Support SSH log parsing on Linux

[puffyCid]

What new feature do you think would be cool to add to artemis?
Support SSH log parsing on Linux systems. SSH is a common way to remotely access Linux systems.

Describe the solution you'd like
Parsing SSH logs would provide visibility into who has remotely logged onto a system.

Additional context
SSH logs should typically be found somewhere in /var/log. It may depend on the distro.
On Fedora logs are located at /var/log/secure*. They are plaintext files.
Other possible locations:

• /var/log/auth.log
• Journal files?
