Removal of Edge Devices by CISA Binding Operational Directive (BOD) 26-02, issued by CISA, directs Federal Civilian Executive Branch (FCEB) agencies to remove "end of support" (EOS) edge devices from their networks This article explores edge devices cisa. . The major security threats posed by unsupported hardware, such as firewalls, routers, and VPN gateways, that sit on network boundaries are addressed in this directive, which was created in collaboration with the Office of Management and Budget (OMB).

Edge devices that are no longer receiving security updates from their original equipment manufacturers (OEMs) must be phased out in accordance with BOD 26-02. CISA defines "edge devices" as any technology, such as load balancers, switches, and wireless access points, that are situated on the edge of a network and are reachable from the open internet.

Because unsupported devices can be exploited by advanced threat actors who use them as entry points into deeper agency networks, they are regarded as a "substantial and constant" threat. The directive specifies a rigorous deadline for adherence: Agencies must take immediate action to update any edge devices that are currently running EOS software to a supported version, as long as doing so doesn't interfere with mission-critical operations. Agencies must inventory their edge devices against a list of known EOS hardware provided by CISA and report their results within three months.

Agencies are required to inventory all other EOS devices in their environment and decommission all devices listed on CISA's original EOS list within a year.

All remaining EOS edge devices must be taken out of agency networks and swapped out for compatible substitutes within 18 months. Within 24 months: In order to detect and replace devices before they reach their end-of-support date, agencies must set up a continuous lifecycle management procedure. Because edge devices frequently integrate with identity management systems and have broad access to an organization's network, they are desirable targets for state-sponsored actors and cybercriminals.

Edge infrastructure frequently runs proprietary firmware that can be challenging to check or monitor, in contrast to endpoints (laptops, desktops), which have strong security software. Attackers have been able to get around perimeter defenses in recent campaigns by taking advantage of flaws in these devices. An attacker may be able to intercept traffic, steal credentials, or initiate additional attacks against internal systems after gaining access to a compromised edge device.

By implementing "proven lifecycle management practices," CISA's directive seeks to bridge this gap. Although BOD 26-02 specifically pertains to federal civilian agencies, CISA hopes that it will serve as a benchmark for other industries. "Unsupported devices should never remain on enterprise networks," CISA officials have said, calling on private companies, critical infrastructure operators, and local governments to follow suit.

According to OMB Memorandum M-22-09, this action is in line with the federal government's larger Zero Trust architecture objectives. Agencies lessen their attack surface and make it more difficult for hackers to gain access to federal systems by eliminating susceptible perimeter devices. OMB Circular A-130, which has long mandated that agencies phase out unsupported information systems, is also strengthened by the directive.

Agencies that disregard these regulations run the risk of exposing federal networks to known vulnerabilities for which there are currently no patches. CISA will offer an evolving list of EOS devices, reporting templates, and technical guidance to help with the transition. X, LinkedIn, and LinkedIn for daily ZeroOwl.
