Wireless Devices : The Wired Equivalent Protocol ( Wep ) Essay

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.

Zhu, J., & Ma, J. (2004). A new authentication scheme with anonymity for wireless environments. Co

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:

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

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.

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,

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

Under the IEEE 802 standard, each one system interface gadget (counting system cards in machines, versatile Wi-Fi-empowered gadgets, and in addition individual ports in scaffolds or switches) ought to have an all-around extraordinary 48 bit MAC address. Pieces of locations ought to be bought by an association to be allotted to the gadgets that association produces. On the other hand, in a few cases a gadget might not have an internationally extraordinary MAC address. A few purposes behind this include:

Abstract :-Smartphone usage has been continuously increasing in recent years. Moreover, smartphones are often used for privacy- sensitive tasks, becoming highly valuable targets for attackers. The most popular Smartphones, including iPhones and Android Phones are vulnerable to different types of attacks such as denial of convenience(DoC).To address this attack, we propose implementing a novel Internet-access validation protocol that uses the cellular network to send a secret key phrase to an Internet validation server. Then, it attempts to retrieve this secret key phrase via the newly established Wi-Fi channel to validate the Wi-Fi access point

This report deals with the Security of Wireless Sensor Networks and how and why we need to secure them from any outsiders or attacks.

➢ Not always configured properly by user. Commonly uses WEP (Wired Equivalent Privacy) protocol for protection, though has been shown to be easily breakable. Newer wireless solutions are slowly providing support for the superior WPA (Wi-Fi Protected Access) protocol, though many systems still employ WEP.
