    A As a simple trick if you have IPv6 on client and server you can limit the ssh to IPv6 only. The most port scanners doesn't use IPv6.

    @blunix finaly its like thay say in the one hacker movie. NO SYSTEM IS SECURE. We can only try to make it as secure as its possible. On cubes os it possible to read your ram out if the hardware have failures or the kernel of the host.

    I think this is the best solution too. Additional its a good idea to change the listen port of ssh.
