Portable devices, such as Personal Digital Assistants (PDAs), are particularly vulnerable to malicious code threats due to their widespread implementation and current lack of a security framework. The presented research provides detail into specific scenarios, weaknesses, and mitigation recommendations related to data protection, malicious code, virus storage, and virus propagation.
