Implementing web content filtering
- URL filtering. This method involves blocking or allowing access to specific websites based on their URLs. An administrator maintains a list of approved or restricted URLs, and the filtering system checks each requested URL against this list.
- Keyword filtering. In keyword filtering, specific words or phrases are identified as forbidden. The filtering system scans the content of web pages or search queries for these keywords and blocks access to any page containing them.
- Category filtering. Websites are categorized into different groups based on their content, like news, social media, gambling, entertainment, adult content, etc. The filtering system then allows or blocks access to entire categories of websites based on predefined rules.
