Information
The Security Support Structure is a security control function or service provided by an external system or application. An example of this would be a Windows domain controller that provides identification and authentication that can be used by other systems to control access. The associated risk of a DBMS installed on a system that provides security support is significantly higher than when installed on separate systems. In cases where the DBMS is dedicated to local support of a security support function (e.g. a directory service), separation may not be possible.
Solution
Either move the DBMS installation to a dedicated host system or move the directory or security services to another host system.
A dedicated host system in this case refers to an instance of the operating system at a minimum.
The operating system may reside on a virtual host machine where supported by the DBMS vendor.
