Response To Audit Processing Failures | Configurable Traffic Volume Thresholds, v1.0

Defines conformance and assessment criteria for verifying that an information system enforces configurable network communications traffic volume thresholds reflecting limits on auditing capacity and rejects or delays network traffic above those thresholds.
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.

Assessment Step

1
Response To Audit Processing Failures | Configurable Traffic Volume Thresholds (ResponseToAuditProcessingFailuresConfigurableTrafficVolumeThresholds)
Does the information system enforce configurable network communications traffic volume thresholds reflecting limits on auditing capacity and [Selection: rejects; delays] network traffic above those thresholds?
Artifact
A1
Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
Parameter
Network Traffic Handlingrequired
ENUM_MULTI : Select the action taken when network auditing capacity thresholds are exceeded.
  • traffic rejected
  • traffic delayed
If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

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.
