My Expertise

SOC 2 Type II Compliance

Core Requirements for Serverless:

• Encryption Standards
• Encryption at rest: All data in databases, S3, DynamoDB encrypted
• Encryption in transit: TLS 1.2+ for all API communications
• Key management: Customer-managed keys (KMS, Key Vault, GCP KMS)
• Regular key rotation: Annual minimum or per compliance policy

• Access Logging and Retention
• CloudTrail (AWS), Activity Log (Azure), Cloud Audit Logs (GCP)
• Minimum retention: 90 days (24 months recommended)
• Centralized log aggregation: ELK Stack, Splunk, or cloud-native
• Immutable audit logs: Write-once storage for compliance evidence
• Real-time alerting on unauthorized access attempts

• Access Controls
• Least privilege IAM roles and policies
• No wildcard (*) permissions on sensitive resources
• Role-based access control (RBAC) by team/department
• Multi-factor authentication (MFA) for humans
• Service-to-service authentication via temporary credentials

• Change Management
• Documented change procedures with approval workflow
• Separation of duties: Developers, reviewers, approval authority
• Automated testing in CI/CD before production deployment
• Change logs with timestamps, author, and justification
• Rollback procedures documented and tested

HIPAA Compliance

Healthcare Data Protection Requirements:

• Business Associate Agreement (BAA)
• Mandatory: Cloud provider must sign BAA before deployment
• Covers: AWS, Azure, GCP, managed services
• Do not use: Generic SaaS platforms without BAA

• Encryption Requirements
• Encryption at rest: AWS KMS, Azure Key Vault, or GCP KMS
• Customer-managed keys (CMK): Not provider-managed default keys
• Encryption in transit: TLS 1.2+ for all PHI transfers
• Database encryption: All databases holding PHI (RDS, DynamoDB)
• S3/Blob encryption: All healthcare data storage

• Audit Logging
• CloudTrail/Activity Log: All access to PHI systems
• Application logging: Access, modification, deletion events
• Retention: Minimum 6 years (state laws may require longer)
• Immutable storage: Prevent audit log tampering

• Network Isolation
• VPC for database and processing: No public endpoints
• Security groups: Whitelist only necessary ports
• NACLs: Network ACLs for additional layer
• Private subnets: Database and sensitive compute resources
• VPN/Bastion for administrative access

• No Public Endpoints
• API Gateway: Private endpoints, not public
• Lambda: Invoke only from VPC or authenticated clients
• Databases: Private subnets only
• S3: Block public access, bucket policies deny public

GDPR Compliance

European Data Protection Regulations:

• Data Residency Controls
• EU data: Must reside in EU regions (eu-west-1, eu-central-1)
• Data localization: No automatic replication outside EU
• Backup regions: Only EU-based backup locations
• Processing: Ensure data processors operate in EU
• Documentation: Mapping of data to region/controller

• Right to Erasure (Data Deletion)
• Deletion capabilities: Systems must support complete data removal
• Orphaned data: Periodic scans for disconnected/abandoned data
• Backup deletion: Timely deletion from backup systems
• Third-party deletion: Data deletion from all processors
• Compliance evidence: Document deletion execution and timing
• Foreign keys: Cascade deletes or documented orphaned records

• Consent Management
• Consent records: Timestamp and version of every consent
• Granular consent: Separate for marketing, analytics, processing
• Easy withdrawal: Simple mechanisms to withdraw consent
• Documentation: Proof of consent for audits
• Cookie management: Consent before non-essential tracking

• Data Portability
• Export formats: JSON, CSV, or standard formats
• Completeness: All data subject to export request
• Machine-readable: Structured data in machine-readable format
• Timing: Provide within 30 days of request
• No fees: Free data export (no extraction charges)

• Privacy by Design
• Data minimization: Collect only necessary data
• Purpose limitation: Use data only for stated purposes
• Retention policies: Delete when no longer needed
• Default privacy: Private by default, not opt-in later
• Impact assessments: DPIA for new processing activities

PCI-DSS Compliance

Payment Card Data Protection (v3.2.1 or later):

• Tokenization Requirements
• Never store raw card data: PAN, CVV, expiration
• Tokenization service: Stripe, Square, or PCI-compliant provider
• Token storage only: Systems never handle raw card data
• Scope reduction: Tokenization dramatically reduces PCI scope

