Check Text ( C-7803r283698_chk )
Verify that the BIND 9.x server is configured to retain at least 3 versions of the local log file.

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

logging {
channel local_file_channel {
file "path_name" versions 3;
};

If the "versions" variable is not defined, this is a finding.

If the "versions" variable is configured to retain less than 3 versions of the local log file, this is a finding.
Fix Text (F-7803r283699_fix)
Edit the "named.conf" file.

Add the "versions" variable to the end of the "file" sub statement in the channel statement.

Configure the "versions" sub statement to a number that is greater or equal to 3.

Restart the BIND 9.x process.
