Recent high-profile cyberattacks have many organizations understandably focusing their security efforts on preventing data breaches. While ensuring data security is indeed a top priority, enterprises must not become complacent in securing their mission-critical, real-time communications (RTC) applications, systems, and networks - including voice over IP (VoIP) and unified communications (UC) - which can be directly targeted as an attack objective in itself, or to exploit a new attack vector into other applications, systems, and networks, in order to effect a data breach.

This whitepaper consists of six short chapters that explore: 

  • Current trends in RTC, including the shift to session initiation protocol (SIP), enterprise mobility, and VoIP and UC
  • The modern security threat landscape, specifically denial of service (DoS) and telephony denial of service (TDoS), toll fraud, identity fraud, and new attack vectors exposed by RTC
  • How to secure RTC, including encrypting VoIP signaling and media, addressing specific security use case scenarios, understanding application reachability issues, and meeting regulatory compliance requirements
  • The differences between firewalls and session border controllers (SBCs)
  • Emerging trends in securing RTC
  • Key capabilities that an SBC brings to the fight in securing RTC
