When the use of a proxy server provides privileged access to locations and system, the use of that server may be restricted. Typically, a user begins his or her use of the application gateway by providing some form of credentials to the proxy server. This can be done using several mechanisms, with two of the more popular mechanisms discussed below.
The SOCKS4 protocol contains extensions that allow for simple authentication to be used within the protocol. This allows the server to determine if the requested action should proceed and whether the connecting user should be allowed to pass based on the credentials provided. The gateway server can then fulfill the request or return an error code to the client indicating a failed action.

Many worm hosts for Code Red were created when Web servers, which people were unaware were in place or vulnerable, were compromised by the worm. This greatly increased the numbers of worm hosts on the Internet. One step in combating the risk associated with network-based worms is to reduce the exposure of services running on any host. Services accept inbound connections from clients, including malicious clients such as worms. An inventory of services and an understanding of them can be used to improve the security of a host attached to a potentially hostile network.
For a large network, this approach can be labor-intensive. However, the payoff can be quite large. For an enterprise network, this can be automated in large measure. By assembling a standard installation, a whole network can be secured in the same manner.

The biggest strength of network black hole monitoring is the relative ease of data collection. Worms that actively scan will constantly generate data as connection requests are sent to these unused networks. Because worms typically do not correlate the use of networks with their probes, most worms will generate probes to unallocated network space.
The largest challenge facing the use of black hole monitoring is the discrimination of regular probes and attacks from activity from worms. This can generally be done by looking for an exponential rise in the number of sources that parallels a rise in activity sent toward the dark network space. However, this typically yields a larger picture of network activity than other monitoring methods do due to the large scale of coverage possible. The intentions of the client computer can be assessed on the basis of the intended network destination.

An additional concern in the possible spread of a worm is the nature of the targets it can affect. Most worms affect only a single or a small number of target types, though it is possible to affect multiple system types in any worm. The complexity of the worm increases for a heterogeneous population of targets. Even on the same architecture, such as Linux on Intel i386 processors, logic must be built in to handle the differences in distributions.
For a worm to have a noticeable impact on the Internet it does not need to affect a majority operating system, either. The Ramen worm, which appeared in 1999 and affected Linux hosts, as well as the Slapper worm, each caused widespread disruptions of the Internet despite the small fraction of Linux installations compared to Windows hosts.

The list below offers tips on what you should do:
• Have real users test your software product. You may think you have created an easy-to-use intuitive piece of software, yet in the end it is not you who decides this. If you plan on selling software online successfully, you need to have real people test it to see how quick they understand how it works and learn how to use it.
