Cloud security has become increasingly complex due to the proliferation of APIs, container orchestration systems, and cloud-native platforms, shifting more security responsibility to customers. Dan Hubbard, CEO of Lacework, introduced the "Shared Irresponsibility Model" at PagerDuty's virtual Summit, emphasizing the importance of collaboration between DevOps and security teams to avoid blame and enhance security practices. He outlined four key factors affecting cloud security: alignment of architecture and infrastructure, shared tooling and data sources, real-time data change management, and automated workflows. Hubbard highlighted the need for cohesive efforts to manage security risks and improve operational efficiency, and noted the integration partnership between Lacework and PagerDuty, which facilitates better incident response by ensuring relevant information is directed to the appropriate team members.
