What is the role of shared responsibility models in cloud-based TPRM?

Shared responsibility models in cloud-based Third-Party Risk Management (TPRM) help to clearly define the responsibilities and accountability between vendors and organizations when it comes to managing risks associated with third-party relationships. These models outline which party is responsible for different aspects of security and compliance in a cloud environment.

Shared responsibility typically divides responsibilities into two main categories:

1. Provider Responsibility: Cloud service providers are responsible for the security of the cloud infrastructure itself, such as physical data centers, networking infrastructure, and the hypervisor layer. They are also responsible for ensuring the availability and integrity of their services.

2. Customer Responsibility: Customers using cloud services are typically responsible for securing their data, applications, operating systems, and configurations within the cloud environment. They must also manage user access, encryption, and compliance with regulations relevant to their industry.

By clearly delineating these responsibilities, shared responsibility models help both parties understand their role in securing data and systems within the cloud environment. This clarity helps to avoid misunderstandings, gaps in security coverage, and potential compliance issues that could arise from unclear accountabilities.

Overall, shared responsibility models enhance collaboration between vendors and organizations, promote a more secure cloud environment, and mitigate risks associated with third-party relationships in TPRM.
