Event correlation type used when an organization operates across different operating systems and hardware platforms.

• A. Network-platform correlation
• B. Cross-platform correlation
• C. Same-platform correlation
• D. Multiple-platform correlation

Answer: (B)

Cross-platform event correlation focuses on analyzing and linking security events from different operating systems and hardware in a single view. In a heterogeneous environment, logs come from Windows, Linux, macOS, network devices, and more, each with its own formats and identifiers. Cross-platform correlation normalizes these data sources, aligns timestamps, and applies detection rules across platforms so that related actions—like a failed login on one system followed by unusual activity on another—are recognized as part of the same incident. This approach is essential when the organization operates across diverse environments, ensuring alerts reflect the full scope of activity rather than being siloed by platform.

Other terms imply narrowing to a single platform or mislabeling the breadth of data. Focusing on a single platform would miss cross-system relationships, while a term like multiple-platform correlation is less standard and can be confused with similar ideas. Cross-platform accurately captures the need to unify and correlate events across diverse operating systems and hardware.
