Vulnerability discussion

Audit information includes all information (e.g., audit records, audit settings, and audit reports) needed to successfully audit information system activity.If audit 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 audit records provides information an attacker could use to his or her advantage.To ensure the veracity of audit data, the information system and/or the network device must protect audit information from any and all unauthorized read access.This requirement can be achieved through multiple methods which will depend upon system architecture and design. Commonly employed methods for protecting audit information include least privilege permissions as well as restricting the location and number of log file repositories.Additionally, network devices with user interfaces to audit records should not allow for the unfettered manipulation of or access to those records via the device interface. If the device provides access to the audit data, the device becomes accountable for ensuring audit information is protected from unauthorized access.

Check content

Verify that RiOS is configured to protect audit information from any type of unauthorized read access. Navigate to the device Management Console Navigate to Configure >> Security >> User Permissions Select the view icon next to each user name Verify that the Control "Basic Diagnostics" is set according to the authorization level of the user If the control "Basic Diagnostics" is not set according to the authorization level of the user, this is a finding.

Fix text

Configure RiOS to protect audit information from any type of unauthorized read access. Navigate to the device Management Console Navigate to Configure >> Security >> User Permissions Select the user name that needs to have modified permissions Set the control "Basic Diagnostics" according to the authorization level of the user. Click "Apply" Navigate to the top of the web page and click "Save" to write changes to memory

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.
