5.3 Disable Dormant Accounts
Where possible, delete or disable accounts that have been inactive for 45 days. Implementation Groups: IG1, IG2 and IG3 (part of the IG1 essential cyber hygiene baseline, so every enterprise applies it). Asset type: Users. Security function: Protect.
Source: CIS Controls v8.1, 5.3. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open CIS Controls v8.1 in the compliance library.
Each safeguard shows its Implementation Groups. IG1 is the essential baseline for every enterprise, IG2 adds to it, IG3 is all 153. Version 8.1 adds the Govern security function and asks for more processes to be documented; numbering is unchanged from v8.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.
