The BIND 9.x server implementation must be configured with a channel to send audit records to a remote syslog.


Overview

Description
Protection of log data includes assuring log data is not accidentally lost or deleted. Backing up audit records to a different system or onto separate media than the system being audited on a defined frequency helps to assure, in the event of a catastrophic system failure, the audit records will be retained. This helps to ensure a compromise of the information system being audited does not also result in a compromise of the audit records.

Verify that the BIND 9.x server is configured to send audit logs to the syslog service.

NOTE: syslog and local file channel must be defined for every defined category.

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

logging {
channel {
syslog ;
};

category { ; };

If a logging channel is not defined for syslog, this is a finding.

If a category is not defined to send messages to the syslog channel, this is a finding.

Ensure audit records are forwarded to a remote server:

# grep "\*.\*" /etc/syslog.conf |grep "@" | grep -v "^#" (for syslog)
or:
# grep "\*.\*" /etc/rsyslog.conf | grep "@" | grep -v "^#" (for rsyslog)

If neither of these lines exist, this is a finding.
Fix Text (F-7801r283693_fix)
Configure the "logging" statement to send audit logs to the syslog daemon.

logging {
channel {
syslog ;
};
category { ; };
};

Note: It is recommended to use a local syslog facility (i.e. local0 -7) when configuring the syslog channel.

Restart the BIND 9.x process.

Configure the (r)syslog daemon to send audit logs to a remote server.
