Exploring the Path to Authenticated Communication: Understanding Attestation Levels

August 17 @ 16:00 - 17:00 BST

Join us for an engaging webinar as we delve into the intricacies of call authentication, specifically the Consolidated Signing Service Provider (SSP) Matrix of Attestation found in Appendix A of the 2020 CATA (Call Authentication Trust Anchor) Working Group’s report, “Best Practices for the Implementation of Call Authentication Frameworks.” Attestation levels play a crucial role in verifying the legitimacy of caller identity, and this webinar aims to provide a comprehensive understanding of attestation and its implications.

Our expert panel of hosts will explore the factors that contribute to the appropriate assignment of attestation levels: A (full), B (partial), or C (gateway). We will analyze the significance of each factor and its impact on attestation, while also addressing the challenges faced by Consolidated Signing Service Providers (SSPs) when determining attestation levels. This includes considerations such as connectivity limitations and indirect connections between service providers and call originators.

Through thought-provoking discussions and practical examples, we will shed light on the nuances of call authentication and its relationship to the Consolidated Signing Service Provider (SSP) Matrix of Attestation.

Whether you are a telecommunications professional, a call authentication enthusiast, or a policymaker, this webinar offers valuable insights into the complexities of attestation and a deep dive into “Best Practices for the Implementation of Call Authentication Frameworks” and its implications for ensuring trust and security in call authentication.
