The rule 'Okta Multiple Failed Requests to Access Applications' focuses on detecting potentially malicious activity involving multiple failed application access attempts in Okta. This is significant as it may indicate the reuse of stolen session cookies, a common tactic used in account takeovers. The detection leverages data from Okta logs, specifically monitoring policy evaluation and single sign-on (SSO) events. The rule is triggered when a user has a high ratio of failed requests (greater than 50%) to access multiple applications. By aggregating data based on user accounts, session identifiers, and client IP addresses, the rule assesses the sum of challenges and successful authentications, raising the alarm when suspicious patterns emerge. This allows organizations to identify possible attempts to bypass authentication mechanisms, thus preventing unauthorized access to sensitive applications and safeguarding valuable data, thereby mitigating significant security risks.
