Computer Compromises

In spite of efforts, any computer can be compromised. Most of the systems compromised on campus are desktops running the Microsoft Windows operating system. Windows computers account for over 90% of the compromised machines that we identify. For compromises other than some simple virus infections, the Network Security Center requires that the computer's disk be reformatted, the operating system be reinstalled from the original media, and that files be restored from a backup medium. These steps will be required before a computer is restored to the network. It is, therefore, important to minimize the chance of a compromise. The University experiences dozens of identifiable attacks per day, each attempting to compromise hundreds of machines. Placing a computer on the network for even a short period of time without taking precautions to protect it makes it likely that it will be compromised. If a computer is repeatedly compromised, it may be removed from the network indefinitely.
