Abstract

A transfer of master data is executed in a backend computing system. The master data includes user data and system data. The transfer of master data includes receiving user data associated with a particular user identifier in the backend computing system, transferring the received user data to an event stream processor, receiving system data associated with a particular log providing computing system in the backend computing system, transferring the received user data to the event stream processor, and executing a transfer of log data associated with logs of computing systems connected to the backend computing system.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
executing, by a computer, a transfer of master data in a backend computing system, wherein the master data includes user data and system data, and wherein the transfer of master data comprises:
receiving, by the computer and from a user management system or an identity management system, user data associated with a particular user id in the backend computing system;
transferring, by the computer, the received user data to an event stream processor (ESP);
receiving, by the computer, system data associated with a particular log providing computing system in the backend computing system; and
after transferring the received user data to the ESP, transferring, by the computer, the received system data to the ESP; and
after executing the transfer of master data, executing, by the computer, a transfer of log data associated with logs of computing systems connected to the backend computing system,

wherein one or more log entries of the transferred log data are enriched to include the particular user id, and the enriched one or more log entries are stored in a threat detection system and used by the threat detection system to identify one or more security threats associated with the computing systems.

2. The method of claim 1 , wherein, for the system data, the master data is received from system context data associated with a particular computing system connected to the backend computing system as determined by a software application executing on the backend computing system or manual maintenance data related to a particular system context.

3. The method of claim 1 , wherein the user data is associated with a single individual or a common identification associated with multiple individuals.

4. The method of claim 1 , comprising:
if determined that a user context associated with the particular user id is not available to the ESP, creating a new user context associated with the particular user id; and
if determined that a user context associated with the particular user id is available to the ESP, updating the user context associated with the particular user id.

5. The method of claim 1 , comprising:
if determined that a system context associated with the particular log providing computing system is not available to the ESP, creating a new system context associated with the particular log providing computing system; and
if determined that a system context associated with the particular log providing computing system is available to the ESP, updating the system context associated with the particular log providing computing system.

6. The method of claim 1 , wherein the transfer of log data comprises:
reading log data from a particular log associated with a particular computing system, wherein the log data is read starting with the latest timestamp;
transferring read log data to the ESP, wherein the read log data is transformed into a normalized format prior to transfer; and
enriching each log entry of the transferred log data.

7. The method of claim 6 , wherein the enrichment of each particular log entry comprises:
attempting to read a user context for a particular user id associated with the particular log entry;
if a user context for the particular user id is found within the backend computing system, writing into the particular log a user context id associated with the user context;
if a user context for the particular user id is not found within the backend computing system, creating a new user context within the backend computing system and writing into the particular log a user context id associated with the new user context;
removing the original user id from the particular log entry; and
writing a revised log entry into the backend computing system.

8. A non-transitory, computer-readable medium storing computer-readable instructions, the instructions executable by a computer and configured to:
execute a transfer of master data in a backend computing system, wherein the master data includes user data and system data, and wherein the transfer of master data comprises:
receive, from a user management system or an identity management system, user data associated with a particular user id in the backend computing system;
transfer the received user data to an event stream processor (ESP);
receive system data associated with a particular log providing computing system in the backend computing system; and
after transferring the received user data to the ESP, transfer the received system data to the ESP; and

after executing the transfer of master data, execute a transfer of log data associated with logs of computing systems connected to the backend computing system, wherein one or more log entries of the transferred log data are enriched to include the particular user id, and the enriched one or more log entries are stored in a threat detection system and used by the threat detection system to identify one or more security threats associated with the computing systems.

9. The non-transitory, computer-readable medium of claim 8 , wherein, for the user data, the master data is received from a user management system or an identity management system, and wherein, for the system data, the master data is received from system context data associated with a particular computing system connected to the backend computing system as determined by a software application executing on the backend computing system or manual maintenance data related to a particular system context.

10. The non-transitory, computer-readable medium of claim 8 , wherein the user data is associated with a single individual or a common identification associated with multiple individuals.

11. The non-transitory, computer-readable medium of claim 8 , the instructions further configured to:
if determined that a user context associated with the particular user id is not available to the ESP, create a new user context associated with the particular user id; and
if determined that a user context associated with the particular user id is available to the ESP, update the user context associated with the particular user id.

12. The non-transitory, computer-readable medium of claim 8 , the instructions further configured to:
if determined that a system context associated with the particular log providing computing system is not available to the ESP, create a new system context associated with the particular log providing computing system; and
if determined that a system context associated with the particular log providing computing system is available to the ESP, update the system context associated with the particular log providing computing system.

13. The non-transitory, computer-readable medium of claim 8 , wherein the transfer of log data comprises:
reading log data from a particular log associated with a particular computing system, wherein the log data is read starting with the latest timestamp;
transferring read log data to the ESP, wherein the read log data is transformed into a normalized format prior to transfer; and
enriching each log entry of the transferred log data.

14. The non-transitory, computer-readable medium of claim 13 , wherein the enrichment of each particular log entry comprises:
attempting to read a user context for a particular user id associated with the particular log entry;
if a user context for the particular user id is found within the backend computing system, writing into the particular log a user context id associated with the user context;
if a user context for the particular user id is not found within the backend computing system, creating a new us
