Back on ssh topic, i think this is third or perhaps the fourth article regarding ssh, one of my favorite tools on a Linux server, and that a lot of times is not used or configured properly. In this small guide i’ll show you some setup to make your ssh server a bit more safer from the most common attacks.
In particular i’ll show the configurations for openssh that is the most common and used ssh server in all Linux distributions but, as small suggestion, if you are using a VPS and you want to save some memory check also dropbear, it’s a valid alternative to openssh and it saves some space in your ram.
