Network Security Sandbox

There is a wide range of network security products available on the market now. Despite these products, certain undetected and ingenious cyber crimes take place by making use of certain evasive binaries. They either make the network security system stop completely or escape from the observance of it. So, a behavioral approach is needed to detect APT (Advanced Persistent Threats) which are based on malware’s activities.

cyber securityMarket Definition by Segment Type

There are three categories of the market for network sandboxing.

1. Standalone

It is implemented independently of existing network security systems. It does not affect any other security system.

2. Firewall/IPS/UTM

It is an optional feature of existing network security and it is implemented in the cloud.

3. Secure web Gateway / Secure Email Gateway

It is an optional feature of the existing security solutions.

Key Factors Driving the Market Growth

Following are the major factors driving the market growth:

Factor 1

The continuous rise of cyber crimes throughout the world

The Data Breach Investigation Report of Verizon in 2015 revealed that there were 79790 secret incidents and out of these, some 2122 cases had confirmed data breaches. These breaches of security took place in different forms such as point of sales intrusion, web app attack, cyber espionage, insider misuse, card skimmers, Desk Operating System attack, crime-ware, miscellaneous errors and physical thefts. In order to tackle the increasing threats, the network security system has to be involved in constant research and innovative tools must be put in force before the criminal attackers breach data, resulting in loss of money and business.

Factor 2

The spear fishing attacks have to be faced

It is an electronic communication scam or an email targeting a specific organization, business or individual to steal data with malicious intentions. The criminals may install malware on the targeted user’s computer. The spear phishing is not a random activity, but a targeted activity by perpetrators with the specific intention for financial gain, military information and trade secrets. The emails to the targets may seemingly look like coming from usually a trusted source, like eBay or PayPal. But the perpetrators can be from the same company of the target in authority as ascertained in most of the cases. Any such spear phishing mail may contain certain inherent characteristics such as seemingly a trusted source, valid reasons for a message and logically acceptable validity.

Factor 3

The adoption of NSS is more prevalent.

The Network Security sandboxes enhance cyber security. In NSS environment, the appliances can execute and inspect network traffic and non-application data, such as Adobe Flash or JavaScript to uncover malicious code. This enables the organizations to identify previously unseen malware or zero-day threats before they enter the network and cause harm to the organization. Thus, sandboxing has proved to be a powerful tool for advanced threat protection and so its adoption is prevalent throughout the world.

Factor 4

The NSS can be integrated into existing platforms

The NSS can integrate with the existing security infrastructure like Firewall, UTM etc and protect, learn, and improve the overall threat protection. It delivers effective protection against any advanced threats. This cutting edge sandbox capacity can be complemented with established defenses, as NSS perfectly integrates with the existing platforms.

How To Choose Cloud Technology For Your Business

Working with a cloud computing company can be beneficial in numerous ways. According to several surveys at the international level, it has been found that companies of all sizes and shapes are adapting such services to improve their working efficiency, enhance their profit margin and minimize the business operational cost. However, most of the people do not have an exact idea about cloud computing.

Read on to understand what is cloud computing and what are the elements you need to take into consideration when selecting a computing vendor for your business.

What is cloud computing?

In order to understand the concept of cloud computing, it is vital to understand where the term “cloud computing” originated from. It is most likely originated from the use of cloud like shape to demonstrate the network computing environment, which include hardware, storage, services, networks and services involved.

You can find several definitions over the internet in the context of cloud computing. It is simply a delivery of software services and computing infrastructure through the internet. People can access shared resources, software applications and system stored on any remote server through the internet browser.

The cloud computing services are usually offered by Third Party companies. Most of the IT companies prefer to hire such firms to reduce their operational cost, improve their working efficiency, maximize their profit margin, and to have a great control over their business.

It is easy to find numerous companies that provide cloud computing solutions for small, mid-sized and large IT firms. However, not all of them offer genuine and reliable services. When going to hire a company, it is important to find a service provider that can meet all your needs. Here are the few elements which you need to take into account when selecting one for your business.

Technical support

When going to hire a service provider the first and foremost thing which you need to check is the IT support services. Check the support services offered by different cloud computing service providers and the ways through which they are available for your help or support such as phone, email, fax, online chat and so on. Besides this, you need to ensure that their support hours meet with your business operation hours. You also need to ensure that their support services are available in weekends, holidays and beyond the office hours during the emergency.

