If you want to analyze the data
Use the icon to change the alarms view, which is by default Alarms by Intent.
The icon accesses these options:
- Alarms by Intent: This view is a bubble graph that provides a graphical representation of alarms by intent.
- Count / Time: The Count/Time view is a graph that provides a graphical representation of the number of
alarmsin a period of time.
- MITRE ATT&CK: The MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge) is a framework for understanding attackers' behaviors and actions.
- Alarm Strategies by Intent: This view is a table that provides a representation of alarms strategies by intent.
Important: The period of time is mapped with the timestamp_occurred field. This field can be overwritten by the current sensor UTC timestamp if, when processing events, a delay is detected up to 15 minutes or the timestamp_occurred field is not provided.
The MITRE ATT&CK View
USM Anywhere and AT&T Alien Labs™ Open Threat Exchange® (OTX™) include MITRE ATT&CK information. The alarms view incorporates a table with tactics and techniques to describe adversarial actions and behaviors. Techniques are specific actions an attacker might take and tactics are phases of attacker behavior. This view includes the alarms mapping to their corresponding ATT&CK techniques and helps you to understand the context and the scope of an attack. See MITRE ATT&CK for more information.
The headers of the table are the 11 ATT&CK tactics, and each tactic has numerous techniques, which are the rows. The tooltips match the identification (ID) technique provided by MITRE ATT&CK. Some techniques display in several tactics. If you click in one of the techniques, the specific filters are added and the list shows the result.
USM Anywhere includes MITRE ATT&CK Dashboard to display MITRE ATT&CK information.
The Alarm Strategies by Intent view displays a table that lists the purposes of the alarm. The table headers represent the intent of the alarms. The table rows display the strategies.
