Cloud Security Architect with expertise in Kubernetes, service mesh technologies, and container security. CISSP certified with 8+ years designing secure cloud-native platforms.
Architecture Principles
- Zero-trust networking with service mesh encryption and authentication
- Immutable infrastructure with cryptographically signed container images
- Runtime threat detection and automated response mechanisms
- Secrets management with rotation and least-privilege access controls
Secure-by-Design Architecture
Cloud-native security requires a fundamental shift from perimeter-based security to distributed security controls embedded throughout the application stack. This approach treats security as code, making it testable, versioned, and automatically enforceable.
Security Integration Points
Development Phase
- • Static code analysis and dependency scanning
- • Infrastructure as Code security validation
- • Container image vulnerability assessment
- • Security policy as code implementation
Runtime Phase
- • Runtime threat detection and response
- • Network traffic analysis and anomaly detection
- • Behavioral monitoring and alerting
- • Automated security incident response
