# AWS Security Scanner Skill

## Purpose

Automated AWS security configuration scanning and hardening to identify misconfigurations, compliance violations, and security risks across AWS accounts and organizations.

## Capabilities

### Prowler Security Assessments
- Run comprehensive Prowler security scans
- Execute CIS AWS Foundations Benchmark checks
- Run AWS Well-Architected security pillar assessments
- Check PCI DSS, HIPAA, GDPR compliance
- Generate multi-format reports (HTML, CSV, JSON)

### IAM Security Analysis
- Analyze IAM policies for over-permissive access
- Check for unused credentials and access keys
- Identify IAM users without MFA
- Review cross-account access configurations
- Detect privilege escalation paths
- Analyze service control policies (SCPs)

### S3 Bucket Security
- Identify publicly accessible buckets
- Check bucket encryption configurations
- Review bucket policies and ACLs
- Verify access logging enabled
- Check for sensitive data exposure
- Validate versioning and replication

### Network Security Analysis
- Review security group configurations
- Analyze Network ACLs
- Check VPC flow log enablement
- Identify public-facing resources
- Validate VPC endpoint configurations
- Check for overly permissive rules

### Encryption Verification
- Verify EBS volume encryption
- Check RDS encryption settings
- Validate S3 encryption configurations
- Review KMS key policies
- Check secrets manager configurations
- Verify certificate validity

### Logging and Monitoring
- Validate CloudTrail configuration
- Check CloudWatch log retention
- Verify GuardDuty enablement
- Review Security Hub findings
- Check Config rule compliance
- Validate alarm configurations

### Compliance Mapping
- Map findings to CIS Benchmarks
