I‘d also recommend you look in to Lynis as well as a VPN. To be honest, you should NEVER have SSH open (on any port) to the Internet. It’s far better to whitelist your home IP and use a VPN for mobile travel. This also allows you to keep other services/ports restricted to your use only and prevent bruteforce attacks or worse, 0day/1day attacks.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
