Builds the capability to notice an attack in progress — deciding what to log and retain, centralizing it somewhere tamper-resistant, writing detections that fire on attacker behavior rather than on individual events, tuning out the noise that trains people to ignore alerts, and defining what happens when something fires. Use this to design or assess monitoring coverage, work out why an incident went unnoticed, cut alert volume without losing signal, or decide what a detection capability should…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Detection and monitoring Incident response assumes someone noticed. Most organizations that respond well to incidents found out from a customer, a vendor, or an extortion note, and the gap between compromise and discovery is where nearly all of the damage accumulates. ## Decide what to log by asking what you would need afterward Work backwards from the questions an investigation asks: who authenticated, from where, and what did they then do. That points at a short list that matters far more than volume. - **Identity events** — authentication success and failure, MFA changes, privilege grants, new API keys and tokens, consent grants to applications. - **Endpoint process activity** — what ran, what spawned it, what it connected to. - **Administrative actions** in the platforms that hold your data, especially permission and sharing changes. - **Network egress** where you have it, and DNS, which is cheap and unusually informative. **Retention decides whether you can investigate at all.** Intrusions are commonly discovered months after entry, so logs kept for thirty days answer none of the useful questions. Split it: a short …

How to install
mdr add cbrock84/headcount/detection-and-monitoring@sha256:5c6390c0dce914a5The line at the top of this page pins the label git:20260916.e72e404, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
