Discussion

Application management includes the ability to control the number of users and user sessions that use an application. Limiting the number of allowed users and sessions per user is helpful in limiting risks related to denial-of-service (DoS) attacks. This requirement may be met via the application or by using 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 into 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 must be defined based upon mission needs and the operational environment for each system.

Review the application documentation and deployed configuration to determine whether the application's authentication mechanism limits the number of concurrent sessions to a maximum number of three for all accounts and/or account types.

If the application's authentication mechanism does not limit the number of concurrent sessions to a maximum number of three for all accounts and/or account types, this is a finding.
