How do you handle VoIP security concerns, such as eavesdropping and denial of service attacks?

Your Answer

How To Answer This Question?

When answering this question, it's important to demonstrate your understanding of the specific security threats to VoIP systems and the measures you can take to mitigate them. Start by explaining the nature of the threats, such as eavesdropping, where unauthorized parties intercept voice communications, and denial of service (DoS) attacks, which can disrupt service availability.

Example Answer:

"To handle VoIP security concerns like eavesdropping, I implement encryption protocols such as Secure Real-time Transport Protocol (SRTP) to ensure that voice data is encrypted during transmission. Additionally, I use Transport Layer Security (TLS) to secure signaling data. For mitigating DoS attacks, I deploy firewalls and intrusion detection/prevention systems (IDS/IPS) to monitor and block malicious traffic. Regularly updating and patching the VoIP software and hardware is also crucial to protect against known vulnerabilities. Furthermore, I conduct regular security audits and vulnerability assessments to identify and address potential security gaps. By combining these strategies, I can effectively safeguard VoIP systems against common security threats."
