Advanced Stake Pool Security (SSH Root Login, 2-Factor Authentication, Fail2Ban)

Staking & Delegation Stake Pool Security

After covering basic server security in a previous video, I wanted to expand more on that matter and show you how to make your servers even sturdier. In this video, I cover disabling SSH root login, setting up 2-Factor Authentication, and installing Fail2Ban, a software package that automatically bans attackers IP addresses.
