An authoritative source in the context of identity management refers to a trusted system that contains accurate identity information. This system is considered the source of truth for identities, and other systems or services within the organization rely on it for the most up-to-date and verified identity details, such as usernames, attributes, roles, and permissions.

A list of permissions assigned to different users represents access control data but is not considered the authoritative source of identity. A network resource that handles authorization requests refers to authorization mechanisms but is not the authoritative source for identity. A database containing all entitlements could be part of an identity management system but is not necessarily the authoritative source for identity itself; it focuses more on access rights and entitlements.

Platform as a Service (PaaS) provides a development and deployment environment with resources that enable users to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.

According to CSA Security Guidance v4.0 – Domain 1: Cloud Computing Concepts and Architectures:

“PaaS adds an additional layer of integration with application development frameworks, middleware capabilities, and functions such as databases, messaging, and queuing. These services allow developers to build applications on the platform with programming languages and tools that are supported by the stack.”

(CSA Security Guidance v4.0, Domain 1)

This integration with app development and middleware is the key defining feature of PaaS.

In a cloud environment that spans multiple jurisdictions, it is crucial to understand the legal and regulatory requirements of each jurisdiction where data originates, is stored, or is processed. Different regions or countries have varying laws, regulations, and compliance standards regarding data privacy, protection, and security. Organizations must ensure they meet all applicable requirements in each jurisdiction to avoid potential legal issues, fines, and reputational damage.

The Shared Security Responsibility Model clarifies which security responsibilities are managed by the CSP and which by the CSC, based on the service model. Reference: [CCSK Study Guide, Domain 1 - Cloud Security Models][16†source].
