Wireless LAN Vulnerabilities? Threats and Countermeasures

Introduction

Wireless networking presents numerous benefits Productivity advances because of expanded accessibility to data resources. Network configuration and reconfiguration is simpler? much quicker? and less expensive. However? wireless expertise furthermore conceives new risks and adjusts the living data security risk profile. For demonstration? because communications takes location "through the air" utilising wireless frequencies? the risk of interception is larger than with connected networks. If the note is not encrypted? or encrypted with a feeble algorithm? the attacker can read it? thereby compromising confidentiality. Although wireless networking adjusts the dangers affiliated with diverse risks to security? the general security objectives stay the identical as with connected networks: maintaining confidentiality? double-checking integrity? and sustaining accessibility of the data and data systems. The target of this paper is to aid managers in making such conclusions by supplying them with a rudimentary comprehending of the environment of the diverse risks affiliated with wireless networking and accessible countermeasures.

The attractiveness of wireless Networks is a testament mainly to their convenience? cost effectiveness? and alleviate of integration with other systems and mesh components. The most of computers traded to buyers today arrive pre-equipped with all essential wireless Networks technology. The advantages of wireless Networks include: Convenience? Mobility? Productivity? Deployment? Expandability and Cost.

Wireless Network expertise? while replete with the conveniences and benefits recounted overhead has its share of downfalls. For a granted networking position? wireless Networks may not be attractive for a number of reasons. Most of these have to do with the inherent limitations of the technology. The handicaps of utilising a wireless mesh are:

Security? Range? Reliability? and Speed.

Wireless Networks present an owner of matters for mesh managers. Unauthorized get access to points? broadcasted SSIDs? unidentified positions? and spoofed MAC locations are just a couple of the difficulties addressed in WLAN troubleshooting. Most mesh investigation vendors? for example Network Instruments? Network General? and Fluke? offer WLAN troubleshooting devices or functionalities as part of their merchandise line.

The wireless systems comprise of four rudimentary components: The transmission of facts and numbers utilising wireless frequencies; Access points that supply an attachment to the organizational mesh and/or the Client apparatus (laptops? PDAs? etc.); and ...
