But what is a firewall and how does it work? Here's a basic briefing...

What is a Firewall?

A firewall is a security system that protects your computers and company network from the threats of malicious software and cyber attacks. Acting as a barrier, the firewall serves as a filter between secure and insecure networks.

Types of Firewalls and Their Uses

Here are the types of firewalls and basic information on when to use them:

• Packet Filtering Firewall: It controls data packets and allows or blocks them according to the rules you set. It is generally fast and economical, but if misconfigured, it can lead to security breaches.
• Stateful Inspection Firewall: An advanced version of the Packet Filtering Firewall. It checks the status and content of the packages to provide more detailed security.
• Proxy Firewall: Manages network traffic as a representative (proxy), so no direct connections are established, enhancing security.
• Next-Generation Firewall (NGFW): This type of firewall, with advanced security functions, can manage security policies at the application level.
• Unified Threat Management (UTM) Firewall: It brings together a series of security features and manages them from a central platform, making its use and management simpler.

In this section, the advantages, disadvantages, and areas of use of each type of firewall are detailed.
