No Windows Updates in a time frame

splApache-2.0from splunk/security_content

The following analytic identifies Windows endpoints that have not generated an event indicating a successful Windows update in the last 60 days. It leverages the 'Update' data model in Splunk, specifically looking for the latest 'Installed' status events from Microsoft Windows. This activity is significant for a SOC because endpoints that are not regularly patched are vulnerable to known exploits and security vulnerabilities. If confirmed malicious, this could indicate a compromised endpoint that is intentionally being kept unpatched, potentially allowing attackers to exploit unpatched vulnerabilities and gain unauthorized access or control.
