The 'Cisco Duo Policy Allow Old Java' detection analytic monitors for changes in Cisco Duo policies that potentially allow outdated Java versions, presenting significant security risks. It specifically tracks when a policy modification is made such that the 'java_remediation' setting is set to 'no remediation', indicating the absence of enforcement against older Java versions. This rule searches Duo administrator logs for such policy actions and aggregates relevant contextual data, including the user involved, admin email, and action performed, aiding detection for a Security Operations Center (SOC). The risk posed by failing to restrict outdated Java can expose systems to vulnerabilities and exploitation attempts; thus, this detection is crucial for the quick identification and response to such policy alterations to mitigate possible threats efficiently.
