In this paper we have observed security mechanisms. Some of these issues are as follows: xThere is no common model to guaranteed securi- communication medium of wireless LAN is radio wave, thus it’s more susceptible to eavesdropping than wired networks, and as the wireless market grows, the security issues grow along with it. Spoofing Attackers Using Cluster Analysis in Wireless Network. Massachusets, California, USA. This paper discusses the various security issues and vulnerabilities related to the IEEE 802.11 Wireless LAN encryption standard and common threats/attacks pertaining to the home and enterprise Wireless LAN system and provide overall guidelines and recommendation to the home users and organizations. Moreover, Wireless Local Area Network (WLAN) can work in different bands at carrier frequency 2.4 GHz, 5 GHz or 60 GHz. The wireless networks are more vulnerable than wired networks because the data is transmitted through the broadcast radio technology, instead of a dedicated cable. Current high gain antennas on the market that meet these specifications are expensive and cannot cover a larger distance. Antenna a key element used to get better coverage. With the growing number and height of buildings as well as the number of users, it has become essential to apply new techniques to provide better wireless network services, especially for security issue with many applications used by an attacker that can decrypt the traditional password to use network resources, that’s lead to poor network performance for providing network services for people authorized to use it. Science Trends and Technology (IJCST), vol. This paper aims to introduce the security mechanism of the wireless LAN and points out the shortcoming of it. https://www.lifewire.com/introduction-to-intrusion-.

They expose the network to a new group of hackers. (MIMO) and 60 GHz MIMO signals simultaneously over Single Mode Fiber (SMF) using polarization multiplexing technique. These networks can be up and running quickly when there is no available wired Ethernet infrastructure. It is covered all the security issues and solutions to issues so that WLAN is protected like Wired LAN and make a comparisons between password based wireless network and RADIUS Server [22]. authentication, confidentiality and integrity problems. These differences affect how a secure channel can be established in a wireless environment. Besides all these advantages WLAN are also facing major problems of security. It discovered that Anche la riservatezza dei dati costituisce un’autentica preoccu-pazione per quanto riguarda le LAN wireless, perché non è possibile dirigere una trasmissione LAN wireless … There have been a variety of security issues raised in wired and wireless networks and security specialists proposed a variety of solutions.

In the mid 1990’s, the IEEE LAN/MAN committee began developing a series of Wireless Local Area Network (WLAN) standards. tion’s network LAN, wireless LAN, and WAN, using device configurations that are relevant across most network deployments without requiring significant implementation-specific tuning. in-depth comparative analysis of each of the security mechanisms is driven by D. Bilolikar and S.Y. This ensures efficient information sharing and boosts productivity. 346-350, There have been several works on WLAN security since it was discovered that the 802.11 security architecture is weak. As most wireless net- work standards have been designed with security as an af- terthought, severe security shortcomings were the results and several improvements and amendments were neces- sary to fix the worst. WPA2 made further, authentication/association packets from MAC addresses, key, and second, the attack to reveal the, information coming from an Access Point. Research in Computer and Communication Engineering, Vol. Communications in wireless networks remains a challenging and critical issue. Arbaugh. This article provides a detailed overview, analy- sis and discussion of state-of-the-art security mechanisms in wireless networks and brie°y presents their develop- ment and history allowing the reader to quickly gain de- tailed insight into the topic. — WLAN Security, Wireless Security, Wireless Countermeasure, Wireless Threats.
