Wireless Security : Wireless Network Essay

Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

Wireless attacks have becoming a more common security issue when it comes to networks. Attacks can get a lot of information that is being sent across a network and use to commit crimes in other networks. Every wireless network is vulnerable to attacks and it is the important that all the necessary security measures are taken so as to prevent the mess these attacks can cause. These attacks are normally carried out to target information that is being shared through the networks. It is therefore very important to know of such attacks so you will be able to identify the attack when it happens.

Wireless networks have become a major part in the operation of businesses and in people’s lives. Wireless networks can provide fast speed internet connections without having to use wired connections. Businesses are doing much better with wireless networks because they don’t have to pay the costs of installing wired networks and people can work easier because they do not have wires running all over the place. Now with wireless networks in place, businesses are able to connect to their other branches and buildings within their area as well.

The vulnerabilities of wireless networking may involve the attack of web browsers, on-line banking, DNS servers, and routers exchanging routing table updates, purchases, transactions or stolen personal data. The lack of security with a wireless system may result in denial of service, hijacking, fake impersonation, or eavesdropping for interception of messages through cyber-crimes. Each communicating user should select the language of cryptography, agree and share the symmetric key. The best security practices includes firewalls, intrusion detection systems, secured and updated applications, transport, configured properly working network, and link layers.

The market for wireless communications has experienced incredible growth over recent years and wireless LANs have rapidly become a very

Local Area Network or LAN for short is the term used for computer networks located at a single location such as a small business located at a singular location. They are generally used for businesses, organisations and the likes to transfer data amongst their systems as opposed to transferring data to outside of their location. A LAN typically will rely on wired connections due to the benefits of increased security and speed, but a network called a WLAN exists, which is a Wireless Local Area Network and this may prove useful for those who come to work using mobile devices such as laptops, phones, etc. WLANs are simply local area networks that consist solely of wireless connections using a wireless access point (WAP) as the central hub. However, LANs can be a mix of both wireless and wired.Typically in a LAN, systems connected to the network are able to share resources among each other, send data to servers and use peripherals such as printers, scanners &

While wireless is often considered Ethernet, it uses CSMA/CA (Carrier Sensing Media Access/Collision Avoidance). Wireless network security and signal interference has been a real concern for network administrators. Most of these concerns have been addressed, but the reputation of being a largely free and wide-open media still lingers.

Wireless connectivity is critical to most homes and corporations as the world advances in technology. The technology has grown to a capacity that allows for extreme growth in wireless infrastructure as well as a trend of bringing your own technology device. Many corporations experience a high volume of critically important information being transferred over it wireless network so security is essential. There are many differences between a home and corporate wireless installation and each has its differences in securing.

The sender must make the information clear and unambiguous. The receiver must make sure the information is

24) Electronic data are more susceptible to destruction, fraud, error, and misuse because information systems concentrate data in computer files that

Examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks.

Wireless networks are less secure when compared to wired networks. Wired networks such as Ethernet are physically connected, where as in wireless networks are connected through wireless radio waves without physical connection between them. As a result, a security breach is easier in wireless networks when compared to wired networks. In the current world, electronic gadgets like cell phones, ipads and laptops are interconnected with other devices. In wireless device, a network radio receiver is able to hear the conversations on a wireless channel as per its range. Therefore it is easier to breach the conversations that are occurring in wireless networks. The data that is transferred on the internet should be reliable and secure because it might contain personal data information like bank login details or insurance details etc.

Security should always be a concern whenever planning, designing, implementing, and maintaining a network infrastructure. This is especially true for wireless LANs, which present unique challenges to home users and IT administrators. Unlike traditional Ethernet LANs, 802.11 wireless LANs advertise their network names (SSID’s) into the air unencrypted. This makes it easy for a hacker to intercept by sniffing the Wireless LAN for SSID advertisements coming from the access point. Although it’s possible to disable SSID advertisements in the access point, someone very determined and with the right tools can still obtain this information.

Brigham Young University Hawaii Campus wants to implement a campus wide secure wireless network. In their existing system there are some network security flaws such as rouge access point (Easily accessible open network), anyone can access and capture important information of users. We have been hired by the BYU-HAWAII to design and install a wireless network solution for the university.