Service Agreements

The professional vendors usually sign business agreements which include the details of their services and commitments such as response time, service hours and the time limit that servers are online. You need to check every term and condition before going to sign any agreement. If possible, request them to make service agreement as per your business need and requirements.

Standard API

It is vital to ensure that the cloud computing vendor you are going to hire is utilizing a standardize application programming interface (API). API is a mechanism which handles the data transmission of a specific application into the cloud. When using a standardize API, you can get a peace of mind that the server will be compatible with your applications.


It is important to know how the cloud vendor will protect your data and important documents. You need to find out the answer of some common security questions like what forms of authentication are used by the vendor, who can access your data? And so on. This will surely help you in choosing the right computing vendor for your firm.

Billing and Monitoring

Not all cloud computing vendors offer the same level of services at the same charges. Their charges may vary depending on the services and facilities they provide to their users. You need to check and compare the facilities and services of different vendors. This will help you in choosing the right company within your budget.

By keeping these elements in mind before hiring any company, will definitely help in choosing the right cloud computing vendor for your business.

Face Off: Virtual Desktop or Remote Desktop?

One of the most critical decisions that companies have to take is whether to opt for a virtual desktop or a remote desktop, or a combination of both. For this, a comparative study needs to be conducted to compare and contrast which option would suit your business needs and functions.

Remote Desktop Connection
Remote Desktop Connection

While both the options have their own advantages and disadvantages, mentioned below is a gist of virtual and remote desktops that will aid you in making the correct decision:

Remote Desktop

Initially known as terminal services, the remote desktop is a Microsoft service that allows users to have a virtual session by accessing files and applications through a server. The experience of using remote services is more or less like using a local desktop; the only difference is that the session is processed on a server not the desktop.

Remote desktops are relatively simpler as little infrastructure requirements are needed to be met; thereby reducing implementation costs. Moreover, it helps in enhancing remote worker’s efficiency because it is most suitable for remote workers, contractors and corporate workers working from a remote location.

However, the biggest drawback of a remote desktop is that it has compatibility issues. Since it has a terminal environment, many applications fail to work. Nonetheless, improvements have been made over the years and many applications have started working, but still some applications do not work till date.

Virtual Desktop

Also known as VDI, the virtual desktops are basically interfaces that run on a virtual environment and not on a local desktop. However, the virtual desktop environment and infrastructure tends to be more convoluted than the remote desktop. The administrators are responsible for managing numerous virtual desktops

Some of the important benefits of a virtual desktop are: the administrators find it easy to adapt or allocate the RAM capacity, disk space and various other peripherals; the data on the virtual desktop can be backed up and easily restored using snapshots; virtual desktops are easily deploy able as it has the capability to replicate and develop templates in a span of a few minutes.

Although VDIs are a costly option, they have the capability to provide numerous benefits that outweigh this drawback.

It is important to understand that both desktops are meant to be operated in a different environment; therefore, your needs and requirements must be matched to the features of these desktop services before deciding which one to go for.

DES and 3DES

Data Encryption Standard (DES) data are encrypted in 64-bit blocks using a 56-bit key. The DES algorithm takes the input through a series of transformations: initial permutation; a complex function, which involves both permutation and substitution operations and depends on a key input; a simple permutation function that switches the two halves of the data; the function is applied again; and a permutation function that is the inverse of the initial permutation takes place. There are five “modes of operation” that have been defined in order to apply DES to a variety of applications. They are Electronic Codebook, Cipher Block Chaining, Cipher Feedback, Output Feedback Counter, and Counter (Cryptography Concepts, 2005).

Triple DES or 3DES involves repeating the DES algorithm three times on the plaintext, using two or three different keys to produce the ciphertext. As stated in the article DES is dead. Long live…Well, um, What, “First it encrypts, then it decrypts and finally it encrypts again” (Moskowitz, 1999). Three DES is now used because it is very resistant to cryptanalysis, serving as an alternative to add security against the potential vulnerability of DES to brute-force attack. Triple DES has been adopted for use in the key management standards ANSI X 9.17 and ISO 8732, along with a number of Internet-based applications, such as PGP and S/MIME (AES, Ciphers, and Confidentiality, 2005). The picture below shows the triple encryption process, as well as show the middle portion of 3DES as a decryption rather than an encryption making it more secure.

