These queries generate events which can be used for a forensic investigation, so you can focus on fast response and remediation. See The LevelBlue Agent for more information.

12. Select an App Action.

    The options vary depending on the selected action type.

13. In the Length text box, specify the timespan that you want to use to identify a match for multiple occurrences. Enter the number in the text box, and then use the drop-down menu to select a value of seconds, minutes, or hours.

    This duration identifies the amount of time that transpires from the beginning to the end of the occurrence. If the number of occurrences is not met within this period, the rule is not a match.

Note: Your defined length and occurrences function together to specify the number of occurrences within a time period that will produce a match for the rule. For example, you can define a rule to trigger an alarm Alarms provide notification of an event or sequence of events that require attention or investigation. for an unauthorized access An incident-type categorization that may be a precursor to other actions or stages of an attack. attempt when a failed SSH Program to securely log into another computer over a network, execute commands in a remote machine, and move files from one machine to another through Secure Copy (SCP). login Log in (verb): Process in which an individual gains access to a computer system after providing sufficient credentials to authenticate their unique identity.
