Security

​

Security Architecture

​

Zero-Trust Model

​

Authentication & Authorization

​

Multi-Factor Authentication

• SAML 2.0: Enterprise SSO integration
• OIDC: OpenID Connect support
• LDAP/AD: Active Directory integration
• Local Auth: Built-in user management
• MFA: Time-based OTP and hardware tokens

​

Role-Based Access Control (RBAC)

• Granular Permissions: Fine-grained access controls
• Resource-Level Security: Per-resource access policies
• Attribute-Based Access: Dynamic access based on attributes
• Audit Trail: Comprehensive access logging

​

Data Protection

​

Encryption

• At Rest: AES-256 encryption for all stored data
• In Transit: TLS 1.3 for all network communication (see SSL Certificate Management)
• Key Management: AWS KMS with automatic key rotation
• Database: Transparent data encryption (TDE)

​

Data Classification

• Sensitive Data: PII and confidential information protection
• Data Loss Prevention: Automated data classification and protection
• Retention Policies: Automated data lifecycle management
• Geographic Restrictions: Data residency compliance

​

Network Security

​

Perimeter Defense

• Web Application Firewall (WAF): OWASP Top 10 protection with AWS Managed Rules
• WAF IP Allowlisting: Application-level IPv4/IPv6 CIDR allowlisting with CloudWatch metrics and audit trails
• DDoS Protection: AWS Shield Advanced integration
• Security Groups: Network-level IP restrictions at the load balancer
• Rate Limiting: API rate limiting and throttling

​

WAF IP Allowlisting (ECS Deployments)

# Enable WAF IP allowlisting
waf_enable_ip_allowlisting = true
waf_allowlist_ipv4_cidrs = [
  "203.0.113.0/24",      # Office network
  "198.51.100.42/32",    # VPN gateway
]
waf_allowlist_ipv6_cidrs = [
  "2001:db8::/48",       # Office IPv6 range
]

• Audit Trail: All blocked requests logged to CloudWatch
• Metrics: Real-time metrics for security monitoring (alb-{project}-{environment}-allowlist)
• Compliance: Detailed request sampling for compliance requirements
• Priority Enforcement: Blocks non-allowlisted traffic before other WAF rules execute

​

Network Segmentation

• VPC Isolation: Private network with controlled access
• Security Groups: Stateful firewall rules
• NACLs: Network-level access controls
• Private Subnets: Database and application isolation

​

Compliance & Governance

​

Regulatory Compliance

• SOC 2 Type II: Security and availability controls
• GDPR: Data privacy and protection compliance
• HIPAA: Healthcare data protection (available)
• PCI DSS: Payment card industry compliance (available)

​

Security Monitoring

• SIEM Integration: Security information and event management
• Threat Detection: Automated threat detection and response
• Vulnerability Scanning: Regular security assessments
• Penetration Testing: Periodic security testing