A nonce and key distribution center (KDC) shares a secret key or “master” key between each party on a network. The KDC is responsible for generating nonce and keys to be used for a short time over a connection between two parties, known as session keys, and for distributing those keys using the master keys to protect the distribution. The following steps occur:

1. A issues request to the KDC for a session key with B. The message includes the identity of A and B, as well as a unique identifier for the transaction, a nonce, which may include a random number or a counter.

2. The KDC replies with a message encrypted using Ka. Thus, only A can read the message and knows the message originated at the KDC. The message includes:

• The one-time session key, Ks, to be used for the session.
• The original request message, including the nonce, to enable A to match this response with the appropriate request.

In addition, the message includes two items intended for B:

• The one-time session key, Ks.
• An identifier of A, IDA.

These are encrypted with the master key that the KDC shares with B. They are sent to B to establish connection and prove A’s identity.

3. A stores the session key for use in the upcoming session and forwards to B the information that originated at the KDC for B. This information is protected from eavesdropping, because it is encrypted by the master key, Kb. B knows the session key, A’s identity, and that the information originated at the KDC.

4. B then sends a nonce, N2, to A, using a newly minted session key for encryption.

5. Using the session key, A responds with f(N2), where f is a function that performs some transformation on N2 (e.g., adding one) (Stallings, 2003 pgs 214-15).

In conclusion, the above explained how DES works, why 3DES is now used, why the middle portion of 3DES is a decryption rather than an encryption, and explain a nonce and a key distribution center.

The Role of a Network Consultancy

Whether you are setting up a new company or you are just getting ready for the next step in your business’s progression, you will find that one resource that you need to think about is a network consultancy. A network consultancy is essentially a business that gives you the most effective and advantageous network set up for your business and then after the network is set up, it will maintain it for you. The truth of the matter is that there really is an art to setting up a computer network and if you are in a place where this resource is necessary, you can get a lot of important work taken care of in one fell swoop.

The first point that you should realize when it comes to computer consultancy is that it provides you with a great deal of experience at your disposal. Computer consultancies have a great deal of stock set in how much experience they have in setting up a network that is efficient, effective and gives you the resources that you need and this is something that can take years of work to figure out. Networking may seem rather simple at first, but the truth of the matter is that there are many different resources that need to come into play at once. There are enough factors that are competing for resources that having a computer consultancy on hand is quite advantageous.

Another point that you will discover is that a computer consultancy firm can provide a great deal of relief when it comes to helping out your IT department. Your IT department has a lot going on and if you are just getting a computer network setup, you will find that the IT staffs is already going to be under a number of different stressors. Make sure that you consider what duties your IT department is already shouldering and whether adding computer networking to the mix is going to be something that they welcome. In many cases, you will find that your IT department may not even be set up for network installation and maintenance. This is not something that you want to necessarily integrate into your own staff, so consider how a network consultancy can help you.

Remember that at the end of the day, your computer networking is something that should be rock solid. In this day and age, your business can effectively grind to a halt if your computer networking goes down and this is not something that you want networking amateurs working on. With a good network consultancy firm working on your behalf, you will find that you are in a great place to move forward and to get your work taken care of. You will get the benefit of working with professionals who have a lot of experience behind them.

Networking is something quite complex and the truth is that it is growing more complex by the day. Take some time to consider the good that a networking consultancy firm can do for you and really get the most out of your business contacts.

Life is Unpredictable, Your Data Shouldn’t Be!

With the arrival of various internet based applications which allow people to express themselves, the web has definitely become democratic. But using the same for carrying out personal or malicious activities, and that too using your office computer can land you in deep trouble.

A senior executive at a marketing firm was accused by his boss of passing on vital company data to a competing firm, he denied it. “But we have the proof”, his boss told him and showed it to him, as clear as daylight. The executive resigned immediately. It’s a fact of life in the 21st century workplace; the boss may well be watching you, especially if you use a office computer. Improper computer use can also spell legal trouble. Downloading pirated music or movies onto a work computer can prompt a copyright-infringement suit. Viewing pornography or sending sexually suggestive emails can lead to sexual harassment claims. Thus, an employer can use special software to monitor everything – it’s as if a camera is watching your computer.

Companies are using two types of spying software: network-based programs that monitor all traffic passing through a system, and programs that sit directly on an employee’s desktop. What can such software do? They can track and block the websites a user tries to visit and log his or her every keystroke. The boss can see screen shots of what the employees do on Yahoo! He can see what they’re typing, whether it’s resumes or business-related stuff. Such program even keeps track of songs that employees download to their iPod. In the American and European countries, one in four companies reports firing someone for improper email use. Such software works without being identified, even by an anti-virus program.

