FILED UNDER
Proving who someone is, then deciding what they may reach: authentication, single sign-on, and the access control models. Kerberos goes deepest, with the attack chain built on it (golden tickets, silver tickets, Kerberoasting). CISSP Domain 5.
How a system is designed to be secure before anything is bolted on: the formal models that decide who may read and write what, the cryptography underneath, and the principles that hold when real systems get messy. CISSP Domain 3.
Planning for the day the system is gone: how long you can be down, how much data you can afford to lose, and where you fail over to. Impact analysis, recovery sites, and the metrics that all sit on one timeline. CISSP Domains 1 and 7.
How to think like a manager on exam day: reading a scenario for what it is really asking, spotting the distractors, and holding the fine distinctions that decide close questions. Scoping against tailoring, due care against due diligence.
Putting a number on risk, then deciding what to do about it: quantification, treatment and appetite, control types, and threat modeling. Plus the data governance vocabulary that decides classification questions. CISSP Domains 1 and 2.
How networks are secured and attacked: the OSI model layer by layer, the protocols that encrypt traffic in transit, and segmentation from VLANs up to micro-segmentation, so that one breach cannot reach everything. CISSP Domain 4.
Running security day to day: watching what is happening now, testing your own defences before somebody else does, and handling it properly when something goes wrong, from incident response to chain of custody. CISSP Domains 6 and 7.
Building security into software rather than bolting it on afterwards: where security fits in the development life cycle, what DevSecOps changes, and the testing that finds flaws in your code and in your dependencies. CISSP Domain 8.
How a business impact analysis finds critical functions, measures impact over time, maps dependencies, and produces the recovery priorities strategy must meet.
The five phases of the BCP lifecycle, how BCP differs from DRP, who is accountable for the programme, and the six testing methods in order of disruption.
The five quantitative risk formulas in the order they run, worked end to end from asset value to a funded decision, plus where the method breaks down.
Email authentication for the CISSP: what SPF, DKIM and DMARC each check, why forwarding breaks SPF, and how alignment ties a pass to the visible From.
How a TOCTOU race condition turns a passed security check into an exploit, why symbolic links make it dangerous, and how to close the window.
