Voice Over IP

Introduction

VoIP is one of the most compelling current trends in the telecom industry. But the complexities of implementing VoIP security is often not well understood. This datasheet provides an overview of the important issues surrounding VoIP, particularly its use as a communications medium for services to the enterprise. TeleDesign Security assesses the real opportunities for new services and consults with clients, service providers and vendors on how to maximize their gain while maintaining optimum security.

Converged voice and data networks offer greater flexibility and savings to organizations than do traditionally segmented voice and data infrastructures. Additional measures and emphasis are required in order to ensure the confidentiality, integrity and reliability of not only the components, but the services provided by converged Voice over IP (VoIP) networks as well. Security of these converged solutions represents an even higher concern to corporations than return on investment (ROI), and is the primary reason for hesitation in adopting these new technologies.

Proper implementation of network security controls, both policies and technology, is needed to prevent intentional attacks against a VoIP solution. These controls minimize unintentional mistakes, prevent unnecessary exposure of information assets, and reduce the impact of attacks focused at data and voice networks.

During the consulting engagement, TeleDesign Security (TSI) network security and convergence consultants work together to support the delivery of a secure VoIP environment. All data collected during this engagement is analyzed to determine the current security posture.   TSI then provides recommended solutions to implement the security measures necessary to accommodate and support your organizational needs, identify any potential threats and provide mitigating solutions to the areas of highest risks.

TSI provides our customers with a comprehensive approach to meeting the demands of securing a converged infrastructure. Our comprehensive Plan, Design, Implementation and Optimization methodology allows us to build, secure, and provide management capabilities for converged solutions from beginning to end, or any point within the lifecycle of the project.  Additionally, TSI’s VoIP Security Solution can be leveraged to enhance any available security approaches existing within the current converged networks. TSI is a vendor-independent organization and skilled in providing secure solutions for any VoIP implementation.

We approach VoIP Security in four phases:

Phase I: Architecture and Security Assessment

Using our certified security assessment methodologies and technical VoIP assessment, TSI consultants evaluate your existing infrastructure and security posture.

Phase II: Planning and Design

Based on the information collected from the first phase, TSI develops a comprehensive VoIP architecture that is secure and meets your business requirements.

Phase III: Secure VoIP Implementation

Leveraging our extensive experience in telecommunications, internetworking, convergence technologies and security, TSI consultants deliver a complete implementation plan, including requirements and an overall project plan to deploy the approved recommended technology and infrastructure changes.

Phase IV: Security Management and Operations

Managing security is an ongoing process. To ensure continued security is realized for the life of the VoIP solution, TSI will offer recommendations for developing security policies specific to the solution and incident management capabilities. The solutions will be specifically defined and integrated to help customers address the variety of threats to their converged networks.
