COMPUTER SECURITY DAY was started in 1988 to help raise awareness of computer related security issues.

The CSD is an annual event held on November 30th in some countries although some organizations can choose the date of celebration

The Computer Security Department / UNAM-CERT of the General Direction of Academic Computer Services in UNAM is the oficial organization in Mexico that celebrate the DISC since 1994.

For 2007 the theme for CSD is: "Taking Action." Through the CSD will try that each organization and each individual is responsible for protecting information assets and resources, due to the fact that every person inside an organization plays an important role in the computer security. The administrators and users are mandated to create a Responsable Security through the implementation of security like: installation, update and administration of antivirus software, personal firewalls or antispyware among others.
