History

[edit]

Microsoft Proxy Server

[edit]

The Microsoft Forefront Threat Management Gateway product line originated withMicrosoft Proxy Server. Developed under thecode-name "Catapult",[5] Microsoft Proxy Server v1.0 was first launched in January 1997,[6] and was designed to run onWindows NT 4.0. Microsoft Proxy Server v1.0 was a basic product designed to provide Internet Access for clients in a LAN Environment viaTCP/IP. Support was also provided forIPX/SPX networks (primarily used in legacyNovell NetWare environments), through aWinSock translation/tunnelling client which allowed TCP/IP applications, such as web browsers, to operate transparently without any TCP/IP on the wire. Although well-integrated into Windows NT4,[7] Microsoft Proxy Server v1.0 only had basic functionality, and came in only one edition. Extended support for Microsoft Proxy Server v1.0 ended on 31 March 2002.[6]

Microsoft Proxy Server v2.0 was launched in December 1997,[8] and included better NT Account Integration, improvedpacket filtering support, and support for a wider range ofnetwork protocols. Microsoft Proxy Server v2.0 exited the extended support phase and reachedend of life on 31 December 2004.[8]

ISA Server 2000

[edit]

On 18 March 2001, Microsoft launchedMicrosoft Internet Security and Acceleration Server 2000 (ISA Server 2000).[9] ISA Server 2000 introduced theStandard andEnterprise editions, with Enterprise-grade functionality such as High-AvailabilityClustering not included in the Standard Edition. ISA Server 2000 requiredWindows 2000 (any edition), and will also run onWindows Server 2003. In accordance with Microsoft's Support Lifecycle Policy, ISA Server 2000 was the first ISA Server product to use the 10-year support lifecycle with 5 years ofMainstream support and five years ofExtended support. ISA Server 2000 reached End of Life on 12 April 2011.[9]

ISA Server 2004

[edit]

Microsoft Internet Security and Acceleration Server 2004 (ISA Server 2004) was released on 8 September 2004.[10] ISA Server 2004 introduced multi-networking support[clarification needed], integrated virtual private networking configuration, extensible user and authentication models,application layer firewall support,Active Directory integration,SecureNAT[clarification needed], and improved reporting and management features. The rules based configuration was also considerably simplified over ISA Server 2000 version.

ISA Server 2004 Enterprise Edition included array support, integratedNetwork Load Balancing (NLB), andCache Array Routing Protocol (CARP). One of the core capabilities of ISA Server 2004, dubbed Secure Server Publishing, was its ability to securely expose their internal servers to Internet. For example, some organizations use ISA Server 2004 to publish theirMicrosoft Exchange Server services such asOutlook Web Access (OWA),Outlook Mobile Access (OMA) orActiveSync. Using theForms-based Authentication (FBA) authentication type, ISA Server can be used to pre-authenticate web clients so that traffic from unauthenticated clients to published servers is not allowed.

ISA Server 2004 is available in two editions, Standard and Enterprise. Enterprise Edition contains features enabling policies to be configured on an array level, rather than on individual ISA Servers, and load-balancing across multiple ISA Servers. Each edition of ISA Server is licensed per processor. (The version included in Windows Small Business Server 2000/2003 Premium includes licensing for 2 processors.)

ISA Server 2004 runs onWindows Server 2003 Standard or Enterprise Edition. Appliance hardware containing Windows Server 2003 Appliance Edition and ISA Server Standard Edition is available from a variety of Microsoft Partners.[11]

  • Support forExchange Server 2007 (referred to as "Exchange 12" in the Microsoft ISA Server 2006 Evaluation Guide)[13]: 73 
  • New configuration wizards for various tasks such as setting up a "site-to-site VPN connection", publishing SharePoint services, publishing websites, creating firewall rules.[13]: 75, 80 
  • Introduction ofsingle sign-on for groups of published web sites.[13]: 82 
  • Improvements to user authentication including the addition ofLDAP Authentication support[13]: 82 
  • Resistance toflood attacks, to protect the ISA server from being "unavailable, compromised, or unmanageable during a flooding attack."[13]: 55, 62–64, 81 
  • Performance features such asBITS Caching, Web Publishing Load Balancing andHTTP compression.[13]: 84 

ISA Server Appliance EditionMicrosoft also offered ISA Server 2006 Appliance Edition. It was designed to be pre-installed onto OEM hardware (server appliances) that are sold by hardware manufacturers as a stand-alone firewall type device.[14] Along with Appliance Edition, ISA server 2006 Standard Edition and Enterprise Edition were available in preconfigured hardware.[13]: 76
