Review — Reading a Host
What is it?
A review of Module 1: why the endpoint is central, its attack surface, Windows architecture, users and privileges, and the Linux mapping — the mental model of a host that everything after this depends on.
Why it matters
Every later skill — investigation, containment, hardening — assumes you can read a host: its processes, services, privileges and persistence points. This module is that foundation.
Where you see it
The baseline understanding behind every endpoint task.
What normal looks like
A host read correctly: normal structure recognized, so anomalies stand out.
What suspicious looks like
Not applicable at review level.
How analysts investigate
By building and keeping a mental model of normal host structure, so any deviation — process, service, privilege, persistence — is immediately notable.
Common beginner mistakes
- Trying to investigate a host without the architecture model — every process looks equally plausible, and the one impossible lineage goes unseen.
Assemble the host-reading model: the endpoint is where attacks act; its surface is everything not-yet-reduced; its Windows structure is processes/services/registry/memory governed by user tokens and privileges; and Linux mirrors it with systemd/cron/sudo. Hold this model, and the anomalies the next modules hunt — the impossible parent, the rogue service, the elevated clerk — become visible the moment they appear.
