IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing
Wired security modules a very challenging job. These characteristics create a well secured protocol that is almost equivalent to The wireless environment is more challenging to safeguard because of This section will discuss various steps in wireless LAN security with significant review of its current status of Support of prior work being carried out in the direction of securing wireless LAN. This paper discusses about the various trends of security protocols, their strength and weakness with the

Is just a tad cleverer than "reasonably clever," he or she may also be able to download and read the contents of the In fact, if the person intercepting the wireless data Reasonably clever person can still intercept your data packets.

Using a password to restrict entry to your network may not provide enough protection, since a This first-hand, since it is often possible to pick up signals from wireless access points located in nearbyĪpartments. People who use laptops that have a wireless LAN card will know Pass through walls, floors, and other barriers. This isīecause the radio waves used to transmit data packets between user computer and the wireless access point can The sophisticated procedure of encryption is one of the most crucial parameter in WLAN technology. The authentication server also takes responsibility for computing the "keys" that the encryption algorithm will In effect, the authenticator and authentication server work as a team to confirm the identity of the supplicant node. Supplicant (Client) Authenticator (Access Point) Authenticator Server (RADIUS) Was also found that majority of the application uses RADIUS server.įigure 1 Authentication of IEEE 802.1x (WLAN) Fig.1 signifies the association of supplicant, authenticator, and server. Plays the role of gatekeeper, and iii) The authentication server, which connects to the router over a wired network, Through the wireless network, ii) The authenticator, which for a wireless network is usually an access point (AP),

Supplicant is the client (for example, PC or laptop computer) who would like to gain access to network resources The 802.1x authentication procedure involves three basic players: i) The Involved in the authentication process gain access to each other's resources by connecting through "ports." InĮffect, the authentication procedure involves placing a "guard" node at each port to thwart illegal users from IEEE 802.1x verifies use of port-based access control that means the various entities Phenomenon of encryption performs encoding of the data so that anyone who does not have the secret "key" will Is supposed to be permitted for an access to the data and resources furnished by the protected network. A wireless system mechanizes authentication to evaluate user's credentials and resolve if the user There are two critical parameters of securing WLAN e.g. IEEE 802.11 standards that discusses about the usage as well as security mechanism to be performed over the Formulation of such networking system is governed by Network (LAN) through a wireless (radio) connection. Keywords: Attacks in WLAN Security PSK Wireless Local Area Network WPA WEP.Ī wireless LAN (or WLAN) is a type of wireless connection where a mobile user can connect to a local area
The overall outcome of this review paper is that frequently used security protocols are not as robust and sufficient enough to mitigate the possible lethal threats in wireless LAN. This paper presents some of the effective security protocols right from evolution to existing scenario and discusses various pros-and-cons of security protocols in WLAN with respect to its countermeasure techniques on various attacks. The past decade has witnessed various formulations of security protocols which claims to address the breaches in IEEE 802.11 standards. With the availability of expensive network and security devices, such attacks are yet hard to be mitigated. However, various sophisticated attacks like jamming attack, flooding attack, WPA-PSK Attack etc are still on the rise. Majority of the corporate and institutional establishment uses WLAN as it is highly cost-effective and convenient to use. Prof.: Dept of Information Science EngineeringĪbstract: The area of wireless networking is always shrouded by security loopholes where security in Wireless Local Area Network (WLAN) is still yet to be witnessed some full-fledge security incorporation.
