VoIP Vulnerability Assessment and Penetration Testing

Discovering the security flaws in your VoIP infrastructure to secure from external attacks

VoIP (Voice over Internet Protocol) has become important for businesses and hence a good option for the attacker to exploit whenever left unprotected. Unlike other IT infrastructure, VoIP is also subjected to risks like interception, caller ID spoofing, Denial of Service (DoS) etc.

VoIP security is not only about call encryption, it is the level of trust that's conveyed over the text and voice network. If it is compromised, it can become a huge threat by carrying out more attacks.

A VoIP security assessment is a manual assessment of the security of the VoIP infrastructure. It identifies the vulnerability in the VoIP system to reduce the risk of financial loss or unauthorized access.

VoIP security assessment generally includes- 

 

1. Application-level vulnerabilities 

2. Extension enumeration and number harvesting 

3. Default credentials testing 

4. Voicemail security testing 

5. Traffic capture and eavesdropping

6. Caller ID spoofing 

7. Identifying DoS vulnerabilities 

8. Design and configuration issues 

 

 

How is VoIP security assessment performed?

The general approach is to gain access into the network and identify the vulnerabilities which are explained in the steps below - 

 

1. Information gathering - Gathering all the possible information about the IP of servers, VoIP devices, PSTN's signalling system etc. 

 

2. Enumeration - Gathering information about services running in the environment. 

 

3. Vulnerability analysis - Identifying the vulnerabilities in the devices, services and infrastructure. 

 

4. Attacking - Exploiting the vulnerabilities to gain access and accessing the scope of attacks

 

5. Report and Support - Presenting a detailed report on the vulnerabilities found with their strength, risk and standard associated with the security. Assisting in deploying the mitigation strategies as suggested in the assessment.  

 

 

It is important to resolve the flaws as early as possible as the slightest negligence can result in severe financial and property losses. Application of required regulations for every business using VoIP infrastructure.
