Running A Good Firewall Software Program Will Stop Those Internet Criminals In Their Tracks

The use of good firewall software along with a top notch anti virus program will give you the added security to lock your computer from internet thieves . The internet is full of these nice people who have the ability to break into your pc and steal your personal information and even your identity .

No matter how well you keep up with critical updates for your operating system ,they will always find a security hole that leaves you open for attack , but there are ways to protect yourself.

Unlike most businesses , the home user is more likely not to secure their pc properly , and that makes you an easy target for these hackers. This is where a good firewall software program will stop them in their tracks !

Why you should have a firewall:

Connecting to the Internet is like opening a big door to your computer. After the door is opened , you can easily go online to browse , send e-mails , and more. But that open door also allows hackers and thieves to easily gain access to your PC.

Once inside, they can steal your valuable personal data, such as bank account numbers credit card info and passwords. Your PC can even be used without your knowledge to launch attacks on other computers, even on entire networks. A hacker can render your computer useless—to everyone except the hacker.

To protect yourself from these attacks, you need a good firewall software program . A PC firewall shuts your computer's door to criminals , allowing only authorized traffic to flow through. Antivirus software protects you from known viruses and can help clean up after a virus attack , but only PC firewalls can block unauthorized access to your Internet-connected computer and protect against both known and unknown malicious software and Internet threats. A PC firewall allows your computer complete, unrestricted access to the Internet.

Two types of firewalls :

Hardware Firewall :

A hardware firewall is a hub or router that sits between your pc and the internet connection . The hub or router will mask the IP address of all computers plugged into it and convert their addresses into a single address assigned to the unit. It does this using the technology called NAT, Network AddressTranslation and this makes your pc invisible to the internet and will block unwanted data from accessing your computer . This makes it so that your hardware firewall accepts all incoming requests you asked for and then forwards them on to the requesting internal computer. Using this method, outside machines are never able to connect directly to your computers.

Personal Firewall :

A personal firewall is a firewall software program installed on a pc . It only allows data that has been requested (such as opening a website or document ) and prevents other outside computers from connecting directly to yours. Personal firewalls tend to have more features than hardware versions, but they don't have the ability to allow you to share your Internet connection with other computers on a network.

There are two kinds of personal firewalls:

1 : A basic PC firewall acts as a barrier between your PC and the Internet Its job is to prevent Internet threats from spreading to your computer. While working in the background, a basic PC firewall will monitor the incoming traffic flowing to your computer from the Internet. If anything seems suspicious, such as a request from an unknown source to connect to your PC, a basic PC firewall automatically identifies and blocks it. It also hides your Internet-connected PC from from the internet.

2 : Dynamic firewall, A basic PC firewall keeps your computer open to the Internet at all times while monitoring the traffic flow . A dynamic PC firewall will automatically open your computer to the Internet when needed, allowing only authorized inbound and outbound traffic to flow , then immediately shuts the door. As a result, a dynamic PC firewall offers more protection to an always on broadband - DSL connection .

There are many free firewalls available but they do not offer the features and control of a good commercial program . Firewalls can sometimes affect the operation of some applications or programs, but with a top firewall software program you have the ability to set specific rules to solve those kinds of issues .
