Malicious Code Protection - Periodic Scans, v1.0

Defines conformance and assessment criteria for compliance with minimum security requirements for malicious code protection - periodic scans as related to overall system and information integrity requirements.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; <organization-defined frequency>]), the option(s) implemented by the organization must also be defined and documented.
