Has your organization documented the conditions under which shared responsibility models with third parties are acceptable for cybersecurity functions, financial transactions, and cloud services?

Shared responsibility models define which security controls are managed by your organization versus those managed by vendors or partners. Clear documentation helps prevent security gaps where each party assumes the other is responsible for a particular control. This is especially important for outsourced cybersecurity functions, financial transaction processing, and cloud service usage where responsibilities often overlap. Evidence could include a formal document outlining shared responsibility acceptance criteria, vendor management policies that define security requirements for different types of third-party relationships, or cloud service provider agreements with clearly marked security responsibility matrices.
