Frequently Asked Questions
How does SSH work?
SSH creates an encrypted channel between a client and a server, authenticates the user with a password or key, and then allows secure shell access or file transfer.
How do you harden an SSH server?
Disable root login and password authentication, use key-based logins, restrict users, and keep software updated. Changing the port alone is not enough.
How do attackers abuse SSH?
They use stolen keys for lateral movement and tunnels to pivot into networks. This free Codelivly room covers both attacks and defenses for beginners.
