Vulnerability assessment done for an organization’s network gives a report of the security status of the network. While setting up the WiFi connection in the home or in an office PC most people ignore the WiFi Security. But if you don’t secure the network path with some tools probably your neighbors will be able to browse the web using your Wi-Fi connection. If the security levels are not adequate there are hackers who will intrude into your computer system with the intention of destroying the data.

An organization might have a network which is very secured. Yet as an exercise to vulnerability assessment attacks from internal or external network are simulated and these are mapped to certain parameters. Once the security is assessed then a report to detail the security breaches is made. Several solutions and fixes and patches to these vulnerabilities in the network are also suggested. The research and development team normally discover these security vulnerabilities in the network in the company.

This vulnerability assessment of networks is required in companies due to more threats with greater severity and frequency. The assessment helps to strengthen the security of the current network against worms and virus from internal and external sources. There is need to have security solutions that are beyond core level technology to cover the entire network. The needs of the software customers is changing, the access rights, and the permissions required for software are growing, and hence assessing the network for vulnerability is extremely essential. Security compliance is a big matter of concern in the software sections of a company as much as the upgradation of the software.

It is always a rushed job to set up a WiFi connection for a home PC and one tends to ignore WiFi Security. It can take time to install the security features of the WiFi networking product and so you normally end up with a not so secured network.

To connect to WiFi networks you need an access point called a router. To set up a router normally you enter the network address and account information. Now the account information for the routers normally has username and password which can be easily decoded by the hackers. You should change these to something complex and unique to yourself to enhance WiFi Security and should employ the highest measure to save its integrity.

It is advisable to turn on the WPA or WEP encryption with lowest denominator for your WiFi messages over the web to enhance your WiFi Security. Thus the information will travel in a scrambled manner over the World Wide Web.

The default SSID for the access points and routers should also be changed to increase WiFi Security. Connecting to your neighbors open WiFi is not advisable. You might think that a free wireless hotspot is there for you to connect but then you are exposing your computer and hence this is also violation of WiFi Security.

Special software can be installed to get a real time picture of the entire networks security. A picture of conformance to IT security standards and integrity are also obtained with the help of this vulnerability assessment software. To enhance WiFi Security it is required to assign static IP addresses to devices. This can prevent internet hackers from knowing your private IP address range for your company and accessing your computer using the World Wide Web.

The emerging standard 802.16 defines a network of wireless broadband at speeds capable of delivering triple play access to voice, data, and multimedia internet services. As a disruptive technology, WiMAX stands to compete with cable companies, the Telcos, and the 3G cellular networks. Thanks to the IEEE standards committee and the WiMAX Forum, the fledgling technology that got serious in 2004 is now being deployed in regions around the world.

Companies like Intel with their World Ahead program have formed partnerships for WiMAX deployments in Asia, Africa, and Europe, in an all out effort to bridge the digital divide. The cost effectiveness and ease of a WiMAX deployment is significant compared to implementing a wireline infrastructure, making the technology a natural choice for underdeveloped townships and hard to reach localities.

As it stands today, most of the deployments are of Fixed WiMAX, offering VoIP and data transfers through line of site and non line of site antennae, with a fiber optic, satellite, or WiMAX backhaul, i.e. Internet connection.

In 2008, the 802.16e standard known as Mobile WiMAX is expected to come of age. Mobile WiMAX will provide for faster handoffs and will be able to compete with the cellular 3G networks. As a technology based on open standards, WiMAX is considered to be future proof, in that upgrades to emerging standards should be easily accomplished.

In the United States, FCC Chairman Kevin Martin recently stated that broadband access is a top priority for the FCC, and that the upcoming auction of frequencies in the 700MHz spectrum provides an opportunity for wireless internet access to become a third choice for consumers.

Today, most of the WiMAX 2.5 GHz spectrum is owned by Sprint Nextel and Clearwire Communications. Martin says the FCC is auctioning off some of the spectrum in smaller blocks to give smaller companies a chance to compete, and to bolster overall competition in the industry.

The 700 MHz ban would be especially well suited for Mobile WiMAX, delivering large amounts of data at low power. The spectrum is being made available because of the analog to digital television transition. Another advantage of this range is its ability to penetrate deep into dense structures, potentially making the dropped call phenomenon so typical of todays cell phones a thing of the past.

WiMAX is a robust technology, capable of delivering large amounts of data at high speeds over an area of daisy chained base stations. But what will be the Killer App in a WiMAX network? The one application that gains widespread acceptance, makes the most money, and fosters development and competition.

Some think the killer app could be TV over WiMAX. The company MobiTV is working with the WiMAX Forum to do just that. They already bring over 50 channels to your phone or PC, and also offer TV over WiFi.

