The INVISUS® Desktop Firewall protects your computer against attacks from the Internet and from other computers on your local network. It creates a fortress around your PC, making your PC virtually invisible to hackers and other intruders by shielding your computer's IP address from detection.

This professional-grade firewall also acts as a checkpoint to your computer. Every program or application that attempts to get into or out of your PC is stopped at the firewall and checked for its authorization. If the program is not one that you have approved, it is stopped and you immediately receive a warning alert informing you that an unauthorized program is trying to get in our out of your system. This firewall technology is essential for keeping your PC secure from hackers and other unauthorized hacker programs that can use your system without your knowledge.

Your PC being used to attack others

Your computer's address on the Internet (IP address) can be detected by a hacker anywhere in the world - unless you are secured by a solid firewall. Your unsecured IP address is like a welcome mat for hackers, who can enter and control your unprotected PC through any of its more than 65,000 built-in data "ports" - without your knowledge or consent!

These data ports are "doors" to your PC that open and close as needed, and are used by the various programs or applications you have on your computer to communicate with other systems on the Internet or on a network. Leaving these ports unprotected and visible to hackers is like leaving the front door to your home wide open while you sleep at night.

It takes very little technical sophistication for even an amateur hacker to locate your unprotected computer on the Internet. "Script kiddies" (usually young teenage or even pre-teen kids) can easily download hacker tools and utilities from hacker web sites that will automatically scan the Internet and return thousands of IP addresses of unprotected, active PCs. They use other utilities to "ping" or test the IP addresses of these discovered PCs, looking for open ports that can be used to gain access. Once inside your PC, hackers are free to view your files, install spyware, steal your credit and identity information, and even plant "back door" software that lets them re-enter and control your PC at will - and leave no trace that they were ever there.

One of the most effective measures a computer user can take to protect their system is to have a properly installed and configured firewall. The INVISUS® Desktop Firewall is designed to protect your PC against attacks from both the Internet and other computers within your local network. A firewall also acts as a shield to hide your computer, hiding your system's ports, making your computer invisible to hackers and other Internet threats.

You can set the firewall to one of three types of security settings: minimum, medium and maximum security. Minimum security allows all communications with your computer to occur except for specifically defined restrictions. This is the least amount of security you can have with the firewall. When switched to Medium security the INVISUS® Desktop Firewall restricts all Internet and network activity unless you give the firewall permission or have a filter rule in place. If an unknown program tries to connect with your computer, a Connection Alert will appear, and depending on the user's answer, the communication will be denied, permitted temporarily or permitted always. The Maximum security setting blocks all communication to and from the computer that does not match existing filter rules.

The INVISUS® Desktop Firewall blocks or filters all incoming connections to your computer from the Internet and other computers inside a network. The firewall also blocks and filters all outgoing connections to your computer. Trojan horse applications and many other hacker tools work by infecting a computer via authorized programs such as email, and then connecting out from the victim's computer completely undetected. Bi-directional filtering is critical to stopping these types of hacker attacks and other threats -- such as Denial of Service attacks where your computer is used to attack someone else without your knowledge.

Stateful inspection is the firewall's ability to act as a checkpoint for every program and application that tries to connect in our out of your computer. No unauthorized programs or activities can get in our out of your PC because they will first be checked against the firewall's filter rules. The firewall immediately decides whether or not the attempted action is permitted. Hackers cannot use unauthorized channels or programs for their mischief.

The firewall automatically drops unauthorized connections to your PC, and pops up a connection alert window warning you of the failed attempt to connect to your system. Each connection alert is a built-in intrusion detection system that tells you the IP address and description of the intruder that you can use to stay aware of who or what is attempting to access your computer without your permission.

With the INVISUS® Desktop Firewall, you can track every attempted connection to your computer with several levels of detail. The firewall log tracks specific details including the IP Address of the unauthorized intrusion so you can find out who is trying to access your PC without your permission.

In order for the firewall to be able to identify authorized applications correctly, an encrypted signature (MD5) is issued to each authorized application when a filter rule is created. The approved application then uses this signature while trying to initiate any communication in or out of the computer. As this signature is always unique, it will prevent any Trojan horse application's attempt to disguise itself as a trusted application. In essence, the firewall establishes very specific security policies for your PC.
