PC security everyone’s responsibility: Don’t let yourself, coworkers become threat to our system Published Oct. 9, 2007 By 1st Lt. Stephanie Vidal and Mrs. Audrey Dubay 62nd Communications Squadron MCCHORD AIR FORCE BASE, Wash. -- Seldom a day goes by when the McChord Air Force Base Metropolitan Area Network (MAN) is not under surveillance or attack from an external threat. On average the 62nd Communications Squadron reports ten to 20 scans, probes, or attempts to gain access to our MAN. In many cases, these sources appear to be from other countries looking for an "open door." This is also known as scanning just like an unwanted visitor roaming the neighborhood for an open door. A probe is potentially a more serious threat where an intruder is standing at the doorstep looking in the window. An attempt is the most serious threat where the intruder is trying to turn the doorknob. Rest assured the 62nd CS has state-of-the-art equipment designed to defend against external intruders to our "network neighborhood." But what about the internal threat to our network? Unfortunately, you could be a part of that internal threat. "How do I become less of a threat?" you ask. Here are a few precautions you can take to prevent yourself from becoming a threat to the network: * Take your Common Access Card (CAC) with you when you walk away from your computer * Protect your CAC pin * Don't use an unauthorized modem to access network * Run virus scans on disks/USB drives prior to use * Information Assurance Officers (IAOs) and Client Support Administrators (CSAs) fix vulnerabilities immediately upon notification This list is not all inclusive, however, if we all practice these simple precautions we can lessen the likelihood of compromising our network. Remember the importance of Computer Security (COMPUSEC) when accomplishing your duties. Report any threats to our network to the Wing Information Assurance Office. Your vigilance as if in your own neighborhood will prevent our network from being compromised.
