Internet Filters and Parental Control Software

Internet filters and parental control software fall under the category of content control software, also called content filtering software or web filtering software. These programs are designed to block or restrict access to certain types of computer content that the reader or parents of readers wish to control accessibility to. For example, content over the Internet, such as that found in spam email or pornographic websites, may be blocked to protect the computer from viruses, worms, and malware, or to protect minors from accessing material deemed objectionable or inappropriate for those under 18 years of age.

 

There are many types of filters available, including browser based filters, email filters, and search engine filters to name a few.  Nearly all of parental control software uses passwords or other authentication in order to inhibit unauthorized users from changing or disabling the restrictions. However, content control software is not fool proof; there are ways to bypass control settings.
