The wireless local area network (WLAN) has been widely used in many sectors. The popularity gained is due to many reasons, such as ease of installation, flexibility of installation, mobility, reduction of cost of ownership and scalability. However, regardless of the benefits, the WLAN has some security threats. Local wireless networks are network security (WLAN security) is a security system designed to protect networks from the security breaches to which wireless transmissions are susceptible. This type of security is necessary because WLAN signals do not have physical limitations of limits and are prone to illegitimate access to network resources, resulting in the vulnerability of private and confidential data. Network operations and availability can also be compromised in the event of a WLAN security outage. To address these problems, various authentication, encryption, invisibility, and other administrative control techniques are used in WLAN networks. Corporations and corporate WLANs, in particular, require adequate security measures to detect, prevent and block the piggybackers, spies and other intruders.
