- Manually installing the ISA firewall client.
- Date - Nov 28, 2001
- Section - Tutorials / Configuration - General
- The main reason that the firewall client is beneficial to an organization is that user or group access control can be used. Secure NAT does not allow this. The firewall logging is also more detailed, and you are also able to see which users are visiting which internet resources. The downfalls of the firewall client are that the software has to be installed on each machine that needs to become a firewall client and that the software is only Microsoft 9X and above compliant. Firewall clients only support TCP & UDP protocols.

During the contract period, hundreds of your company's employees will access a special Web site created by your partner company. The Web site contains a lot of documentation and other information that your employees will use during the contract period. To make the best use of Web site and to speed that Web site's information along to your employees, you make sure your cache policy is working in the most effective way, and as users begin accessing the Web site, your ISA Server arrays begin caching the data from the special Web site in order to serve it to your users more quickly.
- Configuring RAM Caching.
- Date - Oct 02, 2001
- Section - Tutorials / Configuration - General
- One of the main features of ISA Server is its ability to cache Web pages so that clients can be served from the cache instead of Internet. In order words, when a client requests a Web page, ISA Server, according to the configured rules, retrieves that page from the Web, caches it, and returns the page to the client. When another client requests the same page, it can now be directly returned to the client from the cache, according to the TTL value. This caching function accounts for ISA's "acceleration feature. After all, ISA Server can more quickly serve a client from its disk cache than from the Internet.

- DNS for ISA Server.
- Date - Sep 11, 2001
- Section - Tutorials / Installation & Planning
- Want some more fun? Let’s look at the ISA scenario. What many folks will do is place DNS resolver IPs in both NICs, ISP in the external, local in the internal. While this seems to make sense, it’s actually very inefficient and you can actually cause huge timeouts this way. Remember that TCP/IP will choose the route for a given packet based on its destination, not where it found the data. This means that DNS entries are not really NIC-specific, it’s just more meaningful to the person entering them.

This may include corporate clients or even Internet clients accessing your Web site.
- Configuring Firewall Chains
- Date - Aug 07, 2001
- Section - Tutorials / Configuration - Security
- ISA Server supports both distributed and hierarchical caching. In distributed caching, the ISA Server cache is distributed among array members. In hierarchical caching, different ISA Servers or arrays can connect to other ISA Servers or arrays for cached data access, or eventual access to the Internet. The array closest to the Internet is considered the "upstream" array while the array that is most far from the Internet is considered the "downstream" array. Aside from caching, a chained configuration can provide authentication functions as well.

- I watch the ISA Server web boards very closely. I’ve observed over the last few months that a lot of people would benefit from a description on how to set up a “simple” network using the ISA Server as a Web Proxy Cache and Firewall. A simple network is one that has a single internal network ID. This is a non-routed network. A complex network would be an internal network with multiple network IDs and therefore is a routed network. I’ll write about how to configure ISA Server to work in routed environments in the future.

When enabled, ISA will identify when an attack is attempted against your network and performs a set of manually configured alerts in case of an attack. To detect unwanted intruders, ISA Server compares network traffic and log entries to well-known attack methods. Suspicious activities trigger alerts. Actions include connection termination, service termination, e-mail alerts, logging, and others.

- Publishing a web site located on the ISA Server entails some special problems you must address before you begin publishing. By default, IIS wants to use Port 80 to listen for inbound web requests. However, since the ISA Server’s Web Proxy service uses Port 80 to Listen for inbound web requests, you cannot have both the ISA Server and the IIS WWW Service both listening on the same port.

- Microsoft ISA Server Adds To A Firewall But Can't Replace It.
- Date - Feb 07, 2001
- Section - Articles
- One more component for the kitchen sink or real security value? That depends on what you're looking for. Microsoft Corp.'s Internet Security and Acceleration (ISA) Server is a mixed bag. It does offer some useful and innovative features, such as access control based on user and group affiliation, integrated caching of Web content, and transparent inbound Web proxying, similar to Novell's BorderManager. But for more complex scenarios, ISA Server doesn't quite meet expectations. My test network at our Real-World Labs® at Syracuse University was straightforward (see "ISA Server Test Network," below), and I was disappointed to see that I couldn't achieve the kind of access control, including restricting internal users from internal servers, with ISA Server that's possible with other common firewalls. ISA Server is a good fit in networks with modest access-control needs and simple architectures. For more granular access control to servers and services, you'd be better off with a dedicated firewall package.
