To configure serverless scanning in a cloud security platform like Prisma Cloud, the system needs to know where (Region) the serverless functions are deployed, how to access them (Credential), and on which cloud platform they are running (Provider). These settings ensure that the scanning tool can accurately locate and authenticate to the serverless functions across different cloud environments for vulnerability assessment. This aligns with the principle of providing comprehensive visibility and consistent security across multi-cloud environments as outlined in the 'Guide to Cloud Security Posture Management Tools' document.

The audit trail section of an asset's detail view in Prisma Cloud typically includes a log of configuration changes and alert and vulnerability events associated with the asset. These elements are crucial for tracking the history of modifications to an asset's configuration and the security incidents that have affected it. This information is instrumental in understanding the security posture of the asset over time and in conducting thorough investigations after a security event has been detected.

Regarding the use of access keys, it is correct that up to two access keys can be active at any time for a single IAM user in AWS, and access keys are used for programmatic API calls to AWS services. This allows for rotation of keys without immediate invalidation of the old key and ensures secure access to AWS services via APIs.
