Techopedia Explains Content Filtering

Content filtering works by matching strings of characters. When the strings match, the content is not allowed through. Content filters are often part of Internet firewalls. In such a usage content filtering is serving a security purpose, but content filtering is also used to implement company policies related to information system usage. For example, it’s common to filter websites containing pornographic materials or social-networking sites unrelated to work.
