AI-Assisted Security Controls Mapping for Clouds Built for Regulated Workloads

Abstract

Data privacy, security and compliance concerns prevent many enterprises from migrating their critical applications to public cloud infrastructure. To address this, cloud providers offer specialized clouds for heavily regulated industries, which implement prescribed security standards. A critical step in the migration process is to ensure that the customer’s security requirements are fully met by the cloud provider. With a few hundreds of services in a typical cloud provider’s infrastructure, this becomes a non-trivial task. Few tens to hundreds of security checks exposed by each applicable service need to be matched with several hundreds to thousands of security controls from the customer. Mapping customer’s controls to cloud provider’s control set is done manually by experts, a process that often takes months to complete, and needs to be repeated with every new customer. Moreover, these mappings have to be reevaluated following regulatory or business changes, as well as cloud infrastructure upgrades. We present an AI-assisted system for mapping security controls, which drastically reduces the number of candidates a human expert needs to consider, allowing substantial speed-up of the mapping process. We empirically compare several controls mapping models, and show that hierarchical classification using fine-tuned Transformer networks works best. Overall, our empirical results demonstrate that the system performs well on real-world data.
