Intrusion Analysis

Definitions

1. The investigation of malicious activity inside an environment to determine how attackers entered, what they did, what they touched, and whether they still have access. Intrusion analysis often combines endpoint, identity, and network evidence to reconstruct attacker behavior.

   In plain English: Analyzing a break-in to understand how attackers got in and what they did.

   Example: "The team began intrusion analysis as soon as the EDR alert suggested hands-on-keyboard activity on a finance server."
