CISSP in Twelve Weeks

Twenty-five modules, eight domains, one learner. By week 12 you can answer any CISSP question the way a risk owner would, and you have written Hermetic's security program in the exam's own language along the way.

The question behind every module: what would the person accountable for this risk decide, and why?

Start module 01 Start with practice

The three tracks

CISSP in Twelve Weeks in three tracks: the risk owner's view, the technical core, then operate, assess, build and the exam — Track 1 is where the learner is weakest and the exam is heaviest. Track 2 is familiar ground with new names. Track 3 closes with operations, software and the exam itself.

Concepts first

Work the 25 modules in order, three a week. Each ends with a written artifact and a module check.

Practice first

Start from twenty decisions Hermetic makes, with the exam's vocabulary arriving only when the problem needs it.

Modules

How a week runs

Three modules

Read the module, then the matching book chapter, then do the module check. About two and a half hours each in Tracks 1 and 2.

Two practice decisions

Each problem is a real client decision. Write the artifact before you read the vocabulary section.

One review hour

Reopen last week's Common trap sections and redo the faded practice without the solution open.

One tutor session

Open this folder in Claude Code and say "quiz me on module 03". The tutor poses first and corrects one thing at a time.

The full 12-week plan

Twenty decisions Hermetic makes

Each problem is a question an MSP owner asks before knowing the CISSP word for it. Pick one, write your first answer, and the exam's vocabulary arrives once the problem needs it. Three tracks: footholds, tools, and judgment.

How a CISSP attacks a question

Ten moves. Each has a cue that tells you to reach for it, the steps, a worked trace that rejects a rival move, and the case where it misleads. The drills at the bottom ask only one thing: which move first?

Pick the move
