This area of IT is perhaps just about the most sweeping and comprehensive there is. Generally, some level of specialisation is required, since to cover each component would take decades of studying. Cisco & Microsoft are essentially the 2 main organisations dominating this particular sector. Microsoft produce Network and Server Software, whilst Cisco concentrate mainly on the hardware side of Networking: Routers, switches, controllers and so forth. 'Security' has become a big problem in recent years, which has led each of the businesses to move into the sector in a huge way. An additional fast growing market in this field is wireless-connectivity & devices. Although Computer Forensics and Ethical Hacking have feet in all of these areas, they are also disciplines unto themselves, and demand substantial instruction and experience to become entirely effective.

Computer (or Digital) Forensics is comparatively new on the scene - Television shows such as 'Crime Scene Investigation' could have familiarised us with the term. Clearly though the actual work in actuality will not always be quite as stylised as the programmes might have us believe! Having said that, technological forensics provides an intriguing occupation for a lot of professionals today. The role involves searching for & interpreting 'digital-footprints' for use in data-recovery or legal cases.

Alongside Security & Computer Forensics the relatively new field of Ethical Hacking is emerging. These are accreditations supplied by the EC Council which teach more advanced students the dark concepts of hacking -- but with the purpose of employing these skills to safeguard and raise the security of a system, rather than harm it.

Certifications within this sector are not confined MS & Cisco themselves. Actually, there is a great deal of accreditation that is provided by extremely respected independent organisations -- and this has grown to be more and more significant. An understanding of network interface-connectivity between & within networks is now becoming more and more important. There are today some significant changes going on in networking : attitudes in general are leaning towards greener IT, & both processing power and data storage are shifting towards Cloud computing. 'Green' IT doesn't particularly indicate environmentally-friendly -- it does have many elements intended to minimise the carbon dioxide impact and so on., but its also strongly installed in the commercial reality of cost reduction. Computers generate less heat (& so require less cooling) when they have lower powered processors. Corporations with substantial computer networks can reduce their electricity costs significantly with greener & much more efficient PC's.

Several of the best industry-acknowledged qualifications today are produced by the vendor neutral Computing Technology Industry Association ('CompTIA'). Companies such as ISC2 provide 'Security' qualifications, & CWNP supply professional wireless-networking tracks. Of course, there's a total slew of accreditation programs from Microsoft and Cisco. Mainly because of the range & number of accreditation routes to be had in this field, it's wise to talk through this kind of career change with an experienced expert. You might save a good deal of money and time, as well as frustration & discouragement.

For most people checking out getting into IT as a profession, basic networking is the starting point. You must know how PC's operate and communicate with one another before you can do anything else. As long as you have decent literacy skills, you'll find programs that include CompTIA's A+ & N+ will give you a very good grounding to start out on your career path. They're dealt with on the 'CompTIA' section on this website.

Moving on from this level will often take you to the MS 'MCSA'/'MCSE' or the 'Cisco' CCNA/CCNP, based on whether you're interested in the hardware or software end of things. However, an in-depth knowledge of MS's operating systems is highly advantageous as they're such an important element of most networking-environments. You can find more qualification details on this site from the specific Microsoft & Cisco pages.

Alternatively, you might choose to remain down the vendor-neutral track with further CompTIA qualification (for example Security+, Server+ & Linux+ ) or possibly try your hand at the wire-less (Wi-Fi) side of things with the 'CWNP'/'CWNA'.
