The Server

The server runs:


Currently, the logging and especially log monitoring capabilities on the server are lackluster. Logging settings have not been changed for most processes. Some log to syslog/systemd-journal while others write logs in /var/log/.

Network Traffic Accounting

Network traffic accounting is handled relatively well. The server uses vnStat 2.6 to aggregate network traffic for each interface.

A very simple web frontend (that I wrote) is available for vnStat.

Remote Access (SSH)

Remote access into the server is done using SSH. The server runs OpenSSH 8.4.

Password authentication is disabled. Public-key authentication is required to log in. Logging in as root is disabled, as well as for several mail-only accounts.

One possible security enhancement would be to enforce two-factor authentication when logging in via SSH. However, this is risky because losing the second factor means locking yourself out of the server.

Vultr Web Console

It's also possible to log in using a username/password from the Vultr website, which provides a web interface to the TTY.
