======5.2.8 Ensure SSH root login is disabled (Scored)======
=====Profile Applicability=====
Level 1 - Server
Level 1 - Workstation
=====Description=====
The ''PermitRootLogin'' parameter specifies if the root user can log in using ssh(1). The default is no.
=====Rationale=====
Disallowing root logins over SSH requires system admins to authenticate using their own individual account, then escalating to root via ''sudo'' or ''su''. This in turn limits opportunity for non-repudiation and provides a clear audit trail in the event of a security incident
=====Audit=====
Run the following command and verify that output matches:
# grep "^PermitRootLogin" /etc/ssh/sshd_config
PermitRootLogin no
=====Remediation=====
Edit the ''/etc/ssh/sshd_config'' file to set the parameter as follows:
PermitRootLogin no
