System and method for interfacing with heterogeneous network data gathering tools
View Patent ↗A prevention-based network auditing system includes a plurality of heterogeneous information sources gathering information about the network. An audit server invokes the heterogeneous information sources via a uniform communications interface to gather information about the network, and converts the information gathered by the information sources into a normalized data format such as, for example, into XML (Extensible Markup Language). The converted information is then stored in an audit repository for security and regulatory policy assessment, network vulnerability analysis, report generation, and security improvement recommendations.
1. A method, comprising:
mapping dynamic addresses associated with network hosts to static identifiers associated with the network hosts;
receiving results from a scan of the network hosts in heterogeneous formats;
maintaining a reference map that maps an identifier of a test conducted by a first one of the network hosts to an identifier of a test conducted by a second one of the network hosts;
identifying semantically equivalent results from the scan, based, at least in part, on the reference map;
comparing at least a portion of the semantically equivalent results with a network policy to determine compliance with the network policy; and
maintaining a history of compliance for each of the network hosts based on the static identifiers.
2. The method of claim 1 , wherein at least one of the static identifiers is a static hostname associated with one of the network hosts.
3. The method of claim 1 , wherein at least one of the static identifiers is a media access control address associated with one of the network hosts.
4. The method of claim 1 , wherein the network hosts consist of active network hosts.
5. The method of claim 1 , wherein the network hosts consist of active network hosts identified by responses to address resolution protocol requests, and the responses comprise media access control addresses and Internet Protocol addresses associated with the active network hosts.
6. The method of claim 1 , wherein the results include a list of wireless access point devices and associated parameters for accessing one or more wireless networks, and a location for each of the wireless access points is determined.
7. The method of claim 1 , wherein:
the static identifiers comprise media access control addresses associated with at least one of the network hosts;
the network hosts consist of active network hosts identified by responses to address resolution protocol requests, and the responses identify the media access control addresses associated with the active network hosts.
8. Logic encoded in one or more non-transitory media that includes code for execution and, when executed by one or more processors, is operable to perform operations comprising:
mapping dynamic addresses associated with network hosts to static identifiers associated with the network hosts;
receiving results from a scan of the network hosts in heterogeneous formats;
maintaining a reference map that maps an identifier of a test conducted by a first one of the network hosts to an identifier of a test conducted by a second one of the network hosts;
identifying semantically equivalent results from the scan, based, at least in part, on the reference map;
comparing at least a portion of the semantically equivalent results with a network policy to determine compliance with the network policy; and
maintaining a history of compliance for each host based on the static identifiers.
9. The encoded logic of claim 8 , wherein at least one of the static identifiers is a static hostname associated with one of the network hosts.
10. The encoded logic of claim 8 , wherein at least one of the static identifiers is a media access control address associated with one of the network hosts.
11. The encoded logic of claim 8 , wherein the network hosts consist of active network hosts.
12. The encoded logic of claim 8 , wherein the network hosts consist of active network hosts identified by responses to address resolution protocol requests, and the responses comprise media access control addresses and Internet Protocol addresses associated with the active network hosts.
13. The encoded logic of claim 8 , wherein the results include a list of wireless access point devices and associated parameters for accessing one or more wireless networks, and a location for each of the wireless access points is determined.
14. The encoded logic of claim 8 , wherein:
the static identifiers comprise media access control addresses associated with at least one of the network hosts;
the network hosts consist of active network hosts identified by responses to address resolution protocol requests, and the responses identify the media access control addresses associated with the active network hosts.
15. A system, comprising:
one or more processors operable to execute instructions stored on a memory such that the one or more processors
map dynamic addresses associated with network hosts to static identifiers associated with the network hosts;
receive results from a scan of the network hosts in heterogeneous formats;
maintain a reference map that maps an identifier of a test conducted by a first one of the network hosts to an identifier of a test conducted by a second one of the network hosts;
identify semantically equivalent results from the scan, based, at least in part, on the reference map;
compare at least a portion of the semantically equivalent results with a network policy to determine compliance with the network policy; and
maintain a history of compliance for each of the network hosts based on the static identifiers.
16. The system of claim 15 , wherein at least one of the static identifiers is a static hostname associated with one of the network hosts.
17. The system of claim 15 , wherein at least one of the static identifiers is a media access control address associated with one of the network hosts.
18. The system of claim 15 , wherein the network hosts consist of active network hosts.
19. The system of claim 15 , wherein the network hosts consist of active network hosts identified by responses to address resolution protocol requests, and the responses comprise media access control addresses and Internet Protocol addresses associated with the active network hosts.
20. The system of claim 15 , wherein the results include a list of wireless access point devices and associated parameters for accessing one or more wireless networks, and a location for each of the wireless access points is determined.
21. The encoded logic of claim 8 , the operations further comprising:
recommending one or more rules for modifying the network policy, based, at least in part, on a severity meter set for each of the rules, the network hosts are scanned by different types of scanners for which meta-information is provided, and the meta-information relates to capabilities for each of the scanners and how each of the scanners maps to other related scanners that can perform similar testing operations.
