detection-and-monitoring skillA
detection-and-monitoring is agent-read markdown (skill) from cbrock84/headcount: 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 c.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260916.e72e404mdr add cbrock84/headcount/detection-and-monitoring@sha256:5c6390c0dce914a5Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
