Abstract

There is disclosed a security apparatus, for use in a wireless network comprising base stations that communicate with mobile stations, for preventing unprovisioned mobile stations from accessing an Internet protocol (IP) data network via the wireless network. The security apparatus comprises a database that stores a first server IP address of a first provisioning server in the wireless network, and a first controller for receiving a first IP data packet transmitted by a first mobile station, wherein the first IP data packet comprises a first source IP address and a first destination IP address. The first controller determines if the first mobile station is provisioned and transmits the first IP data packet to the IP data network if the first mobile station is provisioned. If the first mobile station is unprovisioned, the first controller transmits the first IP data packet to the IP data network if the first destination IP address matches the first server IP address and prevents transmission of the first IP data packet to the IP data network if the first destination IP address does not match the first server IP address.
