Unit 7 Wpa2

Wireless Local Area Networks (WLAN) have gained popularity compared to wired network due to its low cost and easy layouts. WLAN are used worldwide by users, corporations, and educational environments. Attackers can use any of several methods to get inside a computer with so many doors to protect and new hacking techniques constantly being developed, it’s difficult to keep safeguards

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.

Since the inception of IEEE 802.11i in 2004, users and IT administrators have been able to improve the security of their wireless networks by taking advantage of protocols like CCMP, an algorithm designed to provide both authentication and encryption. With CCMP, wireless networks can be secured with 128-bit AES encryption, provided by the Counter Mode component of CCMP. The CBC-MAC mode component provides the authentication mechanism.

When we discussing security from the point of view an end user, the essential WiMAX security concerns are protection and data safety, clients need conformation that nobody can snoop on them and the data that sent over the connection is not altered. This paramount as wireless signals might be easily sniffed by outsiders and if the data is not secured, information leaks could happen.

IEEE 802.11 commonly known as Wi-Fi is a set of media access control and physical layer specifications for implementing wireless local area network computer communication in various frequency bands such as 2, 3, 3.6, 5 and 60 GHz.

Most people believe that they are safe from hacking just because their network is secure. Recent evidence of WPA2 vulnerabilities shows that this couldn’t be further from the truth. WPA2 encryption is the industry standard for Wi-Fi security. While it promises impenetrable security, KRACK attacks show that it is as porous as an open network. You can only guarantee the security of your network through the use of a premium VPN. A VPN encrypts your data and transmits it through another encrypted network with servers around the world. Without a VPN, your network exposes your information, such as the IP address which can be used to track down your physical location. VPN encryption guarantees safety and privacy in such a way that no one can read your information and no one can pinpoint your actual location.

Temporal Key Integrity Protocol (TKIP) is an encryption protocol that is included in the IEEE 802.11i standard for wireless LAN networks. It helps provide more encryption security than Wired Equivalent Privacy (WEP). TKIP uses its algorithms to protect WEP’s security flaws and allows the users of older devices to upgrade without replacing any hardware. These algorithms are additional code at the beginning and end to capture and modify WEP. TKIP uses RC4 as its foundation but it also includes four more algorithms to increase strength: cryptographic message integrity check, initialization-vector sequencing mechanism, per-packet key-mixing function, and re-keying mechanism. Although, TKIP is used for upgrading security on devices equipped with WEP, it isn’t dependable or effective

Due to regularity and widespread vendor adoption, it is recommended to use technical option to establish a secured wireless broadband network. This will support delivery of online services and cloud computing applications with minimal complexity and associated client cost. With this intent, it is important that the network work seamlessly with standard 802.11n (Wi-Fi) clients (Comer, 2000).

Networking of computers has developed quite well since they were first introduced. Wireless networks are basically just the new trend of computer networks in the IT world. Of course with every new technology that is created, there are some pros and cons. This paper engages some of the key advantages and deficiencies of wireless networks security. It addresses various types of security levels being implemented by standard wireless networks, such as WEP, WPA and 802.11.This paper also discusses benefits of utilizing wireless networks, like cost effectiveness. Businesses have recently been found considering wireless installations simply because the lower total cost of ownership and maintenance. Other benefits will be brought to light, such as how wireless networks increase data accuracy and increases a user’s productivity. Wireless networks are starting to make their way into just about every venue possible, like schools, airports and hospitals. One of the main points that seem to always be addressed when discussing wireless networks is security and how people are concerned with the protection of their valuable information. In the conclusions, questions and opportunities for future WLAN research will be discussed.

Wireless technology has become the wave of the future. From cellular phones to wireless point of sale devices, wireless networks and technology is all around us. In order to jump on the wireless train, one must first understand the different standards. To properly and safely utilize wireless technology the user also must understand the various types of wireless security. Once grasping these technologies and standards, anyone can implement a wireless network in their home.

But still there were many flaws that intruders used to take advantage and used the flaws for their own advantage thus making WPA also vulnerable. WPA2 was introduced to overcome the flaws that WPA had in it. WPA2 uses AES (Advanced Encryption Standard) algorithm to provide security thus making it very difficult for intruders to break the security of this layer. As the algorithm encrypts secret and confidential data and it’s very difficult for the intruders to decrypt it. The issue with WPA2 security is that as it has complex encryption thus it requires a lot of processing power so the old systems which do not have the capability to process a lot of computation thus WPA2 is not suitable for the old deployed systems.

Abstract- The Advancement in various wireless Network ,Enables Mobile Subcriber to enjoy internet anytime anywhere ,but ensuring security and efficiency of this process is challenging, because different networks have different security policies and authentication protocols.. Wireless technologies such as the Wireless Local Area Network (WLAN), the Worldwide Interoperability for Microwave Access (WiMAX), and the Third-Generation (3G) mobile communications system complement each other to support a variety of services suited for the home, urban, and global environments. In Wireless roaming network, user privacy preservation has become an important and challenging issue in the wireless network, and has been widely studied by researchers.

If the Security Type reads “WPA2”, or something similar, then your Wi-Fi Network is SECURE.

In order to secure a wireless network from intruders several measures has to be taken care while implementing wireless network within the organization.Encryption algorithms are used to encrypt data over wireless network so that network cannot be easily read by the attackers. There are several authentication techniques that can be implemented to secure data over wireless networks such as: biometric technique, OTP method and Single Sign on techniques are used. Attackers use several methods to crack wireless passwords like brute forcing, so as to secure passwords strong passwords with special characters and keys has to be used making it difficult to crack.Wi-Fi Protected Access (WPA) or Wired Equivalent Privacy[4] (WEP) encryption is used by most of the
