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:
receiving network scan results from information sources in heterogeneous formats;
converting the network scan results into structurally normalized scan results using a plurality of first tags and a second tag nested in the first tags, the first tags indicating a test, the second tag indicating a result of the test;
identifying semantically equivalent network scan results in the structurally normalized scan results; and
comparing at least a portion of the semantically equivalent network scan results with a network policy to determine a compliance with the network policy.
2. The method of claim 1 , wherein the network scan 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.
3. The method of claim 1 , further comprising
generating a remediation task for a violation of the network policy.
4. The method of claim 1 , further comprising
generating a remediation task for a violation of the network policy, wherein the remediation task identifies the violation by a severity and an address of a host associated with the violation.
5. The method of claim 1 , wherein the identifying the semantically equivalent network scan results comprises associating a symbolic reference with at least two of the information sources in a reference map.
