Citrix XenDesktop 7.x Delivery Controller STIG:
CXEN-DC-000005
(in versions v1 r3 through v1 r1)
Title
Delivery Controller must limit the number of concurrent sessions to an organization-defined number for all accounts and/or account types. (Cat II impact)
Discussion
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 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 should be defined based on mission needs and the operational environment for each system.
