This area of I.T. is possibly one of the most sweeping and extensive there is. Normally, some degree of specialisation is needed, because to learn about every element would probably take decades of training. Cisco and Microsoft are the two major vendors ruling this sector. The Network & Server software is looked after by MS, while Cisco are mainly responsible for routers & data-switches, in other words the Network hard-ware. Security has grown to be a big problem in recent years, which has forced both businesses to get in to the area in a massive way. An additional fast growing market within this sector is wireless-connectivity and related products. Even though Computer Forensics and 'Ethical-Hacking' have fingers in all these sectors, they are also disciplines in their own right, and demand substantial training and experience to be fully effective.

'CompTIA' (the Computing Technology Industry Association) is a world-wide enterprise that now offers a number of the most reputed vendor-neutral certification tracks available. Organisations like ISC2 provide Security qualifications, and CWNP offer specialist wireless-networking paths. Obviously, there is a whole slew of accreditation tracks from Cisco & Microsoft. The choice might be somewhat over-whelming, & so we advise you to tread carefully and go through all of your plans with an expert who knows the procedure well. This will stop you from making an expensive mistake, both in terms of time and money spent.

Certifications within this market aren't confined to the vendors themselves. In actual fact, there's a wide range of accreditation that's presented by very well regarded unbiased establishments -- & this has grown to be more and more significant. The significance about understanding converging technologies and inter-connectivity in networks has become solidly appreciated. There are right now a number of significant shifts taking place in the world of networking - attitudes in general are leaning towards greener I.T., and both processing-power & data storage are switching towards 'cloud' computing. 'Green' I.T. doesn't particularly signify 'saving-the-planet' -- it does have many elements designed to minimise CO2 impact and so on., but it is also solidly placed in the economic reality of cost reduction. The processing power in modern computers is lower, which means there's less heat to cool down. These two things together vastly cut down the electricity expenditure, & so affect a corporation's bottom-line - especially in data centres and high volume processing departments.

MS produce numerous specialisations within MCSE, for instance in Messaging or in Security for all those who have a special interest. It may be that CompTIA Security+ is right for you, so that you can lead on to the CISSP - 'Certified Information Systems Security Professional'. CISSP prospects have to have considerable professional work experience, therefore be sure to research this well. Our long-standing advice is of course to have an informed discussion before embarking on any new career training.

To most people considering coming into IT as a career, basic-networking could be the starting-point. Practically nothing else will make sense until you've developed a grasp of just how PC's run and connect to one another. If you already have good literacy skills, you will find programs that include CompTIA's A+ and 'N+' provides you with a very good grounding to start your career. We have extensive details about these programs on our section dedicated to 'CompTIA'.

Moving on from here is often the domain of the Microsoft MCSA or MCSE or perhaps the 'Cisco' 'CCNA'/'CCNP', depending on whether you are pursuing the hardware or software side of the equation. Having said that, a good understanding of Microsoft's operating-systems is highly valuable as they're such a vital aspect of the majority of networking environments. You can find further qualification information on this web-site in the specific Microsoft and Cisco pages.

Another option is to continue with CompTIA qualifications for instance Server+ , Security+ or Linux+ & remain vendor neutral, or even take the CWNP or CWNA & specialise in wire-less technologies.

Of course, Computer or Digital Forensics is a newer term that's been popularised via TV shows like "CSI: Crime Scene Investigation". There may well though be a touch less glamour with the actual work when compared with that carried out by the characters on television! Having said that, technological-forensics is providing an intriguing job for a lot of professionals right now. A Computer Forensics expert will search for and interpret digital-artefacts that can often be used to resolve offences.

Alongside Security & Digital Forensics the relatively new field of Ethical Hacking is developing. These are qualifications offered by the EC Council that teach advanced students the darker concepts of hacking - but with the intention of employing these abilities to protect and raise the security within a system, instead of harming it.
