Officials with the Des Moines Area Community College (DMACC) say cybersecurity concerns forced them to take some of their computer systems offline, Thursday, following the discovery of security problems. As a result, online classes were canceled Thursday.

KCCI reports cybersecurity teams were in the process of checking DMACC’s system. The college said there is no evidence that any student or faculty information has been compromised, but they said their investigation is still underway.
