Of all the I.T. areas dominating the global stage, this field is one of the biggest and most all encompassing. It could take far too long to train to become a specialist in all aspects, and so specialisation is vital to some level. Both Cisco and Microsoft create systems for this market. Microsoft produce Network and Server software, whilst Cisco concentrate primarily on the hardware end of Networking: Routers, data switches, controllers etc. 'Security' has grown to be a huge problem recently, which has forced both vendors to get into the sector in a massive way. Equally in this field we're seeing the substantial development of wireless-networking. Even though Digital-Forensics and Ethical-Hacking have feet in all of these areas, they're also disciplines by themselves, and demand substantial instruction and experience to become entirely effective.

Several of the finest industry-recognised accreditations today come from the vendor neutral 'Computing Technology Industry Association' (CompTIA). Other bodies also supply valuable qualifications, like CWNP (Certified Wireless Network Professional) and 'ISC2' (International Information Systems Security Certification Consortium). Obviously, there is a complete variety of accreditation tracks from Cisco and Microsoft. The options may well be rather mind-boggling, and therefore we encourage you to go cautiously and discuss all of your plans with an expert who understands the process well. You could possibly save a great deal of time and money, as well as stress & disappointment.

Of course, 'Digital' or 'Computer' Forensics is a frequently used expression that has been made popular by TV shows like "Crime Scene Investigation - CSI". Clearly though the work in the real world will not be quite so stylised as the TV shows would have us believe! Nevertheless for many, it offers a highly intriguing and rewarding role in technology based exploration. A Computer Forensics expert will trace & explain digital artefacts which can often be used to resolve offences.

In a similar arena to Computer Forensics and IT Security is Ethical Hacking - which is another relatively new discipline to manage criminal activity. The 'Certified Ethical Hacker' ('CEH') & the Computer Hacking Forensic Investigator(CHFI) are mid to advanced level accreditations supplied through the EC-Council.

Qualifications within this market are not confined MS & Cisco alone. The fact is, there's a great deal of certification that's offered by highly well regarded unbiased establishments - & this has grown to be increasingly important. The essential knowledge of network-interface connectivity between and among networks is now becoming increasingly important. We are witnessing a significant paradigm shift within network technology today, both in processing terms & in data storage, with internet based computing gaining momentum and 'green IT' becoming increasingly relevant. The development of green I.T. covers 2 important issues - reducing the effect on the planet is one, but possibly of equal importance to business is expense. The processing-power in modern computer systems is lower, which means less heat to be cooled down. Energy expenditure can be considerably reduced for companies such as data-centres that are high technology users.
