Email Header Analysis

Noun · Security & Infosec

Definitions

  1. The examination of routing metadata, authentication results, timestamps, sender fields, and relay paths in an email header to understand origin and detect spoofing or abuse. It is a basic but powerful skill in phishing triage and mail forensics.

    In plain English: Inspecting email metadata to see where a message really came from and how it was handled.

    Example: "Email header analysis showed the message failed SPF and actually originated from an unrelated host in another country."