For municipalities and those concerned with homeland security, surveillance could be the ultimate app. Cities could easily and cheaply cover all departments with a single T1 backhaul, police would have instant access to data, mug shots etc, and wireless cameras could be deployed to monitor security sensitive areas. Crime could potentially cease to exist with big brother on constant wireless alert!

Probably the biggest money maker for a WiMAX network would be Internet telephony. VoIP has already been deployed on WiMAX networks throughout the world, and the very concept of cheap phone calls globally has led consumers to VoIP pure plays like Vonage or Packet8, and the cable companies are also getting into the act.

For the underdeveloped populations most effected by the digital divide, cheap, reliable phone service could open up a whole brave new world.

Alice Brooks asked:


At an organization the monthly sales were going down for a few months at a stretch. With just a little investigation the administrator found out that the employees of the company were more interested in “orkuting” and “twittering” in these social websites. Many were even viewing pornographic material while some were interested in shopping with eBay. To stop these indiscipline web content filters were installed, which prohibited viewing of content of certain websites. That’s what made the sales to reach peak values again. One can think of installing wifi security measure to make the system full proof.

Wi-Fi or wireless networking is being widely used as it is inexpensive and has an easy set up. For these reasons it is used in both homes and offices. If we think from the corporate level, data is extremely important and confidential. Is it safe to send it through the wireless medium? People who are using it at their homes are generally not much security conscious but IT is definitely concerned. Hence, Wi-Fi security maintenance is extremely important in order to protect it from being mishandled.

Web content filter finds a lot of utility at homes with little children. These days’ school students have become internet savvy, which has become a source of concern for the parents. While browsing websites, there is a high chance of them viewing adult content. To avoid such instances parents are now finding solace by installing a web content filter in their computers. These filter softwares are becoming more parent-friendly by the day. Parents have the facility of filtering certain categories like ‘sex’ or ‘drugs’.

But most of these web content filter software utilize Artificial Intelligence owing to which over filtration is never done. A child might be interested to know the recipe of ‘fried chicken breasts’ but due to over-blocking of adult sites he/she would not be allowed to view it. But these software’s perform a run-time content filtration, which goes through the content properly before blocking it. Parents can be rest assured that their children will never be able to by-pass the web content filter with no knowledge about the password.

Wireless networks can suffer a variety of attacks due to which Wi-Fi security is a must. Here, are some of the ways in which you can maintain security across your wireless network.

- A WIPS or Wireless Intrusion Prevention System is a great way to counter wireless attacks.

- Mac ID filtration is a method of Wi-Fi security where the administrator allows the entry of computers in its network, which contains some specific Mac IDs only.

- Smart cards, software tokens and USB token are helpful in maintaining tight Wi-Fi security. These cards and tokens can be both hardware and software, which when used with any server software will show brilliant results. A strong algorithm is formed with user entered PIN number and the card/ token internal ID code that will from time to time create a new encryption code. The server will always be in sync with the card/token.

- WPA (Wi-Fi Protected Access) and WEP (Wired Equivalent Privacy) are some of the other Wi-Fi security measures.

Install web content filter and wifi security appliances to make your internet viewing safe and enjoyable.

Andrew Peterson asked:


Internet has certainly provided a comfortable platform to the people for accessing almost everything. But for availing these services, one need to have Internet connection. Earlier there were dial-up connections for the connectivity purpose, but they used to bother a lot, due to the slow downloading speed and hindrance to the phone line. Then the need of something fast and hassle free, gave birth to broadband connections. There are two broad categories Home Broadband and Mobile Broadband, and both are quite fast and better. The second one could be kept under the category of Wireless broadband .

Different usage of different users has created these categories, and they are modified accordingly. The wireless mobile broadband is not as much faster as the home broadband, but still it has its own advantages. One of the major benefit of this connection is the mobility provided to the users. It helps to move freely from one place to another, without getting disconnected, or dragging bothering wires.

Under the wireless Internet connections, we have mobile broadband and Wi-Fi. Although both are capable of providing mobility, both have different functionality and limitations. The technologies used for connectivity, in the mobile broadband are – 3G, HSDPA and EDGE. A USB like device is used here, which has a SIM card of the connection provider. Its quite portable and easy to use, by just plugging it into any system, a user can start surfing at anytime & anywhere.

On the other hand, the Wi-Fi connection has a wireless adapter which translates data into radio signals and transmits the signals over an antenna. And this transmitting antenna is generally connected to a DSL or a LAN. In the network, there is a wireless router, which receives the signals and decodes them. Ethernet connection is used by the routers to transmit the information over the Internet. It works in different ranges, around 120 feet indoors and 300 feet outdoors. The spots or plots, from where these devices operate, are known as Wi-Fi hotspots. With the increase in the distance between the user and the signal, the speed of the connection decreases.

