When was firewall invented and who invented it?

quote\nCheck Point FireWall-1 is based upon Stateful Inspection, the de facto standard for Internet firewalls invented by Check Point Software Technologies (U.S. Patent No. 5,606,668 and 5,835,716). Stateful Inspection provides the highest level of security possible by incorporating communication- and application-derived state and context information, which is stored and updated dynamically.\n/quote

ARPANET, the "Mother of the Internet,"  began as a U.S. government experiment linking researchers with remote computer centers to allow them to share hardware and software resources.\n\nI hope this helps!\n\n--Stacey

Norton Internet Security, McAfee, Kerio.\n\nBasically the first time you open up the p2p client your firewall will ask you if you want to allow this program access and you click allow access in all ports permanently and then you're set

It was invented by university types in the 1960s with the idea that a system of communication was needed that would survive an atomic attack. It started out as a pair of computers successfully sharing information and it built from there.\n\nSee ARPA

It depends on which firewall, and there are many kinds (both software and hardware). Most people probably have Windows XP's firewall, which can be turned on/off from the Control Panel.

There is a saying that goes "prevention is better than cure". A firewall in layman terms is essentially a program wich filters network data to decide whether or not to forward them to their destination or to deny it. Well, getting to the point there are good free firewalls, such as:\n-sygate\n-zone alarm\n-xp\nsome other are also very good but are not for free, but you can make the download with emule:\n-Black Ice defender\n-Lockdown 2000\nok?

Zone Alarm.\n\nThis is the best Firewall from my experience, nothing gets through.\n\nThe only problem is it blocks EVERYTHING, you have to allow certain processes to have access not only to the internet but also to the privileged zone.

Iptables is the user space tool to configure a firewall on linux. You need to understand and write iptables rules in order to make a firewall. In case you find a problem you can use any of the graphical front ends like Firestarter or something like Shorewall available to configure a firewall on linux. You also have the option of using a firewall distribution like IPCOP or Smoothwall.

A firewall is a protection system for your computer that protects it from unsolicited communication when you are on a network.\nIf you use a good firewall then it will not only suspicious incoming traffic in the form of viruses,trojans,worms,spyware etc but also outgoing traffic.\nWhen you already have some virus in your computer and the virus wants to spread itself using  your internet connection then a firewall will prevent even that.\nThese days its a must to use a firewall as virus activity is growing.also use the Y! toolbar's spyware removal tool.It is very good for removing spayware that are not caught by your firewall.

firewalls limit incoming and outgoing data either personal or group. they are designed to protect from malicious intentions.

No one person invented the Internet as we know it today. However, certain major figures contributed major breakthroughs: \nLeonard Kleinrock was the first to publish a paper about the idea of packet switching, which is essential to the Internet. He did so in 1961. Packet switching is the idea that packets of data can be "routed" from one place to another based on address information carried in the data, much like the address on a letter. Packet switching replaces the older concept of "circuit switching," in which an actual electrical circuit is established all the way from the source to the destination. Circuit switching was the idea behind traditional telephone exchanges.

The USSR's launch of Sputnik spurred the United States to create the Advanced Research Projects Agency (ARPA, later known as the Defense Advanced Research Projects Agency) in February 1958 to regain a technological lead. ARPA created the Information Processing Technology Office (IPTO) to further the research of the Semi Automatic Ground Environment program, which had networked country-wide radar systems together for the first time. J. C. R. Licklider was selected to head the IPTO, and saw universal networking as a potential unifying human revolution. Licklider recruited Lawrence Roberts to head a project to implement a network, and Roberts based the technology on the work of Paul Baran who had written an exhaustive study for the U.S. Air Force that recommended packet switching (as opposed to Circuit switching) to make a network highly robust and survivable. After much work, the first node went live at UCLA on October 29, 1969 on what would be called the ARPANET, the "eve" network of today's Internet.\n\nThe first TCP/IP wide area network was operational by 1 January 1983 , when the United States' National Science Foundation (NSF) constructed a university network backbone that would later become the NSFNet. (This date is held by some to be technically that of the birth of the Internet.) It was then followed by the opening of the network to commercial interests in 1995. Important separate networks that offered gateways into, then later merged into the NSFNet include Usenet, Bitnet and the various commercial and educational X.25 Compuserve and JANET. Telenet (later called Sprintnet), was a large privately-funded national computer network with free dialup access in cities throughout the U.S. that had been in operation since the 1970s. This network eventually merged with the others in the 1990s as the TCP/IP protocol became increasingly popular. The ability of TCP/IP to work over these pre-existing communication networks allowed for a great ease of growth. Use of Internet as a phrase to describe a single global TCP/IP network originated around this time.\n\nThe network gained a public face in the 1990s. In August 1991 CERN, which straddles the border between France and Switzerland publicized the new World Wide Web project, two years after Tim Berners-Lee had begun creating HTML, HTTP and the first few web pages at CERN. In 1993 the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign released the Mosaic web browser version 1.0, and by late 1994 there was growing public interest in the previously academic/technical Internet. By 1996 the word "Internet" was common public currency, but it referred almost entirely to the World Wide Web.\n\nMeanwhile, over the course of the decade, the Internet successfully accommodated the majority of previously existing public computer networks (although some networks such as FidoNet have remained separate). This growth is often attributed to the lack of central administration, which allows organic growth of the network, as well as the non-proprietary open nature of the Internet protocols, which encourages vendor interoperability and prevents any one company from exerting too much control over the network.

Creation of Internet - \nThe USSR's launch of Sputnik spurred the U.S. to create the Defense Advanced Research Projects Agency (DARPA) to regain a U.S. technological lead. DARPA created the Information Processing Technology Office to further the research of the Semi Automatic Ground Environment program, which had networked country-wide radar systems together for the first time.

there are 2 kinds of firewalls\n\n1. hardware firewall - Buy a router that acts as a firewall\n2. software firewall - dowload programs that are software firewalls. basically they hide your computers ports and prevent people from accessing your comm ports. you can get a software firewall at www.zonealarm.com

A firewall sits between your computer and the internet.  it blocks unwanted connections from hackers.

The answer to that question? Yes and no. Let me explain.\n\nYou see, there are two different types of firewalls:\n\nHardware Firewall: Usually in a router.\n\nSoftware Firewall: Software installed on your PC to act as a firewall.\n\nSo, what do I recommend, and also personally use?\n\nDo NOT use more than one software firewall.\n\nI recommend a software firewall. ZoneAlarm (www.zonelabs.com) is a good free one.\n\nA hardware firewall won't hurt, and pretty much anyone will increase your security. Optional but it gives piece of mind and definite security.\n\nHope this helps!
