This wizard enables you to tighten your security considerably. We will explore site and content rules in detail. Rules enable you to control the flow of traffic to meet your security needs.

As you may know, businesses that have standardized on Compaq's servers can use Compaq's Web-enabled management software to manage their systems. The wide range of components that can be managed includes RAID configurations and free hard disk space to IP addresses and serial numbers.
You can even restart the server remotely and get into the management tools. Well, you say, that sounds pretty cool. So what's the problem? Well, the problem is that some newbie administrator may not realize that Compaq's management software running any Web-based management tool on port can act as a proxy server. This could potentially leave the server wide open to folks on the Internet, unless the administrator changes the default configuration before connecting the server to the Internet.
With the default username administrator and password administrator known to everyone, hackers can have anonymous access to the server. By the way, Compaq has a security patch available for Windows NT 4.