There are many wireless broadband providers in UK, and few leading amongst them are – O2, Virgin Media, 3, Vodafone, Plusnet and Talk Talk. The fierce competition between these connection suppliers has forced them to provide various deals and offers. These have certainly benefited people in a great manner. Although there are many attractive promotions like free gifts, discounts, free LCD TV, free playstation etc., but there is one deal which is quite outstanding. A free laptop with wireless mobile broadband ii a wonderful deal, which increases the mobility and comfort of a user.

Numerous wireless broadband provider has definitely confused the mind of people, and to select the best one amongst them is even more difficult. In a physical market, it requires a lot of efforts with time and money. But as a solution, there are many online shopping portals, which has all the details of these suppliers. And few dedicated online comparison portals allow to compare their packages and prices.

Wireless broadband connections, in the form of mobile broadband, are the best options for the people who travel a lot, and needs to stay connected all the time. And the Wi-Fi option allows to move freely within a limited range. Both are good in terms of mobility, and to avoid bothering wires.

Jim Brown asked:


Wi-Fi (Wireless Fidelity) is a great new internet solution that is available pretty much anywhere there is a broadband connection that is connected to a Wi-Fi modem.  Wi-Fi basically allows multiple computers to use the available broadband connection without wires or cables.  Gone are the days of having annoying data cables and the need to be chained to a desk to get super fast internet.    But if your business is looking into Wi-Fi, what are things you need to be aware of when considering utilising this new technology?

Securing Your Wi-Fi

Security is absolutely essential with Wi-Fi connections.  Because it can be connected to by any computer or device in the local vicinity (even ones you don’t want using the connection), it’s important to ensure your modem allows the functionality of a password when a user tries to connect.  The key is to not make it easy to guess, but not so difficult that you won’t remember it.  Some modems will only allow for numerical code, while others will let you choose an alphabetic password.  Depending on the nature of your business will ultimately decide who you allow your Wi-Fi access to.  If you are an office based business, Wi-Fi gives you the luxury of letting staff “hot seat” without the need for dedicated desks.  Anywhere there’s a spare seat and table, you’ve got yourself a work space!

On the other hand, if your business is in the service industry like a cafe, hotel, restaurant or even a hairdressing salon it’s a great idea to make Wi-Fi available to your patrons – this service is often referred to as a Wi-Fi hotspot.  As Wi-Fi can also be used through mobile phones, many customers will often use the service to surf the web via their phone while sipping on a coffee or getting a haircut.  But unlike normal Wi-Fi connections, to become a wireless hotspot there is specialist software that you’ll need to purchase to allow users to have easy access and to also manage your data usage.   

Whether it’s providing Wi-Fi for your office so that staff can move about freely while working, or a hotspot that lets your patrons relax and surf the web, Wi-Fi is the next wave of technology that is catching on fast.  Just remember, set a non-descript password so that unwanted devices can’t utilise your connection and use up all of your available data!

Wireless internet or Wi-Fi is one of the latest developments in providing people with Internet access whenever they need it – even while traveling. This is a convenient way to stay connected with family members or business clients anytime of the day.

With the fast evolution and advancement of the Internet, millions of people all over the world make use of the Internet in their daily life. The internet offers a lot of useful information such as weather forecast, entertainment, research, music, news, online shopping, and many more. The Web also provides a more convenient way for people to communicate with others even in far away countries.

Businesses are also dependent on the Internet in dealing with their clients whether local or abroad. They too are kept posted with the trends as well as stock updates though the Net. They also use corporate e-mails in nearly all of their correspondence. Customer services and technical support of many companies also rely on the power of internet. Indeed, the Internet had become a necessity for ordinary people as well as business people.

Because of enormous growth of dependency on the Internet, people want to have internet connection even when on the go. This is now possible through the development of wireless Internet. Wireless Internet is popularly known as Wi-Fi, which is the trade name of this kind of wireless technology. A wireless Internet access is commonly called as hot spot in which a LAN or local area network transmits radio waves as opposed to a wired network.

Internet connection is broadcast with the use of a central hub connected to a computer system that functions as the server. The server broadcasts the signal to clients which have Wi-Fi capable devices such as desktop computers, PDAs, laptops, mobile phones, game consoles, and many more electronic gadgets. The wireless internet covers diverse IEEE 802.11 advanced technologies such as 802.11n, 802.11b, 802.11g, and 802.11a.

A home network can be set with wireless Internet, as well. This is done through the utilization of a router which performs as an access point. The router broadcasts Internet connectivity to Wi-Fi enabled devices within its area of reach. With this set of connections, anyone from the family can make use of their laptops or desktops and can gain access to the Internet.

