Title

The UEM server must enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period. (Cat II impact)

Check Content

Requirement is Not Applicable when the UEM server is configured to use DoD Central Directory Service for administrator account authentication. Verify the UEM server enforces the limit of three consecutive invalid logon attempts by a user during a 15-minute time period. If the UEM server does not enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period, this is a finding.
