This threat detection rule identifies Windows endpoints that have not recorded a successful Windows update in the past 60 days. It utilizes the 'Update' data model available in Splunk, specifically targeting events indicating an 'Installed' status from Microsoft Windows updates. The absence of timely updates is a critical concern for security operations centers (SOCs), as endpoints that remain unpatched are susceptible to known exploits and vulnerabilities. If an endpoint is compromised, it may show a pattern of neglecting updates deliberately, thereby allowing attackers to exploit outdated systems and potentially gain unauthorized access. This rule focuses on monitoring update statuses to ensure endpoints are regularly patched against emerging threats.
