An information security analyst at Aurora Systems is reviewing a confidentiality model where users cannot read information above their clearance and they cannot write information to a lower…

Role based access control (RBAC) grants permissions based on a user's role within an organization, not directly on sensitivity labels or clearance levels with strict no-read-up/no-write-down rules.

Cloud Identity and Access Management (IAM) is a broad category of services and not a specific access control model that inherently enforces the Bell-LaPadula model's no-read-up/no-write-down rules.

Mandatory Access Control (MAC) enforces security policies by assigning security labels to subjects (users) and objects (data), preventing users from reading information with a higher sensitivity label (no read-up) and from writing information to an object with a lower sensitivity label (no write-down), embodying the Bell-LaPadula model for confidentiality. This strict enforcement is managed by the system administrator, not the owner of the resource.

Attribute based access control (ABAC) grants permissions based on attributes of the user, resource, and environment, offering fine-grained control but not inherently enforcing the strict read/write rules of a confidentiality model like Bell-LaPadula.
