## What this funds

Program Overview Interior operates one of the most distributed, complex IT environments across the Federal government. Cybersecurity funding supports detecting and preventing major cyberattacks by managing technology assets, protecting trusted internet connections, and protecting email.The Office of the Chief Information Officer (OCIO) uses this funding for hardware, software, and services to detect and respond to cybersecurity attacks, protect against malicious software, analyze IT security risks, and support implementing critical network defenses Departmentwide.The OCIO is committed to maximizing efficiencies created in the realignment of Interior's IT organization by identifying and eliminating duplication of cybersecurity efforts, tools, and resources, thereby reducing costs while prioritizing implementation of the administration's agenda. Zero Trust Successfully modernizing the Federal government's approach to security requires a government-wide effort.Consistent with prevailing guidance and cybersecurity best practices, the Federal government is transitioning to a Zero Trust approach to security. The foundational tenet of a Zero Trust model is that no actor, system, network, or service operating outside or within an organization's security perimeter is trusted.Instead, agencies must verify everything attempting to establish access.It is a dramatic paradigm shift in the philosophy of how agencies secure infrastructure, networks, and data, from verifying once at the perimeter to continually verifying each user, device, application, and transaction. Program Performance The Department recognizes that outdated IT systems increase security risks and vulnerabilities and is committed to taking decisive actions to prioritize, modernize, and secure its IT resources and assets.The OCIO will focus on high-priority actions such as: Continuing to implement a Security Information and Event Management (SIEM) system: � The budget continues the funding necessary to implement a Security Information and Event Management (SIEM) system. This key enterprise-wide security tool ties system event data together for a comprehensive view of IT security to protect against and mitigate cyber events. Addressing Zero Trust Strategic Pillars: � The 2027 budget request explicitly funds cybersecurity efforts tied to: o Networks: WCF-14 Working Capital Fund
