Technical depth
Check command of COBIT 2019, ISO 27001 Annex A, NIST CSF and SOX ITGC control design; ask how they map controls to a policy framework and control library.
Evidence to listen for
- Command of the specific attack surface, tooling, and controls the role covers
- Understands how the underlying system works, not just how the tool reports on it
- Can explain an attack or control chain end to end
- Distinguishes what they found themselves from what a scanner flagged
Five-point scoring guide
Tool operator only; no understanding of the systems underneath.
Runs tooling but cannot explain findings or how the attack works.
Solid working knowledge; depth thins outside familiar tooling.
Strong command of the domain; explains attack and control chains clearly.
Names specific control objectives, explains ITGC scoping for change, access and operations, and distinguishes framework mapping from copy-paste adoption.
