What is Computer Security Day?
Computer Security Day on November 30 was started in 1988 by a Washington, D.C. chapter of the Association for Computing Machinery, the same month the Morris worm spread across the early internet. It began as a way to make people think about protecting their computers and data, at a time when few home users did. Today it is a reminder to update devices, use a password manager and two-factor authentication, back up important files and watch out for phishing messages.
