Enterprise UC Security


Enterprises leveraging Session Initiation Protocol (SIP) technology truly changes the way we think about communicaitons . With SIP, unified communication (UC) applications become just another “data application” and without appropriate security measures in place, networks could be opened to bad actors exposing the business, technology, privacy and compliance to broad new attack vectors.

Unfortunately, bad actors are constantly looking for new ways to infiltrate corporate networks, and when they do their attacks will become more brazen and targeted. Just because you have not experienced a SIP/UC security breach does not mean the communications network has not been compromised. Bad actors may well be monitoring the network without your knowledge and just waiting for the opportunity to exploit any vulnerabilies, enabling them to go about their business with impunity. Perhaps they have already penetrated and compromised your network - waiting for ‘the right time” to initiate their C2, (Command and Control) to exfiltrate data or to shut down communication access for your customers.

So what are some of the more concerning threats against unified communicaitons? Well, here are 4 to think about…

  • Denial of Service on UC Ports
  • Telephony Denial of Service (TDoS)
  • Theft of Service - Toll Fraud
  • Network Penetration - Opening Other Entry Points

So How Do You Secure Unified Communications?

It’s without question that the use of Session Border Controllers (SBCs) has grown exponentially in the past years.  SBCs are built to create a secure unified communications environment, where multiple devices across numerous networks interwork to create a unified user experience.

As organizations move to SIP for their UC sysems, the opportunity for "bank robbers" to access and steal services increases, unless an SBC is deployed.  Sonus provides SBCs and UC security technology.  With Sonus SBCs, enterprises can focus on their core competencies while service providers can provide extraordinary communications features to their customers.  Sonus can make sure both can do this without fear of theft on their networks.
