This field is among the largest and most all-encompassing sectors in the world of I.T. Typically, some level of specialisation is required, since to cover every element might take too many years of training. The key systems 'players' in this marketplace are Cisco & Microsoft. The actual software program side of networking is MS's department, & the hard-ware side (routers, controllers and switches and so on.) is where Cisco primarily function. 'Security' has grown to be a big problem recently, which has led both vendors to move into the area in a massive way. We also needs to note the greater commercial use of Wi-Fi today, which is basically wireless connections and hardware. And next we have the dark art of Hacking (legitimately) and Forensics - both of which are complex & incredibly specialised disciplines themselves, and take a great deal of expertise and understanding.

Computer (or Digital) Forensics is reasonably new to the picture - Television shows such as Crime Scene Investigation might have brought it to our attention. There could though be a touch less glamour with the actual work compared to that carried out by the actors on-screen! However for many people, it provides a very intriguing and rewarding role in technology-based analysis. The basic principle being to gather & analyse 'digital footprints', to supply evidence in either a criminal or a civil enquiry.

Together with Security & Digital Forensics the somewhat new role of Ethical Hacking is emerging. These are qualifications offered through the EC-Council that teach more advanced students the more dark concepts of hacking - but with the goal of employing these skills to protect & raise the security within a system, rather than harm it.

Some of the very best industry-acknowledged qualifications now come from the vendor-neutral 'Computing Technology Industry Association' ('CompTIA'). Organisations like 'ISC2' offer 'Security' qualifications, and CWNP offer professional wireless-networking tracks. Clearly, there's a complete slew of accreditation programs from Cisco & Microsoft. Mainly due to the range & quantity of certification paths on offer in this field, its wise to discuss this kind of career move with a professional expert. This will keep you from making an expensive mistake, both in terms of money & time spent.

If you happen to be particularly interested in 'Messaging' or 'Security', then Microsoft have speciality MCSEs on offer to target these areas. You might choose to opt for Security+ with 'CompTIA', followed by the 'Certified Information Systems Security Professional' (CISSP). Before you choose this path though you ought to be aware about the exact level of professional experience needed for the 'CISSP'. As usual, we suggest that you speak with an experienced IT training advisor to avoid any 'mishaps'.
