Signal needs context

WHAT HAPPENS IN THIS STAGE

01
Receive the signal
Read the alert, severity, host and initial process information from the approved SIEM source.

A methodology alert is neither good nor bad on its own; requires business and technical context.
03
Open the evidence trail
Record the question, source and first observation so the later verdict can be audited.
