VPN-1 is a firewall and VPN product developed by Check Point Software Technologies Ltd. VPN-1 is a stateful firewall which also filters traffic by inspecting the application layer. It was the first commercially available software firewall to use stateful inspection. Later (1997), Check Point registered U.S. Patent # 5,606,668 on their security technology that, among other features, included stateful inspection. VPN-1 functionality is currently bundled within all the Check Point's perimeter security products. The product, previously known as FireWall-1, is now sold as an integrated firewall and VPN solution. VPN-1 is one of the few firewall products that is still owned by its creators (Check Point Software Technologies). By contrast, most other commercial firewalls such as Cisco PIX and Juniper NetScreen were acquired by their present owners. == Platforms == The VPN-1 software is installed on a separate operating system, which provides the protocol stack, file system, process scheduling and other features needed by the product. This is different from most other commercial firewall products like Cisco PIX and Juniper firewalls where the firewall software is part of a proprietary operating system. Although traditionally sold as software only, VPN-1 is also sold in appliance form as Check Point's UTM-1 (starting 2006) and Power-1 appliances. These appliances run the SecurePlatform operating system. As of version R70, VPN-1 supports the following operating systems: * Windows Server 2003 and 2008; * Red Hat Enterprise Linux (RHEL); * Check Point SecurePlatform (a Check Point Linux distribution based on Red Hat Enterprise Linux, often called ''SPLAT''); * Nokia IPSO; * Check Point Gaia (a Check Point Linux distribution, unifying IPSO and SecurePlatform into a single operating system); * Crossbeam XOS and COS Previous versions of Check Point firewall supported other operating systems including Solaris, HP-UX and AIX. See the table in the ''Version History'' section below for details. VPN-1 running on the Nokia platform on IPSO is often called a ''Nokia Firewall'' as if it were a different product, but in fact it runs the same VPN-1 software as other platforms. Upon completing the acquisition of Nokia Security Appliance Business in 2009, Checkpoint started the project named Gaia aimed at merging two different operating systems—SecurePlatform and IPSO—into one. This new OS is positioned to finally replace both existing operating systems at some point in the future.〔(Gaia project )〕 On April 17, 2012 Check Point announced the general availability of the Gaia operating system as part of the R75.40 release. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Check Point VPN-1」の詳細全文を読む スポンサード リンク
