Using DNS Filtering to Block Websites

DNS filtering is a powerful method for blocking access to unwanted websites by intercepting and redirecting domain name system (DNS) requests to predefined categories of websites.

DNS filtering works by analyzing DNS requests made by users when attempting to access websites.

When a user tries to visit a specific URL, the DNS filtering system checks the requested domain against a database of categorized websites and determines whether it falls within a restricted category, such as:

  • Social media
  • Gambling
  • Malware-infected sites

If the website is flagged as unwanted, the DNS filtering system blocks the DNS resolution process, preventing the user from accessing the site and displaying a block page.

DNS filtering operates at the network level, meaning that it applies to all devices connected to the organization’s network, including company-owned devices, guest devices, and IoT devices, ensuring consistent enforcement of internet usage policies across the entire network infrastructure. 

Configuring DNS to Block Specific Categories of Websites

Administrators can create DNS filtering rules based on categories such as adult content/adult websites, gambling, social media, or malware-infected sites, using categorized lists provided by DNS filtering providers or customizing them according to the organization’s specific requirements.

Blocking Websites Through Network Security Measures

Network security measures can be used to block access to specific websites or categories of websites. This is achieved through:

  • Firewall rules: These define what traffic is allowed to enter or leave the network.
  • Web filtering appliances: Dedicated devices that analyze and filter web traffic based on pre-defined criteria.
