SecureLogix CTO Releases Second Edition of Landmark Security Book, “Hacking Exposed: Unified Communications & VoIP”

Internationally Recognized Unified Communications Security Expert Exposes the Latest Threats to the Enterprise Voice Networks

SAN ANTONIO--()--SecureLogix today announced that the second edition of CTO Mark Collier’s landmark book, Hacking ExposedTM: Unified Communications & Voice Over IP Security Secrets and Solutions, Second Edition,” has just been published by McGraw-Hill and is now available. Editor’s Note: View video interview with author, Mark Collier, here:

This new edition to the Hacking ExposedTM network security book series focuses on “voice” or unified communication (UC) application security issues, with real-life scenarios of current attacks on enterprise networks, along with detailed recommendations for preventing these attacks. At least half of the material for this revised edition is entirely new and reflects the evolution of UC and VoIP security threats, with an emphasis on real-world attacks affecting enterprise networks. The remaining material was heavily revised to reflect changes since the previous edition.

UC and VoIP security threats have evolved, with the primary issue being the increased threat of malicious calls from the Public Voice Network (PVN). Attacks are easy to create, through the use of free PBX software such as Asterisk, calling number spoofing, call generators, and call origination through the Session Initiation Protocol (SIP). Attackers can easily create “robocalls,” used for Telephony Denial of Service (TDoS), harassing calls such as voice SPAM, new forms of toll fraud and service abuse, voice phishing or vishing, and social engineering for the purposes of financial fraud.

Subject matter covered in the book include

  • Foot printing
  • Scanning
  • Enumeration required to plan for attacks
  • Attacks against UC and VoIP networks to include eavesdropping
  • Infrastructure DoS
  • Man-In-The-Middle (MITM) attacks
  • Attacks unique to Cisco Systems
    • Application level attacks such as SIP and RTP fuzzing
    • Flooding
    • Manipulation

The book also includes a survey of issues with emerging technologies such as Microsoft Lync, other forms of communications, Over-The-Top (OTT) softphones, Cloud, new UC deployment models, and WebRTC.

“The Public Voice Network has become much more hostile and both enabled new attacks and made traditional voice attacks easier and cheaper to execute. While UC and VoIP add much new vulnerability, what they primarily do is allow the same attacks occurring in the past much more prevalent and disruptive,” commented Collier. “This includes attacks such as TDoS, which were never practical in the past, but are now rapidly increasing. The Public Voice Network will continue to get more and more hostile, eventually merging with the Internet. The attacks described in this book have a financial incentive behind them and can be expected to become more and more disruptive to enterprises.”
