Abstract

A computer-implemented method generates a trigger registration for a selected triggering type. The generated trigger registration is stored in a triggering persistency. A received event from an event persistency is analyzed and data associated with the analyzed event is compared with the triggering persistency. Based on the comparison and using a pattern execution framework, an enterprise threat detection (ETD) pattern is processed to perform actions responsive to the received event.

First claim

What is claimed:

1. A computer-implemented method, comprising:
generating a trigger registration for a selected triggering type;
storing the generated trigger registration in a triggering persistency;
analyzing a received event from an event persistency;
generating a comparison of forensic data associated with the analyzed event with the triggering persistency;
based on the comparison, processing, using a pattern execution framework, an enterprise threat detection (ETD) pattern to provide for display in realtime an alert associated with the ETD pattern, wherein the ETD pattern contains paths connected over references and each path comprising subsets representing conditions defining triggers of the alert; and
transmitting a pattern identification of the ETD pattern to a dispatcher that creates a plurality of triggering threads corresponding to the ETD pattern, the plurality of triggering threads being executed to complete processing of the ETD pattern and ending without returning to the dispatcher.

2. The computer-implemented method of claim 1 , wherein the triggering type includes one of the group consisting of by event and by pattern.

3. The computer-implemented method of claim 1 , wherein the trigger registration is stored in a triggering persistency registration list.

4. The computer-implemented method of claim 3 , comprising determining that the data associated with the analyzed event matches registered content or one or more semantic value trigger registrations in the triggering persistency registration list.

5. The computer-implemented method of claim 1 , comprising:
instantiating a processing thread to process the ETD pattern; and
delegating the processing of the ETD pattern from the processing thread to the pattern execution framework.

6. The computer-implemented method of claim 1 , comprising determining that execution of the ETD pattern generates an additional event.

7. The computer-implemented method of claim 6 , comprising determining whether a triggering registration for the additional event exists in the triggering persistency.

8. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
generating a trigger registration for a selected triggering type;
storing the generated trigger registration in a triggering persistency;
analyzing a received event from an event persistency;
generating a comparison of forensic data associated with the analyzed event with the triggering persistency;
based on the comparison, processing, using a pattern execution framework, an enterprise threat detection (ETD) pattern to provide for display in realtime an alert associated with the ETD pattern, wherein the ETD pattern contains paths connected over references and each path comprising subsets representing conditions defining triggers of the alert; and
transmitting a pattern identification of the ETD pattern to a dispatcher that creates a plurality of triggering threads corresponding to the ETD pattern, the plurality of triggering threads being executed to complete processing of the ETD pattern and ending without returning to the dispatcher.

9. The non-transitory, computer-readable medium of claim 8 , wherein the triggering type includes one of the group consisting of by event and by pattern.

10. The non-transitory, computer-readable medium of claim 8 , wherein the trigger registration is stored in a triggering persistency registration list.

11. The non-transitory, computer-readable medium of claim 10 , comprising one or more instructions to determine that the data associated with the analyzed event matches registered content or one or more semantic value trigger registrations in the triggering persistency registration list.

12. The non-transitory, computer-readable medium of claim 8 , comprising one or more instructions to:
instantiate a processing thread to process the ETD pattern; and
delegate the processing of the ETD pattern from the processing thread to the pattern execution framework.

13. The non-transitory, computer-readable medium of claim 8 , comprising one or more instructions to determine that execution of the ETD pattern generates an additional event.

14. The non-transitory, computer-readable medium of claim 13 , comprising one or more instructions to determine whether a triggering registration for the additional event exists in the triggering persistency.

15. A computer-implemented system, comprising:
a hardware processor interoperably coupled with a computer memory and configured to perform operations comprising:
generating a trigger registration for a selected triggering type;
storing the generated trigger registration in a triggering persistency;
analyzing a received event from an event persistency;
generating a comparison of forensic data associated with the analyzed event with the triggering persistency;
based on the comparison, processing, using a pattern execution framework, an enterprise threat detection (ETD) pattern to provide for display in realtime an alert associated with the ETD pattern, wherein the ETD pattern contains paths connected over references and each path comprising subsets representing conditions defining triggers of the alert; and
transmitting a pattern identification of the ETD pattern to a dispatcher that creates a plurality of triggering threads corresponding to the ETD pattern, the plurality of triggering threads being executed to complete processing of the ETD pattern and ending without returning to the dispatcher.

16. The computer-implemented system of claim 15 , wherein the triggering type includes one of the group consisting of by event and by pattern.

17. The computer-implemented system of claim 15 , wherein the trigger registration is stored in a triggering persistency registration list.

18. The computer-implemented system of claim 17 , configured to determine that the data associated with the analyzed event matches registered content or one or more semantic value trigger registrations in the triggering persistency registration list.

19. The computer-implemented system of claim 15 , configured to:
instantiate a processing thread to process the ETD pattern; and
delegate the processing of the ETD pattern from the processing thread to the pattern execution framework.

20. The computer-implemented system of claim 15 , configured to:
determine that execution of the ETD pattern generates an additional event; and
determine whether a triggering registration for the additional event exists in the triggering persistency.
