Systems security interview preparation
Systems questions check whether you know how privilege actually works on the operating systems you defend, and whether you can turn a hardening standard into a decision. Expect to be asked how an attacker escalates on a host, and what you would change to make that harder.
Commonly asked for: Security Engineer, Infrastructure Security Analyst, Blue Team Engineer.
