Architecture Overview
Four-layer security architecture: perimeter (network controls), application (AI safety layer), data (DLP and encryption), and identity (access management). Each layer provides defense-in-depth with independent controls.
Network Layer Design
Implement: TLS 1.3 termination at load balancer, Web Application Firewall (WAF) rules for AI traffic, private endpoints for on-premises integration, egress filtering to approved AI providers only, and DDoS protection.
Application Layer Design
Deploy AI safety layer with: input validation pipeline (rule-based → semantic analysis), output screening pipeline (content safety → brand safety), rate limiting engine, session management, and comprehensive request/response logging.
Identity Layer Design
Implement: SAML 2.0/OIDC for SSO, MFA enforcement via identity provider, three-tier RBAC (admin → department head → user), JWT-based session management, API key governance with rotation policies, and automated provisioning/deprovisioning.
