This area of I.T. is possibly just about the most sweeping & comprehensive there is. It could take many years to train to become an expert in all factors, and so specialisation is vital to some extent. The chief systems players in this marketplace are Microsoft & Cisco. The actual software program side of networking is Microsoft's department, & the hard-ware side (routers, controllers and switches etc.) is where Cisco mainly work. It has become commercially essential for both MS and Cisco to get into Security during the last decade. We should likewise take note of the more professional use of Wi-Fi now, which is essentially wireless connections & hardware. And then we have the dark art of Hacking (legally) and Forensics : each complex and very specialised subjects themselves, and take a great deal of working experience and understanding.

Certifications within this marketplace are not restricted just Cisco and Microsoft alone. In fact, there is a wide range of accreditation that is supplied by highly respected impartial establishments - & this has grown to be increasingly important. The significance about grasping converging-technologies and inter connectivity in networks has become very well appreciated. Networking is in actual fact undergoing some important paradigm shifts at the moment; perceptions generally are inclined towards 'greener' I.T., & both processing power & data-storage are going towards Cloud computing. The introduction of 'green' I.T. addresses 2 important elements - reducing the effect on the planet is 1, but perhaps of equal or more significance to business is cost. Computer systems generate much less heat (& so require much less cooling) if they have lower power processors. Organisations with substantial computer networks can lower their electricity bills substantially with 'greener' and much more efficient PC's.

To most people checking out coming into IT as a profession, basic-networking is the starting-point. Before you are aware of exactly how a Computer functions & communicates with other Computers, the rest is nonsense. If you already have decent user skills, you'll find training programs like CompTIA's A+ & 'N+' gives you a superb grounding to begin your career. Information about these certifications are featured on the 'CompTIA' pages of this web-site.

Moving on you can choose to go down the MS 'MCSE' or 'MCSA' path if you are interested in 'software', or the 'Cisco' CCNA or CCNP path if you are interested in 'hardware'. That said, MS has a high domination throughout most network environments, therefore an in depth understanding of their 'software' is actually extremely useful whatever your specialisation. As before, you will come across the specifics of each certification on the Cisco and MS areas of this site.

A different option is to carry on with 'CompTIA' qualifications like Linux+, Security+ or Server+ & remain 'vendor-neutral', or maybe take the 'CWNA' or 'CWNP' & specialise in wireless technologies.

Of course, Computer or Digital Forensics is a newer expression that has been popularised through TV shows like "Crime Scene Investigation - CSI". The physical reality of 'Computer Forensics' is much more routine than pictured in these programmes (obviously!) However for many, it provides a very interesting and rewarding role in technology based exploration. A Digital Forensics specialist will search for and interpret 'digital artefacts' that are frequently used to resolve criminal offences.

Seated somewhere between Digital Forensics & Security, is the field of Ethical-Hacking. The Certified Ethical Hacker ('CEH') & the 'Computer Hacking Forensic Investigator'('CHFI') are medium - advanced level certifications supplied by the EC Council.

Microsoft provide a variety of specialist areas at MCSE level, for instance in Messaging or in Security for those with a special interest. You might decide to go for Security+ from CompTIA, followed by the Certified Information Systems Security Professional (CISSP). Before you choose this path though you have to be aware about the amount of professional experience required for the 'CISSP'. As always, we recommend a discussion with a skilled IT training advisor to avoid any kind of mistakes.

The vendor neutral global organisation 'CompTIA' now delivers possibly the most recognised & highly-regarded independent IT qualifications. Establishments such as ISC2 provide Security accreditations, & CWNP offer specialised wireless networking paths. Of course Cisco and Microsoft offer a comprehensive array of skilled professional accreditations. The options could be a little overwhelming, and therefore we encourage you to go cautiously & go through all of your plans with an expert who knows the process well. Without having personally-tailored guidance you could potentially head-off in a wrong direction and squander considerable time and/or money.