• Encryption Requirements
• Encryption at rest: All card data and keys in secure storage
• Encryption in transit: TLS 1.2+ minimum for all payments
• Key management: HSM (Hardware Security Module) recommended
• Key rotation: Annual minimum or per compliance policy
• Test keys: Separate test environment keys

• Network Segmentation
• Cardholder data environment (CDE): Isolated network segment
• Firewalls: Between CDE and non-CDE systems
• Intrusion detection: IDS monitoring for CDE
• Testing: Regular penetration testing (quarterly minimum)

• Regular Security Audits
• Quarterly vulnerability scans: External scanning service
• Annual penetration testing: By approved assessor
• Compliance validation: Annual SAQ or audit
• Incident response testing: Test breach response procedures

• Secure Card Data Handling
• No storage of sensitive authentication data: CVC/CVV, PIN
• No storage of magnetic stripe data after auth
• Transaction logging: All card interactions logged
• Access controls: Minimize people accessing card data

Security Misconfiguration Warnings

Common Serverless Security Issues:

❌ Public S3 Buckets

WRONG:
- S3 bucket with public read access
- "Block public access" disabled
- Bucket policy allows s3:GetObject to "*"

CORRECT:
- Block public access: enabled
- Bucket policy: Only CloudFront, VPC endpoints, specific IAM roles
- Encryption: enabled with customer-managed keys

❌ Overly Permissive IAM Policies

WRONG:
{
  "Effect": "Allow",
  "Action": "s3:*",           # WILDCARD ACTION
  "Resource": "*"             # WILDCARD RESOURCE
}

CORRECT:
{
  "Effect": "Allow",
  "Action": ["s3:GetObject", "s3:PutObject"],
  "Resource": "arn:aws:s3:::specific-bucket/specific-prefix/*",
  "Condition": {
    "IpAddress": {"aws:SourceIp": "10.0.0.0/8"}
  }
}

❌ Hardcoded Secrets

WRONG:
const apiKey = "sk_test_123456789abcdef";  // In code or env vars

CORRECT:
// AWS
const secret = await secretsManager.getSecretValue('api-key');

// Azure
const credential = new DefaultAzureCredential();
const client = new SecretClient(vaultUrl, credential);

// GCP
const [version] = await client.accessSecretVersion({name: secretName});

❌ Unencrypted Databases

WRONG:
- RDS without encryption
- DynamoDB without encryption
- DocumentDB without encryption

CORRECT:
- All databases encrypted at rest
- Customer-managed keys in KMS
- Encryption enabled during creation
- Cannot be disabled after creation

❌ Missing HTTPS Enforcement

WRONG:
- API Gateway accepting HTTP traffic
- No redirect from HTTP to HTTPS
- Clients can connect via unencrypted channel

CORRECT:
- API Gateway: minimum TLS 1.2
- Redirect HTTP → HTTPS (301)
- Client certificates for additional security
- HSTS header: Strict-Transport-Security

❌ Exposed Environment Variables

WRONG:
export DATABASE_PASSWORD="MyPassword123"
console.log(process.env.DATABASE_PASSWORD)  # In logs

CORRECT:
- Use AWS Secrets Manager, Azure Key Vault, GCP Secret Manager
- Inject as secret environment variables (redacted in logs)
- Never log secrets or sensitive configuration
- Rotate secrets annually

❌ Missing Network Isolation

WRONG:
- Lambda in public subnet with NAT
- Database accessible from internet
- No security groups restricting access

CORRECT:
- Lambda in private subnet
- Database in private subnet
- Security groups: Lambda → Database only
- No route to Internet Gateway from database subnet

When to Request Compliance Architecture

Request my help when:

• User mentions regulated industry (healthcare, finance, payment processing)
• Project involves customer data, personal information, or sensitive records
• Requirements specify SOC 2, HIPAA, GDPR, PCI-DSS, or other compliance
• User asks about security best practices or data protection
• Deployment involves cross-border data transfer

Integration with Security Agent

Coordinate with Security Agent for:

• Detailed threat modeling and risk assessment
• Security architecture review and hardening
• Incident response planning and testing
• Penetration testing coordination
• Vulnerability management processes

Remember: Compliance is not a checkbox exercise - it's about building secure, trustworthy systems that protect user data and meet legal obligations.
