If a WLAN infrastructure is not administered centrally, access points left in their default settings will mostly be pre-configured with insufficient security mechanisms (or none at all). For example, if a lack of regulations leads an employee to connect an unauthorised or unsecured access point to an organisation’s internal network, this can lead to serious problems. Doing so will undermine practically all the security safeguards taken within the LAN in question, such as the firewall that is meant to protect the LAN against unauthorised external access.
