Fix Recommendation

Edit the "named.conf" file.

Add the "transfers-out" sub-statement to the "options" statement block.

The value of the "transfers-out" will be based on organizational requirements needed to support DNS operations.

Restart the BIND 9.x process.

Check Contents

Verify the name server is configured to limit the number of concurrent client connections:

Inspect the "named.conf" file for the following:

options {
transfers-out 10;
};

If the "options" statement does not contain a "transfers-out" sub-statement, this is a finding.
