Zscaler announced a Zero Trust Segmentation solution to provide a more secure, agile and cost-effective means to connect users, devices, and workloads across and within globally distributed branches, factories, campuses, data centers, and public clouds. While traditional networks, including SD-WAN and site-to-site VPN, have extended enterprise connectivity to branches and clouds, they have also inadvertently accelerated the spread of ransomware. Although firewalls are used to do segmentation on networks, they add complexity, increase costs, and … More →

CISA has added five 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.
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.
Today, the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), National Security Agency (NSA), and international partners released joint Cybersecurity Advisory, 2023 Top Routinely Exploited Vulnerabilities.
This advisory supplies details on the top Common Vulnerabilities and Exposures (CVEs) routinely exploited by malicious cyber actors and their associated Common Weakness Enumeration(s) (CWE) to help organizations better understand the impact of exploitation. International partners contributing to this advisory include:
The authoring agencies urge all organizations to review and implement the recommended mitigations detailed in this advisory. The advisory provides vendors, designers, and developers a guide for implementing secure by design and default principles and tactics to reduce the prevalence of vulnerabilities in their software and end-user organizations mitigations. Following this guidance will help reduce the risk of compromise by malicious cyber actors.
Vendors and developers are encouraged to take appropriate steps to provide products that protect their customers’ sensitive data. To learn more about secure by design principles and practices, visit CISA’s Secure by Design.
CISA released five Industrial Control Systems (ICS) advisories on November 12, 2024. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.
CISA encourages users and administrators to review newly released ICS advisories for technical details and mitigations.
Citrix released security updates to address multiple vulnerabilities in NetScaler ADC, NetScaler Gateway, and Citrix Session Recording. A cyber threat actor could exploit some of these vulnerabilities to take control of an affected system.
CISA encourages users and administrators to review the following and apply necessary updates:
The Cybersecurity and Infrastructure Security Agency (CISA), through the Joint Cyber Defense Collaborative (JCDC), enabled proactive coordination and information sharing to bolster cybersecurity ahead of the 2024 Olympic and Paralympic Games in Paris. Recognizing the potential for cyber threats targeting the Games, CISA worked to strengthen U.S. private sector ties and facilitate connections with key French counterparts to promote collective defense measures.
Utilizing its role as a key facilitator between public and private sector partners, JCDC established monitoring channels and launched cyber threat information-sharing forums to prepare for significant incidents. Throughout the Games, JCDC industry partners remained vigilant, promptly alerting CISA to any potential impacts on Olympic and Paralympic activities. This allowed CISA to provide prompt updates and share critical information with the French Agence Nationale de la Sécurité des Systèmes d'Information to aid swift response efforts.
This collaboration underscores JCDC’s essential role in uniting global partners to defend against cyber challenges that threaten national security and international events. The partnership highlights the value of voluntary information sharing to build trust and strengthen the protection of critical infrastructure in an evolving threat landscape.
