BIND-9X-001053 - The BIND 9.x server implementation must be configured to use only approved ports and protocols.


In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable or restrict unused or unnecessary physical and logical ports/protocols on information systems.

Applications are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations.

To support the requirements and principles of least functionality, the application must support the organizational requirements by providing only essential capabilities and limiting the use of ports, protocols, and/or services.


Edit the 'named.conf' file.

Add the following line to the 'options' statement:

listen-on port 53 { <ip_address>; };

Replace '<ip_address>' with the IP of the name server.

Restart the BIND 9.x process.
