Vulnerability discussion

Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions).It is detrimental for software products to provide, or install by default, functionality exceeding requirements or mission objectives. DBMSs must adhere to the principles of least functionality by providing only essential capabilities.

Check content

Review the list of components and features installed with the database. If unused components are installed and are not documented and authorized, this is a finding. RPM can also be used to check to see what is installed: yum list installed | grep ppas This returns EDB database packages that have been installed. If any packages displayed by this command are not being used, this is a finding.

Fix text

If any components are required for operation of applications that will be accessing the DBMS, include them in the system documentation. To uninstall and unused package (using ppas-odbc-devel-09.03.0400.02-1.rhel7.x86_64 as an example), execute the following command as root: yum erase -y ppas-odbc-devel-09.03.0400.02-1.rhel7.x86_64

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.
