# 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

parameters:
  openssh:
    server:
      permit_root_login: False
