[APIPOSTURE SYSTEM CONSOLE // DEVOPS AUDIT MATRIX] • TARGET: OWASP API Core Infrastructure Verification | STATUS: ACTION REQUIRED
1. Edge Perimeter & API Gateway Validation (BOLA Control)
This boundary handles initial cryptographic token termination and maps claims directly to upstream request routing patterns at the perimeter.
[ ] Token-to-Upstream Header Injection: Configure the API Gateway to validate incoming JWTs and strictly map the token-derived tenant identifier into immutable upstream headers like X-Tenant-ID to satisfy SOC 2 CC6.1.
[ ] Path-to-Claim Verification Routing: Deploy declarative regex policies at the proxy block to automatically drop requests when a resource URL parameter conflicts with the tenant ID embedded in the caller's cryptographic token payload.
2. Ingress Schema Validation Filters (Mass Assignment Control)
This boundary operates at the cluster ingress layer, inspecting request bodies against strict structural validation rules before hit-testing web application instances.
[ ] OpenAPI Validation Engine Deployment: Enable the OpenAPI validation module within your Kubernetes Ingress controller to dynamically intercept mutations and drop arbitrary payloads that do not strictly conform to expected models.
[ ] Undeclared Object Field Dropping: Enforce strict reject-extra-fields configuration parameters on incoming JSON streams to block unauthorized parameters like is_admin or role_id from ever passing through the proxy layer into backend systems to align with ISO 27001 A.14.2.5.
3. Network Mesh Isolation Rules (SSRF Control)
This boundary controls outbound lateral movement and sets egress connectivity boundaries for container workloads generating third-party webhook requests.
[ ] Registry-Only Mesh Outbound Configuration: Set your Service Mesh outbound traffic policy mode to REGISTRY_ONLY, guaranteeing that application containers cannot route sockets to destinations not explicitly safelisted in declarative manifest setups.
[ ] Cloud Metadata Endpoint Shunting: Apply strict Kubernetes NetworkPolicies across API worker pods that drop traffic hitting link-local space (169.254.169.254) and internal RFC 1918 subnets, establishing compliant segmentation boundaries to align with HIPAA §164.312(e)(1).
4. Pipeline Verification Rules (CI/CD Deployment Gates)
This boundary acts as an automated governance engine integrated into code review systems to audit infrastructure configurations prior to merge events.
[ ] Declarative Open-Source Linting: Embed validation engines into GitHub Actions or GitLab CI workflows that scan OpenAPI schemas for unauthenticated data paths or missing property restrictions before authorizing pull requests to merge.
[ ] Branch Enforcement Security Policy: Lock production repository branches behind passing compliance pipelines, producing cryptographically signed metadata build artifacts required for SOC 2 TSC CC6.3 evidence collections.
5. Centralized Observability & Egress Routing (Security Logging)
This boundary structures runtime execution metrics and routes authorization log signals down to unalterable monitoring fabrics.
[ ] Structured Authorization Event Routing: Configure edge log agents (e.g., FluentBit, OpenTelemetry Collector) to flag, convert, and forward schema mismatches or BOLA validation errors instantly into unified JSON formats.
[ ] Hardened SIEM Audit Streaming: Stream filtered infrastructure security alerts to a secure write-once, read-many SIEM aggregator over TLS to achieve unalterable, non-repudiable auditing matching ISO 27001 A.12.4.1 patterns.
