SSH Hardening

In this section, we will take a look at SSH Hardening.

  • SSH is used for logging into a remote machine and for executing commands on a remote machine.

  • The basic syntax of doing this is to run the SSH command followed by the IP address or hostname of the server you want to connect to.

  • A more secure way is to make use of a cryptographic key pair that uses private and public keys to authenticate to the system.

  • To improve the security of the system:

    • Disable SSH for the root account. This ensures that no one can login remotely using the root account and only as their own user account
