1. VoIP Security Threats and Countermeasures
Speaker: Eric Y. Chen (NTT Information Sharing Platform Laboratories)
Abstract & Biography:
The VoIP technology has been increasingly popular and the number of its users has surged in the past years, because of its economical advantage over the traditional PSTN services. As a side effect, various VoIP servers and clients are becoming attractive targets of malicious attacks. This presentation introduces major security threats against VoIP and discusses possible countermeasures using the technology available.
Biography: Eric Chen has been a researcher at NTT Information Sharing Platform Laboratory in Japan since 1997. He received his Ph.D. in computer science from the University of Tokyo and MBA from McGill University in Canada. He has served in the Technical Advisory Board of VoIP Security Alliances (VOIPSA) and the technical program committee in conferences such as IPTCOMM, SIGCOMM LSAD and SAINT. His current research interests include VoIP security, SPIT and DDoS attacks.


2. Advanced Flooding attack on a SIP Server
Speaker: Ms Xianglin Deng, University of Canterbury, Malcolm Shore, Technology Strategist, Telecom NZ Ltd, and Adjunct Senior Fellow, University of Canterbury
Abstract & Biography:
SIP is a lightweight application layer protocol designed to manage and establish multimedia sessions, such as those required in video conferencing, Voice over IP telephony, messaging, and data sharing. SIP servers are vulnerable to denial of service (flooding) attacks, and are typically located inside the corporate LAN behind a firewall with SIP flooding protection. In this paper, we demonstrate how such firewalls can be defeated and a SIP flooding attack achieved, and then describe a firewall mechanism to counter this form of attack. A further improvement involving enhancements to the SIP server is also described and test results detailed. This work has involved use of the innovative JAIN SLEE environment to develop an enhanced SIP Server, and the advantages of this environment are discussed.
Biography: Ms Xianglin Deng. Ms Xianglin Deng came from Chengdu, Peoples Republic of China in 2002 to undertake graduate studies in telecommunications at Otago University. Upon graduating with first class honours, she moved to Canterbury University to do further post graduate studies. Xianglin obtained a scholarship from Telecom NZ and MediaLab Ltd to support her Master's degree, which is in the area of SIP Flooding attacks with a strong focus on VoIP architectures.

Dr Malcolm Shore: Dr Shore emigrated from the UK to New Zealand in 1974 and in 1976 took a commission in the RNZAF. His career involved applications and systems programming followed by a policy/planning position in Defence Headquarters. Malcolm retired from the RNZAF and took a position with the Government Communications Security Bureau as Manager Computer Security followed by appointment to Director Information Systems Security. During this time, Malcolm completed his PhD at Otago University. Subsequent to his government service, Dr Shore has been involved with the design and development of commercial voice, satellite, and radio cryptographic products. He current is a technology strategist for Telecom NZ and holds an adjunct position as Senior Fellow in the Computer Science and Software Engineering department of Canterbury University, where he lectures in Computer Forensics and Information Warfare, and a position as Guest Professor to Wuhan University, China.


3. Current Practices and Outlook for SIP Security
Speaker: Nate Klingenstein, Internet2
Abstract & Biography:
Abstract: SIP is a protocol used primarily for video and audio conferencing. While spam was at one time confined to text-based messaging systems, such as email and instant messages, there has been a growing prevalence of spam sending prerecorded videos to video conferencing systems. With limited authentication and authorization capabilities built into the core protocols, beyond the spam lie potential DoS, impersonation and registration attacks. This session will examine the functionality implemented in products, some deployed environments, and potentials for future research & development to give SIP better ways to fight these problems.

Biography: Nate Klingenstein is a member of the Shibboleth core team. His primary research interests include sharing identifiers and identities across domains, the nature of identity vs. identifier vs. attribute, holder-of-key federated identity, modeling externally facing enterprise middleware interfaces, and reputation-based trust webs. Research hobbies are economics, quantum physics, cosmology, large fish, peak oil, and biochemistry. He is actively involved in OASIS SSTC and other standards efforts.

5. Internal Enterprise Security: A holistic Approach
Speaker: Sureswaran Ramadass (Univ Sains Malaysia)
Abstract & Biography:
Abstract: Internal Enterprise Security is an issue that has now become a vital part of security for all small, medium and large scale organizations. ICT security initially covered the following areas:
* Server security
* Virus
* Defenses against attacks from the Internet.
Today, it is a well known fact that over 80% of security breaches happen from inside your network. With such statistics, it is obvious that there has to be a high level of security now in place within the enterprise network. But are there proper tools available to cater for such issues? This presentation talks about the work done by the iNet team to develop an all encompassing enterprise security tool called the J-Enterprise Suite.
It is a partially Open Source Security Development Platform built using Java.
In brief, the jNetmon Suite Covers the following areas:
* Network Monitoring and Protection Tool that can operate in a real time.
* A troubleshooting Tool that can detect Faults and threats causing performance and security issues in the network.
* Can operate and cover an entire enterprise level network.

Biography: Associate Professor Dr. Sureswaran Ramadass is an Associate Professor at the Universiti Sains Malaysia. He is also the Director of the National Advanced IPv6 Centre of Excellence (NAv6) as well as the Chairman of Mlabs Systems Berhad, a MESDAQ listed company.
