What is the Best Firewall and virus software for Networked Company?

Answer 1

Answer

A firewall is a piece of software that helps protect a computer and the network its attached to from outside attacks via the internet. Firewalls are very important because malware such as worms can spread very quickly over a network. This is because one computer is infected and then that malware infects other computers connected to the same network the initial computer is attached to.

The idea of a best firewall is subjective. Every companies have different needs and need a different amount of protection. For example Google and Apple are multibillion dollar corporations and are under attacts every day and therefore need a high degree of protection and a very effective firewall. In fact, companies like Apple and Google have multiple firewalls to provide a number of layers of protection.

There are a number of firewalls but in lamens terms there are two main types. The first is where every computer in a network has their own firewall. Windows Pc's have a firewall already installed (though its effectiveness can be argued). This type of firewall ensures protection by protecting each computer individually. This method can be effective but it is not useful for large networks because a network administrator would have to go to every computer to learn about incidences. This method is not ideal for large networks (50 or more computers).

The other type of firewall consolidates protection to one firewall. This is accomplished by running internet acces of everyc computer to a single server (proxy server) and then installing a firewall to run on that server. So, therefore all traffic via the internet for every computer on that network must go throught the server and the firewall that's running. This method is very ideal for large networks because network administrators only have to acces the server to see incidences such as threats to the network.

If you want protection for each computer and have a smaller network I would reccomend installing a anti-malware program like Avast Internet Security on every device attached to the network. If you want a single firewall regulating all network traffic then you will have to configure a proxy server to run a firewall. Any questions feel free to message me
