Providing Conditions for First Time Occurrence

The First Time Occurrence algorithm detects activities or IP addresses and accounts that have not been observed before. For example, the first use of a transaction by an account. This algorithm identifies an entity's normal behavior and compares it to past behavior to detect the first time that a new transaction occurs. The First Time Occurrence violations stops occurringtriggering after the first time a transaction is detected. For What do you Want to Detect, choose under First Time Occurrence. For Choose the Features for Generating Behavior, based on the policy, select the attributes Unified Defense SIEM will use to learn normal behavior. Behavior profiles are generated on a combination of the selected features and the Criteria to Filter Events (Conditions). To detect when a user accesses a file that has not been accessed by anyone else in their peer group, build the baseline on the filename and use Conditions to specify the type of transaction in which the filename attribute should

, function (e) { // Prevent Chrome 76 and later from showing the mini-infobar e.preventDefault(); // Stash the event so it can be triggered later. window[
