This area of I.T. is perhaps just about the most sweeping and extensive there is. Normally, some level of specialisation is needed, since to cover every element might take decades of learning. The major systems contributors in this market are Microsoft and Cisco. The Network & Server software is produced by Microsoft, and Cisco are mainly responsible for routers and data-switches, in other words the Network hard-ware. Each of the vendors have branched seriously in to Security during the last several years, by economic need. Another fast growing area within this sector is wireless connectivity and related products. Although Digital Forensics and Ethical-Hacking have fingers in all these sectors, they are also professions in their own right, and require substantial training and real-life experience to be fully effective.

There are a variety of speciality MCSE's from MS, that offer areas like Messaging or Security if that is the direction you would like. You could possibly decide to look at Security+ from 'CompTIA', and follow that with the Certified Information Systems Security Professional ('CISSP'). You'll find there are rigid experience specifications for the CISSP, & these need talking about and understanding prior to deciding to go down this track. Our long-standing advice is always to take part in an educated discussion before getting into any new career training.

The vendor neutral world-wide association CompTIA now delivers perhaps the most familiar and widely-respected impartial I.T. qualifications. Companies such as ISC2 supply Security qualifications, and CWNP supply specialised wireless networking paths. Obviously Cisco and Microsoft offer a complete array of professional level accreditations. Because there are so many training and employment possibilities in this sector, its advisable to get more personal help and advice from an experienced industry advisor prior to choosing your particular track. This will likely keep you from getting into an expensive mistake, both in terms of time & money spent.

If you're planning to build a career in I.T., start by developing some networking know-how. Before you understand the way a PC functions & communicates with other PCs, anything else is nonsense. Presuming at least a basic level of PC literacy, (refer to our general I.T. Training pages if not,) the starting-point is nearly always the 'CompTIA' A+ and CompTIA Network+ . Examples of these are included within the CompTIA section of this web-site.

Moving on from here will often take you to the Microsoft MCSA or MCSE or perhaps the 'Cisco' CCNA or CCNP, depending on whether you are interested in the hardware or software side of the equation. Nevertheless, an in depth knowledge of Microsoft's operating-systems is extremely useful as they're such an important element of the majority of networking environments. You will get additional accreditation details on this web-site from the specific Microsoft & Cisco pages.

Of course you could enhance your Wi-Fi (wireless) skill-sets by taking certifications like the 'CWNA' and 'CWNP', or carry on along the CompTIA route with Linux+, Security+ or Server+ .

There are now broader alternatives in addition to Microsoft & Cisco to become accredited in these sectors. Several well respected neutral organisations are today offering increasingly more relevant & essential qualifications. It's now become extensively recognised that knowledge of inter connectivity & technological-convergence is becoming very important in networking. There are right now some considerable changes occurring in networking - both in terms of processing & in data-storage, with internet based computing coming to the fore & 'green IT' growing to be more and more relevant. 'Green' IT doesn't specifically mean 'saving-the-planet' - it does have elements intended to lower the carbon dioxide impact and so on., but it is also strongly installed in the commercial reality of cost reduction. The actual processing-power in more technologically advanced computer systems is lower, which means less heat to be cooled down. Organisations with substantial networks of computers can bring down their electricity costs substantially with 'greener' and much more efficient computer systems.

More recently, Computer or Digital Forensics is a frequently used term that's been made popular through Television shows like "CSI: Crime Scene Investigation". There may well though be a bit more routine regarding the actual work than that carried out by the actors on television! Nevertheless, technological forensics is providing an intriguing profession for many individuals these days. The work entails seeking & interpreting 'digital footprints' that can be used for data-recovery or legal investigations.

Together with Security and Computer Forensics the somewhat new role of Ethical-Hacking is emerging. These are accreditations provided through the EC Council which teach more advanced students the dark principles of 'hacking' - but with the intention of using these abilities to protect & raise the security within a system, instead of damaging it.
