Ever since I have kept a password protected screensaver on every computer.
The first day my business got desktops in the 1990’s someone slipped into somebody else’s office and sent an insulting email to another as a “joke.”
We used to go into offices with unsecured systems and send an email to the unit from the individual explaining that they had so much fun in COMPUSEC/Information Protection training that they were going to attend again.
If the “ROMADs” found one of their collegues left their computer open they would send an internal “gay” email to the TACP community.
Fun days in the ASOS.
