This is usually over the Internet, but may also be over other unprotected networks. This allows secure streams of data to terminate to your firewall. Almost all firewalls today provide VPN services. Many firewall products today can integrate several different technologies. The following technologies are usually the minimum that companies should implement to provide security in the organization.Ī firewall can contain many different types of technology to increase its importance in your network. These additional devices help ensure a network that has security covered from all angles. A firewall is the core of securing your network, but there are other products out there that should also be implemented in your network. This book covers the Juniper NetScreen firewall product line and focuses on that specific product and technology. Ralph Bonnell, in Configuring Juniper Networks NetScreen & SSG Firewalls, 2007 The Battle for the Secure Enterprise ISA Server 2004 also supports Web proxy chaining, which allows the ISA Server 2004 firewall to forward Web requests to an upstream Web proxy server.īrad Woodberg. ISA Server 2004 gives you an optimized disk cache store that minimizes disk access for both read and write operations.
This optimizes response time by retrieving items from memory, rather than from disk. Web objects requested by remote users are cached on the ISA Server 2004 firewall, and subsequent requests for the same objects are served from the firewall's Web cache instead of forwarding the request to the published Web server located behind the ISA Server 2004 firewall.įast RAM caching allows the ISA Server 2004 firewall to keep most frequently accessed items in memory. Reverse caching allows the ISA Server 2004 firewall to cache objects retrieved by remote users from servers that have been published by the ISA Server 2004 firewall. Forward caching allows the ISA Server 2004 firewall to cache objects retrieved by internal users from external Web servers. How does ISA Server 2004 compare? ISA Server 2004 includes Web-caching functionality at no extra charge. Web caching/acceleration can be added to a network using NetScreen products by implementing a caching solution such as ISA Server on the network. NetScreen firewall/VPN appliances do not provide Web-caching functionality. Tom Shinder's Configuring ISA Server 2004, 2005 NetScreen: Web Caching Shinder, Debra Littlejohn Shinder, in Dr.
