Securing Real-Time Communications

Service providers manage billions of minutes of SIP-based real-time communications (RTC) traffic on their networks, at peering points with other operators, and across much of their access networks. Session border controllers (SBCs) serve a critical role in securing RTC by being deployed at access or interconnect points to protect the network from malicious threats, such as Distributed Denial of Service (DDoS) attacks, as well as performing important call management, media processing, and interworking functions.

In addition to deploying appliance-based SBCs, many service providers are also now deploying SBCs on their own private cloud, or even on public clouds. In these virtual, cloud-based deployment models, the expectations for SBC reliability and functionality remain the same as if they were appliance-based. By integrating Ribbon SBCs into their network, service providers will efficiently and effectively protect, secure, simplify, and standardize real-time, SIP-based multimedia communications.

In addition to deploying SBCs, it is possible to use analytics to mitigate bad actor infiltration, identify and deny rogue endpoints, prevent robocalls, stop Telephony DoS (TDoS) attacks and eliminate network incursions using SIP.  Completely protecting real-time communications starts with a deep understanding of attack vectors targeting SIP. Ribbon, a leader in SIP security and session border controller technologies, has the solutions capable of identifying and mitigating specific threats targeting SIP-based real-time communications.

Securing Real-Time Communications Features & Benefits

  • Complete security for signaling and media, including traffic policing, Denial of Service (DoS) and Distributed Denial of Service (DDoS) attack detection and blocking and rogue Real-Time Transport Protocol (RTP) protection.
  • Ensure privacy on the media (SRTP) and signaling (IPSec/TLS) path without sacrificing scalability or performance.
  • By invoking “Back-to-back user agent (B2BUA) functionality the SBC can hide the underlying network addresses from bad actors attempting to infiltrate and steal mission-critical data.
  • In the event of an equipment failure, physical attack or persistent DoS/DDoS attack, Ribbon's redundant architecture maintains service, with geo-redundancy options for disaster recovery.
  • Integration with Ribbon Analytics as as a "detector" of malicious attacks or as an "enforcer" of security policies.
