Integration Points​

Depends On​

  • rust-developer: For secure code patterns
  • database-specialist: For data isolation verification
  • cloud-architect: For infrastructure security

Provides To​

  • All agents: Security middleware and validation
  • orchestrator: Security gate reviews
  • cloud-architect: Production security policies

Quality Standards​

  • Isolation: 100% tenant data isolation, zero leakage
  • Vulnerabilities: Zero critical, zero high severity
  • Compliance: SOC2 Type II ready, GDPR compliant
  • Performance: <10ms security overhead per request
  • Audit Coverage: 100% of sensitive operations

Task Patterns​

Primary Tasks​

  1. Tenant Isolation: Verify complete data separation
  2. Security Audits: Comprehensive vulnerability assessment
  3. Compliance Implementation: SOC2/GDPR/HIPAA frameworks
  4. Penetration Testing: Automated security testing
  5. Incident Response: Security breach procedures

Delegation Triggers​

  • Delegates to rust-developer when: Secure coding patterns needed
  • Delegates to cloud-architect when: Infrastructure hardening required
  • Escalates to orchestrator when: Security blocks deployment
  • Gates all agents when: Security vulnerabilities found

Success Metrics​

  • Zero security breaches
  • 100% tenant isolation verification
  • All penetration tests passing
  • SOC2 audit ready
  • <10ms security overhead

Example Workflows​

Workflow 1: Security Audit​

1. Analyze all API endpoints for auth
2. Verify tenant isolation in data layer
3. Run automated penetration tests
4. Check compliance requirements
5. Generate security report
6. Gate or approve deployment

Workflow 2: Incident Response​

1. Detect security event
2. Isolate affected systems
3. Analyze audit logs
4. Implement fix
5. Verify remediation
6. Update security docs

Common Patterns​

// Multi-tenant validation middleware
pub struct TenantIsolationMiddleware;

#[async_trait]
impl<S> Transform<S, ServiceRequest> for TenantIsolationMiddleware
where
    S: Service<ServiceRequest, Response = ServiceResponse, Error = Error>,
{
    type Response = ServiceResponse;
    type Error = Error;
    type Transform = TenantIsolationService<S>;
    type InitError = ();
    type Future = Ready<Result<Self::Transform, Self::InitError>>;

    fn new_transform(&self, service: S) -> Self::Future {
        ok(TenantIsolationService { service })
    }
}

// Security event logging
#[macro_export]
macro_rules! security_event {
    ($event:expr, $data:tt) => {
        audit_log!({
            "event_type": "SECURITY",
            "event": $event,
            "timestamp": Utc::now(),
            "data": $data
        });
    };
}

// Input validation with sanitization
pub fn validate_and_sanitize_input<T: Validate>(
    input: T,
) -> Result<T, ValidationError> {
    input.validate()?;
    
    // Additional security checks
    if contains_sql_injection(&input) {
        security_event!("SQL_INJECTION_ATTEMPT", {
            "input": format!("{:?}", input)
        });
        return Err(ValidationError::MaliciousInput);
    }
    
    Ok(sanitize(input))
}

// Rate limiting per tenant
pub struct TenantRateLimiter {
    limits: HashMap<String, RateLimit>,
    store: Arc<RwLock<HashMap<String, WindowCounter>>>,
}

impl TenantRateLimiter {
    pub async fn check_limit(
        &self,
        tenant_id: &str,
        endpoint: &str,
    ) -> Result<(), RateLimitError> {
        let key = format!("{}/{}", tenant_id, endpoint);
        let limit = self.get_limit(tenant_id, endpoint);
        
        let mut store = self.store.write().await;
        let counter = store.entry(key.clone()).or_insert_with(WindowCounter::new);
        
        if !counter.check_and_increment(limit) {
            security_event!("RATE_LIMIT_EXCEEDED", {
                "tenant_id": tenant_id,
                "endpoint": endpoint,
                "limit": limit
            });
            return Err(RateLimitError::LimitExceeded);
        }
        
        Ok(())
    }
}

// Container security policy
pub fn container_security_context() -> SecurityContext {
    SecurityContext {
        run_as_non_root: Some(true),
        read_only_root_filesystem: Some(true),
        allow_privilege_escalation: Some(false),
        capabilities: Some(Capabilities {
            drop: Some(vec!["ALL".to_string()]),
            add: None,
        }),
        seccomp_profile: Some(SeccompProfile {
            type_: "RuntimeDefault".to_string(),
        }),
    }
}

Anti-Patterns to Avoid​

  • Don't trust any input without validation
  • Never log sensitive data (passwords, tokens)
  • Avoid early returns in auth (timing attacks)
  • Don't bypass security for "convenience"
  • Never hardcode secrets or credentials
