So you want to learn how to become a network administrator. This could be your next step towards a challenging, fulfilling and rewarding career in the information technology field. The future looks bright for this career – in 2006 the Bureau of Labor Statistics estimated that the field of network administration will have grown by 18 percent by 2016, adding 155,000 new jobs. As a network administrator you can manage online functions, local area networks and wide area networks for businesses, government agencies and/or nonprofit organizations. But before anything else you will need to get some education and training.

Most network administrators enter this career after getting a bachelor’s degree in computer science, although there are other degree options. If you get an associate’s degree in computer science or a bachelor’s degree in a related field like math or engineering, but you have taken computer classes and earned the most sought-after certifications, you should still have a bright future in this industry.

Whatever educational path you take, it also really helps to complete an internship program while you’re in school. This way you’ll have some experience to boost your résumé, and you may even get a job at that company once the internship is over.

Once you have gotten your education and training out of the way, then you need to update that résumé to include all your experience and start applying for jobs. If you weren’t able to get hired at the company you interned at, try to see what kind of services your school’s career center offers. There are also online job boards geared toward network administrators and other tech jobs. You may also find some part time, temporary or freelance positions that are immediately available if you can’t find a full time job in this field right away.

It’s never been a better time to be a network administrator. The salary range for network administrators in the United States is ,520 to ,000 per year, according to the Bureau of Labor Statistics. With experience and merit there’s no reason why you can’t earn a salary in the top of that range.

In the field of Computer Networking support, the specializer area of network security consists of the plannings and policies adopted by the Computer network administrator and networking consultant to prevent and monitor without official authorization access, misuse, modification, or denial of the computer network and network-accessible resources.

Network installation service and security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users (also known as “intruders”) from accessing any part of your computer system. Detection helps you to determine whether or not someone attempted to break into your system, if they were successful, and what they may have done.

The term network security refers to steps taken with the intention of protecting your computer and data network of threats from Trojan horses, worms, viruses, ad ware, hacker attacks, spyware, denial of service attacks, identity theft and theft by data interception.

In short, network support services measures are implemented to protect the computers in your office by ensuring their integrity, reliability, usability and safety of your computer network and data.

Effective network security targets a variety of threats and stops them from entering or spreading on your network.

Implementation of Network Security
To better understand its implementation, let us consider a hypothetical example. Let us assume a new Fort Knox was being setup and you were in charge of its security.

How would you go about ensuring the security of the vault and the bank in general?

You would probably want to start at the vault itself by building one of solid steel or titanium having three feet thickness or so. The thickness would make it impervious to drilling or even powerful blasts. Then you would probably install movement detectors, heat detectors and tremor sensors. For the vault door itself you would probably want to use the world’s best locking system controlled by two or more authorized personnel. Moving one layer ahead, you might consider it a good idea to have a posse of security guards to prevent all but only authorized personnel from approaching the vault and so on. In other words, you would rely on several measures implemented like layers of an onion. And that is also exactly how computer network and data security measures are implemented – there is no one particular software or hardware rather, it is several measures implemented at several levels.

All these measures need to be reviewed no less than once a year because hackers and malicious software creators quickly learn how to bypass your security measures by hard work, sheer ingenuity and lots of skill. Computer network even includes your peripheral and communication devices. Hackers are known to routinely hack into the telephone network, pretend to be an authorized employee and phone up the system administrator to request that the password to a certain computer or wifi router be reset. A few seconds is all it takes for the hacker to get into your computer system.

Network security services and measures include but are not limited to installation of up-to-date anti-virus and anti-spyware, anti-adware, properly configured state-of-the-art firewalls, intrusion prevention systems and virtual private networks (VPN’s), to ensure secure remote access.

Major Benefits of Network Security
A good network security ensures that your company meets the mandatory regulatory compliance because network security helps protect sensitive data and reduces the risk of legal action from affected parties due to data theft. Network Security also saves your company a lot of embarrassment by not getting bad media attention that follows any security breach, it also protects from unwanted (and usually expensive) disruptions. Ultimately, network security ensures the protection of your most important asset – your business reputation.

By description, this is a protocol designed for transfer of time around a computer network. It works through a hierarchy composed of several strata starting with Stratum 0 which provides the external source of time. Stratum 1 gets the accurate time from a hardware clock which can be got through GPS signals as they are the safest and most reliable. This is because of the many satellites that orbit the earth at any one time. The references are not limited to these as radio signals and broadcasts also provide a safe and relatively reliable source of time. The broadcasts vary with locations and are not as centralized as the GPS signals but they all provide related times, if not equal. Some common ones include MSF from the UK, JJY from Japan and WWVB from the USA.

Reliability being the main issue means that there is need for backup reference clocks in the unlikely event of a signal outage.

These references provide the time with the same precision as the signals and are able to maintain a holdover for extended periods until the signals are regained. These backups are expensive however and the reasons for getting them should be more than the reasons for foregoing them. If you decide you need them to maintain the time then there are crystal oscillators that come at a good price.

