What is Internet Security & Acceleration Server 2000?

Multi-layer firewall

Maximize security with packet-level, circuit-level, and application-level traffic screening.

High-performance Web cache

Provide users with accelerated Web access and save network bandwidth.

Windows 2000 integration

Manage ISA Server users, configuration, and rules with Windows 2000 Active Directory™ service. Authentication, management tools, and bandwidth control extend Windows 2000 technologies.

Stateful inspection

Examine data crossing the firewall in the context of its protocol and the state of the connection.

Scalability

Add servers to scale up your cache easily and efficiently with dynamic load balancing and the Cache Array Routing Protocol (CARP). Maximize network availability and efficient bandwidth use with distributed and hierarchical caching.

Virtual private networking

Provide standards-based secure remote access with the integrated Virtual Private Networking services of Windows 2000.

Detailed rules for managing traffic and enforcing policy

Control network and Internet access by user, group, application, content type, schedule, and destination.

Broad application support

Integrate with major Internet applications using dozens of predefined protocols.

Transparency for all clients

Compatibility with clients and application servers on all platforms, with no client software required.

Smart application filters

Control application-specific traffic, such as e-mail and streaming media, with data-aware filters that block only certain types of content.

Smart caching

Ensure the freshest content for each user through proactive caching of popular objects, and pre-load the cache with entire Web sites on a defined schedule.

Rich administration tools

Take advantage of powerful remote management capability, detailed logging, customizable alerts, and graphical task pads to simplify security and cache management.

Dynamic packet filtering

Reduce the risk of external attacks by opening ports only when needed.

Distributed and hierarchical caching

Maximize availability and save bandwidth for efficient network utilization, with multiple and backup routes.

Integrated bandwidth control

Prioritize bandwidth allocation by group, application, site, or content type.

Secure publishing

Protect Web servers and e-commerce applications from external attacks.

Efficient content distribution

Distribute and cache Web sites and e-commerce applications, bringing Web content closer to users, improving response times and cutting bandwidth costs.

Integrated intrusion detection

Identify common denial-of-service attacks such as port scanning, "WinNuke," and "Ping of Death."

Built-in reporting

Run scheduled standard reports on Web usage, application usage, network traffic patterns, and security.

System hardening

Secure the operating system with multiple levels of lockdown.

Streaming media support

Save bandwidth by splitting live media streams on the firewall.
