SYSTEMS AND METHODS FOR ENFORCING POLICIES TO BLOCK SEARCH ENGINE QUERIES FOR WEB-BASED PROXY SITES
In embodiments of the present invention improved capabilities are described for systems and methods that enforce policies with respect to proxy communications.
1 . A computer program product embodied in a computer readable medium that, when executing on one or more computers, performs the steps of:
intercepting a universal resource locator (URL) request from a client computing facility;
interpreting terms in the URL to identify that the URL was produced by a search engine in response to a search; and
interpreting the terms in the URL to identify that the search was directed towards locating a blocked category of website.
2 . The computer program product of claim 1 , further comprising: blocking the website.
3 . The computer program product of claim 1 , further comprising: allowing connection to the website.
4 . The computer program product of claim 1 , further comprising: sending an alert and allowing connection to the website.
5 . The computer program product of claim 1 , further comprising: performing a content analysis on a website associated with the URL to confirm that it is of the blocked type of website.
6 . The computer program product of claim 5 , further comprising blocking the website.
7 . The computer program product of claim 5 , further comprising allowing connection to the website.
8 . The computer program product of claim 5 , further comprising sending an alert and allowing connection to the website.
9 . A computer program product embodied in a computer readable medium that, when executing on one or more computers, performs the steps of:
intercepting a universal resource locator (URL) request from a client computing facility;
interpreting characters in the URL to identify that the URL was produced by a search engine in response to a search; and
interpreting the characters in the URL to identify that the search was directed towards locating a blocked category of website.
10 . A computer program product embodied in a computer readable medium that, when executing on one or more computers, blocks proxy website interactions by performing the steps of:
intercepting a universal resource locator (URL) request from a client computing facility;
analyzing the characters that comprise the URL; and
in response to a finding that the URL was produced by a search engine software program and directed to a search request for a proxy site, blocking access to search results based on the URL.
11 . The computer program product of claim 10 , wherein the step of analyzing the characters that comprise the URL involves detecting keywords in the URL and comparing the keywords to a database of suspicious keywords to find a match.
12 . The computer program product of claim 10 , wherein the step of analyzing the characters that comprise the URL involves detecting strings of characters that match a string of characters typical of a search engine.
13 . The computer program product of claim 10 , wherein the step of analyzing the characters that comprise the URL involves detecting strings of characters that match a string of characters typical of a proxy website identification search.
14 . The computer program product of claim 10 , wherein the step of analyzing the characters that comprise the URL involves detecting regular expressions that match a regular expression typical of a search engine.
15 . The computer program product of claim 14 , wherein the regular expression involves prefix matching.
16 . The computer program product of claim 14 , wherein the regular expression involves suffix matching.
17 . The computer program product of claim 14 , wherein the regular expression involves wildcard matching.
18 . The computer program product of claim 14 , wherein the regular expression involves substitution matching.
19 . The computer program product of claim 10 , wherein the step of analyzing the characters that comprise the URL is performed on the client computing facility.
20 . The computer program product of claim 10 , wherein the step of analyzing the characters that comprise the URL is performed on a network resource associated with the client computing facility.
