Vulnerability discussion

Users granted privileges not required to perform their assigned functions are able to make unauthorized modifications to the production data or database. Monthly or more frequent periodic review of privilege assignments assures that organizational and/or functional changes are reflected appropriately.

Check content

Review policy, procedures and implementation evidence to determine if periodic reviews of user privileges by the ISSO are being performed. Evidence may consist of email or other correspondence that acknowledges receipt of periodic reports and notification of review between the DBA and ISSO or other auditors as assigned. If policy and procedures are incomplete or no evidence of implementation exists, this is a finding.

Fix text

Develop, document and implement policy and procedures for periodic review of database user accounts and privilege assignments. Include methods to provide evidence of review in the procedures to verify reviews occur in accordance with the procedures.

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.
