OpenC2 Presentation at SecOps24.

TC member Vasileios Mavroeidis will be presenting on OpenC2 at the SecOps2024 International Exercise & Conference on Security Operations. This event takes place February 15, 2024 in Budapest, Hungary.

Title: Do away with siloed cybersecurity operations and customized integrations.

Description: As the number of vulnerable channels continues to grow, there is also an increase in the deployment of security solutions. This highlights the importance of interconnecting an organization’s cybersecurity solutions to ensure ongoing and effective threat management. However, integrations are costly to develop and maintain and heavily rely on proprietary communication interfaces that require reconfiguring parts or the entire defense ecosystem of the organization when tools are introduced or replaced or when there are updates to the APIs utilized. This presentation will discuss OASIS Open Command and Control (OpenC2), a standardized machine-to-machine language for the command and control of cyber defense technologies, allowing them to interoperate without needing customized integrations.
