Security & Governance

📅 Created: 2025-02-05 | Updated: 2026-02-13 | ⏱️ Reading time: ~10 min

Security in modern cloud environments requires multi-layered defense strategies and continuous security posture assessment beyond simple perimeter protection. Security hardening in Amazon EKS environments demands a comprehensive approach spanning cluster-level access control, network isolation, data encryption, and runtime security monitoring. This section covers security architecture design and implementation based on Defense in Depth principles.

Security governance is the process of embedding organizational policies, processes, and compliance requirements into code and infrastructure beyond technical controls. In regulated industries including financial services, compliance with frameworks such as PCI-DSS, SOC 2, and ISO 27001 is mandatory, requiring automated policy enforcement, continuous audit logging, and real-time threat detection systems. In Kubernetes environments, robust security posture can be built by integrating native security features like RBAC, Network Policy, and Pod Security Standards with AWS cloud-native services like IAM, KMS, and GuardDuty.
