What is DNS Filtering and How Does it work?

What is DNS Filtering and How Does it work?

DNS filtering is a cybersecurity technique that blocks access to malicious or unwanted websites by intercepting and inspecting DNS queries. It operates at the Domain Name System level, categorising websites based on content and cross-referencing against predefined policies. If a requested site violates policies, the DNS filter blocks access, preventing
