CERT: Understanding Voice over Internet Protocol (VoIP)

Cyber Security Tip ST05-018 – Understanding Voice over Internet Protocol (VoIP): “Because VoIP relies on your internet connection, it may be vulnerable to any threats and problems that face your computer. The technology is still new, so there is some controversy about the potential for attack, but VoIP could make your telephone vulnerable to viruses and other malicious code. Attackers may be able to perform activities such as intercepting your communications, eavesdropping, conducting effective phishing attacks by manipulating your caller ID, and causing your service to crash. Activities that consume a large amount of network resources, like large file downloads, online gaming, and streaming multimedia, will also affect your VoIP service.”
