NETWORK ADMINISTRATOR ASPIRING
IT professionals who
work as system or network administrators can benefit from an improved
understanding of what current and prospective employers want from those
interested in such work. In this article, you'll take a look at relevant
certifications, technical skills and knowledge, higher education, and subject
matter expertise of greatest interest to employers seeking to hire network
administrators.
Network administrators are some of the most
sought-after IT professionals. As businesses, schools, and public services
(hospital, emergency support services, and so forth) become ever more wired,
demand for skilled network administrators has remained surprisingly steady,
even in the current economic doldrums. Things can and do break, and when the
inevitable happens, it's the network administrator who restores the status quo
and enables business to run as usual.
Whether it's installing and maintaining
network services, or managing enterprise-level systems and services, a network
administrator's calm and steady presence is key to the successful day-to-day
network operations.
Network administrators need a unique blend
of highly specialized technical skills along with excellent people skills.
While no candidate is "perfect," the following "wish list"
gives you an idea of what an ideal or "perfect" network administrator
might look like.
Networking Basics: It goes without saying
that network administrators must have a complete and thorough understanding of
the basic principles of networking such as NICs; networking hardware of all
kinds; and, of course, wired and wireless media knowledge to match.
Networking Protocols: An ideal network
administrator understands common networking protocols, especially IPv4 and
increasingly, IPv6 as well.
Operating Systems: Network administrators
understand at least one or more network operating systems for both
desktop/laptop and servers systems. A complete understanding of operating
systems such as Windows (XP, Vista, and Windows 7) and MAC OS are essential for
desktop/laptop systems.
For servers, network administrators should
have a thorough knowledge of Windows Server 2003 and 2008, and other operating
systems such as Linux/Unix and Mac OS X. Linux includes multiple flavors
(RedHat, Ubuntu, and Debian, to name a few), and network administrators need to
be familiar with the various distributions. Superficial knowledge isn't
sufficient when it comes to operating systems. Network administrators are
expected to be intimately familiar with common Oss; and to be able to design,
configure, install, maintain, and troubleshoot server and desktop
installations.
Key Network Services: In addition to
networking protocols, network administrators must understand key network
services including name and directory services, file and print services,
distributed applications, email, HTTP, DNS (and possibly WINS), DHCP, FTP,
IMAP, HTTP, plus others as required.
Technical Skills: Network administrators
not only need to understand the networking services they are responsible for
maintaining. They also need practical, hands-on technical skills and must know
how to install, configure, maintain, update, and troubleshoot such services.
ISP/Communication Providers: Network
administrators are frequently called upon to interact intelligently with ISPs
or long-haul communication providers. An ideal network administrator candidate
will not only understand but be able to work with VPNs, encryption,
authentication, and security services to establish safe, usable connections
with the Internet and external service providers.
Project Management: Ideal network
administrators possess project management skills sufficient to enable them to
work with users to provide appropriate network services; identify and deliver
required technical training; plan for and ensure that adequate technical
support is available; and perform capacity planning and needs analysis to make
sure that applications and services delivered meet user and organization requirements,
present and future.
Education: Network administrators ideally
have some formal training in network systems. Education can range from formal
degrees to certificate programs. Owing to the rise (and flexibility) of
eLearning, on-line, and other distance learning programs, certifications and
degree programs, while still requiring time and hard work, are attainable for
those motivated to become network administrators or who want to hone their
skills. Some of the types of programs available include the following:
Degree: Many employers look for network
administrators who possess a degree in computer science, information science,
or management information systems (MIS). While some employers accept degrees in
other fields, they generally look for supplemental computer courses, IT
certifications, or demonstrated (and easily documented) skills and experience
in network administration.
Certifications: Gone are the good old days
when people learned skills in-house and formal training wasn't required! Employers
not only look for certs; they expect them, and most network administrators
don't disappoint. It's common to find network administrators who possess one or
more certifications. Some common certifications include Microsoft Certified
Technical Specialist (MCTS), Microsoft Certified IT Professional (MCITP), or
the Cisco Certified Networking Professional (CCNP).
In-house Training: In today's rapidly
changing technology environment, many companies choose to delay migration and
remain on legacy systems rather than move to the latest and greatest offerings
owing to cost, resource issues, or disruption of day-to-day operations or
services for their users. Or they may be operating on systems specifically
designed to meet their unique needs and that might differ significantly from
systems used by the rest of the world. In-house training specifically designed
for these types of systems is frequently offered in such situations. When
offered, take the training! While it may not be standard, this type of training
can demonstrate the breadth of your knowledge as well as your willingness to
hone your skills, even in areas where most no longer (or never) tread. Plus, it
just may be the skill a future employer is seeking!
Specialty Areas: Technology is growing
exponentially, so many "boldly go where no man has gone before." Such
growth comes with a burning need for network administrators tuned into the
nuances specific to specialty areas. Depending on individual job requirements,
employers look for people with special skills and knowledge in wireless, mobile
wireless, voice over IP (VoIP), network security, storage networking, and
off-beat operating systems or platforms (such as Oracle/Sun Solaris, Novell
NetWare, or even IBM VMS).
IT Equipment Expert: Yes, as a network
administrator you may well become a resident expert on all IT-related purchases
(especially in smaller companies). This expertise can include anything
computers; to operating platforms; to software, hardware, and peripheral
equipment such as printers or displays. Network administrators should be well
versed in evaluating equipment as it relates to the needs of the company and be
able to make appropriate recommendations (you might even be asked to maintain
site licenses).
As network technology continues its forward
march, the demand for highly skilled, highly capable, and highly qualified
network administrators remains steady and ongoing. Ensuring that your skillset
meets current requirements is key to a future as a successful network
administrator. Education is also critical to keeping skills up to date in a
rapidly changing IT world.
In addition to the certifications mentioned
above, you can obtain a certification in almost any area of network
administration that interests you—including security, mobile networks, or
operating systems, to name a few. It's also worth noting that certifications
come in various flavors, ranging from basic skills to intermediate and advanced
or expert skills. If you currently have only basic level certifications,
consider upgrading to an intermediate or advanced level cert.
http://www.gocertify.com is an excellent
resource for certification news and information. It offers articles, blogs,
training, information, freebies, and more. If that doesn't satisfy you, a
simple Google search for "network administrator certification" will
provide you enough hits to keep you busy until Christmas—in 2020!
If you need help narrowing your list,
additional certifications (depending on your areas of interest) worth
considering include 3Com Certified Wireless Specialist, Check Point Certified
Security Administrator (CCSA), SNIA Certified Storage Professional (SCSP),
Sniffer Certified Professional (SCP) EC-Council Network Security Administrator
(ENSA), and Certified Wireless Network Administrator (CWNA). Note that this
list is just the tip of the iceberg. No matter what your particular need or
area of interest, there is a certification out there for you—just look!
Whether you're looking for an entry-level
job in network administration, seeking to move to a new position, or simply
trying for a promotion within your own company, it's good to understand what
employers want as they search for an "ideal" candidate. A good way to
do this is simply to peruse job descriptions and see what types of skills are
required and what skills are preferred, and then evaluate your own skillset in
comparison. If you have a particular company that you're targeting for a
"dream" job, scope out its job descriptions and determine exactly
what is wanted.
Knowledge is powerful. If you know what
employers are looking for, you can give them what they seek. Once you have the
necessary skills, make your resume accurately reflect not only your
professional work history but also your education, certification, and technical
skills. It does no good to have all the right experience and credentials if a
prospective (or current) employer can't tell!
Selling yourself in a resume is quite
different from the personal encounter that face-to-face encounters provide.
