Vulnerability discussion

When application accounts are disabled, user accessibility is affected. Accounts are used for identifying individual application users or for identifying the application processes themselves.In order to detect and respond to events that affect user accessibility and application processing, applications must audit account disabling actions and, as required, notify the appropriate individuals so they can investigate the event. Such a capability greatly reduces the risk that application accessibility will be negatively affected for extended periods of time and also provides logging that can be used for forensic purposes.To address access requirements, many application developers choose to integrate their applications with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements. Such integration allows the application developer to off-load those access control functions and focus on core application features and functionality.

Check content

Using a web browser on a system that has connectivity to Tanium, access the Tanium web user interface (UI) and log on with CAC. Click on the navigation button (hamburger menu) on the top left of the console. Click on "Connect". Review the configured Sources. If no "Sources" exists to send audit logs from the Tanium SQL Server to a SIEM tool, this is a finding. Work with the SIEM administrator to determine if an alert is configured when accounts are disabled. If there is no alert configured, this is a finding.

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.
