AWS Incident Response Automation

Event-Driven Containment with Lambda + CloudWatch

Serverless incident response workflows that enrich, classify, and contain cloud security events automatically — collapsing manual triage from minutes to seconds.

## Problem

Cloud security alerts arrived in chat with no context. Analysts spent the first ten minutes of every incident gathering the same enrichment from the console.

## Pipeline

CloudWatch and EventBridge route security events to Lambda enrichers that pull IAM context, network exposure, and tag metadata. High-confidence events trigger containment actions — SG isolation, key revocation, snapshot for forensics — before paging humans.

## Outcome

Materially lower MTTR, fewer late-night pages for noise, and a repeatable serverless pattern other teams reuse for their own event sources.
