Implement Basic Networks and Security

The use of networks in daily working life is becoming more and more widespread. Many organisations would be unable to operate without computers and networks. This reliance on networking technology means that networks must be robust and work effectively.

Networks are becoming even more powerful and offer many sophisticated and advanced features to users, such as Voice over Internet Protocol (VoIP) where an organisation's telephone service is delivered over the same infrastructure as the network.

There is now great demand for technical expertise in setting up and maintaining networks and also for making sure that networks are secure. There is an ever increasing threat to networks from various sources, including hackers, virus writers, and identity fraudsters among many others. The people carrying out these malicious activities are constantly learning new ways of attacking networks. Because of this technical staff must continually update their skills in protecting networks.
