Techopedia Explains Wireless Network Security
Wireless network security is primarily concerned with safeguarding a wireless network from unauthorised and malicious attempts to gain access. Most of the time, wireless network security is provided by wireless devices (typically a wireless router/switch), which by default encrypt and secure all wireless communication. Even if the security of the wireless network is breached, the hacker will not be able to view the content of the traffic/packets in transit due to the encryption used. Furthermore, wireless intrusion detection and prevention systems (WIDS) enable the protection of a wireless network by notifying the wireless network administrator in the event that a security breach occurs.
Wired Equivalent Policy (WEP) and Wireless Protected Access (WPA) are two of the most widely used algorithms and standards for ensuring the security of wireless networks (WPA).
