CISA, NSA, and ODNI Release Guidance for Customers on Securing the Software Supply Chain  17 Nov 2022, 5:00 pm

Today, CISA, the National Security Agency (NSA), and the Office of the Director of National Intelligence (ODNI), published the third of a three-part series on securing the software supply chain: Securing Software Supply Chain Series - Recommended Practices Guide for Customers. This publication follows the August 2022 release of guidance for developers and October 2022 release of guidance for suppliers.

The guidance released today, along with the accompanying fact sheet, provides recommended practices for software customers to ensure the integrity and security of software during the procuring and deployment phases.

The Securing Software Supply Chain Series is an output of the Enduring Security Framework (ESF), a public-private cross-sector working group led by NSA and CISA. This series complements other U.S. government efforts underway to help the software ecosystem secure the supply chain, such as the software bill of materials (SBOM) community.

CISA encourages all organizations that participate in the software supply chain to review the guidance. See CISA’s Information and Communications Technology (ICT) Supply Chain Risk Management Task Force, ICT Supply Chain Resource Library, and National Risk Management Center (NRMC) webpages for additional guidance.

CISA Has Added One Known Exploited Vulnerability to Catalog     14 Nov 2022, 5:08 pm

CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. This type of vulnerability is a frequent attack vector for malicious cyber actors and pose significant risk to the federal enterprise. Note: To view the newly added vulnerabilities in the catalog, click on the arrow in the "Date Added to Catalog" column, which will sort by descending dates.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known CVEs that carry significant risk to the federal enterprise. BOD 22-01 requires 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.
