WLAN Security: Threats And Countermeasures

JOIV : International Journal on Informatics Visualization

A wireless local area Network (WLAN) is being widely recognized as a viable cost effective general purpose solution in providing high speed real time access to information. With a WLAN, users can gain access to shared information without being bound to fixed plug-in-point. WLAN transmit and receive data over the air and thus collectively combine data connectivity with ease of mobility. WLAN provides wireless access to multi location enterprises, small and medium enterprises. It can replace wired LAN or simply be used as extension of wired infrastructure. Besides all these advantages WLAN are also facing major problems of security.So security is the aspect where most of the researchers are working. Following are the major objective of our study : i) To study the various Vulnerabilities and attacks on WLAN and their solutions. ii) To study the some of the exiting security methods used for securing WLAN and explore the possibility of improvements in the same. Our conclusion that WLAN s...

Analysis of Security Issues and Their Solutions In Wireless LAN

—This paper begins by introducing the concept of wireless LAN (WLAN). The introductory section gives brief information on the WLAN components and its architecture. In order to examine the WLAN security threats, this paper will look at both active & passive attacks. The paper will then explain the security & flaws of legacy IEEE802.11 WLAN standards. This situation leads to further research regarding practical solutions in implementing a more secured WLAN. This paper will also cover the new standards to improve the security of WLAN such as the IEEE 802.1x standard, which comprises of three separated sections: Point-to-Point Protocol (PPP), Extensible Authentication Protocol (EAP) and 802.1x itself. Then the paper look for a newly proposed standard i.e. 802.11i for key distribution and encryption that will play a big role in improving the overall security capabilities of current and future WLAN networks. Finally, this paper ends with the conclusion of highlighted issues and solutions.

2016

— The rapid proliferation of wireless networks and mobile computing applications has changed the landscape of network security, the wireless networks have changed the way business, organizations work and offered a new range of possibilities and flexibilities; It is clear that wireless solutions are transforming the way we work and live. Employees are able to keep in touch with their e-mail, calendar and employer from mobile devices, but on the other hand they have introduced a new security threat. While an attacker needs physical access to a wired network in order to gain access to the network and to accomplish his goals, a wireless network allows anyone within its range to passively monitor the traffic or even start an attack. One of the countermeasures that can be used in order to allow us to know both the threats affecting our wireless network and our system vulnerabilities is the Intrusion Detection System. WLANs have a number of security-related issues. They are as follows:

Motivated by the need to reduce IT costs while increasing employee productivity; enterprise-wide wireless local area network (LAN) solutions are becoming increasingly viable. Proliferation of mobile Computing devices has boosted employee demand for access to their organization's network beyond the tether of their office workstation. Meanwhile, accelerated wireless transmission rates and increasing vendor adherence to standards-based interoperability are enhancing the practicality of wireless LANs. Yet the same wireless technologies that can erase the physical limitations of wired communications to increase user flexibility boost employee productivity, and lower cost of network ownership also expose network-based assets to considerable risks. The security embedded in wireless LAN technologies falls short of providing adequate protection. Early-adopting organizations have found that evaluating, and where possible, mitigating these risks before deploying a wireless LAN is beneficial. This white paper summarizes wireless network security planning by providing an overview of the security risks and technical challenges in this area, as well as summarizing key recommendations for secure wireless LANs.

An Overview of Wireless Local Area Networks (WLAN)

Wireless Communication is an application of science and technology that has come to be vital for modern existence. From the early radio and telephone to current devices such as mobile phones and laptops, accessing the global network has become the most essential and indispensable part of our lifestyle. Wireless communication is an ever developing field, and the future holds many possibilities in this area. One expectation for the future in this field is that, the devices can be developed to support communication with higher data rates and more security. Research in this area suggests that a dominant means of supporting such communication capabilities will be through the use of Wireless LANs. As the deployment of Wireless LAN increases well around the globe, it is increasingly important for us to understand different technologies and to select the most appropriate one . This paper provides a detailed study of the available wireless LAN technologies and the concerned issues ,will give a brief description of what wireless LANs are ,the need of Wireless LAN ,History of wireless LAN , advantages of Wireless Networks ,with summarizing the related work on WLAN in academic area , Wireless LAN technologies , some risks attacks against wireless technologies , suggesting some recommendations to protect wireless LAN network from attack , Finally we propose some research issues should be focused on in the future.

Wireless Local Area Network Security

Wireless Local Area Network (WLANs) has been generally utilized as a part of numerous areas. WLANs permit PCs to be fewer links, portable and correspond with close speed to the velocities of wired LANs. The prominence of increased because of numerous reasons, for example, simplicity of establishment, adaptability, portability, lessened expense, and versatility. It addresses sensible security assaults like man-in-the-centre assault and Refusal of Administrations assaults and additionally physical security assaults like rouge`s APs. Wired Equal Protection (WEP) was the first consistent answer for secure WLANs. Be that as it may, WEP endured numerous issues which were somewhat understood by IEEE802.1x convention. At last, this paper closes with the Proposals.

Wireless LAN Security: The IEEE 802.11 Risks and Technical Challenges

 Abstract— Wireless local area networks (LANs) are playing a major role in the information technology revolution. They have found their way into a wide variety of markets including financial sectors, corporations, health care, and education.The rapid deployment of wireless LANs is testimony to the inherent benefits of this technology. Unfortunately, most wireless deployments are, at this time, fundamentally insecure. This is not an exaggeration. It is an accurate assessment of the reality of the current state of the security of wireless 802.11-based environments.Because of its transmission characteristic, many security problems have set in. This paper aims to introduce the security mechanism of the wireless LAN and points out the shortcoming of it. Index Terms—About four key words or phrases in alphabetical order, separated by commas.
