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:

# 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
