Microsoft ISA Server 2004 Help: Consulting, Support, Troubleshooting

Features Microsoft ISA Server 2004
Microsoft Internet Security and Acceleration (ISA) Server 2004 is the advanced application-layer firewall, virtual private network (VPN), and Web cache solution that enables customers to easily maximize existing IT investments by improving network security and performance.

ISA Server 2004 provides advanced protection, ease of use, and fast and secure access for all types of networks. It is particularly well suited for protecting networks that are running Microsoft applications, such as Microsoft Outlook Web Access (OWA), Microsoft Internet Information Services, SharePoint Portal Server, Routing and Remote Access Service, Active Directory service, and others.

ISA Server 2004 contains a full-featured, application-layer-aware firewall that helps protect organizations of all sizes from attack by both external and internal threats. ISA Server 2004 performs deep inspection of Internet protocols such as Hypertext Transfer Protocol (HTTP), which enables it to detect many threats that traditional firewalls cannot detect. The integrated firewall and VPN architecture of ISA Server support stateful filtering and inspection of all VPN traffic. The firewall also provides VPN client inspection for Microsoft Windows Server 2003-based quarantine solutions, helping to protect networks from attacks that enter through a VPN connection. In addition, a completely new user interface, wizards, templates, and a host of management tools help administrators avoid common security configuration errors.

Microsoft ISA Server 2004 includes powerful management tools to simplify critical processes including policy definition, traffic routing, server publishing, and monitoring. ISA Server 2004 builds on Windows Server 2003 security, directory, virtual private networking (VPN), and bandwidth control. The firewall and cache can be deployed on their own dedicated servers or integrated on the same physical computer. In either configuration, ISA Server can significantly enhance network security, enforce consistent Internet usage policy, accelerate Internet access, and improve employee productivity.

Benefits of Microsoft ISA Server 2004
Key benefits that set Microsoft ISA Server 2004 apart from ISA Server 2000 and other firewall solutions include its advanced protection capabilities, its ease of use, and its ability to provide fast and secure Internet access.

• Advanced Protection
  ISA Server 2004 is designed to protect your business from the new generation of attacks by providing stateful packet filtering and circuit filtering. Stateful packet filtering determines which packets will be allowed to pass through to the secured network circuit and application-layer proxy services. This filtering dynamically opens ports only as needed and then closes the ports when the communication ends. Circuit filtering provides application-transparent circuit gateways for multiplatform access to Windows Media technologies, Telnet, RealAudio, IRC, and many other Internet protocols and services. The circuit-layer security of ISA Server 2004 works with dynamic packet filtering to enhance security and ease of use.

In addition to stateful packet and circuit filtering, ISA Server 2004 also controls application-specific traffic with application, command, and data-aware filters. Through intelligent filtering of VPN, HTTP, File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), Domain Name System (DNS), H.323 conferencing, streaming media, and remote procedure call (RPC) traffic, ISA Server can accept, reject, redirect, and modify traffic based upon its contents.

• Ease of Use
  ISA Server 2004 is flexible and easy for administrators to use. It includes multinetworking architecture capabilities, unified VPN, and firewall management through a robust visual policy editor, intuitive network templates, automated wizards, and enhanced troubleshooting tools. ISA Server 2004 also simplifies firewall setup by automatically installing both firewall and Web-caching components. In addition, it supports exporting configuration information to Extensible Markup Language (XML), real-time firewall session monitoring, firewall user groups, and more.
• Fast and Secure Access
  ISA Server 2004 provides fast and secure Internet access by fully integrating VPN functionality into the firewall architecture, accelerating Web caching, and maximizing firewall filtering speeds. Built-in IPsec tunnel mode support for site-to-site VPN connections makes it easy to connect ISA Server 2004 to branch office VPN providers. IPsec tunnel mode support also provides deep VPN client inspection and firewall policy support for Windows-based quarantine solutions, helping companies' user communities become more secure. Support for the latest third-party filters and a comprehensive software development kit (SDK) further extend the capabilities of ISA Server.

New Features of ISA Server 2004
ISA Server 2004 includes many new features and improvements, particularly when installed on a system running Windows Server 2003. These include:

• A new, simplified user interface
• Support for multiple networks
• Improved VPN support
• VPN quarantine capabilities
• Ability to create custom firewall user groups
