## Overview

Cloud security requires comprehensive strategies spanning identity management, encryption, network controls, compliance, and threat detection. Implement defense-in-depth with multiple layers of protection and continuous monitoring.

## When to Use

- Protecting sensitive data in cloud
- Compliance with regulations (GDPR, HIPAA, PCI-DSS)
- Implementing zero-trust security
- Securing multi-cloud environments
- Threat detection and response
- Identity and access management
- Network isolation and segmentation
- Encryption and key management

## Quick Start

Minimal working example:

```bash
# Enable GuardDuty (threat detection)
aws guardduty create-detector \
  --enable \
  --finding-publishing-frequency FIFTEEN_MINUTES

# Enable CloudTrail (audit logging)
aws cloudtrail create-trail \
  --name organization-trail \
  --s3-bucket-name audit-bucket \
  --is-multi-region-trail

# Enable S3 bucket encryption by default
aws s3api put-bucket-encryption \
  --bucket my-bucket \
  --server-side-encryption-configuration '{
    "Rules": [{
      "ApplyServerSideEncryptionByDefault": {
        "SSEAlgorithm": "aws:kms",
        "KMSMasterKeyID": "arn:aws:kms:region:account:key/key-id"
      },
      "BucketKeyEnabled": true
    }]
  }'

# Enable VPC Flow Logs
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Implement least privilege access
- Enable MFA everywhere
- Use service accounts for applications
- Encrypt data at rest and in transit
- Enable comprehensive logging
- Implement network segmentation
- Use secrets management
- Enable threat detection
- Regular security assessments
- Keep systems patched

### ❌ DON'T

- Use root/default credentials
- Store secrets in code
- Over-permissive security groups
- Disable encryption
- Ignore logs and monitoring
- Share credentials
- Skip compliance requirements
- Trust unverified data sources
