security

Quick Start: Define trust boundaries → Place identity/encryption/firewall icons → Connect with access flows → Group into security zones → Wrap in ```plantuml fence. ⚠️ IMPORTANT: Always use ```plantuml or ```puml code fence. NEVER use ```text — it will NOT render as a diagram. Full stencil reference: See stencils/README.md for 9500+ available icons. - Every diagram starts with @startuml and ends with @enduml - Use left to right direction for access flows (User → AuthN → AuthZ → Resource) - Use mxgraph.aws4.* stencil syntax for security service icons - Default colors are applied automatically — you do NOT need to specify fillColor or strokeColor - Use rectangle "Trust Boundary" { ... } for security zones - Directed flows use --> , audit/async flows use ..> (dashed)
