Fix Recommendation

Configure the SSH service to automatically start after reboot with the following command:

# systemctl enable sshd.service

Check Contents

Verify SSH is loaded and active with the following command:

# systemctl status sshd
sshd.service - OpenSSH server daemon
Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled)
Active: active (running) since Tue 2015-11-17 15:17:22 EST; 4 weeks 0 days ago
Main PID: 1348 (sshd)
CGroup: /system.slice/sshd.service
1053 /usr/sbin/sshd -D

If "sshd" does not show a status of "active" and "running", this is a finding.
