In <code>\/etc\/ssh\/sshd_config<\/code>, change <code>Port 22<\/code> to your custom port (e.g., <code>Port 2224<\/code>):<\/p>\n<pre><code>Port 2224<\/code><\/pre>\n<p>2.

If an IP address fails authentication multiple times within a short window, Fail2ban dynamically updates firewall tables to drop all packets from that IP.<\/p>\n<p>1. Install Fail2ban:<\/p>\n<pre><code>sudo apt install -y fail2ban<\/code><\/pre>\n<p>2.
