Limitations Of Wired Equivalent Privacy

Ever feel like you are being watched? How about having the feeling like some one is following you home from school? Well that is what it will be like if users do not have the privacy on the Internet they deserve. EPIC (Electronic Privacy Information Center), a advocacy group that has been fighting the Clinton Administration for tougher online consumer protection laws, and other privacy protection agencies have formed to protect the rights and privileges of the Internet user. With the U.S. Government, EPIC has had to step in and help small companies and Internet users with their own privacy problems, hackers getting into their systems and ruining the networks, and crackers stealing and decrypting private

Privacy: In a wireless network all the devices are able to hear data traffic within their ranges which can be a threat to the security of the link. IEEE 802.11 counters this problem by offering a privacy service option that raises the security level of the 802.11 network to that of a wired network.

During this presentation we learned of the network types that Whitewater uses and how they differ. For example they have three different networks which separate devices that are allowed to access the network. Their network gives each device a certificate that is good for 2 years. They also recently implemented a check in for devices accessing the network so that they can verify whether or not the user has an anti-virus installed.

Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:

To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from

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

Users that have a wireless LAN should add security to ensure only intended users have access. Some safeguards include use of WEP (Wired Equivalent Privacy) encryption, IPsec, WPA (WiFi Protected Access), with a firewall or DMZ. A DMZ (demilitarized zone) is a physical or logical sub-network that separates the LAN from other entrusted networks

WAP came in shortly behind WEP with secure networking communication in mind. It’s a later discovered that WEP doesn’t protect much at all and was then replaced with WPA/WPA2. WPA/WPA2 is the most widely used today. In fact, the only time WEP should be used is when there needs to be communication with old devices that don’t support encryption. WEP, or Wired Equivalent Privacy, is not hard encryption to crack. WAP, or Wireless Application Protocol, uses a smaller revision of HTML called Wireless Markup Language (WML), and is used is wireless devices. WPA/WPA2 is now known as the most secure communication over the internet today. WTLS, Wireless Transport Layer Security, provides authentication, encryption, and data integrity for wireless devices (Dulaney,

In Extensible Authentication Protocol, a random set of authentication mechanism is used such as using smart cards or certificates or using user’s credentials. Primarily the WLAN uses EAP for the purpose of passing messages during the authentication process.

WEP is an older security protocol for wireless networks that encrypts transmitted data. WEP uses a security code chosen during configuration called a WEP key, which uses a sequence of hexadecimal digits. WEP keys can be formed in different lengths depending on the type of WEP encryption being utilized. However it is generally not recommended to use WEP especially when we’re talking about networks that need more advanced security. The biggest disadvantage found with WEP is really it’s main weakness, a skilled hacker could actually crack the security key within a matter of minutes using special software.

Wi-Fi Protected Access 2, the follow on security method to WPA for wireless networks that provides stronger data protection and network access control. It provides enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. Based on the IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm and 802.1x-based authentication.

The concepts of wireless network security consist of commitment of cyber security and maintaining security based on the latest development and exploits against the network K.W. Ross, J. K. (2012). Wireless Network Security is based on the principles of cryptography, message integrity, authentication, securing e-mails, securing TCP connections: SSL, securing Network layer: IPsec, securing wirelsess: LANs, securing the operational security structure, such as the firewalls and the IDS K.W. Ross, J. K. (2012). This security

The café latte attack relies on a user’s laptop being connected to a Wired Equivalent Privacy (WEP) protected network and tricks the user into sending thousands of WEP-encrypted ARP (Address Resolution Protocol) requests. An ARP is a network protocol that maps together a network layer address and a data link layer hardware address. For example, an ARP is used to resolve IP addresses to their corresponding Ethernet address (Leyden, 2007). For a café latte attack to be successful, the cyber-criminal does not have to be in the same area as the user but can also be in a remote location to intercept the WEP key. A cyber-criminal can take advantage of the message modification flaws in the 802.1WEP architecture and the shared key authentication by flooding a network with encrypted Address Resolution Protocol (ARP) requests. A café latte attack functions by using a bit-flipping technique that modifies the Media Access Control (MAC) address and Internet Protocol address (IP address) of a user’s computer which is collected when gratuitous ARP requests are sent from the cyber-criminal. When the user responds to the gratuitous ARP requests, the cyber-criminal can quickly crack the WEP key from the user’s traffic. With a café latte attack, a cyber-criminal can obtain the WEP key in less

Although there are many threat of WLAN, you still can reduce those threats by applying some technology in your network. For example, you can use a Core Security Standard. It provides protection, which are confidentiality, authentication and message integrity, between the wireless access point and the wireless host. Furthermore, you also can use Wired equivalent privacy (WEP) security. In WEP, everyone shares the same access point, which requires the same key, and WEP’s key is not automated mechanism for changing. On the other hand, Wireless Protected Access (WPA) is also an option for you. WPA is developed by using the concept of Core security standard, so it could be used on older wireless access points and it is stronger than WEP. Finally, 802.11i is another solution for your concerns about the network security. 802.11i is considered as WAP2, and it uses extremely strong AES-CCMP encryption, which has 129-bits keys and a key management method for automatically changing keys. That’s all about the
