Next Steps

1. Immediate Actions (24-48 hours)

   • Remove root access keys
   • Enable CloudTrail in all regions
   • Update security group rules

2. Short-term (1-2 weeks)

   • Implement MFA for all IAM users
   • Enable encryption on RDS instances
   • Set up CloudWatch log retention

3. Medium-term (1-2 months)

   • Restructure IAM policies
   • Enable S3 versioning
   • Implement VPC flow logging
