Beyond the Castle-and-Moat Defense
In distributed multi-cloud architectures, the internal network cannot be trusted by default. Every incoming request, service-to-service communication, and database transaction must be explicitly authenticated, authorized, and encrypted.
Pillars of Zero-Trust Engineering
•Ephemeral Access Tokens: Limit token lifespans to minutes, backed by cryptographically signed JWTs with rotating public key sets (JWKS).
•Mutual TLS (mTLS): Enforce bidirectional certificate validation across internal services to stop man-in-the-middle exploits.
•Automated Dependency Auditing: Continuous container and package scanning integrated into the CI/CD pipeline.
