Great Article on Securing SSH

Not like SSH wasn’t pretty secure before, due to encryption, but every step towards security helps.

I took note to his advice on moving SSH to a non-standard port:

Security though obscurity you scoff? Perhaps. But it’s easy, causes no inconvenience, and might just reduce the number of attacks. That sounds like a winner to me.

I have also noticed that moving SSH to a non-standard port decreasing the amount of hacking activity against SSH by almost 100%.

Also it adds another benefit: the ability to expose SSH on multiple machines that may be natted on a network and sharing a single external IP such as on a cable or dsl modem. Just give each machine you want to expose a different non-standard port to run SSH on. I would recommend a VPN over exposing SSH to the Internet, but in some cases it may be necessary as some remote locations may not allow VPN traffic leaving their networks…
