This website is the premier destination for accessing security awareness courses for DoD and other U.S. Government and defense industry personnel who do not require transcripts to fulfill training requirements for their specialty.

A certificate is provided after the course is completed; however, there is no record maintained by CDSE. Additional eLearning and instructor-led courses, that CDSE maintains a record of, are available on the CDSE Learning Management System called STEPP. To view these additional courses, please see the complete course catalog at

Ransomware Video

We are aware of reports of ransomware known as 'WannaCry' affecting multiple global entities. To increase our collective defenses across the Department and Federal networks, we urge all employees to take three actions:
  1. Do not click on links or download files in emails unless you know for sure they are intended for you;
  2. Ensure your personal devices are updated and patched; and,
  3. Backup your data so you can recover your systems if they become infected. Microsoft released a patch in March that addresses this issue.