There are plenty of valid reasons for companies to monitor their worker’s computer use.

1. Productivity: A recent survey found that employees on average wasted at least two hours a day-much of it online-doing things other than work.

2. Security: Porn, gambling and gaming sites, for example, can harbour viruses and other malicious programs that load onto a computer secretly and allow outsiders to damage a network or make off with sensitive information.

3. Companies also have competitive reasons to keep tabs on workers.

4. Employee attrition: With young employees who may have quickly changing loyalties, more and more companies see the need to spy.

5. Reputation Management: Companies want to be sure that there employee’s defamatory work does not harm the company’s global reputation.

Implementing all these policies may be beneficial for the companies, but the employees always feel pressurised. They feel paralysed, if their every activity from composing the weekly report to emails is tracked. And who hasn’t opened his email to find a message from a friend passing along a goofy YouTube clip or an off-colour joke. If it does get a laugh, it’s probably passed along to a few more people. And this can seriously land the employee who first circulated such content within the company.

It seems that technology will continue to creep unabashedly into the workplace. So, if you blog, forward naughty email, flirt, chat or search for a new job, just remember that it’s safest to use your own computer for any of that in the comfort of your home.

How to Synchronise Your Windows PC to a Time Server

Do you regularly need to correct the time on your PC? The answer is probably “Yes!”. This is because computers have very poor time-keeping hardware. Often, the system clock in a regular PC can drift by minutes each day. However, help is at hand. It is very easy to synchronise the time on your Microsoft Windows computer with one of the most accurate clocks in the world. This article describes how to configure your Windows system to synchronise it’s internal system time with an Internet based ‘atomic time’ reference.

PC’s utilise an internal hardware real-time clock to maintain time. Generally, this hardware clock circuit utilises very low-cost components. This results in poor time-keeping performance. It is not unusual for a computer to loose minutes each day. There are hardware solutions available, which can improve timekeeping, such as more precision crystal oscillators. However, modifying PC’s at board level is not an option for most users. Additionally, accurate time-keeping hardware can be prohibitively expensive. Ideally, a software solution to maintain accurate time is required. This is where the Network Time Protocol (NTP) comes in.

NTP is one of the oldest Internet protocols still in regular use today. Dr David Mills of the University of Dellaware invented it over 25 years ago. He recognised the need to synchronise time critical processes across the Internet. The Network Time Protocol allows client computers to synchronise to an accurate time reference over the Internet. NTP uses the UDP (User Datagram Protocol) over IP (Internet Protocol) to request time from an accurate time reference. It then waits for and accepts a response from the server before updating it’s internal system time with the supplied reference time.

There are many NTP Servers residing on the Internet. Government or educational institutions generally maintain them. A NTP server obtains highly accurate time from an external time reference such as GPS or Radio and maintains this time internally. It then distributes the precise time to network time clients.

The latest Microsoft Windows operating systems, such as XP and Vista, incorporate a SNTP (Simple Network Time Protocol) client. This client can easily be used to synchronise to an Internet or locally based NTP server. The client is configured from the time and date properties applet in the control panel, or by double clicking on the time in the system tray. One of the time properties tabs is labelled ‘Internet time’. On this tab is a field called “Server” which accepts either the IP address or domain name of a NTP time server. Click the “Update Now” button and Windows will attempt to synchronise with the selected time reference. Ensure that the “Automatically Synchronise with an Internet Time Source” option is ticked and Windows will periodically update time from the reference automatically, thus keeping your system clock accurate.

If synchronisation fails then ensure that the supplied IP address or domain name of the NTP server is correct. Alternatively, it may be your firewall that is preventing communication with the time server. NTP operates on UDP port 123, so you must ensure that this port is left open on your firewall. The Windows firewall can be accessed from the Control Panel. To open NTP port 123, open the Windows Security Centre and select ‘Manage Security Settings for Windows Firewall’. From the Windows Firewall applet select the ‘Exceptions’ tab. Click ‘Add Port’ to add an exception to the firewall. Enter a name for the exception, such as ‘NTP port’, and port number ‘123’ and check UDP. Click OK to accept the settings. If you have a separate combined firewall and ADSL router, you may need to refer to your manufacturers documentation to find out how to open a port on the firewall.

