1. Data Encryption & Key Management
All persistent storage volumes and MongoDB databases utilize AES-256 block-level encryption. Encryption keys are managed with automatic rotation policies and strict access control list (ACL) separation. All network transmissions require TLS 1.3 with HSTS enabled.
2. Network & Infrastructure Isolation
Production microservices execute in private VPC subnets with ingress firewalls. Direct public SSH/database access is disabled; all administrative operations require cryptographic bastion authentication with time-limited certificates.
3. Continuous Vulnerability Management
Every code commit triggers automated Static Application Security Testing (SAST) and software composition analysis (SCA) for dependency vulnerabilities. Weekly container vulnerability scans ensure third-party base images remain patched.
4. Incident Response & Disaster Recovery
Automated hourly encrypted snapshot backups are replicated to geo-redundant storage regions. Recovery Point Objective (RPO) is strictly under 15 minutes, with a Recovery Time Objective (RTO) under 60 minutes for tier-1 clinical clusters.
