The detection rule 'Windows IIS Components Module Failed to Load' identifies instances when a DLL associated with IIS modules fails to load, indicated by EventCode 2282 in Windows Application event logs. This could signal a misconfiguration or an attempted tampering with IIS components, potentially leading to service disruptions or exploitation risks by attackers. Frequent failures often require immediate investigation to ascertain their legitimacy, as they can open up avenues for security breaches. By monitoring these failures, organizations can proactively address vulnerabilities before they escalate into significant security incidents. The analytic requires IIS to be installed and log collection for Application events to be operational. False positives may arise until all associated module issues are resolved or examined.
