Vulnerability discussion

If log data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve. In addition, access to log records provides information an attacker could potentially use to his or her advantage. Application servers contain admin interfaces that allow reading and manipulation of log records. Therefore, these interfaces should not allow unfettered access to those records. Application servers also write log data to log files that are stored on the OS, so appropriate file permissions must also be used to restrict access. Log information includes all information (e.g., log records, log settings, transaction logs and log reports) needed to successfully log information system activity. Application servers must protect log information from unauthorized modification.

Check content

At the command prompt, execute the following command: ls -lL /opt/vmware/var/log/vami /opt/vmware/var/log/sfcb If any log files are world-writable, this is a finding.

Fix text

At the command prompt, enter the following command: chmod 640 Note: Replace with the file(s) with world-write rights.

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.