To conclude, most computers keep extremely poor time. For many applications that rely on accurate time stamps, this can be entirely unacceptable. However, by utilising the Network Time Protocol, everyone can ensure that their computers system time is kept in sync with the most accurate clock in the world!

External Hard Drive With RAID – My Book Mirror Edition

Western Digital My Book Mirror Editions are a great new form of data storage and backup. Western Digital is known for high quality external storage drives, but they have now added an extra layer of security with the ability to set RAID 1 or 0 on the Mirror Editions. Whether you need external storage for business or personal reasons, these drives are worth looking into.

The My Book Mirror Editions currently are available in two sizes – 1-terabyte and 2-terabyte. As with other My Book drives, these do not come at a small MSRP. MSRP on these units are $289 – $549 dependent on the size you get. Keep in mind, these are suggested retail prices; the units can be found for much less.

The My Book Mirror Edition measures 6.54-inches x 6.06-inches x 3.87-inches and weighs around 5 pounds. This, in concatenation with its polished black exterior and book shape, makes the unit presentable in any atmosphere. Additionally, there is a blue LED light, on the front face of the box, which lets users know the status of the My Book, with a simple glance.

Users have the choice between either RAID 1 or RAID 0 on the My Book Mirror Edition. Using RAID 1 reduces the overall storage size to half, but provides you with a duplicate copy of your data on the second drive. RAID 0 provides you with a bit less security – no replica of data – but gives you more overall storage space. The drives are somewhat customizable to your needs.

The unit has a Drive Manager, which enables users to view the status, temperature, and capacity of the unit. Users can also change the configuration through Device Manager. You can change from RAID 1 to RAID 0 and vice versa. (For consumers who do not understand what this will do, your data will be wiped if you reconfigure your unit to a different RAID setting.)

Western Digital implemented an application called WD MioNet, which allows users to access their drives via the internet. You can now access your data regardless of where you are at. Additional applications and software are available, some of which are WD Anywhere Backup, a 30-day trial of Memeo Autosync, Google, Desktop Search, and Picasa.

Installing additional software and transferring files is very user-friendly. The overall user-interface, and ease of navigation and use, enables users of any skill level to operate the My Book Mirror Edition nearly effortlessly.

If one of the hard drives, in the unit, happens to fail, users can easily replace. Each hard drive is simple to remove for this purpose. The unit only uses USB connectivity; no there is no way to connect via FireWire or eSATA.

If you are looking for an external drive for data backups, and would like a little bit of security with it, the Western Digital My Book Mirror Edition is the right move. With a little bit of bargain hunting you can add this unit to any network with a small dent in your pocket book.

Choosing a Computer Network Training Provider

When you are in a place where you are looking at the options that you need to get your workplace online, you will find that you are looking at something that can be greatly informed by your choice of network training provider. The truth of the matter is that no matter what industry you work in and what you are doing to make sure that you can get the results that you need, you are going to find that you are in a place where you need to make sure that you and your staff have a thorough understanding of the technologies and the networking that you are using. You can have the best system around and it will do you very little good unless you know how to use it! When you are looking to make sure that you are getting the most out of your network training, make sure that you consider a few points about your network training provider.

The first and most basic thing that your training provider should be able to accomplish is that they need to make sure that they can convey simply and clearly how the technology works to your staff. In the first place, think about how adept your staff is. Have they recently just come from one good networking system and now they are going to another, or are they in a place where this is all brand new to them? In either case, the training needs to be tailored to their needs and their comfort, so make sure that you can find a trainer who will do that.
Another point that you need to make sure of when you are looking towards hiring a good computer network training provider is that you need to think about how intimately they are familiar with the system that you are getting installed.

– What kind of experience do they have, and what can you do to make sure that you are in a good place where they get the information that they need to get across?
– In what ways are they preferable to an in house system and what do they offer when you are looking to get a certain amount of people competent on the material at hand?

You will find that the more information that you can get when you are classifying their work, the better off you are.

When you want to make sure that you are getting the best trained network engineers out there, you will find that you are in a place where training is crucial. Make sure that you invest in a training provider who will give your engineers the training that they need to thrive. Take some time and make sure that the people that you are looking to work with will give you the best results when it comes to getting your engineers the real life, hands on experience that they need.

