The information system provides a warning to organization-defined personnel, roles, and/or locations within an organization-defined time period when allocated audit record storage volume reaches an organization-defined percentage of repository maximum audit record storage capacity.

Implementation Guidance

The organization being inspected/assessed configures the information system to immediately provide a warning to personnel, roles, and/or locations defined in AU-5 (1), CCI 1852 when allocated audit record storage volume reaches 75 percent of repository maximum audit record storage capacity. DoD has defined the time period as immediate. DoD has defined the percentage as 75 percent. For information system components that have applicable STIGs or SRGs, the organization being inspected/assessed must comply with the STIG/SRG guidance that pertains to CCI 1855.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed has configured the information system to immediately provide a warning to personnel, roles, and/or locations defined in AU-5 (1), CCI 1852 when allocated audit record storage volume reaches 75 percent of repository maximum audit record storage capacity. DoD has defined the time period as immediate. DoD has defined the percentage as 75 percent. For information system components that have applicable STIGs or SRGs, the organization conducting the inspection/assessment evaluates the components to ensure that the organization being inspected/assessed has configured the information system in compliance with the applicable STIGs and SRGs pertaining to CCI 1855.
