VOIP Penetration Testing Checklist

VoIP (Voice over Internet Protocol) penetration testing is a process of assessing the security of a VoIP system, which includes VoIP servers, endpoints, signaling protocols, and data transmission channels. The main objectives are to identify vulnerabilities, misconfigurations, and weaknesses in VoIP infrastructure, preventing unauthorized access, data leakage, and disruptions.

Objective: Ensure that the underlying network is secure and properly segmented.

Tests:

Network Segmentation: Verify that VoIP traffic is isolated from other traffic to reduce attack surfaces.Firewall Configuration: Check firewall rules to ensure only necessary ports and protocols are allowed.QoS & VLAN Configuration: Test for vulnerabilities in Quality of Service (QoS) settings and VLAN configurations that may impact VoIP quality or security.Tools: Nmap, Wireshark, and network scanners.
