Develop a set of security protocols for protecting your organization’s VoIP infrastructure. Consider potential threats such as [Eavesdropping], [Denial of Service Attacks], and [Fraudulent Call Routing]. Create a risk assessment that includes current vulnerabilities and mitigation strategies, such as end-to-end encryption, firewalls, and regular security audits. Additionally, outline training for employees on security best practices related to VoIP systems, and specify the necessary compliance standards for the system to meet, such as [GDPR] or [HIPAA].
