SV-82289r1_rule Audit tools used in conjunction with SQL Server must be protected from unauthorized access.

Vulnerability discussion

Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Depending upon the log format and application, system and application log tools may provide the only means to manipulate and manage application and system log data. It is, therefore, imperative that access to audit tools be controlled and protected from unauthorized access. Applications providing tools to interface with audit data will leverage user permissions and roles identifying the user accessing the tools and the corresponding rights the user enjoys in order make access decisions regarding the access to audit tools.Audit tools include, but are not limited to, OS-provided audit tools, vendor-provided audit tools, and open source audit tools needed to successfully view and manipulate audit information system activity and records. If an attacker were to gain access to audit tools, he could analyze audit logs for system weaknesses or weaknesses in the auditing itself. An attacker could also manipulate logs to hide evidence of malicious activity.This focuses on external tools for log maintenance and review. Other STIG requirements govern SQL Server privileges to maintain trace or audit definitions.

Check content

In Windows, review the access permissions to tools used to view or modify audit log data (to include traces used for audit purposes). If appropriate permissions and access controls to prevent unauthorized read actions and executions are not applied to these tools, this is a finding.

Fix text

Apply or modify Windows permissions on tools used to view or modify audit log data (to include traces used for audit purposes), to make them accessible by authorized personnel only.

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.
