8.6 Collect DNS Query Audit Logs

Where it is suitable and supported, collect logs of DNS queries made by enterprise assets. Implementation Groups: IG2 and IG3 (not in the IG1 baseline; applies from IG2 upward). Asset type: Data. Security function: Detect.

Source: CIS Controls v8.1, 8.6. 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.

Scope: Implementation Groups: IG2, IG3. Security function: Detect; asset type: Data.

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.

where the evidence lives
teal = a system already holds it · olive = produced at each review. To go live: easy when half or more of the artefacts are already held by a system, moderate from a quarter to a half, hard below a quarter.

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.
