description	Create security architecture diagrams using PlantUML syntax with identity, encryption, firewall, and compliance stencil icons. Best for IAM flows, zero-trust architectures, encryption pipelines, compliance auditing, and threat detection. NOT for general cloud infra (use cloud skill) or simple flowcharts (use mermaid).

Security Architecture Diagram Generator

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.

Critical Rules

• 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)

Full stencil reference: See stencils/README.md for 9500+ available icons.

Mxgraph Stencil Syntax

mxgraph.aws4.<icon> "Label" as <alias>

Identity & Access Stencils

Category	Stencils	Purpose
IAM	identity_and_access_management, identity_access_management_iam_roles_anywhere	Identity policies & roles
SSO/Directory	cognito, ad_connector, directory_service, cloud_directory	User authentication & federation
STS	sts, sts_alternate	Temporary security credentials
Organizations	organizations, organizations_account, organizations_organizational_unit	Multi-account governance

Encryption & Secrets Stencils

Category	Stencils	Purpose
KMS	key_management_service, key_management_service_external_key_store	Key management & encryption
Secrets	secrets_manager	Secrets rotation & storage
Certificates	certificate_manager, private_certificate_authority	TLS certificate lifecycle
HSM	cloudhsm	Hardware security module
Encryption	encrypted_data	Encrypted data at rest

Network Security Stencils

Category	Stencils	Purpose
Firewall	network_firewall, network_firewall_endpoints, firewall_manager	Network traffic filtering
WAF	generic_firewall	Web application firewall
Shield	shield, shield_shield_advanced, shield2	DDoS protection
Security Group	security_group, group_security_group	Instance-level firewall

Threat Detection & Compliance Stencils

Category	Stencils	Purpose
Detection	guardduty, detective, inspector	Threat detection & investigation
Data Protection	macie	Sensitive data discovery
Compliance	security_hub, security_hub_finding, audit_manager, config	Compliance posture & audit
Logging	cloudtrail, cloudtrail_cloudtrail_lake, security_lake	Audit trail & log aggregation
Governance	control_tower, organizations	Multi-account governance
Incident	security_incident_response	Incident management

Connection Types

Syntax	Meaning	Use Case
A --> B	Solid arrow	Auth flow / access request
A ..> B	Dashed arrow	Audit event / async detection
A -- B	Solid line	Trust relationship
A --> B : "label"	Labeled connection	Describe protocol or credential

Quick Example

@startuml
left to right direction
mxgraph.aws4.users "Users" as users
mxgraph.aws4.cognito "Cognito" as auth
mxgraph.aws4.identity_and_access_management "IAM" as iam

rectangle "Protected Resources" {
  mxgraph.aws4.s3 "Data (S3)" as s3
  mxgraph.aws4.encrypted_data "Encrypted" as enc
}

users --> auth : "login"
auth --> iam : "token"
iam --> s3
s3 --> enc
@enduml
