+# Security Policy
+
+## Overview
+
+WHOOSH implements enterprise-grade security controls to protect against common web application vulnerabilities and ensure safe operation in production environments. This document outlines our security implementation, best practices, and procedures.
+
+## 🔐 Security Implementation
+
+### Authentication & Authorization
+
+**JWT Authentication**
+- Role-based access control (admin/user roles)
+- Configurable token expiration (default: 24 hours)
+- Support for file-based and environment-based secrets
+- Secure token validation with comprehensive error handling
+
+**Service Token Authentication**
+- Internal service-to-service authentication
+- Scoped permissions for automated systems
+- Support for multiple service tokens
+- Configurable token management
+
+**Protected Endpoints**
+All administrative endpoints require proper authentication:
+- Council management (`/api/v1/councils/*/artifacts`)
+- Repository operations (`/api/v1/repositories/*`)
+- Team management (`/api/v1/teams/*`)
+- Task ingestion (`/api/v1/tasks/ingest`)
+- Project operations (`/api/v1/projects/*`)
+
+### Input Validation & Sanitization
+
+**Comprehensive Input Validation**
+- Regex-based validation for all input types
+- Request body size limits (1MB default, 10MB for webhooks)
+- UUID validation for all identifiers
+- Safe character restrictions for names and titles
+
+**Validation Rules**
+```go
+Project Names:    ^[a-zA-Z0-9\s\-_]+$           (max 100 chars)
+Git URLs:         Proper URL format validation
+Task Titles:      Safe characters only           (max 200 chars)
+Agent IDs:        ^[a-zA-Z0-9\-]+$             (max 50 chars)
+UUIDs:           RFC 4122 compliant format
+```
+
+**Injection Prevention**
+- SQL injection prevention through parameterized queries
+- XSS prevention through input sanitization
+- Command injection prevention through input validation
+- Path traversal prevention through path sanitization
+
+### CORS Configuration
+
+**Production-Safe CORS**
+- No wildcard origins in production
+- Configurable allowed origins via environment variables
+- Support for file-based origin configuration
+- Restricted allowed headers and methods
+
+**Configuration Example**
+```bash
+# Production CORS configuration
+WHOOSH_CORS_ALLOWED_ORIGINS=https://app.company.com,https://admin.company.com
+WHOOSH_CORS_ALLOWED_METHODS=GET,POST,PUT,DELETE,OPTIONS
+WHOOSH_CORS_ALLOWED_HEADERS=Authorization,Content-Type,X-Requested-With
+WHOOSH_CORS_ALLOW_CREDENTIALS=true
+```
+
+### Rate Limiting
+
+**Per-IP Rate Limiting**
+- Default: 100 requests per minute per IP address
+- Configurable limits and time windows
+- Automatic cleanup to prevent memory leaks
+- Support for proxy headers (X-Forwarded-For, X-Real-IP)
+
+**Configuration**
+```bash
+WHOOSH_RATE_LIMIT_ENABLED=true
+WHOOSH_RATE_LIMIT_REQUESTS=100        # Requests per window
+WHOOSH_RATE_LIMIT_WINDOW=60s          # Rate limiting window
+WHOOSH_RATE_LIMIT_CLEANUP_INTERVAL=300s  # Cleanup frequency
+```
+
+### Security Headers
+
+**HTTP Security Headers**
+```
+Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'
+X-Frame-Options: DENY
+X-Content-Type-Options: nosniff
+X-XSS-Protection: 1; mode=block
+Referrer-Policy: strict-origin-when-cross-origin
+```
+
+### Webhook Security
+
+**Gitea Webhook Protection**
+- HMAC SHA-256 signature validation
+- Timing-safe signature comparison using `hmac.Equal`
+- Request body size limits (10MB maximum)
+- Content-Type header validation
+- Comprehensive attack attempt logging
+
+**Configuration**
+```bash
+WHOOSH_WEBHOOK_SECRET_FILE=/run/secrets/webhook_secret
+WHOOSH_MAX_WEBHOOK_SIZE=10485760  # 10MB
+```
+
+## 🛡️ Security Best Practices
+
+### Production Deployment
+
+**Secret Management**
+```bash
+# Use file-based secrets in production
+WHOOSH_JWT_SECRET_FILE=/run/secrets/jwt_secret
+WHOOSH_GITEA_TOKEN_FILE=/run/secrets/gitea_token
+WHOOSH_WEBHOOK_SECRET_FILE=/run/secrets/webhook_secret
+
+# Docker Swarm secrets example
+echo "strong-jwt-secret-32-chars-min" | docker secret create whoosh_jwt_secret -
+```
+
+**Database Security**
+```bash
+# Use SSL/TLS for database connections
+WHOOSH_DATABASE_URL=postgres://user:pass@host/db?sslmode=require
+
+# Connection pool limits
+WHOOSH_DB_MAX_OPEN_CONNS=25
+WHOOSH_DB_MAX_IDLE_CONNS=10
+WHOOSH_DB_CONN_MAX_LIFETIME=300s
+```
+
+**TLS Configuration**
+```bash
+# Enable TLS in production
+WHOOSH_TLS_ENABLED=true
+WHOOSH_TLS_CERT_FILE=/path/to/cert.pem
+WHOOSH_TLS_KEY_FILE=/path/to/key.pem
+WHOOSH_TLS_MIN_VERSION=1.2
+```
+
+### Security Monitoring
+
+**Logging & Monitoring**
+- Structured logging with security event correlation
+- Failed authentication attempt monitoring
+- Rate limit violation alerting
+- Administrative action audit logging
+
+**Health & Security Endpoints**
+- `/health` - Basic health check (unauthenticated)
+- `/admin/health/details` - Detailed system status (authenticated)
+- `/metrics` - Prometheus metrics (unauthenticated)
+
+### Access Control
+
+**Role-Based Permissions**
+- **Admin Role**: Full system access, administrative operations
+- **User Role**: Read-only access to public endpoints
+- **Service Tokens**: Scoped access for internal services
+
+**Endpoint Protection Matrix**
+| Endpoint Category | Authentication | Authorization |
+|-------------------|---------------|---------------|
+| Public Health     | None          | None          |
+| Public APIs       | JWT           | User/Admin    |
+| Admin Operations  | JWT           | Admin Only    |
+| Internal Services | Service Token | Scoped Access |
+| Webhooks          | HMAC          | Signature     |
+
+## 🔍 Security Testing
+
+### Vulnerability Assessment
+
+**Regular Security Audits**
+- OWASP Top 10 compliance verification
+- Dependency vulnerability scanning
+- Static code analysis with security focus
+- Penetration testing of critical endpoints
+
+**Automated Security Testing**
+```bash
+# Static security analysis
+go run honnef.co/go/tools/cmd/staticcheck ./...
+
+# Dependency vulnerability scanning
+go mod tidy && go list -json -deps | audit
+
+# Security linting
+golangci-lint run --enable gosec
+```
+
+### Security Validation
+
+**Authentication Testing**
+- Token validation bypass attempts
+- Role escalation prevention verification
+- Session management security testing
+- Service token scope validation
+
+**Input Validation Testing**
+- SQL injection attempt testing
+- XSS payload validation testing
+- Command injection prevention testing
+- File upload security testing (if applicable)
