# AWS Misconfiguration

## Overview
AWS misconfigurations are responsible for major data breaches. Common issues:
1. **Public S3 buckets**: Accidental public-read or public-write ACL
2. **IAM wildcard policies**: `Action: "*"` grants all permissions
3. **Hardcoded AWS credentials**: Access keys in source code
4. **Unencrypted RDS/S3**: Data at rest not encrypted
5. **Overly permissive security groups**: Port 22 or 3306 open to `0.0.0.0/0`
6. **CloudTrail disabled**: No audit trail

## Remediation
- Enable S3 Block Public Access at the account level
- Apply principle of least privilege to all IAM policies
- Use IAM roles instead of hardcoded credentials
- Enable encryption at rest for all services
- Use VPC security groups with minimal required access
