Latest Security Advisories (US-CERT)


CISA Releases Resource Guide for University Cybersecurity Clinics (2024.02.28)

Today, CISA released a Resource Guide for Cybersecurity Clinics to outline ways CISA can partner with and support cybersecurity clinics and their clients.

University cybersecurity clinics train students from diverse backgrounds and academic expertise to strengthen the digital defenses of non-profits, hospitals, municipalities, small businesses, and other under-resourced organizations. They can help address the national cyber workforce gap by developing a talent pipeline for cyber civil defense and helping students see themselves in a cybersecurity career.

CISA encourages clinics to engage with CISA and leverage the CISA resources outlined in the guide. CISA also encourages more universities to consider starting their own cybersecurity clinics as they play an important role in strengthening the cybersecurity posture of small organizations at the local level.

BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
