Vulnerability discussion

Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default or selected for installation by an administrator, may not be necessary to support essential organizational operations (e.g., key missions, functions).Applications must adhere to the principles of least functionality by providing only essential capabilities. Unused and unnecessary SQL Server components increase the number of available attack vectors. By minimizing the services and applications installed on the system, the number of potential vulnerabilities is reduced.The SQL Server Replication software component must be removed from SQL Server if it is unused.

Check content

If the SQL Server Replication feature is used and satisfies organizational requirements, this is not a finding. In SQL Server Management Studio, Object Explorer, expand the instance. Right-click Replication >> New >> Publication. If the Publication Wizard appears, with no error message, this is a finding. Right-click Replication >> New >> Subscription. If the Subscription Wizard appears, with no error message, this is a finding.

Fix text

Either using the Start menu or via the command "control.exe", open the Windows Control Panel. Open Programs and Features. Double-click on Microsoft SQL Server 2014. In the dialog box that appears, select Remove. Wait for the Remove wizard to appear. Select the relevant SQL Server instance; click Next. Select SQL Server Replication; click Next. Follow the remaining prompts, to remove SQL Server Replication from SQL Server.

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.
