Fix Recommendation

Configure OL 9 to limit the number of concurrent sessions to "10" for all accounts and/or account types.

Add the following line to the /etc/security/limits.conf or in a ".conf" file defined in /etc/security/limits.d/:

* hard maxlogins 10

Check Contents

Verify that OL 9 limits the number of concurrent sessions to "10" for all accounts and/or account types with the following command:

$ grep -r -s maxlogins /etc/security/limits.conf /etc/security/limits.d/*.conf
/etc/security/limits.conf:* hard maxlogins 10

This can be set as a global domain (with the * wildcard) but may be set differently for multiple domains.

If the "maxlogins" item is missing, commented out, or the value is set greater than "10" and is not documented with the information system security officer (ISSO) as an operational requirement for all domains that have the "maxlogins" item assigned, this is a finding.
