Missouri's Office of Administration, Information Services and Technology Division

Missouri's Office of Administration, Information Services and Technology Division (OA-ITSD) serves as the central information technology authority for the state government of Missouri. As a division within the state's Office of Administration, its core function is to provide enterprise-wide IT services, infrastructure, and support to various state agencies and departments. This includes managing critical systems that facilitate government operations, data processing, and inter-agency communication. A key component of its operational footprint is the administration of the state's MOVEit file transfer system, a secure platform used for exchanging sensitive data. The division's role encompasses the implementation, maintenance, and security of such foundational technologies, positioning it as a pivotal entity in the state's digital infrastructure. Its work directly supports the continuity and efficiency of public services across Missouri's executive branch.

The division's significance and operational challenges were highlighted by the cyberattack discovered on May 31, 2023. OA-ITSD launched an investigation after its MOVEit system was compromised by the Clop ransomware group, which exploited a known software vulnerability. This incident underscores the division's responsibility for safeguarding state data and its exposure to sophisticated cyber threats targeting government entities. The investigation's scope, as publicly stated, involves determining the full extent of the breach and identifying all potentially impacted state agencies, vendors, and individuals. This event illustrates the division's critical function in cybersecurity incident response and its role in coordinating the state's recovery efforts following a major security breach. The ongoing assessment and planned public notification reflect its mandated duty to ensure transparency and protect the interests of Missouri's citizens and its governmental partners. As a state-level IT division, its structure is inherently that of a governmental subunit without separate corporate ownership, operating under the direct authority of the Missouri Office of Administration.
