CCI-000044

Enforce the organization-defined limit of consecutive invalid logon attempts by a user during the organization-defined time period.

Implementation Guidance

The organization being inspected/assessed configures the information system to limit invalid logon attempts by a user to three attempts during a 15 minute time period. 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 44. DoD has defined the maximum number as three. DoD has defined the time period as 15 minutes.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures the information system to limit invalid logon attempts by a user to three attempts during a 15 minute time period. 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 44. DoD has defined the maximum number as three. DoD has defined the time period as 15 minutes.

Compelling Evidence

1.) Signed and dated access control policy 2.) Applicable STIG/SRG checks 3.) Documentation that shows the system is configured to limit invalid logon attempts by a user to three attempts during a 15 minute time period.
