1 Scope
The present document summarizes and analyses existing and potential mitigation against threats for AI-based systems
as discussed in ETSI GR SAI 004 [i.1]. The goal is to have a technical survey for mitigating against threats introduced
by adopting AI into systems. The technical survey shed light on available methods of securing AI-based systems by
mitigating against known or potential security threats. It also addresses security capabilities, challenges, and limitations
when adopting mitigation for AI-based systems in certain potential use cases.
