Secure SSH to Your Cloud Servers

Make SSH Access to Your Cloud Impenetrable to Hackers with Dome9



There are many ways to secure SSH. You can use OpenSSH or other tools to create public key authentication; modify the SSH listening port from 22 to something else; disable root login via SSH; and of course – use strong user passwords and passphrase for your keys. At the end of the day, however, all of these leave one very important and gaping hole in your security: the SSH port on your server is always open to the Internet. This means your server is susceptible to hackers and exploits with automated scripts to scan the net for SSH daemons and attempt to gain access to your server.

Dome9 eliminates break in attempts and maximizes SSH security by letting you you keep all ports closed at all times, and then open the necessary ports on-demand only when, for whom, and as long as is needed.
