SPAR - Security Preparedness and Response

The Office of Cybersecurity welcomes you to SPAR, our Security Preparedness and Response initiative. As we plan engagements and training material around cybersecurity related topics, we would like to know which areas of security interest you the most. We are asking for a minute of your time to take a two-question survey about cybersecurity related topics.

No, this is not a test to see if you will click on a link in an email. If you are not comfortable clicking a link for the survey, please copy and paste this into your browser:
