Domain Name System (DNS) translates website names into IP addresses. DNS security involves:

DNS Risks

  • DNS hijacking - malicious redirection to fake websites
  • DNS spoofing - providing false DNS responses
  • DNS monitoring - tracking websites you visit
  • DNS blocking - preventing access to certain sites

DNS Protection Measures

  • Use secure DNS providers (Cloudflare 1.1.1.1, Quad9 9.9.9.9)
  • Enable DNS over HTTPS (DoH) or DNS over TLS (DoT)
  • Configure DNS filtering to block malicious domains
  • Regularly verify DNS settings
