VoIP Security Vulnerabilities - a SANS GIAC paper
Last updated: Apr 17, 2020
The SANS Institute just posted an interesting paper by David Persky on VoIP security here. Although there is a growing number of papers and articles on VoIP security, but its very hard to find one that when stripped out of the marketing fluff, has any useful information at all. This paper on the other hand presents specific examples and has some real content.
