Well, once you understand the concept of a firewall, you can already get an idea of ​​why this protection tool is so important, right? The fact that it inspects the input and output of information from your company already makes it an indispensable solution. After all, unprotected networks are vulnerable to any traffic that tries to access your systems.

Connecting personal computers to other IT systems or the Internet provides a number of benefits, including easier collaboration with others, pooling of resources, and increased creativity. However, this can come at cyprus phone number list cost of complete network and device protection. Hacking, identity theft, malware, and online fraud are common threats that users can face when they expose themselves by connecting their computers to a network or the Internet.

Once discovered by a malicious actor, your network and devices can be easily found, quickly accessed, and exposed to repeated threats. 24/7 internet connections increase the risk of this — since your network can be accessed at any time. Proactive protection is essential when using any type of network. So by using a firewall, users can protect their network from the worst threats.

How a protective firewall works
It acts as a border control between countries, but in the case of companies, it manages the movement of permitted and prohibited information between the internet and private networks. In simpler terms, we can say that the protective firewall is intended to manage web traffic, usually with the aim of slowing down the spread of threats.

It is as if this protection creates bottlenecks to channel data traffic, thus being able to review the information through a set of programmed parameters defined as standard. Some firewalls also track traffic and connections in audit logs to reference what was allowed or blocked.

To gain agility, the firewall can be configured to automatically allow communication of certain types of data, such as HTTP requests (Hypertext Transfer Protocol, the protocol used to access web pages), and to block others, such as connections to email services.

However, policies are initially based on two very simple principles: all traffic is blocked except that which is explicitly authorized; and all traffic is allowed except that which is explicitly blocked. And the default barriers are usually set in two places: dedicated computers on the network or on user terminals, and on hosts.
