Potential false positivesedit
SAML Provider could be updated by a system administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment. SAML Provider updates by unfamiliar users should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
