Voice over IP solution

Solutions for highly available VoIP infrastructures:

This part of the work will in the first stage investigate points of failure of a VoIP infrastructure and provide solutions for achieving highly available components based on distributed architectures. The objectives of this part of the works are thereby:

• Identify and describe points of failure in a VoIP infrastructure
• Identify monitoring points and possible alarm utilities for indicating failures and initiating needs recovery mechanisms
• Provide solutions for supporting high available VoIP infrastructure at low costs

Solutions and tools for secure VoIP infrastructures:

This part of the work will concentrate on increasing the availability of VoIP infrastructure by reducing the effects of denial of service attacks. The objectives of this part of the work will thus be:

• Design and implement a framework for secure VoIP calls to avoid fraud and malicious usage
• Specify and develop tools for Intrusion and denial of service attack detection
• Support automatic reaction to security threats based on provider specific rules
• Integration and testing of developed tools and solutions in a provider’s VoIP infrastructure

SNOCER is an research project supported within the Sixth Framework Programme of the EU Commission.

The project acronym stands for " Low Cost Tools for Secure and Highly Available VoIP Communication Services ", and as the name indicates the project has a profound emphasis on securing VoIP infrastructure.

The solutions investigated in the SNOCER project will lead to the development of security enhancement tools that allow the service provider to monitor the network, detect irregularities such as a denial of service attack or failure of a certain component and taking the appropriate measures to handle these irregularities. These tools will further offer the service provider with the appropriate means for specifying customized rules for enforcing provider specific security policies.

Thereby small and medium enterprises entering the VoIP market and aiming at providing VoIP services coupled with their own innovative solutions would be offered effective and yet low cost solutions for securing their VoIP infrastructure and ensuring the reliability and high availability of their services.

The SNOCER project has a duration of 24 months, and started out November 1st 2004. The project has 6 partners.
