...Paper CNT4514 Wireless Vulnerabilities The world of wireless networks as we all know is one of the most rapidly growing areas in our world today. With the massive amount of data that is going on, “the cloud” the security of all of our data is questioned. As well with so many of our day to day tasks relying on our wireless capabilities it make you wonder how safe is it to rely so heavily on something. We have to ask the questions what are the key vulnerabilities of wireless networks and even just of networks in general. Different types of networks have different levels of safety and it is a good idea to know not only which are safe but the vulnerabilities of said networks to keep our information out of the wrong hands and keep our day to day life moving as smoothly as possible. Unlike wired LANs the wireless LAN users are not restricted to the physical area of a wired system. While this may feel beneficial to the user it is also very beneficial to sniffing and eavesdroppers who are listening to the radio waves that are broadcasted through the air. Intercepting these packets they can pick up messages that may contain sensitive information. Seeing how the range of a wireless LAN can extend beyond the building the eavesdroppers don’t even need to be inside the building. A simple thing you can do is open up your wireless adapter on your computer and see how many open wireless networks are around you. From my house I currently have 4 open wireless networks that I can connect...

...RECOMMENDATIONS FOR WIRELESS NETWORK SECURITY POLICY Introduction One of the newer technologies being increasingly used in today's business is that of wireless networks. While this technology has the advantages of providing greater user mobility and temporary access, it does have the disadvantage of an intrinsic lack of security. SECURITY THREATS There are a number of types of attack that wireless LANs are vulnerable to, based on different aspects of their operation and configuration. These include. i. Broadcast medium Wireless is a broadcast medium, where there is no way to control where the information is sent and who therefore has access to it. If an access point is set up and used in its default Configuration, then the user of such a system is vulnerable to attack, because anyone running sniffer software can see and capture everything that a user does across that network... ii. WEP Vulnerabilities. There were two problems with the original WEP encryption system. Firstly, the shared key system requires the use of the WEP key to verify a user attempting to connect to the wireless network. The second was the actual implementation of the encryption system itself. iii. Denial of Service This type of attack can be perpetrated by a jamming attack which can be either intentional attack which is one in which the attacker broadcasts a very high-power signal at the same frequency that the wireless network is operating on, causing interference to the network or unintentional...

...In this ever changing world, wireless communications has become a major platform for communications at work and at home. With popular mediums (Cell phones, PDA’s, Gameboys, Wii, Netbooks, iPods, etc…) like wireless devices, there are many advantages and disadvantages in operating wirelessly. No matter how you feel about the advantages or disadvantages of the devices, they need to be protected, along with setting up some form of security. On the website Howstufworksvideo (12) they show you the basics on how to setup home Network Security. You can go there can see how it is done. Just a few years ago, (25 Sep 07) there were some so-called experts saying that there was no need to secure your wireless system. In an article, David Ramel alleges that the importance of wireless security is overhyped, that it's now trivial to secure wireless nets and that IT pros have far more serious security concerns they should be addressing -- while home users have little to lose even in the remote chance someone tries to breach their network. (3) This person was obviously living in a sheltered environment because identity theft and credit card theft was out of control then. Now he is saying don’t worry about protecting your network and to just hold on to your wallet; basically. Either he was very innocent or totally clueless and is eating humble pie about now. Here are a few disadvantages. A limited spectrum, war driving, interfering signals can be generated by other devices in the...

...Wireless Network Security Wireless networks in personal homes are becoming more and more popular. With the ease of using no wires and the signal being broadcasted throughout the house, the new printers coming out that are network ready, and along with the new gaming systems like Playstation 3 and Xbox 360 all have wireless network settings. A wireless network is the most vulnerable network out if the precautions of taking time to set up the security properly. Everyone saves personal important information on their computer systems. When there is a wireless network with the settings not set right the computer system is fair game for any, who would like to look at information stored on the computer system. Viruses are not the only thing to protect against. Outsiders or even a neighbor can easily get into a computer’s information though a wireless network. Identity theft can even get implemented with wireless security, if you have a lot of personal information. Credit card information and bank account information can all be stolen from the system and then used for evil. Not only are personal homes affected, but businesses can be too. WarDriving is a big fad among the computer ‘hackers.’ WarDriving came from the movie “WarGames” staring Matthew Broderick. In the movie he did what was called “wardialing”. Wardialing is to keep dialing numbers that would access a computer system’s modem until you find a modem and gain access. WarDriving is where someone can drive around in a vehicle...

