Abstract

A log entry is received at a streaming component of an enterprise threat detection (ETD) system from a real-time push application programming interface (API) associated with a backend computing system. The received log entry is parsed using a runtime parser associated with the streaming component into mapped data in an ETD format compatible with the ETD system. The mapped data is transferred to an ETD streaming project and enriched. The streaming component writes the enriched data into a database associated with the ETD system.

Claims

1. A computer-implemented method, comprising:

receiving a log entry at a streaming component of an enterprise threat detection (ETD) system from a real-time push application programming interface (API) associated with a backend computing system;

parsing the log entry using a runtime parser associated with the streaming component into mapped data in an ETD format compatible with the ETD system;

transferring the mapped data to an ETD streaming project for enrichment;

enriching the mapped data as enriched data; and

writing, using the streaming component, the enriched data into a database associated with the ETD system.

2. The computer-implemented method of claim 1, comprising receiving a log entry generated by application on the backend computing system at a kernel log writing component.

3. The computer-implemented method of claim 2, comprising the log writing component instructing the real-time push API to send the log entry to the streaming component.

4. The computer-implemented method of claim 1, comprising:

splitting the received log entry into elements; and

mapping the elements into the ETD format.

5. The computer-implemented method of claim 1, wherein parsing the received log entry includes the runtime parser using mapping information for mapping a format of the received log entry to the ETD format.

6. The computer-implemented method of claim 1, wherein enriching the mapped data includes at least one of normalizing the mapped data, pseudonymizing users, or incorporating at least one of user information, subnet information, or a MAC address.

7. The computer-implemented method of claim 1, comprising writing the enriched data from the ETD streaming project to the streaming component.

8. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

receiving a log entry at a streaming component of an enterprise threat detection (ETD) system from a real-time push application programming interface (API) associated with a backend computing system;

parsing the log entry using a runtime parser associated with the streaming component into mapped data in an ETD format compatible with the ETD system;

transferring the mapped data to an ETD streaming project for enrichment;

enriching the mapped data as enriched data; and

writing, using the streaming component, the enriched data into a database associated with the ETD system.

9. The non-transitory, computer-readable medium of claim 8, comprising one or more instructions to receive a log entry generated by application on the backend computing system at a kernel log writing component.

10. The non-transitory, computer-readable medium of claim 9, comprising one or more instructions for the log writing component to instruct the real-time push API to send the log entry to the streaming component.

11. The non-transitory, computer-readable medium of claim 8, comprising one or more instructions to:

split the received log entry into elements; and

map the elements into the ETD format.

12. The non-transitory, computer-readable medium of claim 8, wherein parsing the received log entry includes the runtime parser using mapping information for mapping a format of the received log entry to the ETD format.

13. The non-transitory, computer-readable medium of claim 8, wherein enriching the mapped data includes at least one of normalizing the mapped data, pseudonymizing users, or incorporating at least one of user information, subnet information, or a MAC address.

14. The non-transitory, computer-readable medium of claim 8, comprising one or more instructions to write the enriched data from the ETD streaming project to the streaming component.

15. A computer-implemented system, comprising:

a computer memory; and

a hardware processor interoperably coupled with the computer memory and configured to perform operations comprising;

receiving a log entry at a streaming component of an enterprise threat detection (ETD) system from a real-time push application programming interface (API) associated with a backend computing system;

parsing the log entry using a runtime parser associated with the streaming component into mapped data in an ETD format compatible with the ETD system;

transferring the mapped data to an ETD streaming project for enrichment;

enriching the mapped data as enriched data; and

writing, using the streaming component, the enriched data into a database associated with the ETD system.

16. The non-transitory, computer-readable medium of claim 15, further configured to:

receive a log entry generated by application on the backend computing system at a kernel log writing component; and

to permit the log writing component to instruct the real-time push API to send the log entry to the streaming component.

17. The non-transitory, computer-readable medium of claim 15, further configured to:

split the received log entry into elements; and

map the elements into the ETD format.

18. The non-transitory, computer-readable medium of claim 15, wherein parsing the received log entry includes the runtime parser using mapping information for mapping a format of the received log entry to the ETD format.

19. The non-transitory, computer-readable medium of claim 15, wherein enriching the mapped data includes at least one of normalizing the mapped data, pseudonymizing users, or incorporating at least one of user information, subnet information, or a MAC address.

20. The non-transitory, computer-readable medium of claim 15, further configured to write the enriched data from the ETD streaming project to the streaming component.
