Title: Databases employed to write data to portable digital media must use cryptographic mechanisms to protect and restrict access to information on portable digital media.
Vulnerability ID: V-32489
IA Controls: None
Description: When data is written to portable digital media, such as thumb drives, floppy diskettes, compact disks, magnetic tape, etc., there is risk of data loss.
An organizational assessment of risk guides the selection of media and associated information contained on that media requiring restricted access.
Organizations need to document in policy and procedures, the media requiring restricted access, individuals authorized to access the media, and the specific measures taken to restrict access. Fewer protection measures are needed for media containing information determined by the organization to be in the public domain, to be publicly releasable, or to have limited or no adverse impact if accessed by other than authorized personnel.
In these situations, it is assumed the physical access controls where the media resides provide adequate protection. The employment of cryptography is at the discretion of the information owner/steward.
The selection of the cryptographic mechanisms used is based upon maintaining the confidentiality and integrity of the information.
The strength of mechanisms is commensurate with the classification and sensitivity of the information.
When the organization has determined the risk warrants it, data written to portable digital media must be encrypted. When information written to digital media is not encrypted it can be compromised.
Check Text: Review system documentation and interview DBA to determine whether data is ever written from database to portable media. If data is written to portable media the data must be protected and access restricted via cryptographic mechanisms. If cryptographic mechanisms are not used to protect data written to portable media, this is a finding.
Fix Text: Configure DBMS to utilize cryptographic mechanisms to restrict access and protect information written to portable digital media.[divider]
