A system and method for providing distributed security of a network. Several device profilers are placed at different locations of a network to assess vulnerabilities from different perspectives. The device profiler identifies the hosts on the network, and characteristics such as operating system and applications running on the hosts. The device profiler traverses a vulnerability tree having nodes representative of characteristics of the hosts, each node having an associated set of potential vulnerabilities. Verification rules can verify the potential vulnerabilities. A centralized correlation server, at a centrally accessible location in the network, stores the determined vulnerabilities of the network and associates the determined vulnerabilities with attack signatures. Traffic monitors access the attack signatures and monitor network traffic for attacks against the determined vulnerabilities.

There is provided a sentence module that handles pronouns in sentences. Each pronoun is replaced by one or more nouns. These replaced nouns are used to form statements that populate the structured representation, in order to produce precise answers to queries, as part of a search engine application.

Natural language based search engine for handling pronouns and methods of use therefor

There is provided a search engine or other electronic search application that receives an inputted query in natural language. The search engine then analyzes the query in accordance with the syntactic relationships of the natural language in which it was presented, weights the syntactic relationships, and generates a result to the query as output, corresponding to the syntactic relationship of the greatest weight. The outputted result is typically an answer, in the form of a sentence or a phrase, along with the document from which the sentence or phrase is taken, including a hypertext link for the document.
