Design and optimize firewall for mobile networks

More and more activities (such as e-commerce, e-learning, e-chat, etc.) rely on mobile devices. It becomes an important issue on how to protect mobile users engaged in mobile services. A firewall is one of the security solutions. Unfortunately, conventional firewalls are inappropriate for mobile networks because of the limited computing and communication capabilities of mobile devices. We introduce the issues to be considered in designing a mobile firewall and compare two existing mobile firewall solutions. Then we evaluate the performance of a mobile firewall, and finally propose an optimized mobile firewall scheme.
