In today’s internet use, wireless network technologies rather than wired systems provide far more practical, comfortable and fast connectivity. However, although wireless network systems have come into widespread use, the security vulnerabilities in these systems are also steadily increasing. For this reason, wireless network security testing must be carried out in order to determine the security of the system in use at institutions, businesses and companies.
Serious intrusions can be carried out against the wireless network systems within an organisation’s network infrastructure, and these attacks can cause major damage by reaching information held inside the organisation. Through wireless network security testing, a simulation is therefore used to perform an authorised intrusion and identify the weak points in the network.
When weaknesses are identified by carrying out an intrusion against a wireless network, methods and reports can be prepared explaining how those weaknesses should be remediated. In this way the work eliminates the weaknesses in a manner that can prevent an attacker from entering the system.
During wireless network security testing at an organisation, both the corporate wireless network and the guest network are generally tested separately, because it is sometimes possible to move from the guest network onto the local network, and isolation and bypass techniques can be applied. The test proceeds in distinct stages, including discovery of networks, examination of interfaces, reconnaissance, identification of security weaknesses, attack simulations and denial-of-service simulations.
