Securing your wireless network

Introduction

Guide

Wireless local area networks (WLANs) are convenient, cheap and easy to install. They allow for mobility around the office and deliver great flexibility. However, all WLANs potentially have major flaws and weaknesses.

This guide describes the potential security issues in wireless networks that may affect your business - for example, the denial of service attacks, spoofing and session hijacking. Eavesdropping is also a concern with wireless transmission - others 'listening in' on your business activities and using this information against you, eg to undercut your prices.

Unless you set up suitable security measures, your corporate WLAN may be insecure. It may even compromise your business. To protect it, it is important to set up your wireless network components correctly, choose the right Wi-Fi protected access (WPA) and use the appropriate wireless networking standards.
