Electromagnetic Side-Channel Analysis (EM-SCA) has been demonstrated as a viable technique for extracting forensic insights from Internet of Things (IoT) devices. However, the complexity of the data acquisition and analysis processes demands a high level of technical expertise from forensic investigators, which poses practical challenges in real-world scenarios. To address these challenges, this research proposes a Forensics-as-a-Service (FaaS) platform aimed at mitigating technical barriers by streamlining the EM-SCA process. This research introduces EMvidence, a FaaS platform designed to simplify and automate Electromagnetic (EM) data acquisition, handling, and analysis in IoT forensic investigations. The platform comprises two components: the EMvidence data acquiring application for efficient data capture at crime scenes, and the EMvidence web application for cloud-based analysis of EM data. Comprehensive evaluations were conducted on key aspects, including data acquisition, file transfer, pre-processing, and analysis, to assess the platform's effectiveness in supporting forensic investigations.