...Computer hardware is no longer a major barrier to wide use of wireless information systems. Wireless technology is evolving and becoming the preferred choice for connecting hardware and transferring information. Employing a wireless system allows corporations, like cruise ships, to provide a wireless service to its passengers without comprising information security. Without wireless technology this service would be impossible. To set up a basic wireless network, you will need a network card/adapter, a wireless router, and access points. The network card is the most important hardware component of wireless networking. The wireless router and access points are used to increase performance, accommodate more computers, and increase the network’s range. Network adapters are used to interface a computer to a network. They can be found as a traditional PCI card, PC Card adapter, USB adapter, media adapter, or an integrated wireless adapter chip. A wireless router allows multiple devices to access one internet connection. Through radio frequencies, data is transferred between devices connected to the network. Access points serve as the central receiver and transmitter of these radio frequencies. Other factors to consider when setting up a wireless network are compatibility, expenses, limitations due to distance and building structure, and Wi-Fi network security. Wireless network technology, also referred to as WLANs, uses an industry standard known as IEEE 802.11 that...

While increasing convenience, connectivity, and productivity, they also pose an unprecedented threat to network security guarding, which has literally taken to the airwaves. This paper will deal with vulnerabilities and risks regarding access points (APs) in a wireless network (WLAN) connecting to a wired local area network (LAN) in enterprises. Data for this paper will come from published academic papers, industry publications including white papers and surveys, and industry specialists. It will also include definitions of terms, policy and procedures that affect access points, and current practices regarding rogue APs. A case study will be presented for a fictional enterprise with multiple locations that has standard procedures, policies, and protocols in place, but recent events have questioned their ability to control access points with the discovery of rogue devices hidden in several office locations. Industry warnings about access points span the past thirteen years, and still new articles appear saying similar warnings, with only the solutions evolving with the technology. Suggested solutions will include security literacy regarding APs and their devices and their compliance; security audits to re-evaluate configurations of current...

...Wireless Communications Paper Wireless communication involves the transmission of data from one point to another without the need to run cabling in-between. Although it seems relatively new to the end user today, it has surprisingly been around for longer than you may think dating back to the late 1800’s. The first wireless technology discovered was the Radio Frequency (RF signal). Thomas Edison and Nikola Tesla were two inventors that played a huge role in developing the RF technology we still use today. By conducting many experiments using wireless technology they together came up with the RF signal that was first implemented in WWII by the US Military. It wasn’t until the 1970s’ that the first ‘wireless network’ was developed called ALOHAnet. This new wireless network was made to communicate from island to island is Hawaii. Using LAN technologies and a 400 MHz frequency band ALOHAnet was the predecessor of many wireless technologies to come. Today we have many wireless technologies that are used for many different types of services. If you’ve used Bluetooth technology then you’ve used a Personal Area Network (PAN). A PAN network is intended for short ranges and typically controlled and used by a single person. If you’ve connected to the internet at work, a coffee shop, work, or at school then you’ve connected to part of a Wide Area Network (WAN) configured into a Local Area Network (LAN). Most people know a typical WAN by the name of WIFI, even though that’s just a business...

...Wireless Wide Area Networks: Trends and Issues Wireless Wide Area Networks: Trends and Issues Mobile computing devices are getting smaller and more powerful, while the amount of information is growing astronomically. As the demand for connecting these devices to content-rich networks rises, WWAN technology seems like the perfect answer. But today's wireless WANs have some limitations. This white paper discusses those limitations and how NetMotion™ overcomes them. · Specialized equipment and custom applications were needed for deployment over these proprietary wireless systems. · Often the wireless infrastructures themselves were difficult to deploy. · Only a small percentage of the working population was mobile, so corporations considered wireless data deployment a significant investment with little return. Why the resurgence of interest in wireless data networking technologies now? In the late twentieth century, a few interesting social and technological developments took place. In the late 1990's, businesses began seeing the economic benefit of having employees who work away from their campuses. These remote (and sometimes nomadic) workers needed access to everyday corporate information to do their jobs. Providing workers with remote connectivity became a growing challenge for the information staff. Handheld and pocket-sized computers became powerful enough to be useful. The convergence of Internet networking technologies made IP the de facto standard. New standards such...
