What is a firewall?
This is not something that protects your house against fire. It’s a different thing. In the online world, a firewall is a system specially made for your PC or laptop so to prevent unauthorized access to your network. A firewall can be software or hardware or both. It gives you security in a way that no other internet users, except those you authorized, can filter into your private networks. Firewalls assess the messages that enter and leaves your intranet. If the messages don’t pass the security criteria, your firewall will block those.
What are the different types of firewalls?
There are different types of firewalls that exist. The first firewall is the one that does packet filtering. This kind assesses every packet that enters or leaves your network. It has the power to receive or reject those packets depending on some user rules. This type is pretty effective but users will find it hard to configure. However, your computer may still not protect you from IP spoofing.
The next type is the one that implements a circuit-level gateway. This is a process wherein a firewall does security mechanisms when a UDP or TCP connection is strongly built. With this connection, packets don’t have to undergo more checking to be able to move through hosts.
The third type of firewall serves as a proxy server. This is a kind that gives you the opportunity to hide your real network address. A proxy server can be connected to the internet and still ask for connections to servers and receive the data in place of the real computer. What’s good about this type is that it can only configure selected types of traffic like HTTP files. But, it has a drawback. It can slow down the performance of your network.
Lastly, you can look for a web application firewall that serves as a combination of hardware and software filters. There are a set of rules being used and these can be personalized in order to detect numerous malware and computer attacks.
