In Prisma Cloud, the Resource Query Language (RQL) is used as a sophisticated querying language that enables deep inspection and analysis of cloud resources, configurations, and metadata. RQL is particularly adept at scanning Infrastructure as Code (IaC) templates because it allows for granular querying of cloud resources and their attributes, including those defined within IaC templates such as Terraform and CloudFormation. This capability is essential for identifying potential security risks, misconfigurations, and compliance issues within the infrastructure code before it's deployed, ensuring that cloud environments are secure from the outset.
