VoIP hacker secrets revealed

'Hacking ExposedTM VoIP: Voice Over IP Security Secrets and Solutions’, published by McGraw-Hill, details specific threats to enterprise VoIP networks and provides remediation advice.

According to co-author Mark Collier, who doubles as chief technology officer at US-based telecoms security vendor SecureLogix, the authors’ goal in writing the book was to provide network administrators with an insight into the tools and methods of VoIP hackers.

His co-author, David Endler, director of security research at global network security vendor TippingPoint, added that the inclusion of VoIP in last month’s SANS top 20 report indicated the growing security threats posed to the technology.

To provide practical examples for security professionals, Endler and Collier developed and demonstrated real-world VoIP attack scenarios that hackers will likely use in enterprise VoIP attacks.

Commenting on the book, Ron Gula, CTO of security vendor Tenable Network Security, said VoIP networks were not as secure as many administrators thought.

“The book illuminates how remote users can probe, sniff, and modify your phones, phone switches, and networks that offer VoIP services,” he said in a statement.
