SV-87301r1_rule Access to database files must be limited to relevant processes and to authorized, administrative users.

Vulnerability discussion

Applications, including DBMSs, must prevent unauthorized and unintended information transfer via shared system resources. Permitting only DBMS processes and authorized, administrative users to have access to the files where the database resides helps ensure that those files are not shared inappropriately and are not open to backdoor access and manipulation.

Check content

Review the permissions granted to users by the operating system/file system on the database files, database log files, and database backup files. At the command prompt, execute the following command: # find /storage/db/vcops/cassandra/data -type f ! \( -user admin -o -user root \) If any files are listed that are not owned by either "admin" or "root", this is a finding.

Fix text

Configure the permissions granted by the operating system/file system on the database files, database log files, and database backup files so that only relevant system accounts and authorized system administrators and database administrators with a need to know are permitted to read/view these files. At the command line execute the following command: # chown root Replace with the files that are not owned by either "admin" or "root".

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.
