Most of the computer security white papers in the Reading Room have been written by students seeking GIAC certification to fulfill part of their certification requirements and are provided by SANS as a resource to benefit the security community at large. SANS attempts to ensure the accuracy of information, but papers are published "as is". Errors or inconsistencies may exist or may be introduced over time as material becomes dated. If you suspect a serious error, please contact firstname.lastname@example.org.
This paper will describe Voice Over Internet Protocol (VoIP) to a level that allows discussion of security issues and concerns. Business concerns of implementing VoIP, components of a VoIP system, and relevant security issues and concerns as they apply to the topics, are explored.
It is clear that a great deal of time is spent in creating and maintaining these courses. Content is well presented, relevant and accurate. Delivery is meaningful and energetic. -Sue Farrand, Edgewater Technology Associates
