A computer firewall is designed to protect your computer from the outside world, there are two different types of a computer security firewall, a hardware and a software firewall. A hardware firewall is an actual device which connects between the Internet and network connection. This provides a physical firewall between the two networks. Software firewalls are installed on computers, and it protects just one computer. Most firms use both hardware and software firewalls to make sure that their computers are protected.
Firewall and internet security goes together like bread and butter. You can not have any kind of internet security without a firewall. If you have more than three computers sharing the one Internet connection then you should consider using some form of hardware firewall system as this provides protection to your whole network without requiring additional protection for each computer. A hardware computer can also act as a security firewall vpn and provides a complete network security firewall which protects the entire network from spyware, hackers, worms, and the other nasties. A hardware firewall will be more expensive than software firewall, however it does protect the whole network which means that it will be cheaper for a larger network.
Software firewalls on the other hand are very useful for protecting individual computers. These are normally called personal firewalls because they are for one computer rather than the whole network. You should use a software firewall on your laptop that you are going to use on wireless public networks such as those at airports and hotels. Make sure that you install the firewall on the laptop that will protect your computer for all different networks.
There is also a new type of hardware firewall which is designed to protect just one computer. This is a simple PCI card which is just inserted inside the computer. It can also be purchased as a PC card which can be installed into a laptops PCMCIA slot. Firewall cards are tamper proof and very easy to set up, this makes them ideal for businesses.
No matter which type of firewall you choose to install, whether it's a hardware or software firewall you just need to make sure that it's installed and set up correctly. This will ensure that all malware and intruders are kept out, and your personal information is not at risk. If you don't use a firewall then you're asking for trouble, even if you don't think that there's anything valuable on your computer it's crazy!
Lots of people are starting to use both software and hardware firewalls to protect their computers as they both provide different protection. This is a very sensible idea for people that spend a lot of their time on the Internet, each firewall is slightly different and offers different protection. By using hardware and software firewalls you can protect your computer from hackers, spyware, identity theft and viruses.
You need a firewall as it forms the first line of defence for your computer, however that does not mean that it should be the only form of protection on your computer, you also need to invest in antivirus software, and antispyware products.
