Portable electronic communication devices can be used for many purposes and they are capable of integrating with Ubiquitous Computing (UC) infrastructures to carry on mobile multimedia communications. As those devices become prevalent, they incur potential network security threatening to organizations. Nowadays, the Skype is the most popular P2P VoIP application program, which is being used by millions of global users to place IP phone calls, transfer files, or communicate via Instant Messaging (IM). This phenomenon already generates imminent network security issues that are indispensable to digital forensics researchers or the law enforcement agencies worldwide.
