Description
Application management includes the ability to control the number of users and user sessions that utilize an application. Limiting the number of allowed users and sessions per user is helpful in limiting risks related to DoS attacks. This requirement may be met via the application or by utilizing information system session control provided by a web server with specialized session management capabilities. If it has been specified that this requirement will be handled by the application, the capability to limit the maximum number of concurrent single user sessions must be designed and built in to the application. This requirement addresses concurrent sessions for information system accounts and does not address concurrent sessions by single users via multiple system accounts. The maximum number of concurrent sessions should be defined based upon mission needs and the operational environment for each system.

Who does this work

8 NICE work roles and 6 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-254875r1067678_chk)

1. Using a web browser on a system that has connectivity to the Tanium Application, access the Tanium Application web user interface (UI) and logon with multifactor authentication. 2. Click "Administration" on the top navigation banner. 3. Under "Configuration", select "Settings". 4. Click the "Advanced Settings" tab. 5. In the "Filter items" search box, type "max_soap_sessions_per_user". 6. Click "Enter". If no results are returned, this is a finding. If results are returned for "max_soap_sessions_per_user", but the value is not "1024", this is a finding.
