CSIAC Webinars – STIR SHAKE’N SIP to Stop Robocalling



Americans lost almost a billion dollars to fraud in 2017 with the preferred method for scammers being over the phone. The Internal Revenue Service (IRS) has maintained phone scams on their Annual “Dirty Dozen” list of top tax scams in 2018. Further, the average individual received 14.4 robocalls in May 2019 alone, that’s a whopping 4.7 billion robocalls in one month. This is an unprecedented high, well surpassing levels of dinner time nuisance into domains that seriously erode the value and trust in voice service and debilitates the infrastructure. The telephony industry across all access methods is worth several hundreds of billions of dollars and work continues in the industry to safeguard and secure voice services against cybercriminals.

In this webinar Daksha Bhasker would like to bring the attention of the cybersecurity community to the STIR/Shaken (Secure Telephony Identity Revisited/Signature-based handling of Asserted Information using tokens) framework that has been socialized by the robocall strike-force comprising of members across the telecommunications ecosystem in North America in partnership with several councils, forums, Standards bodies and organizations such as the IETF, ATIS, SIP Forum and 3GPP.

In this webinar Daksha Bhasker will provide an overview of the problem at hand, walk through the STIR/SHAKEN architecture, its components, and discuss security architecture considerations that will bolster the implementation. As international regulatory bodies move towards driving security measures against robocalling, this webinar will enable security professionals partner with voice engineering and operations teams where implementation maybe upcoming, be able to partner and support work underway by their telephony providers and be able to ask their suppliers and vendors pertinent security questions that will enable secure architectures and implementation of STIR/SHAKEN.
