What isfirewall methods

A Firewall is a cybersecurity tool designed to filter traffic on a network, separating network nodes from external and internal traffic sources, or even specific applications. There are primarily three types of firewalls including software firewalls, hardware firewalls, and a combination of both.

A physical device that connects the computer network and the gateway is a Hardware Firewall, also known as Firewall Appliance. On the other hand, a Software Firewall is a simple program installed on a computer that works through port numbers and other installed software.

Moreover, various types of firewalls provide different features and levels of security. Packet-filtering Firewalls, Circuit-level Gateways, Application-level Gateways, Stateful Multi-layer Inspection (SMLI) Firewalls, Next-generation Firewalls (NGFW), Threat-focused NGFW, Network Address Translation (NAT) Firewalls, Cloud Firewalls, and Unified Threat Management (UTM) are the possible Firewall techniques that can be implemented as software or hardware for added protection.

In conclusion, the best approach is to have both hardware and software firewalls for maximum security. By utilizing firewalls, you can protect your network from unauthorized access while ensuring your sensitive data and information are secured.
