(in version v1 r2)
Title
The system must limit users to 10 simultaneous system logins, or a site-defined number, in accordance with operational requirements. (Cat III impact)
Discussion
Limiting simultaneous user logins can insulate the system from Denial-of-Service problems caused by excessive logins. Automated login processes operating improperly or maliciously may result in an exceptional number of simultaneous login sessions. If the defined value of 10 logins does not meet operational requirements, the site may define the permitted number of simultaneous login sessions based on operational requirements. This limit is for the number of simultaneous login sessions for EACH user account. This is NOT a limit on the total number of simultaneous login sessions on the system.
Check Content
Determine if the system is configured to limit the number of simultaneous logins for user accounts. If it is not, this is a finding.
Fix Text
Configure the system to limit the number of simultaneous logins for user accounts.
