CHAPTER
19	Voice over IP (VoIP) and PBX Security

Although often overlooked even by large organizations, the security of enterprise voice, telephony, and streaming multimedia systems (such as video conferencing and webcast and multicast systems) is a critical component of a sound overall security strategy that deserves special consideration. Attackers have been targeting computing systems for the last 25 years or so using intentionally exploitative behavior such as hacking and denial of service attacks. However, telephony exploits (originally referred to as phone phreaking but now included as part of mainstream hacking) have been used by clever individuals and organizations as far back as the 1960s to do everything from gaining free ...
