Computer Security Day

Computer Security Day is a holiday that falls near the end of November on November 30th. This is a day when everyone is encouraged to take the time to consider whether their computers and online data are as secure as they could be.

This is extremely important because people’s computers now contain a wealth of information that they wouldn’t want to fall into the wrong hands—data that includes banking and medical information, personal photos, email addresses, and social media accounts. Needless to say, this information needs to be protected.

The History of Computer Security Day

Computer security is a concept that goes back over 33 years—although many people might not be aware of that fact. It was started in November of 1988 when researchers at Cornell University discovered an unknown virus in their computer systems.

It was only a few hours after they discovered this virus—a virus known as the Morris Worm—that it had spread through other computer systems at the university and even made its way into ARPANET, the first wide-area packet-switching network with distributed control. ARPANET was an earlier and limited version of the internet that was established by the Advanced Research Projects Agency of the U.S. Department of Defense.

Almost a week after the discovery of the Morris Worm, the U.S. Defense Advanced Research Projects Agency (DARPA) recommended that a National Computer Infection Action Team be established to deal with future virus attacks. They then recommended establishing a day to raise awareness about computer security. It has been observed ever since.
