CCI-002238

Automatically lock the account or node for either an organization-defined time period, until the locked account or node is released by an administrator, or delays the next logon prompt according to the organization-defined delay algorithm when the maximum number of unsuccessful logon attempts is exceeded.

Implementation Guidance

The organization being inspected/assessed configures the information system to automatically lock the account or node until the locked account is released by an administrator and delays the next login prompt for a minimum of 5 seconds when the maximum number of unsuccessful attempts is exceeded. 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 2238. DoD has defined the delay algorithm as a minimum of 5 seconds. DoD has defined the time period as until released by an administrator.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures the information system to automatically lock the account or node until the locked account is released by an administrator and delays the next login prompt for a minimum of 5 seconds when the maximum number of unsuccessful attempts is exceeded. 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 2238. DoD has defined the delay algorithm as a minimum of 5 seconds. DoD has defined the time period as until released by an administrator.