Take some time to consider what you need out of your computer network training provider and make sure that you get it. Finding a trainer who suits you and who can help you achieve your goals will pay off in the long run.

USB Flash Drive Operating Systems

Did you know that you could get an entire operating system on a flash USB drive? Most firmware in modern PCs allows booting from these drives. That means that a bootable flash drive could allow you to launch an operating system, this is commonly called Live USB and applies mostly to Linux operating systems. However, there is a MS Windows version available and some versions of BSD are also available on flash USBs.

Live USBs are good special purpose or brief tasks like doing an operating system install or disk cloning operation across a network, loading a minimal kernel for embedded operations and maintenance tasks.

A properly configured Windows USB flash drive will allow you to install a version of Windows XP on a drive, with extra software if there’s space. To do this, a special utility is required, as well as a fairly large drive. You will end up with a portable, compact emergency version of your operating system.

Live USBs are more commonly used by Linux operating systems, and are closely related to the now-common live CDs. Like CDs, USBs can be used to help test a distribution, recover data and many other tasks. Live USBs have many of the same limitations and benefits of a live CD. It is, however, easier for a live USB’s data to be changed, since CDs are usually permanently written. That makes it easier to use a live USB as personal storage, allowing a user to carry their preferred applications, operating system and configuration. Sharing a single system between multiple users is much easier in this case.

Live USBs can also provide extra privacy, since the USB device is carried by the user and storage in a safe location is easy. However, the small size of these devices also means that they are easily lost and stolen; making backups and encryption more important for USB flash drive operating systems than normal desktop operating systems.

Since USB drives have no moving parts, they are able to have a faster seek time than optical media and hard drives, this means small programs start faster from USB flash drives than from a live CD or hard disk. However, the low data transfer speeds of some USB devices can make booting from them very slow. In addition, older computers may not have a BIOS that supports booting from USB devices. Booting an operating system from a USB drive may slightly reduce the life of the flash drive.

Carrying your own personal operating system in your pocket can be extremely useful for travellers or people using shared computers. Some sites offer tutorials on simplified flash drive installation for many different distributions of Linux (which is the most popular OS for this purpose). These tutorials mean it is much easier to install, boot and run your preferred distribution, with all your settings and files, from a very small drive. Just be sure you have a large enough drive and that you are using it in a computer capable of booting from the USB port.

Note: USB 2.0 capability greatly speeds things up, as well.

What is a WAN Service and How Can it Help?

A WAN, or Wide Area Network is a computer network that covers a large area, such as those whose communications need cross metropolitan, regional or national boundaries. A WAN is used to connect local area networks, or LANs and other networks together; the linking of these computers allows users and computers in one area to communicate with users and computers in another location.

Most WANs are designed for a single organisation and are privately used. Those that are built by ISP, Internet Service Providers, provide connections from various organisation LANs, or local area networks, to connect to the Internet, in this way, communications can be delivered over national boundaries.

These types of communications include;

  • Instant messages
  • Emails
  • Real time auctions
  • Online ordering placing

This in turn can reduce costs for companies by eliminating the need for travel and expensive long distance phone calls.

The benefits of using a WAN are that you can connect computers that are located over a vast area together. A network that can exchange data between sights is efficient and effective. The WAN enables computers to communicate with each other, some at different times and others at the same time. Not only can data be shared, but video as well, WANs are used for video conferencing and web casting. When communication is being shared between computers, each operator can access the same information at the same time.

When using a WAN, major corporations can reduce the branch office in house costs by enabling a centralised data centre to handle backup and storage resources. The use of a WAN also improves employee productivity by increasing and accelerating work applications as well as reducing replication across the WAN.

The use of private WANs have significant benefits also; the network is safe, secure and as it states, private. This type of network can reduce support and maintenance costs. There is an increased speed of the data that can be transmitted between sites because no other users are on the network. There is the ability to quickly access data that might be stored at different locations. This is also a great way for a company to provide training to their employees without the expense of airline tickets, hotels and providing meals for them.

As you can see, the benefits of having a WAN are vast. Whether you are using a private network to utilise quickness and efficiency between your satellite offices, or whether you are using a public WAN such as the Internet to purchase an item, communication between geographic areas is an important role in our society. Many people have used the Internet to gain knowledge by attending on-line college classes, or just have some fun playing an on-line interactive game; all of these activities were accessed using a WAN. The use of WANs offers opportunities never before possible for businesses as well as the everyday consumer.
