This area of I.T. is possibly just about the most sweeping & extensive there is. It would take decades to train to become a specialist in all aspects, & so specialisation is essential to some level. Both Microsoft and Cisco make systems to operate in market place. The actual Network and Server software programs are made by MS, whilst Cisco are mainly concerned with routers and data-switches, that is the Network hardware. It has become commercially necessary for both MS and Cisco to move into Security during the last several years. Another fast growing area in this sector is wireless connectivity & related products. Although Digital-Forensics and Ethical-Hacking have feet in all these areas, they are also disciplines unto themselves, and require considerable instruction & experience to become entirely effective.

'CompTIA' (the 'Computing Technology Industry Association') is a worldwide enterprise that currently provides many of the most reputed vendor neutral certification paths available. Companies such as 'ISC2' provide 'Security' qualifications, and CWNP supply specialist wireless networking paths. Most conspicuously needless to say are Cisco and Microsoft themselves, both with their very own qualification tracks. The choice might be rather mind-boggling, and so we advise you to go cautiously & talk through your alternatives with an expert who knows the process well. You could possibly save a lot of time and expense, as well as frustration and discouragement.

MS produce a variety of specialist areas at MCSE level, for instance in Messaging or Security for all those with a specific interest. It may be that CompTIA Security+ would be best for you, so that you can lead onto the CISSP - Certified Information Systems Security Professional. 'CISSP' applicants must have substantial professional working experience, so make sure you research this thoroughly. As usual, we advise a discussion with a knowledgeable IT training advisor to avoid any kind of 'mishaps'.

You might have noticed that Computer or Digital Forensics is a frequently used term that's been popularised by Television shows like "CSI: Crime Scene Investigation". There may well though be a touch less glamour regarding the real work compared to that done by the actors on our screens! Even so, technological forensics provides a fascinating career for a lot of individuals today. The job entails seeking & interpreting 'digital footprints' to assist with data-recovery or legal investigations.

Together with Security and Digital Forensics the relatively new profession of Ethical Hacking is developing. Experienced I.T. professionals can study the principles of 'criminal' hacking for legitimate ethical security purposes. The EC-Council delivers medium to high level certifications, namely the 'CEH' ('Certified Ethical Hacker') & the 'CHFI' ('Computer Hacking Forensic Investigator').

For many people looking at coming into I.T. as a career, basic-networking could be the starting point. Before you are aware of just how a PC functions and 'communicates' with other Computers, anything more is simply nonsense. Presuming at least a basic level of computer user skills, (read the general IT Training web-pages if not,) the starting-point is almost always 'CompTIA' A+ and CompTIA Network+ . Examples of these are dealt with under the 'CompTIA' pages of this site.

Moving forward you'll choose to follow the MS MCSE or MCSA track if you're interested in software, or the 'Cisco' 'CCNA' or 'CCNP' track if you are considering hardware. Nevertheless, Microsoft has a major domination in most network environments, which means an in-depth understanding of their 'software' is actually very relevant whatever you specialise in. You can get further qualification information on this site from the dedicated MS & 'Cisco' sections.

Equally of course you may choose to fine-tune your Wi-Fi (wireless) skill-sets by taking qualifications such as the CWNA and CWNP, or carry on down the CompTIA track with Security+ , Linux+ or Server+ .

Certifications in this field aren't confined MS & Cisco alone. In fact, some well respected institutions are essential players now where accreditation is concerned. It is now widely recognised that understanding inter connectivity & technological-convergence has become extremely fundamental in networking. Networking is in fact going through some major paradigm shifts at the moment; perceptions generally are inclined towards greener IT, & both processing-power & data storage are switching towards 'cloud' computing. From the financial viewpoint, 'greener' engineering has to be built to be much more cost-effective, in addition to being kinder towards the planet. Lower-power processors & computers create much less heat, therefore much less cooling is needed. Organisations with large networks of computers can reduce their fuel expenditure substantially with 'greener' and more efficient computer systems.
