Description
The device lock function prevents further access to the system by initiating a session lock after a period of inactivity or upon receiving a request from a user. The device lock is retained until the user reestablishes access using established identification and authentication procedures. A device lock is a temporary action taken when a user stops work but does not want to shut down because of the temporary nature of the hiatus. During the device lock a publicly viewable pattern is visible on the associated display, hiding what was previously visible on the screen. Once invoked, the device lock shall remain in place until the user re-authenticates. No other system activity aside from re-authentication can unlock the system. The operating system must lock the device after the organization defined time period. This prevents others from gaining access to the device when not in the user's possession and accessing sensitive DoD information. A device lock mitigates the risk that an adversary can access data on an unattended mobile device but only after the maximum of 15 minute period of inactivity.
