Cybersecurity

How to decide what a system must protect, and how you would notice if it failed.

One lab a week. The group reviews a small system: what matters, what is exposed, and which records would let you see trouble.

A written defense of a design on your own clock. You name impacts and the habits that keep a failure from shipping.

  1. 01

    What is worth protecting

    Assets, people, and the failures that would actually matter.

  2. 02

    Identity and access

    Who is allowed to do what, drawn so someone else can check it.

  3. 03

    How web applications fail

    Classes of failure and their impact, and the habits that close them.

  4. 04

    A network as a map

    Enough structure to say where a control belongs.

  5. 05

    Logs that notice trouble

    The record you would want, and the data you would refuse to keep.

  6. 06

    Failing more safely

    Defaults, secrets, and what happens when a part is wrong.

  7. 07

    A defense review

    One small system, written up so an owner could act on it.
