CIS 9.4 — Disable the HTTP Statistics Server

Profile Applicability

Authoritative Name Server Level 1
Caching Only Name Server Level 1

Description

Starting in BIND 9.5.0 there was a new statistics web server included, that is a useful debugging tool in a non-production environment. The HTTP server provide data in XML format about the condition of a BIND 9 server. The statistics server provides the same statistics that are available to the statistics-file dump. This server should be left disabled.

Rationale

A production name server should not have additional, unnecessary services running, as the additional services increases the risk of vulnerabilities.

Impact

Not specified.

Audit Procedure

Verify that there is NOT a statistics channel statement:

# grep statistics-channel $CONFIG_FILES

No output is expected and confirms that the HTTP service is not enabled.

Remediation

Remove the statistics-channel option from the configuration file.

Default Value

The HTTP server is disabled by default.

References

None listed in benchmark.
