Security Governance for Enterprise VoIP Communication

Voice is, besides email, the major personal communication technology for businesses. As it is often used for sensitive conversations, an appropriate security level is of great relevance. Historically, security measures have either been targeted to prevent fraud, thereby securing the operatorpsilas business model, or to provide military-class end-to-end encryption. Neither approach targets the security objectives of enterprises using private and public voice communication for sensitive business exchanges. A graded approach to VoIP security for enterprise communication allows for a step-wise introduction of security features required for voice communication of different security levels similar to common data protection classes.
