Abstract

Wireless local area network or WLAN more vulnerability than wired network even though WLAN has many advantages over wired. Wireless networks use radio transmissions to carry data between end users and access point. Therefore, it is possible for someone to sit in your office building's lobby or parking lot or parking lot to eavesdrop on the wireless network communication. This paper discussed securing wires local area network used WPA2 Enterprise based PEAP MS-CHAP and Captive portal firewall. We also divided the network for employer and visitor to increase the level of security. Our experiment showed that the WLAN could be broken using the attacker tool such as airodump, aireply, and aircrack.

Highlights

Wireless communication is exchange of information between two or more devices that are not connected by an electrical conductor
wireless local area network (WLAN) can overcome the problem of lack of wired network, because it has the advantage, as follows: x Mobility: WLAN users can gain access to internet at anywhere from one access point to another access point, without preparing cable or network infrastructure. x Scalability: WLANs can be configured to different topology depending on the needs of the system
We proposed WLAN security used WPA2 enterprise base on Protected Extensible Authentication Protocol (PEAP)-MS-CHAP and firewall captive portal

Summary

Introduction

Wireless communication is exchange of information between two or more devices that are not connected by an electrical conductor. A wireless local area network (WLAN) links two or more devices over a short distance using a wireless distribution method, usually providing a connection through an access point for internet access. Technologies may allow users to move around within a local coverage area, and still remain connected to the network [1], [2]. Using Wireless Local Area Network users can access internet without pulling the cable network. WLAN can overcome the problem of lack of wired network, because it has the advantage, as follows: x Mobility: WLAN users can gain access to internet at anywhere from one access point to another access point, without preparing cable or network infrastructure. Simplicity of installation is more cost effective, network setup and installation do not need to use of cables
