Privacy Act of 1974; System of Records

Official abstract: Pursuant to the provisions of the Privacy Act of 1974, as amended, the Department of Housing and Urban Development (HUD), Office of Chief Information Officer (OCIO), and Infrastructure and Operations (IOO), is issuing a public notice of its intent to establish a Privacy Act System of Records Notice (SORN) titled "Sumo Logic." Sumo Logic serves as HUD's Security Information and Event Management (SIEM) tool, supporting centralized log collection, aggregation, and security monitoring. It collects system log data from HUD applications, infrastructure, security tools, and cloud platforms, and performs event correlation, custom searches, dashboard monitoring, scheduled reporting, and other standard security monitoring. This newly established system will be included in HUD's inventory of record systems. HUD had previously published a SORN for this system on June 10, 2026 (91 FR 35248). However, the underlying authority was revoked and replaced. Accordingly, HUD withdraws the SORN published on June 10, 2026, and instead publishes this SORN with the updated authority.
