2. Core Architectural Principles
A. Software Bill of Materials (SBOM)
An SBOM is a formal, machine-readable inventory of software components, libraries, and modules required to build a software application (e.g., CycloneDX or SPDX formats).
B. Policy as Code (OPA - Open Policy Agent)
Allows defining security and compliance rules directly as code (.rego files) to block non-compliant Kubernetes manifests or Terraform code during CI/CD execution.
C. Vulnerability Threshold Gates
Configuring automated pipeline break rules based on CVSS Severity Scores (e.g., fail pipeline if CRITICAL or HIGH vulnerabilities are found).
