A Guide to Internet Blockers and Filters
Features to Consider
Internet filtering software packages come in all shapes and sizes. Some packages over-block or under-block content, and what’s good for one family may not be suitable for another. Parents should consider an Internet filter that:
Parents should choose user-friendly programs that are easy to install and easy to use. Purchasing a complicated package that has all the latest bells and whistles defeats the purpose when parents can’t manipulate or understand all the great features. |
Types of Internet Filters
Internet filtering software uses algorithms, or patterns, that check website addresses and pages for images or words that depict graphic violence, have sexual content, contain racial slurs or epithets (or other related hate content), and other content deemed inappropriate by parents (political web sites, gambling and alcohol-related sites). There are three distinct types of Internet filters. Black List Filters Black list filters are the most popular types of Internet blocking software. A website is added to a black list (“bad” list) that keeps track of content with objectionable words and images. When a user tries to access the website address on their browser, the software compares the address to the addresses on the list. If there is a match, the users are denied access to the requested website. White List Filters White list filters allow access only to “good” sites on the list while denying access to websites not on the list. White list filters are the most restrictive blockers. Keyword or Content Filters Keyword or content lists scan websites for the presence of specific words, phrases, or images that appear on the restricted list. Access to a website is denied if the keyword or content matches any words on the list. Because of the specificity of the filter, these programs often deny access to websites that have acceptable content. Content Rating Systems Webmasters provide a classification of a website based on its content. Website classifications are voluntary and are based on the web developer’s description of their online content. |
Which Package Do I Want?
Before purchasing any Internet filtering packages, find out what levels of protection your Internet Service Provider (ISP) provides, and decide what your family needs. Things to take into consideration are the ages of the users, defining what is and what is not acceptable, and deciding on the level of blocking needed. Some ISPs build filtering into their software programs so that you won’t need to spend an extra dime. ISPs such as Time Warner’s Roadrunner, AOL., Earthlink, and MSN offer free software packages to subscribers with basic firewall capabilities. All you need to do is set up the software and determine the appropriate levels of access for each family member. For example, Roadrunner offers the Computer Associates’ eTrust® Internet Security Suite ($69.95) which comes with antivirus, anti-spam, pop-up blocking and firewall capabilities. The program also regularly downloads and installs automatic updates. The package is free to Time Warner Internet subscribers, and can be downloaded from http://content.rr.com/rdrun/feat_security.htm. AOL also provides parental control software which requires its young members to get parent-approved screen names. If your ISP does not offer effective filtering programs, consider checking out the products that have been tested and evaluated by the Consumers Union, publisher of the Consumer Reports Guides. Their website provides a great list of effective software filters. Among their picks are:
It’s important to remember that while Internet filters are effective in limiting what children see and do online, these tools are not foolproof, and hackers are always on the prowl to break the tool. Parents should take an active role in monitoring online activity to let children know which behaviors are or are not appropriate while web surfing. Communication coupled with these external programs is the best defense parents can have towards protecting their children online. |
