DoD STIGs – V-32411

Overview:

Title: The OS must limit privileges to change the DBMS software resident within software libraries (including privileged programs).

Vulnerability ID: V-32411

STIG ID:

IA Controls: None

Severity: medium

Description: When dealing with change control issues, it should be noted any changes to the hardware, software, and/or firmware components of the information system and/or application can potentially have significant effects on the overall security of the system.

If the application were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process.

This requirement is contingent upon the language in which the application is programmed, as many application architectures in use today incorporate their software libraries into and make them inseparable from their compiled distributions rendering them static and version dependant. However, this requirement does apply to applications with software libraries accessible and configurable as in the case of interpreted languages.

Accordingly, only qualified and authorized individuals shall be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications.

The DBMS software libraries contain the executables used by the DBMS to operate. Unauthorized access to the libraries can result in malicious alteration. This may in turn jeopardize data stored in the DBMS and/or operation of the host system.

Check Text: Review permissions that control access to the DBMS software libraries. The software library location may be determined from vendor documentation or service/process executable paths.

DBA accounts, the DBMS process account, the DBMS software installation/maintenance account, SA accounts if access by them is required for some operational level of support such as backups, and the host system itself require access. Any others should be scrutinized and a reason for access provided by the DBA. If accounts that are not required and authorized to have access to the software library location do have access, this is a finding.

Fix Text: Restrict access to the DBMS software libraries to accounts that require access based on job function.
