The Photon operating system must enable Secure Shell (SSH) authentication logging.

Automated monitoring of remote access sessions allows organizations to detect cyberattacks and ensure ongoing compliance with remote access policies by auditing connection activities.

The INFO LogLevel is required, at least, to ensure the capturing of failed login events.

At the command line, run the following command to verify the running configuration of sshd:

# sshd -T|&grep -i LogLevel

Example result:

loglevel INFO

If "LogLevel" is not set to "INFO", this is a finding.

Navigate to and open:

/etc/ssh/sshd_config

Ensure the "LogLevel" line is uncommented and set to the following:

LogLevel INFO

At the command line, run the following command:

# systemctl restart sshd.service
