Shared-responsibility model

As explained in Data-Driven Cybersecurity

Shared responsibility is an operating pattern in which a cloud provider secures the underlying infrastructure while the customer secures its data and workloads.

In a cloud environment, the provider secures the underlying infrastructure while the customer secures its data and workloads. This division changes where an organization must direct its own security effort: using a cloud service does not remove the need to check customer-controlled configurations. section 10.5.1

Turn that division into operational checks:

  • Check cloud storage permissions, encryption policies, IAM roles, and security groups for insecure configurations. section 10.5.1
  • Detect newly deployed workloads that may be misconfigured or compromised, even when workloads are created and removed rapidly. section 10.5.1
  • Give teams clear security ownership, shared metrics, and role-relevant training so responsibilities are carried out consistently. section 5.2 section 7.2

A newly deployed workload

A company deploys a cloud workload and checks whether its storage permissions and IAM roles meet policy. AWS Config or Azure Policy can help assess those configurations. The practical question is not whether the provider secures its infrastructure, but whether the company has secured the settings and workload it controls. section 10.5.1

How Data-Driven Cybersecurity covers it

How deep it goes
Defines the provider–customer division and identifies configuration checks, but does not give a step-by-step implementation procedure.
Examples
Uses storage-bucket permissions, encryption policies, IAM roles, security groups, and newly deployed workloads as concrete security concerns.
What it assumes
Defines the responsibility split directly while leaving cloud workloads, storage permissions, and IAM roles otherwise unexplained.
What you can do after
Apply it via AWS Config or Azure Policy to check whether customer-controlled cloud configurations adhere to security policies.
How it connects
Links the model to cloud threat detection, IAM roles, security groups, security policies, and organizational security ownership.
