Abstract

Systems and methods are provided for automated retrieval, processing, and/or distribution of cyber-threat information using a cyber-threat device. Consistent with disclosed embodiments, the cyber-threat device may receive cyber-threat information in first formats from internal sources of cyber-threat information using an accessing component of the cyber-threat device. The cyber-threat device may receive cyber-threat information second formats from external sources of cyber-threat information using an accessing component of the cyber-threat device. The cyber-threat device may process the received cyber-threat information in the first formats and the second formats into a standard format using a processing component of the cyber-threat device. The cyber-threat device may provide the processed items of cyber-threat information to a distributor using a distributing component of the cyber-threat device. The cyber-threat device may automatically report information concerning the processed items of cyber-threat information to a device of a user with a reporting component of the cyber-threat device.

Claims

1. A method for automated retrieval, processing, and distribution of cyber-threat information from a plurality of sources using a network device, comprising:

receiving cyber-threat information in one or more first formats from at least one internal source of cyber-threat information using an accessing component of the network device;

receiving cyber-threat information in one or more second formats from at least one external source of cyber-threat information using the accessing component of the network device;

processing the received cyber-threat information in the one or more first formats and the one or more second formats into a standard format using a processing component of the network device, wherein the standard format comprises at least one data marking that indicates a categorization of the received cyber-threat information in the one or more first formats and the one or more second formats;

providing the processed cyber-threat information to a distributor using a distributing component of the network device; and

automatically reporting information concerning the processed cyber-threat information to a user device using a reporting component of the network device.

2. The method of claim 1, wherein the at least one internal source of cyber threat comprises at least one network component of an entity system, and the accessing component of the network device receives cyber-threat information in the one or more first formats through APIs exposed by the at least one network component.

3. The method of claim 2, wherein the at least one network component of the entity system comprises a plurality of network components, and the one or more first formats comprises a plurality of first formats.

4. The method of claim 2, wherein the at least one network component of the entity system comprises at least one of a firewall appliance, router, intrusion detection system, fraud detection system, email appliance, webserver, proxy server, or security incident and event manager.

5. The method of claim 2, wherein the at least one network component of the entity system comprises at least one of a host system providing an email client, antivirus software, or anti-malware detector.

6. The method of claim 2, wherein the cyber-threat information in the one or more first formats comprises at least one of a webserver log, an anti-spam log, an anti-virus log, an email delivery log, or a system log.

7. The method of claim 3, wherein the plurality of first formats comprises one or more of a Common Log Format, Combined Log Format, or PST file.

8. The method of claim 2, wherein the accessing component of the cyber-threat device implements one or more of a web service or a file system service to receive the cyber-threat information in the one or more first formats.

9. The method of claim 8, wherein the implemented one or more of a web service comprises one or more of JSON-WSP or SOAP-WSDL.

10. The method of claim 8, wherein the implemented one or more of a web service is implemented as a representational state transfer web service.

11. The method of claim 1, wherein the at least one external source of cyber-threat information comprises cyber-threat information generated by one or more of a commercial security provider, governmental regulatory agency, or governmental security agency.

12. The method of claim 2, wherein the network device implements the accessing component using a scripting language, and wherein the accessing component calling libraries correspond to the APIs exposed by the network components to receive cyber-threat information in the one or more first formats.

13. The method of claim 1, wherein the standard format comprises an extensible description of cyber-threat information specifying observables and context for cyber-threat information.

14. The method of claim 13, wherein the data markings include source information and handling restrictions for each item of the cyber-threat information in the one or more first formats and the one or more second formats.

15. The method of claim 1, wherein the processing component of the cyber-threat device applies exclusion criteria to determine acceptable cyber-threat information from the retrieved cyber-threat information in the one or more first formats and the retrieved cyber-threat information in the one or more second formats.

16. The method of claim 1, wherein the distributor exposes an API for receiving the processed cyber-threat information.

17. The method of claim 16, wherein the distributor receives the processed cyber-threat information using a web service.

18. The method of claim 1, wherein reporting component configuration information configures the reporting component with one or more of reporting targets, reporting criteria, or reporting frequencies.

19. The method of claim 18, wherein the reporting component configuration information configures the reporting component to automatically instruct one or more network components of the entity system to modify a network component configuration.

20. The method of claim 19, wherein automatically instructing one or more network components to update a network component configuration comprises instructing an email appliance to update a blacklist.

21. The method of claim 1, further comprising specifying one or more users authorized to access cyber-threat information, cyber-threat information that may be accessed, methods of access to cyber-threat information, or permissible uses of accessed items of cyber-threat information, by a policy engine of the network device.

22. The method of claim 1, wherein processing component configuration information of the processing component specifies:

one or more identification criteria for cyber-threat information in the one or more first formats and the one or more second formats or

one or more processing rules for cyber-threat information in the one or more first formats and the one or more second formats.

23. The method of claim 2, further comprising displaying a user interface on a device by a display component of the network device.

24. The method of claim 23, further comprising enabling, by the display component, direct access to the at least one network component without authorization.

25. The method of claim 23, further comprising enabling, by the user interface, configuring of one or more of the access component, processing component, distributing component, reporting component, or policy engine.

26. The method of claim 25, wherein configuring the policy engine comprises one or more of managing a policy for at least one source of cyber-threat information, category of item of cyber-threat information, or item of cyber-threat information.
