Wlan Security Policy Issues

In a wired local-area network (LAN), the network ports and cables are mostly contained inside a building. Therefore, a hacker must defeat physical security measures, such as security personnel, identity cards, and door locks, to be able to physically access the LAN. However, the penetration capability of electromagnetic waves exposes the datatransmission medium of a wireless LAN (WLAN) to potential intruders (Potter & Fleck, 2003).

WLAN security thus requires reliable protection of data communication between WLAN units and strong access-management mechanisms.
