Activity under unusual conditions can indicate hostile activity. For example, what is normal activity during business hours can indicate hostile activity if it occurs during off hours. Depending on mission needs and conditions, account usage restrictions based on conditions and circumstances may be critical to limit access to resources and data to comply with operational or mission access control requirements. Thus, the operating system must be configured to enforce the specific conditions or circumstances under which organization-defined accounts can be used (e.g., by restricting usage to certain days of the week, time of day, or specific durations of time). |
