Community Cloud

A community cloud is a cloud infrastructure provisioned for exclusive use by a specific community of organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). As defined by the U.S. National Institute of Standards and Technology (NIST) in SP 800-145, it may be owned, managed, and operated by one or more of the organizations in the community, a third party, or a combination thereof, and it may exist on or off premises.

For industries with tight supply chains like semiconductors, finance, and healthcare, community clouds facilitate collaboration but also introduce risks. Since multiple organizations share resources, a security breach in one member can expose the entire community's sensitive data (e.g., trade secrets, personal data), creating a supply chain vulnerability. This could violate obligations under Taiwan's Personal Data Protection Act and the Cyber Security Management Act, leading to business interruption, reputational damage, significant claims, and regulatory fines, impacting corporate sustainability.

Standards directly related to community clouds include: 1. **ISO/IEC 27001**: The overall framework for an Information Security Management System (ISMS), fundamental to all security management. 2. **ISO/IEC 27017**: A code of practice for information security controls for cloud services. It provides specific guidance for multi-tenant environments like community clouds on aspects such as virtual environment segregation and responsibility sharing (e.g., controls CLD.6.3.1, CLD.9.5.1). 3. **ISO/IEC 27018**: A code of practice for protecting Personally Identifiable Information (PII) in public clouds, crucial when the community cloud processes personal data.
