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 server 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 Fix: Edit the /etc/ssh/sshd_config file to set the parameter as follows: PermitRootLogin no


Parameter:

[no/yes]


Technical Mechanism:

Edit the /etc/ssh/sshd_config file to set the parameter as follows: PermitRootLogin no
