======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
