Secure Name and Address Resolution - Security Status of Child Zones, v1.0

Defines conformance and assessment criteria for compliance with minimum security requirements for secure name and address resolution - security status of child zones as related to overall system and communications protection 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.

1
Secure Name and Address Resolution - Security Status of Child Zones (SecureNameandAddressResolution-SecurityStatusofChildZones)

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