Using an unordered list, summarize the following article with between 4 and 8 key points.
\nThe Cybersecurity and Infrastructure Security Agency (CISA) has issued Emergency Directive (ED) 26-03: Mitigate Vulnerabilities in Cisco SD-WAN Systems\u00a0and\u00a0Supplemental\u00a0Direction ED 26-03: Hunt and Hardening Guidance for Cisco SD-WAN Systems, in response to a significant cyber threat targeting federal networks utilizing certain Cisco systems and software. CISA has determined that these vulnerabilities pose an unacceptable risk to Federal Civilian Executive Branch (FCEB) agencies and require immediate action.
\n\u201cCISA remains unwavering in its commitment to protect our federal networks from malicious cyber threat actors despite the multi-week government shutdown of the Department of Homeland Security (DHS),\u201d said\u00a0CISA Acting Director Dr. Madhu Gottumukkala. \u201cOperational disruptions create strain and uncertainty, give our adversaries unnecessary advantages, and forces our frontline cybersecurity experts to carry out critical work without pay.\u00a0Based on collaboration with international partners and CISA\u2019s forensic analysis, the ease with which these vulnerabilities can be exploited demands immediate action from all federal agencies. We urge all entities to implement the measures outlined in this Emergency Directive without delay. CISA leadership and all (excepted) staff\u00a0remain\u00a0committed to fulfilling our mission while protecting the American people.\u201d
\nIn response\u00a0to\u00a0this threat, CISA released an\u00a0Alert\u00a0along with joint guidance,\u00a0Cisco SD-WAN Threat Hunt Guide, based on investigative data, to support network defenders\u2019 detection of and response to the malicious actors\u2019 threat activity. Authoring agencies include:<\/p>\n

United States National Security Agency (NSA)
\nUnited States Cybersecurity and Infrastructure Security Agency (CISA)
\nAustralian Signals Directorate\u2019s Australian Cyber Security Centre (ASD\u2019s ACSC)
\nCanadian Centre for Cyber Security (Cyber Centre)
\nNew Zealand National Cyber Security Centre (NCSC-NZ)
\nUnited Kingdom National Cyber Security Centre (NCSC-UK)<\/p>\n

CISA and the authoring organizations strongly urge network defenders to\u00a0immediately:
\n1)\u00a0Inventory:\u00a0all in-scope Cisco SD-WAN systems.
\n2)\u00a0Collect artifacts: including virtual snapshots and logs of SD-WAN systems.
\n3)\u00a0Patch: Cisco SD-WAN systems, including for\u00a0CVE-2026-20127\u00a0and\u00a0CVE-2022-20775.
\n4)\u00a0Hunt:\u00a0for evidence of compromise.
\n5)\u00a0Implement: as outlined in\u00a0Cisco\u2019s\u00a0Catalyst\u00a0SD-WAN\u00a0Hardening\u00a0Guide\u00a0and\u00a0review\u00a0their\u00a0blog.
\nAs agencies implement these requirements, CISA will\u00a0monitor\u00a0compliance, provide technical\u00a0assistance, and deliver\u00a0additional\u00a0resources as needed. This directive underscores CISA\u2019s commitment to using its cybersecurity authorities to gain greater visibility and drive\u00a0timely\u00a0risk reduction across federal civilian networks.
