Using Browser Protection and Web Filtering Authorize and prohibit sites by URL or domain NOTE: By authorizing a site, the browser protection service ignores the safety rating for that site. Users can access authorized sites even if threats have been reported on these sites and they have a safety rating of red. Users can also access unsafe downloads and phishing pages on authorized sites. It is important to exercise caution when adding authorized sites to an Exceptions list. How site patterns work The Exceptions list uses site patterns to specify a range of sites that are authorized or prohibited. This enables you to authorize or prohibit a particular domain or a range of similar sites without entering each URL separately. When a client computer attempts to navigate to a site, the browser protection service checks whether the URL matches any site patterns configured in the Exceptions list. It uses specific criteria to determine a match. A site pattern consists of a URL or partial URL, which the browser protection service interprets as two distinct sections: domain and path. Site pattern: www.mcafee.com/us/enterprise http:// www.mcafee.com This is the domain. The domain consists of two parts: • Protocol. In this case: http:// • Internet domain. In this case: www.mcafee.com Domain information is matched from the end. A matching URL's domain must end with the site pattern's domain. The protocol can vary. These domains match: • http:// ftp.mcafee.com • https://mcafee.com • http://www.info.mcafee.com These domains do not match: • http:// www.mcafee.downloads.com • http://mcafee.net • http://www.mcafeeasap.com • http://us.mcafee.com /us/enterprise This is the path. The path includes everything that follows the / after the domain. Path information is matched from the beginning. A matching URL's path must begin with the site pattern's path. These paths match: • /us/enterpriseproducts • /us/enterprise/products/security These paths do not match: • /emea/enterprise • /info/us/enterprise Site patterns must be at last six characters in length, and they do not accept wildcard characters. The browser protection service does not check for matches in the middle or end of URLs. 114 McAfee Total Protection Service Product Guide Matches • http://www.info.mcafee.com • http://mcafee.com Does not match • http://www.mcafeeasap.com • http://salesmcafee.com
