Sunday, November 30, 2008. Twenty years ago today was the first Computer Security Day, an event held annually to raise awareness of computer security issues.  I talk about the observation of Computer Security Day, and about the problem of computer malware such as viruses, which were beginning to become a serious problem in 1988.

The image at the right was the first Computer Security Day poster, created for the second CSD in 1989.  It, and all the CSD posters from the past 20 years, can be found at the Computer Security Day website.
