detecting with a sensor integrated in the information handling system at least a first sensed condition indicating absence of the user from a predetermined proximity with the information handling system; and

in response to the detecting, altering the monitoring to deauthorize all access through the information handling system in the event of a detection of hot plug event at a port of an information handling system, the hot plug event associated with insertion of a portable storage device into the port.

10. The method of claim 9 wherein detecting with a sensor integrated in the information handling system at least a first sensed condition indicating absence of a user from a predetermined proximity with the information handling system further comprises:

deauthorizing at least a portion of the access after a predetermined time elapses at a timer without a user input;

sensing with a camera that captures images proximate the information handling system the lack of an end user in the image.

11. The method of claim 10 wherein the deauthorizing further comprises deauthorizing access to all password protected information.

12. The method of claim 11 wherein multimedia information currently presented at the information handling system continues being presented after the predetermined time.
