Critical Defence - Voice over IP

Voice over Internet Protocol (VoIP) Security Assurance

Confidentiality in voice communication is critical to the success of any government, business and institution. In today’s interconnected world, new hardware and software security vulnerabilities are uncovered daily. Implementing corrective precautions to prevent outsiders from gaining access to critical systems, data and confidential communication is a daunting task.

Communication over the Internet
Organizations continue to adopt Voice over IP (VoIP) communications systems because of their rich features, promise of lower costs, and ability to share infrastructure with their computer networks. As the popularity of VoIP grows, the more it will come under attack. Unfortunately, VoIP security is still in its infancy. Ongoing security assurance and testing exercises are key to maintaining the integrity of any VoIP solution.

Critical Defence VoIP security testing programs assist your organization by proactively testing and validating the security posture of VoIP implementations and infrastructures. Some of the key elements that are addressed during a VoIP security assurance program are:

Network segmentation (data, voice and management networks)
Net
Business continuity and redundancy
Voice and email integration
Scalability of the design
IP phone management
Patch management
Incident response

Without the correct controls in place, VoIP networks are potentially vulnerable to:

Traffic capture and session hijacking attacks
Reboot attacks
Vulnerabilities
Management interface attacks
Denial of service (DoS)
Spamming attacks

Possible consequences of VoIP attacks by malicious users include:

Eavesdropping
Content injection
Spoofing caller ID
Call and user redirection
Crashing phones
Denying phone service
VoIP Spamming
User Enumeration
