Description
Lack of authentication and identification enables nonorganizational users to gain access to the application or possibly other information systems and provides an opportunity for intruders to compromise resources within the application or information system. Nonorganizational users include all information system users other than organizational users, which includes organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors and guest researchers). Nonorganizational users must be uniquely identified and authenticated for all accesses other than those accesses explicitly identified and documented by the organization when related to the use of anonymous access, such as accessing a web server.

ℹ️ Check
1. Using a web browser on a system that has connectivity to the Tanium application, access the Tanium application web user interface (UI) and log on with multifactor authentication. 2. Click "Administration" on the top navigation banner. 3. Under "Permissions", select "Users". 4. Compare users listed to the prepared documentation. If documentation identifying the Tanium console users and their respective User Groups, Roles, Computer Groups, and associated LDAP security groups does not exist, this is a finding.
