Fast Rtp Detection And Codecs Classification In Internet Traffic, Petr Matousek, Ondrej Rysavy, Martin Kmet
Fast Rtp Detection And Codecs Classification In Internet Traffic, Petr Matousek, Ondrej Rysavy, Martin Kmet
Journal of Digital Forensics, Security and Law
This paper presents a fast multi-stage method for on-line detection of RTP streams and codec identification of transmitted voice or video traffic. The method includes an RTP detector that filters packets based on specific values from UDP and RTP headers. When an RTP stream is successfully detected, codec identification is applied using codec feature sets. The paper shows advantages and limitations of the method and its comparison with other approaches. The method was implemented as a part of network forensics framework NetFox developed in project SEC6NET. Results show that the method can be successfully used for Lawful Interception as well …
Is There A Role For Common Carriage In An Internet-Based World?, Christopher S. Yoo
Is There A Role For Common Carriage In An Internet-Based World?, Christopher S. Yoo
All Faculty Scholarship
During the course of the network neutrality debate, advocates have proposed extending common carriage regulation to broadband Internet access services. Others have endorsed extending common carriage to a wide range of other Internet-based services, including search engines, cloud computing, Apple devices, online maps, and social networks. All too often, however, those who focus exclusively on the Internet era pay too little attention to the lessons of the legacy of regulated industries, which has long struggled to develop a coherent rationale for determining which industries should be subject to common carriage. Of the four rationales for determining the scope of common …
Extraction Of Electronic Evidence From Voip: Identification & Analysis Of Digital Speech, David Irwin, Arek Dadej, Jill Slay
Extraction Of Electronic Evidence From Voip: Identification & Analysis Of Digital Speech, David Irwin, Arek Dadej, Jill Slay
Journal of Digital Forensics, Security and Law
The Voice over Internet Protocol (VoIP) is increasing in popularity as a cost effective and efficient means of making telephone calls via the Internet. However, VoIP may also be an attractive method of communication to criminals as their true identity may be hidden and voice and video communications are encrypted as they are deployed across the Internet. This produces a new set of challenges for forensic analysts compared with traditional wire-tapping of the Public Switched Telephone Network (PSTN) infrastructure, which is not applicable to VoIP. Therefore, other methods of recovering electronic evidence from VoIP are required. This research investigates the …

Extraction Of Electronic Evidence From Voip: Forensic Analysis Of A Virtual Hard Disk Vs Ram, David Irwin, Jill Slay, Arek Dadej, Malcolm Shore
Journal of Digital Forensics, Security and Law
The popularity of Voice over the Internet Protocol (VoIP) is increasing as the cost savings and ease of use is realised by a wide range of home and corporate users. However, the technology is also attractive to criminals. This is because VoIP is a global telephony service, in which it is difficult to verify the user’s identification. The security of placing such calls may also be appealing to criminals, as many implementations use strong encryption to secure both the voice payload as well as to control messages making monitoring such VoIP calls difficult since conventional methods such as wire-tapping is …
Developing Voip Honeypots: A Preliminary Investigation Into Malfeasant Activity, Craig Valli
Developing Voip Honeypots: A Preliminary Investigation Into Malfeasant Activity, Craig Valli
Journal of Digital Forensics, Security and Law
30 years ago PABX systems were compromised by hackers wanting to make long distance calls at some other entities expense. This activity faded as telephony became cheaper and PABX systems had countermeasures installed to overcome attacks. Now the world has moved onto the provision of telephony via broadband enabled Voice over Internet Protocol (VoIP) with this service now being provided as a replacement for conventional fixed wire telephony by major telecommunication providers worldwide. Due to increasing bandwidth it is possible for systems to support multiple voice connections simultaneously. The networked nature of the Internet allows for attackers of these VoIP …
Regulatory Status Of Voip In The Post-Brand X World, Jerry Ellig
Regulatory Status Of Voip In The Post-Brand X World, Jerry Ellig
ExpressO
During the past several years, the Federal Communications Commission has engaged in a series of rulemakings to determine the regulatory status of Voice over Internet Protocol (VoIP). The Supreme Court’s Brand X decision clarifies that even if the FCC’s determination conflicts with that of a court, the FCC’s judgment holds sway as long as the decision is reasonable. We believe that VoIP should be classified as an information service, rather than a telecommunications service, for several reasons. First, the Internet Protocol nature of VoIP technology means that it functions like an information service, rather than a telecommunications service. Second, in …
A Model For Emergency Service Of Voip Through Certification And Labeling, Patrick S. Ryan, Tom Lookabaugh, Douglas Sicker
A Model For Emergency Service Of Voip Through Certification And Labeling, Patrick S. Ryan, Tom Lookabaugh, Douglas Sicker
ExpressO
Voice over Internet Protocol (VoIP) will transform many aspects of traditional telephony service, including the technology, the business models, and the regulatory constructs that govern such service. Perhaps not unexpectedly, this transformation is generating a host of technical, business, social, and policy problems. In attempting to respond to these problems, the Federal Communications Commission (FCC) could mandate obligations or specific solutions to VoIP policy issues; however, it is instead looking first to industry initiatives focused on the key functionality that users have come to expect of telecommunications services. High among this list of desired functionality is user access to emergency …
