Check Point IPSO is the operating system for the 'Check Point firewall' appliance and other security devices, based on FreeBSD, with numerous hardening features applied.〔https://honor.icsalabs.com/pipermail/firewall-wizards/2000-February/007795.html〕 The IP in IPSO refers to Ipsilon Networks, a company specialising in IP switching acquired by Nokia in 1997.〔http://europe.nokia.com/microsites/aboutnokia/company_information/news/news_htmls/ntc_971209a.html〕 In 2009, Check Point acquired the Nokia security appliance business, including IPSO, from Nokia.〔http://www.checkpoint.com/nokia/welcome/index.html〕 == Variations == IPSO, now at version 6.2, is a fork of FreeBSD 6. There were two other systems, called IPSO-SX and IPSO-LX, that were Linux-based: * IPSO SX was Nokia's first release of a Linux-based IPSO, and was deployed in 2002 on the now-defunct Message Protector,〔http://www.nokia.com/A4136001?newsid=880176〕 and briefly thereafter on a short-lived appliance version of the "Nokia Access Mobilizer", acquired from Eizel. It had a partitioning scheme somewhat reminiscent of IPSO SB, a LILO configuration and boot manager also somewhat inspired by IPSO SB, and a software package installer that made RPM packaging look more familiar to a Nokia IPSO administrator. It did not, however, include a full configuration database or Voyager web interface, the two things that normally define IPSO. * IPSO LX is a nearly vanilla Gentoo-based Linux OS,〔http://www.secinfo.com/dsvRq.uu2.a.htm〕 and is used on Nokia appliances sold with Sourcefire 3D. It includes a full Voyager and database implementation—in fact, the Voyager look and feel in IPSO SB 4.0 onwards was based on that implemented for IPSO LX. Check Point offers two lines of security appliances - one based on IPSO 6.x, and one based on an operating system called SecurePlatform. 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 IPSO」の詳細全文を読む スポンサード リンク
