Definition
Web content filtering is a technology or process of restricting or controlling access to specific websites or web pages based on predefined rules. It is widespread in schools, businesses, and individuals who want to manage internet usage.
Implementing Web Content Filtering
- URL filtering: It involves allowing or blocking access to specific websites based on the URLs. An administrator curates a list of permitted or restricted URLs, which the filtering system uses to verify each URL request.
- Keyword filtering: It involves identifying forbidden words or phrases. The filtering system scans the web page content or search queries for these keywords and blocks access to any page that contains them.
- Category filtering: It involves allowing or blocking access to different categories of websites based on predefined criteria. Websites are usually categorized into different groups based on their content, such as social media, news, gambling, entertainment, etc.
