This area of IT is perhaps just about the most sweeping and comprehensive there is. It could take many years to become an authority in all elements, and so specialisation is essential to some extent. The chief systems 'players' in this market are Microsoft and Cisco. The Network and Server software programs are looked after by MS, whilst Cisco are mainly responsible for routers and switches, i.e. the Network hard-ware. It's become financially and economically necessary for Microsoft and Cisco to move into security over the last decade. Another fast-growing market in this field is wireless connectivity & related products. Although Computer Forensics and 'Ethical-Hacking' have fingers in all these areas, they are also professions unto themselves, and require substantial instruction and real-life experience to become fully effective.

The vendor neutral world-wide organisation 'CompTIA' now provides perhaps the most recognised & widely respected independent I.T. certifications. Organisations like ISC2 supply Security certifications, & 'CWNP' provide professional wireless-networking paths. Naturally, there is a comprehensive slew of accreditation sets from Cisco and Microsoft. Largely because of the range & level of accreditation tracks on offer in this sector, it's very wise to discuss this kind of change of career with an experienced expert. This will likely keep you from getting into a costly mistake, in terms of time and money spent.

Recently, Digital or Computer Forensics is a newer expression that's been popularised by TV shows such as "CSI". Clearly though the role in real life won't always be quite so stylised as the shows might have us believe! Nevertheless for many people, it offers a very interesting and satisfying role within technology-based analysis. The job involves seeking & interpreting digital-footprints to assist with data recovery or legal investigations.

Along with Security & Computer Forensics the relatively new field of Ethical-Hacking is emerging. The Certified Ethical Hacker (CEH) and the Computer Hacking Forensic Investigator('CHFI') are medium to advanced level certifications offered through the EC-Council.

If you happen to be particularly focused on 'Messaging' or Security, then Microsoft have speciality MCSEs available to handle these options. You might decide to opt for Security+ with CompTIA, and then the Certified Information Systems Security Professional ('CISSP'). You'll find there are stringent experience requirements for the CISSP, and they need talking about and getting to grips with before you take this path. Talking things through with one of our team of it training experts will explain everything for you.
