SUSE operating system management includes the ability to control the number of users and user sessions that utilize a SUSE operating system. Limiting the number of allowed users and sessions per user is helpful in reducing the risks related to Denial-of-Service (DoS) attacks.

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.


Configure the SUSE operating system to limit the number of concurrent sessions to 10 or less for all accounts and/or account types.

Add the following line to '/etc/security/limits.conf' or /etc/security/limits.d/*.conf file:

* hard maxlogins 10
