Fix Recommendation

Disable functions, ports, protocols, and services that are not approved.

- - - - -
Change the SQLNET.ora, LISTENER.ora, and TNSNAMES.ora files to reflect the proper use of ports, protocols, and services that are approved at the site.

If changes to the Listener are made, the files associated with the Listener must be reloaded by issuing the following commands at the Unix/Linux or Windows prompt.

Issue the command to verify what the current status is:
$ lsnrctl stat

Load the new file that was corrected to reflect site-specific requirements:
$ lsnrctl reload

Check the status again to verify that the changes have taken place:
$ lsnrctl stat

Check Contents

Review the database management system (DBMS) settings for unapproved functions, ports, protocols, and services.

If any are found, this is a finding.

In the Oracle database, the communications with the database and incoming requests are performed by the Oracle Listener. The Oracle Listener listens on a specific port or ports for connections to a specific database. The Oracle Listener has configuration files located in the $ORACLE_HOME/network/admin directory. To check the ports and protocols in use, go to that directory and review the SQLNET.ora, LISTENER.ora, and the TNSNAMES.ora. If protocols or ports are in use that are not authorized, this is a finding.
