In a significant move, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) announced on Thursday that it will be discontinuing ten emergency directives (Eds) issued between 2019 and 2024. This decision marks the end of an era for federal cybersecurity measures aimed at addressing urgent threats.
The emergency directives that are now officially closed include:
- ED 19-01: Focused on mitigating DNS infrastructure tampering, which is vital for maintaining the integrity of online communications.
- ED 20-02: Addressed vulnerabilities in Windows systems identified during the January 2020 Patch Tuesday, ensuring users could safeguard their systems effectively.
- ED 20-03: Targeted the Windows DNS server vulnerability revealed in July 2020, which posed serious risks of remote code execution.
- ED 20-04: Dealt with the Netlogon elevation of privilege vulnerability from August 2020, crucial for protecting user access levels.
- ED 21-01: Responded to the SolarWinds Orion code compromise, a high-profile incident that affected numerous organizations.
- ED 21-02: Focused on vulnerabilities within Microsoft Exchange on-premises products, reinforcing email security.
- ED 21-03: Aimed at mitigating vulnerabilities in Pulse Connect Secure products, essential for secure remote access.
- ED 21-04: Tackled vulnerabilities in the Windows Print Spooler service, which could have been exploited to gain unauthorized access.
- ED 22-03: Concentrated on vulnerabilities found in VMware products, highlighting the need for comprehensive virtualization security.
- ED 24-02: Mitigated significant risks associated with nation-state compromises targeting Microsoft’s corporate email system, underlining the critical nature of email security in federal operations.
CISA explained that these directives were established to protect Federal Civilian Executive Branch (FCEB) agencies from potential cyber threats. The agency collaborated closely with various federal entities to resolve these issues, implement best practices, and build a more robust digital infrastructure.
The goal of issuing such directives is to ensure timely action against emerging threats. According to CISA, the necessary measures have either been successfully implemented or are now being enforced through Binding Operational Directive (BOD) 22-01, which focuses on reducing the significant risk posed by known exploited vulnerabilities.
Madhu Gottumukkala, the Acting Director of CISA, emphasized the agency's role in enhancing federal cybersecurity. "As the operational lead for federal cybersecurity, CISA utilizes its authority to fortify federal systems and protect against unacceptable risks, particularly those from hostile nation-state actors," Gottumukkala stated. "The conclusion of these ten Emergency Directives showcases CISA's dedication to operational collaboration across the federal landscape."
Every day, CISA's talented team collaborates with partners to eliminate persistent security threats, counteract new dangers, and provide real-time guidance for mitigation. Looking ahead, CISA aims to further advance the principles of "Secure by Design," which prioritize transparency, configurability, and interoperability, enabling all organizations to better defend their varied environments.
