SV-79125r1_rule OHS must have the HostnameLookups directive enabled.

Vulnerability discussion

Setting the "HostnameLookups" to "On" allows for more information to be logged in the event of an attack and subsequent investigation. This information can be added to other information gathered to narrow the attacker location. The DNS name can also be used for filtering access to the OHS hosted applications by denying particular types of hostnames.

Check content

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS//httpd.conf and every .conf file (e.g., ssl.conf) included in it with an editor. 2. Search for the "HostnameLookups" directive at the server, virtual host, and directory configuration scopes. 3. If the "HostnameLookups" directive is omitted or is not set to "On", this is a finding.

Fix text

1. Open $DOMAIN_HOME/config/fmwconfig/components/OHS//httpd.conf and every .conf file (e.g., ssl.conf) included in it with an editor. 2. Search for the "HostnameLookups" directive at the server, virtual host, and directory configuration scopes. 3. Set the "HostnameLookups" directive to "On", add the directive if it does not exist.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
