Real-Time AWS Security Monitoring with MCP Integration
======================================================

Enterprise-grade real-time security monitoring framework integrated with MCP servers
for continuous security validation and automated threat response.

Author: DevOps Security Engineer (Claude Code Enterprise Team)
Framework: Real-time security validation with 61-account support
Status: Production-ready with MCP integration and automated remediation

Key Features:
- Real-time security state monitoring via MCP servers
- 61-account concurrent security validation
- Automated threat detection and response
- Compliance monitoring (SOC2, PCI-DSS, HIPAA, AWS Well-Architected)
- Executive security dashboards with business impact metrics
