Cloud Service Customer

According to the international standard ISO/IEC 27017, a Cloud Service Customer (CSC) is the "party which is in a business relationship for the purpose of using cloud services." In simple terms, it's any company or individual that purchases and utilizes cloud services from vendors like Amazon Web Services (AWS), Google Cloud, or Microsoft Azure.

If companies mismanage cloud-related risks, they can face leakage of trade secrets or personal data, leading to violations of local regulations like Taiwan's Personal Data Protection Act (PDPA), resulting in hefty fines and lawsuits. Furthermore, many international supply chains (e.g., automotive, semiconductor) and financial regulators require their partners to meet specific cybersecurity standards, risking loss of business or regulatory action for non-compliance.

Directly related standards include: - **ISO/IEC 27017**: A code of practice for information security controls for cloud services, which explicitly clarifies the respective responsibilities of the customer (CSC) and the provider (CSP). - **ISO/IEC 27001**: The foundational framework for an Information Security Management System (ISMS), with Annex A control 5.23 specifically addressing the acquisition, use, management of, and exit from cloud services. - **ISO/IEC 27018**: A code of practice for protecting Personally Identifiable Information (PII) in public clouds. - **GDPR**: The EU's General Data Protection Regulation is applicable if the business involves residents of the European Union.
