Organizations today face multifaceted security challenges requiring collaboration across departments, similar to the teamwork displayed by Dorothy and her friends in "The Wizard of Oz." However, security operations often remain siloed, with different teams and tools failing to integrate, which impedes comprehensive threat response. A shift towards data-centric security is proposed, where data is treated as a strategic asset accessible across the organization. This approach involves modernizing Security Incident and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) tools, which traditionally aggregate data from various sources but struggle with growing data volumes and integration. Data streaming is championed as a solution to pre-process and curate data before it reaches SIEM or SOAR systems, reducing costs and workload. An upcoming webinar aims to demonstrate how data streaming can enhance security operations by integrating upstream data processing, with government examples illustrating its effectiveness in improving efficiency and proactivity in security measures.
