DHS’s Cybersecurity and Infrastructure Security Agency now gives agencies 15 days after discovery to fix vulnerabilities deemed critical.

Several key Department of Homeland Security cybersecurity services were disrupted last week after the Northern Virginia building they're housed in lost power during bad storms.

The new directive "introduces a more focused, integrated approach to addressing weaknesses across federal agency HVAs."

The NPPD chief outlined how the department is working with the private sector to help safeguard the nation’s most essential functions from cyberattacks.

Exercise participants will respond to a simulated global threat to infrastructure over the course of the three-day exercise.
