Summary
This detection rule monitors for changes in user status within Cisco Duo, specifically when a user's two-factor authentication (2FA) status is modified to 'Bypass' from 'Active'. Utilizing Cisco Duo activity logs, the rule analyzes user update actions to identify such transitions. The importance of monitoring this status change lies in its potential implications for account security; bypassing 2FA reduces the robustness of authentication, creating opportunities for unauthorized access. The rule targets an insider threat or account compromise scenarios that may go unnoticed without prompt detection. The alerting mechanism aids Security Operations Center (SOC) teams in swiftly investigating such events, thereby facilitating rapid responses to mitigate risk from credential-based attacks. The rule ensures that any instance of a user being set to bypass multifactor authentication is highlighted for further scrutiny, allowing security teams to maintain oversight over sensitive account transactions and uphold stringent security measures.
