1. Identity as the New Security Perimeter
Every API endpoint and internal service communication requires cryptographically signed JWT tokens and mutual TLS (mTLS) authentication. No service is trusted simply because it resides inside the virtual private cloud (VPC).
mTLS Service-to-Service Encryption: Istio service meshes manage automated certificate rotation every 24 hours.
Just-In-Time (JIT) Privileges: Engineers access production environments exclusively through time-limited, approved jump-hosts.
Immutable Audit Logs: CloudTrail and VPC flow logs are mirrored in real-time to write-once-read-many (WORM) S3 buckets.
