Apple has released security updates to address vulnerabilities in multiple products. An attacker could exploit some of these vulnerabilities to take control of an affected device.
CISA encourages users and administrators to review the following advisories and apply the necessary updates.
CISA has released an update to the Zero Trust Maturity Model (ZTMM), superseding the initial version released in September 2021. ZTMM provides a roadmap for agencies to reference as they transition towards a zero-trust architecture. ZTMM also provides a gradient of implementation across five distinct pillars to facilitate federal implementation, allowing agencies to make minor advancements toward optimization over time.
The objective of this update is to facilitate the distribution of the ZTMM Version 2 and educate federal civilian agencies on the updated ZTMM and its application to their zero-trust implementations. CISA encourages state, local, tribal, and territorial governments, and the private sector to use ZTMM as a baseline for implementing zero trust architecture.
CISA released two Industrial Control Systems (ICS) advisories on April 11, 2023. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.
CISA encourages users and administrators to review the newly released ICS advisories for technical details and mitigations.
CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.
These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. Note: To view other 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 Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. 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.
Cisco has released security advisories for vulnerabilities affecting multiple Cisco products. A remote cyber threat actor could exploit these vulnerabilities to take control of an affected system.
CISA encourages users and administrators to review the following advisories and apply the necessary updates:
