Physical layer monitoring ensures a holistic security posture. It adds an additional layer of security and insight into network traffic. Ransomware attacks often manifest as anomalies in the higher layers, but monitoring the physical layer can provide additional context and help detect potential threats.
Example: In the context of a data center, physical layer monitoring may include detecting physical cable tampering or hardwarebased attacks that could disrupt network connections. While ransomware detection primarily focuses on behavioral anomalies, physical layer monitoring can uncover underlying physical threats that may trigger these anomalies.
