Keeping Intruders Out Of Your WLANMarch 8, 2008 – 4:00 PM
Wireless LANs utilize radio waves for transporting information, which results in security vulnerabilities that justifiably worry network managers. To assuage those worries, most companies implement authentication and encryption to harden security. However, WLANs have a whole host of other vulnerabilities that can be more difficult to completely smother such as illicit monitoring, unauthorized access, and denial of service (DoS) attacks. For example, someone using a wireless sniffer, such as the freely-available NetStumbler, can easily monitor wireless traffic for fun or malicious intent while sitting in their car next to your office building.
Fortunately, intrusion detection systems (IDSs) can secure networks against these threats.
