 minimum profiles utilizing only secure, forward-secret cipher suites (ECDHE-ECDSA/RSA).
4. Infrastructure Credential Separation & Secret Isolation
Isolate sensitive administrative credentials and infrastructure secrets away from flat source code or runtime environments.
[ ] Static Config Elimination: Audit IaC templates and Git configurations using automated scanner plugins to ensure no hardcoded provider keys, private salts, or database credentials exist.
[ ] Dynamic Secret Injection: Enforce runtime injection of API keys and database tokens directly into containers using an ephemeral KMS provider or external secrets manager.
[ ] Automated Secret Rotation: Establish an automated lifecycle rule within the cloud secrets repository to rotate infrastructure access credentials and internal API service keys every 90 days.
