# Table of Contents - Container Security Policy and Implementation Standard

## Executive Overview
*A comprehensive guide to implementing enterprise-grade container security across Docker, ECR, ECS, and EKS while maintaining PCI DSS, HIPAA, and SOC 2 compliance.*

---

## 📋 Core Policy Framework

### [1. Executive Summary and Purpose](#1-executive-summary-and-purpose)
Establishes the policy objectives, scope boundaries, and risk tolerance principles. Defines the zero-trust, fail-secure approach and sets severity-based response timelines for security findings across development, staging, and production environments.

### [2. Data Classification Scheme](#2-data-classification-scheme)
Creates four-tier classification system (Restricted/Confidential/Internal/Public) with specific container requirements for each level. Essential for HIPAA PHI and PCI DSS cardholder data protection requirements.

### [3. Governance and Ownership](#3-governance-and-ownership)
Defines RACI matrix for security responsibilities, SLA requirements by severity (24hr for Critical to 30d for Low), and formal exception management process with compensating controls and approval workflows.

### [4. Tool Stack Architecture](#4-tool-stack-architecture)
Complete security toolchain recommendation with open-source focus: Trunk.io for pre-commit, Trivy/Grype for scanning, Cosign for signing, OPA Gatekeeper for policy, Falco for runtime, and native AWS services. Includes cost analysis and integration architecture.

---

## 🔧 Technical Implementation

### [5. Shift-Left Security Controls](#5-shift-left-security-controls)
Developer workstation configurations with Trunk.io, comprehensive CI/CD pipeline templates for both Harness and GitHub Actions, including secret scanning, SAST, container scanning, SBOM generation, and image signing workflows.

### [6. Image Standards and Hardening](#6-image-standards-and-hardening)
Approved base image catalog with size limits, secure Dockerfile templates demonstrating multi-stage builds, non-root execution, and minimal attack surface. Includes detailed hardening checklist for runtime security contexts.

### [7. Registry Security (Amazon ECR)](#7-registry-security-amazon-ecr)
Complete ECR configuration with Terraform code for immutable tags, KMS encryption, lifecycle policies, cross-account access, and VPC endpoints. Harbor setup for external registry proxy with vulnerability scanning.

### [8. Kubernetes (EKS) Security Configuration](#8-kubernetes-eks-security-configuration)
Production-ready EKS cluster configuration, OPA Gatekeeper policy templates (non-root, no-privileged, signed-images, resource-limits), Calico network policies for zero-trust networking, and comprehensive RBAC with namespace isolation.

---

## 🛡️ Runtime and Operations

### [9. Runtime Security](#9-runtime-security)
Falco rules for detecting container escapes, cryptocurrency mining, and sensitive data access. AWS GuardDuty EKS integration with automated response via Lambda functions and EventBridge rules.

### [10. Secrets Management](#10-secrets-management)
AWS Secrets Manager integration with automatic rotation, External Secrets Operator for Kubernetes, Sealed Secrets for static configs, and Python Lambda functions for secret rotation orchestration.

### [11. Logging, Monitoring, and Detection](#11-logging-monitoring-and-detection)
Fluent Bit configuration for centralized logging with PII redaction, Prometheus metrics and alerting rules for security events, real-time detection of unsigned images and root containers.

### [12. AWS Security Hub Integration](#12-aws-security-hub-integration)
Lambda-based integration for consolidating findings from all security tools, custom Security Hub insights for container-specific threats, automated Jira ticket creation and Slack notifications for high-severity findings.

---

## 🚨 Incident Response and Compliance

### [13. Incident Response](#13-incident-response)
Automated container compromise playbook with immediate isolation, evidence collection, forensic analysis steps. Includes forensics container Dockerfile and YARA rules for malware detection.

### [14. Compliance Mapping](#14-compliance-mapping)
Detailed control mapping matrix showing how each security control satisfies specific PCI DSS, HIPAA, and SOC 2 requirements. Critical for audit preparation and evidence collection.

### [15. Metrics and KPIs](#15-metrics-and-kpis)
Python scripts for calculating MTTR, image signing percentage, SBOM coverage, and vulnerability metrics. Grafana dashboard configurations for real-time security posture visibility.

## 📅 Implementation Guide

### [16. 90-Day Implementation Roadmap](#16-90-day-implementation-roadmap)
**Phase 1 (Days 1-30):** Foundation - ECR setup, basic scanning, exception process  
**Phase 2 (Days 31-60):** Orchestration - EKS deployment, network policies, runtime monitoring  
**Phase 3 (Days 61-90):** Advanced - Secrets rotation, compliance validation, team training  
Includes quick wins for Week 1 and specific success metrics for each phase.

### [17. Appendix: Tool Installation Scripts](#17-appendix-tool-installation-scripts)
Ready-to-run bash scripts for installing entire security stack, configuring Git hooks, and setting up development environments. Designed for rapid deployment across your engineering team.
