VPC Flow Log Analysis
Analyzing VPC flow logs (per-flow records of who talked to whom, when, and how much) to investigate cloud incidents, detect anomalies, and verify connectivity, a key cloud IR data source.
VPC flow logs record network connections inside the VPC: source, destination, ports, protocols, bytes, accepted/rejected. Analyzing them is a backbone cloud incident-response skill: understanding what an instance talked to, identifying lateral movement, finding command-and-control traffic, confirming what was or wasn't reachable. As a cloud-IR topic, fluency with flow-log analysis is one of the most useful cloud-investigation skills, complementary to control-plane and endpoint data.
Introduced in: Cloud Incident Response
Examples
- Tracing what an instance talked to using VPC flow logs during an investigation.
- Detecting lateral movement patterns in flow-log data.
- Confirming what was or wasn't reachable during incident analysis.
