Abstract This paper provides best-practice information to interested parties for designing and implementing wireless LAN (WLAN) security in networks utilizing elements of the Cisco SAFE Blueprint for networksecurity.AllSAFEwhitepapersare California, USA. • Unauthorized Association – an AP-to-AP association that can violate the security perimeter of the network. • With Wireless Networking, no cables or wires are needed to network your computers and share your Internet connection. To overcome this attack, proper authentication and access control mechanisms need to be put up in the wireless network. Download the network security seminar reports which explain different kinds of security mechanisms that can be applied according to the need and architecture of the network. All wireless computer systems face security threats that can compromise its systems and services. cell phones, and PDA's) used to access the Internet. Wireless LAN Security The various mechanisms and algorithms that are webbed together into current suite of wireless security protocols have serious flaws. Authorization can be thought of as a grid with each network resource along the x-axis and each user (or other entity) along the y-axis. These networks can be up and running quickly when there is no available wired Ethernet infrastructure. Wireless security presentation 1. 300 Chapter 11: Wireless LANs 1. The focus is on the security techniques available for Wireless Local Area Networks (WLAN) and for wireless devices (e.g. In Wired Communication, the medium is a physical path like Co-axial Cables, Twisted Pair Cables and Optical Fiber Links etc. The essence of an authentication system is discovering and confirming the identity of a person, an organization, a device, or more generally, of any software process on the network. which guides the signal to propagate from one point to other. Wireless local area networks (WLANs) based on the Wi-Fi (wireless fidelity) standards are one of today's fastest growing technologies in businesses, schools, and homes, for good reasons. It is a subset of network security that adds protection for a wireless computer network. Wireless Charging Of Mobile Phones Using Microwaves.

The attacker could also flood a receiving wireless station thereby forcing to use up its valuable battery power. the vulnerabilities of the Wired Equivalent Privacy (WEP), which is supported in the IEEE 802.11 wireless LAN standard. Unlike the wired network, the intruder does not need physical access in order to pose the following security threats: This involves attacks against the confidentiality of the data that is being transmitted across the network. The most common example of “something you know” is the traditional user ID and password combination. Wireless LAN Security 8, 9. In the wireless network, eavesdropping is the most significant threat because the attacker can intercept the transmission over the air from a distance away from the premise of the company. In a wireless environment, network reliability is a function both of the level of user congestion (traffic loads) and service availability (interference and coverage). At each intersecting cell, a list of privileges is created. This page contains Wireless Lan Security Seminar and PPT with pdf report. Users can be authenticated by something they know, something they have, or something they are. 802.11a b. With fully developed wireless LAN a user can hop around in a building but still be well connected to his data. “Something you are” can be established with fingerprint readers, retinal scanners, facial recognition systems, and hand geometry analyzers. Access control is the job of authorization systems. • WLANs offer a quick and effective extension of a wired network or standard LAN. Wireless local are network security (WLAN security) is a security system designed to protect networks from the security breaches to which wireless transmissions are susceptible. There are a number of basic fundamentals that a person or company needs to be aware of when deploying a wireless network. Wireless network security is the process of designing, implementing and ensuring security on a wireless computer network. The final proof-of-concept system consisted of two camera nodes and a base station that together formed a functional wireless mesh network. The first is a basic understanding of what frequencies will be used by the equipment being deployed; this is very important when deploying a wireless network as it affects the amount of interference that the network will be subject to depending on the specific environment.

Authentication is the foundation technology for protecting networks, servers, client systems, data, and applications from improper disclosure, tampering, destruction, and other forms of interference. In the digital world, software processes exchange data at a sort of least common denominator level without these physical clues, and authenticating the identification of a person bound to a software process is a tricky problem. A simple jamming transmitter can make communications impossible.
