Patent ID: 7613766

Claim:
A method for linguistic analysis of local area network (LAN) data sources and wide area network (WAN) communications communicated on the LAN which is coupled to the WAN, said method comprising: establishing on a server communicatively coupled to the LAN a hierarchical plurality of pre-requisite triggers; initializing an Avoid Evaluation Of This Trigger (AEOTT) rating for one of the plurality of pre-requisite triggers; resolving the one of a plurality of pre-requisite triggers for a first of a plurality of data sets associated with one of the data sources or with a WAN communication communicated on said LAN; determining whether resolving the pre-requisite trigger caused an early exit; if resolving the pre-requisite trigger caused an early exit, modifying the AEOTT rating by decreasing the AEOTT rating; if resolving the pre-requisite trigger did not cause an early exit, modifying the AEOTT rating by increasing the AEOTT rating; resolving the plurality of pre-requisite triggers for subsequent ones of the plurality of data sets in an order based on the modified AEOTT rating; and based on said resolving steps, performing a predetermined action selected from the group consisting of blocking LAN access to or from a URL associated with the WAN communication and communicated on the LAN, alerting an administrator about the WAN communication communicated on the LAN or about the one of the data sources, and logging data about the WAN communication communicated on the LAN or about the one of the data sources.
