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:

1. •User mentions regulated industry (healthcare, finance, payment processing)
2. •Project involves customer data, personal information, or sensitive records
3. •Requirements specify SOC 2, HIPAA, GDPR, PCI-DSS, or other compliance
4. •User asks about security best practices or data protection
5. •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.

Project-Specific Learnings

Before starting work, check for project-specific learnings:

# Check if skill memory exists for this skill
cat .specweave/skill-memories/compliance-architecture.md 2>/dev/null || echo "No project learnings yet"

Project learnings are automatically captured by the reflection system when corrections or patterns are identified during development. These learnings help you understand project-specific conventions and past decisions.
