Individual skill

performing-cloud-log-forensics-with-athena

Uses AWS Athena to query CloudTrail, VPC Flow Logs, S3 access logs, and ALB logs for forensic investigation. Covers CREATE TABLE DDL with partition projection, forensic SQL queries for detecting unauthorized access, data exfiltration, lateral movement, and privilege escalation. Use when investigating AWS security incidents or building cloud-native forensic workflows at scale.

## Helper prerequisites

This bundled skill supplies methodology text; it does not install the local helper files invoked below. Before running a command using `agent.py` or a `scripts/` path, create that file from a complete implementation when one is supplied, or obtain and review the matching upstream helper. Check its `--help` and dependencies against the shown arguments. If no implementation is available, the invocation is a workflow illustration rather than a runnable command; use the documented underlying tools instead.


# Performing Cloud Log Forensics with AWS Athena

## When to Use

- When investigating AWS security incidents that require querying massive volumes of cloud logs
- When performing forensic analysis across CloudTrail, VPC Flow Logs, S3 access logs, and ALB logs
- When building reusable Athena tables with partition projection for ongoing incident response
- When hunting for indicators of compromise across multiple AWS log sources simultaneously
- When creating evidence-grade SQL queries for compliance audits or legal proceedings
