MS.EXO.9.5v1 - At a minimum, click-to-run files SHOULD be blocked (e.g., .exe, .cmd, and .vbe).

Information

Malicious attachments often take the form of click-to-run files. Blocking a list of common executable files helps mitigate the risk of adversarial exploitation.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Any product meeting the requirements outlined in this baseline policy may be used. If the agency uses Microsoft Defender, see the following implementation steps for [enabling preset security policies](https://github.com/cisagov/ScubaGear/tree/v1.5.0/PowerShell/ScubaGear/baselines/defender.md#implementation), which disallow click-to-run file types.
