Design and Implementation of Personal Firewalls for Handheld Devices

Overview

Personal Digital Assistants (PDAs) have become one of the important tools in the life. Their popularity is due to their small size and mobility which enables them to be carried anywhere. Along with their popularity, handheld devices are starting to become the target for the attackers, who are mainly interested in gaining the data stored in handheld de-vices. Therefore, security of handheld devices has attracted a lot of attention in an effort to protect the sensitive information stored in handheld devices. Securing handheld de- vices is a daunting task. It requires a careful design since the devices have very limited computational power and battery life. This paper aims to review the security threats to handheld computers and propose several possible solutions.
