Broadly speaking, a firewall is part of a network or server that is designed to restrict potentially malicious and unauthorized access to the hardware while still allowing outward communication from the network or server.
There are two types of firewalls; physical hardware firewalls which are devices that connect to the destination server and stop traffic from passing to it and, software-based firewalls that run on a server and filter/reject connection attempts. In both cases, the firewall is at its core, a security measure meant to protect your data from unauthorized access. Today, we are going to review how to install CSF Firewall on a Ubuntu server
