How do you know what your customers want? Perhaps you should ask them.

Surveying your internal or external customers gives you hard information on which to base decisions about product development, marketing campaigns, resourcing or any other area where you organisation or department interacts with another group (which means in nearly everything you do).

Considerations when designing or specifying an on‑line learning environment.

For many organisations, the provision of training to staff and customer represents a significant cost. As the processing power and network bandwidth available to desktop PCs increases, the performance and features of on‑line learning systems have improved to the point where the delivery of training via a computer has become a viable option.

While on‑line learning is not an appropriate solution for all training needs, it does provide an effective training delivery mechanism in the right circumstances.

This article discusses some of the issues involved in creating an on‑line learning environment, viewed from the perspective of the different interest groups involved. The information and concepts shown here are not definitive; you should carefully consider your own specific requirements before implementing any computer system.

You shouldn't be using open source software because it's cheaper (although it is), you should be using it because of its features and flexibility and the fact that it doesn't lock you in to restrictive license agreements.

The widespread commercial use of the internet has led to an increasing focus on systems security. Media driven hype and a lack of independent information can make the true level of threat to an organization difficult to determine. Adopting a structured approach to the analysis of computer system security risks and allows an organization to more effectively balance their operational requirements against the potential for loss, whether that loss involves physical equipment, information or reputation.

This article discusses the components of a computer system, the types of attack to which they are exposed, some typical defence mechanisms and some weaknesses in the standard defences. The information and concepts shown can form a starting point for the development of suitable security and operational strategies to assist organizations to obtain the maximum value from their investments in computer systems.

It might be the last thing you want to read, but not having a well documented IT infrastructure (servers and networks) can lead to surprising events like critical systems running on unsupported servers.

Documentation must not only be accurate at the time it was created it should also meet these additional criteria:

• Available The people who need the information must be able to get at it.
• Editable Any documentation in the IT industry is quickly out of date, so it is essential that information is able to be correctly updated as soon as a change is required. Ideally the client or end-user should be able to do this, rather than waiting on the 'approved editor'.
• Current 'Out of date' is just a nice way of saying 'wrong'. The date on which the underlying information was updated should be shown on any reports either printed or viewed online.

External Network Scanning

One of the core mechanisms for protecting networks is to install a firewall to mediate traffic between systems on the internal network, publicly accessible systems is a DMZ (from the military term demilitarised zone) and the internet.
