hey all...
I would like to put a scenario..An employee has copied company sensitive dat in his USB mass storage device as per company policies the data has been encrpyted, but has accidentally formated it and then copies the data into the device,but this forgetting to encrypt it,and in the process losses the device...hence sensitive dat being at high risk.
What could be a solution?
Would a logic boomb on the pen-drive help????If so how would it work?
If not,what other solutions could be possible??
