What is Firewall in Cyber Security?

What is firewall in cyber security? Ideally, a firewall is one of the network security devices that monitors and screens the network traffic that enters and leaves. Moreover, it functions as a defence wall separating the accessible web and private networks.

These security systems inspect the traffic with security rules to determine and block unauthorized entry and threats.

Role of Firewalls in Cyber Security

Firewalls monitor efforts made by unauthorized traffic to access the operating system. These security systems create a barrier between the networks and your device. These are great controllers of traffic, verifying and handling the network access of your clients. Generally, security software and OS come with pre-installed firewalls.

A built-in IPS (intrusion prevention system) with a firewall can obstruct application layer or malware attacks. While these are invaluable to minimize threats, buy cyber insurance to cover your financial losses due to a cyberattack.

◦ Perfect for blocking specific websites.

◦ Home users can find this type quite useful.

◦ Very easy to maintain.

◦ Supervising parental controls and juniors is possible.

2. Hardware Firewall

The physical equipment, a dedicated piece of a computer, executes firewall responsibilities. It includes a router placed between the internet gateway and a computer. Its advantages comprise:

◦ Faster response time

◦ Operates independently to avoid most cyberattacks.

◦ External installation frees resources from the server

◦ Manages extra data packets with improved bandwidth

Firewall Best Practices
