SLEM 5 must limit the number of concurrent sessions to 10 for all accounts and/or account types.

Description
SLEM 5 management includes the ability to control the number of users and user sessions that use a SLEM 5. 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.

Who does this work

8 NICE work roles and 6 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-261367r996839_chk)

Verify SLEM 5 limits the number of concurrent sessions to 10 for all accounts and/or account types with the following command: > grep "maxlogins" /etc/security/limits.conf * hard maxlogins 10 If the "maxlogins" does not have a value of "10" or less, is commented out, or is missing, this is a finding.

Fix Text (F-65004r995967_fix)

Configure SLEM 5 to limit the number of concurrent sessions to "10" or less for all accounts and/or account types. Add or modify the following line to the file "/etc/security/limits.conf": * hard maxlogins 10
