Definition
URL filtering is a technique for controlling or restricting access to websites based on their Uniform Resource Locators (URLs). It involves analyzing URLs and applying predefined rules to allow or block access to specific websites.
This technique is common in schools and organizations, where internet access is regulated to ensure security or apply content restrictions.
Examples of URL Filtering
- Blocklists and allowlists: Block lists and allow lists can include URLs based on their addresses.
- Categories: Access or restrictions can be applied to specific website categories, such as gambling, social media, news, adult content, or entertainment.
- Keywords and phrases: URL filtering can be applied based on specific addresses, webpages, or metadata keywords.
URL Filtering Use Cases
- Parental controls: Most parental control software programs or routers use URL filtering to restrict children’s access to age-appropriate websites. For example, parents can filter out explicit content, gambling, violence, and other inappropriate content.
- Workplace: Many organizations use URL filtering to manage and regulate employee internet usage.