NTP client software is usually provided with most OS. Linux has GNU public licence NTP client while Windows has Windows Time service. The advantage of having NTV servers is that is to make sure that the time-stamped transactions are carried out in the specified order. They are the missing link between network time distribution and the global time scale and should be an integral part of any company or organization.

The expansion in networking correlations, convolutions and commotions has been followed by an increase in the amount of transgressions perpetrated within the networks. This has compelled the venture and law enforcement to embark on highly focused and specialized enquiries. Forensic scrutiny is the systematic analysis of a crime scene that creates unusual hitches and complications in the imaginary world. The main issue for an examiner within a computer is making some logic out of delicate digital data structured in vague and convoluted manner within the extensively large digital framework of the network.

Network forensics or Computer Forensics is the arrest, footage, and scrutiny of network events in order to identify the origin of security attacks. It assists in discovering unlawful admittance to a computer system, and hunts for proof in case of such an event.

Network forensics is the skill to scrutinize, at a network level, events happening or that have already occurred across an IT system.

There Are Three Steps To Network Forensics:

Intrusion Detection

Logging is the most excellent means to trail a hacker is by recording and preserving vast records of motion on a network with the help of an intrusion detection system.

Correlating Intrusion Detection And Logging

The utmost objective of network forensics is to present satisfactory evidence to let the illicit executor to be effectively put on trial. The realistic implementation of Network Forensics could be in areas such as hacking, deception, scam, insurance companies, data theft—industrial spying, denigration, narcotics trafficking, credit card replicas, software piracy, electoral law, obscene publication, false swearing, massacre, sexual harassment, and prejudice.

The most challenging part whilst performing network forensics is the thorough quantity of data produced by the network, mostly covering gigabytes on a daily basis. It becomes very monotonous to seek for facts and sometimes becomes nearly impossible to discover one, especially if the event is exposed after a very long time. Fortunately, the broad range of potent software, counting products rationale-built for forensic analysis, makes it convenient and realistic to crack cases.

Building a computer network in your large home with two storey building is more difficult compared with a home with only one floor building and is sometimes frustrating. Thick concrete building generally contributes signal attenuation and dead spots in wireless. Running network cable is a hard work. But Powerline Ethernet adapter helps you build the network easily.

Should you build a home computer network from the scratch which consist of first floor where your Cable / DSL internet connection starts and the second floor where you would like to Expand the network wirelessly, you should assess your requirements to meet your needs. On the first floor, how many computers you need, how you connect them – wired or wireless. On the second floor, this is important because you need to connect the first floor to the second floor where a thick concrete building will be an obstacle whether you run the network cable or wireless access.

In the first floor where your router gateway (with 4x Ethernet ports) is located connects two desktop computers which are close each other with the gateway router – a wired connection for each of the computer is easier.

You just need to run a network UTP cable from each of the desktop computer to the router Ethernet ports.

Now the challenge is how to connect several laptops with Wi-Fi enabled and other Ethernet based devices in the second floor to allow them connect and access the Internet? You have two options – you run a network cable from the first floor to the second floor, or you provide wireless access from the first floor to the second floor clients. To run a network cable from the first floor to the second floor you need an extra effort probably by drilling the hole or run the clutter of the wires that will just look untidy.

You can install a wireless access point in the first floor and allow client computers in the second floor connect wirelessly.

But with the thick concrete building between the first and the second floor the wireless signal strength received by client computers in the second floor would be considerably weak. Your wireless performance in the second floor would be unsatisfactory.

The easiest way for your home computer network with two floors like this is to install a Powerline Ethernet adapter in the first floor and another adapter in the second floor. With Powerline Ethernet adapter, you can create high-speed secure building wide network using the power outlets in a single circuit breaker. The TPL-401E2K Trendnet Powerline Ethernet adapter is a new high speed adapter delivering the speeds of up to 500Mbps (theoretical) via the power outlets.

In this case, you can install one TPL-401E2K in the first floor and connect to the Ethernet port of your router gateway. And then you can install other Powerline adapters in each of the available power outlets in home as necessary to meet your need. Install one adapter in the second floor where you would like to install the wireless access point.

What this TPL-401E2K Does

Trendnet TPL-401E2K Powerline Ethernet Adapter is a high speed adapter via power outlets delivering the speeds of up to 500Mbps (in ideal conditions). The adapter is equipped with one Gigabit Ethernet port which is ideal in delivering high speed applications such as streaming High Definition (HD) media and smooth gaming. You can deploy up to 16 adapters in a network. For security connection, the adapter supports advanced 128-bit AES data encryption.

One thing to remember in deploying the Powerline Ethernet adapters in a building is that the adapters must be in a single circuit breaker system. If there are two circuit breaker systems in your building, to cover the whole building network you need to make a link between the circuit breakers. You need to install one adapter in one circuit breaker and another adapter in the other circuit breaker and link them as a bridge.

Now you can successfully build your home computer network providing wired connection in the first floor and wireless access in the second floor using the TPL-401E2K Powerline Ethernet adapter as a bridge between the floors via power outlets eliminating the clutter of the wires.
