A DNS Filtering Policy is a network security mechanism that controls access to websites and online resources by filtering DNS queries. Instead of directly blocking IP addresses, it blocks or allows domain names (e.g., example.com) based on defined rules.
HOW IT WORKS:
Step 1:
Go to the desired cluster, in which you want to implement DNS Filtering Policy.
Step 2:
To create DNS Filter Policy go to policy under Profiles section. Click on the create policy to create a new policy.
Step 3:
Give a Profile name and Description, After that click on the Definitions.
Step 4:
Select the DNS server and then specify the whitelisted domains, which are the URLs allowed to be resolved through DNS.
(1) Ray DNS – Select this option if you want to use Ray's default DNS server. Choose the appropriate filtering level based on your requirement, and then click the Save button.
(2) Custom – Select this option if you are using a personal or local DNS server and provide the IP address of that DNS server.