What’s more, wireless Internet through home network can also be accessed by neighbors without your knowledge. To resolve this issue, a password security can be configured so that only authorized devices can have access to the network. With the growing risk of security issues, the security protocols for Wi-Fi log on have been made available with the employment of Wi-Fi Protected Access (WPA) and the Wi-Fi Protected Access 2 (WPA2).

Wireless internet through its public hot spot is being offered for free to its customers by many business establishments. These establishments include internet cafes, food chains, coffee shops, hotels, and restaurants. Some airports also provide the same service for travelers’ convenience. These features are becoming very prevalent in many places and countries. There are also a number of cities which provide wireless Internet access to their residences and visitors. Since the hot spot can cover only a certain area, you have to be within the range of the hub in order to log on to the Web.

Significantly, a wireless Internet is of great advantage compared to wired network. Wired network usually consumes a lot of time in order to set up in a building or house. It also entails more expenses as it requires a lot of UTP cables to be wired for each of a client’s computers. In some instances, there is a need to route wires through thick wall or ceilings. Wireless LANs can be deployed easily and is less expensive. More clients can be added to the network without the necessity for extra materials.

Since 2008, many of the latest laptops and gadgets come with a built in wireless network device. There are also a lot of gadgets which can be applied for computers or laptops that do not have any wireless network device. Some of these devices are the USB Wi-Fi adapters, PCI wireless adapters, PCMCIA Wi-Fi cards and other similar devices. There are also wireless repeaters used to extend the range of signal of any existing wireless network. This device is ideal for locations having many physical barriers like thick walls and in cases where there is a need to share the Internet in two separate buildings.

Communication forms an important part of any business today. So, every business is now keeping itself totally equipped with the latest communication tools like the internet, in order to keep in touch with the clients and business associates and to keep abreast of the competition. The internet is used for a variety of purposes such as customer care and technical support by the business organizations.

One great utility of the internet that has now emerged as a great communication tool is the Voice over Internet Protocol or VoIP. Several businesses and even common people are switching over from using the regular telephone to using VoIP for business purposes as well as in homes.

One reason why this transformation is occurring is the cost factor. VoIP has enabled users to make calls to other people at very cheap rates and even for free. It also has a lot of additional features that are not usually available while using the regular telephone. VoIP uses the internet to make and receive calls. The system works by converting the analog audio signals to digital format which gets transmitted on the internet and reconverted at the other end to be heard by the receiver.

There are many features present while using VoIP that is not found with the conventional landline. These include features like answering machine, audio and video conferencing, caller ID, three-way calling, etc. The basic package offered by various VoIP service providers can be utilized free of cost. This goes to say that all you need to do is have a fast internet connection, subscribe with some provider and you are ready to make calls. The other basic infrastructure you need is an internet phone and a computer.

While some providers will themselves be able to provide the internet phone others provide software that enables the computer to be utilized like the telephone.

The advantages to the VoIP system do not end here. If the users at both the ends have subscription with the same service provider, the parties can make and receive calls for free wherever they are. Since the internet is being used for transmission of all the calls, even calls to regular telephones, cell phones, and phone services provided by different VoIP service provider are also quite economical.

If a person has Wi-Fi enabled in his/ her home, they can make use of wireless VoIP that necessitates a Wi-Fi phone. If the person has Wi-Fi connectivity in a broader area, the Wi-Fi phone can be used like a cell phone in the areas where the connectivity is available.

Wi-Fi phones are gaining popularity with people using VoIP for making calls. This is due to the freedom that these phones provide where the person will not need to be located in his / her home to make and receive calls through the VoIP mode. All they will need is to have an active Wi-Fi signal.

So, if you have Wi-Fi connectivity to the internet in the area where you live, you too can opt for a wireless VoIP system. Having such a system will not only enable you to make and receive calls without having to be stationed in one place, it will be cheaper than using your mobile phone for calling.

Wi-Fi is a great technological advance available and VoIP is effectively using this to its benefit to enable users of this system to make and receive calls very easily.

To utilize all features provided, it is best to confer with your other contacts to know which Wi-Fi VoIP service provider they are subscribing with. This will enable you to make and receive calls to your near and dear ones in addition to your business associates and clients totally free of cost. You can make maximum utilization of the services provided as most of your contacts have opted to use the service provider that you have also subscribed with.

Several additional features provided with VoIP system is available to the users free of cost but will cost extra if a regular landline phone is being used. So, if you too want to get these features for free, go in for VoIP.

You will be able to save a lot in your monthly bills if you frequently make overseas calls. VoIP will give you freedom from watching the time elapsed while making long distance calls as these calls through VoIP is quite cheap and you can talk to your hearts content.
