📖 What is ISO/IEC 27017?
ISO/IEC 27017 is an international standard that provides guidelines for information security controls applicable to the provision and use of cloud services. It extends the ISO/IEC 27002 controls to specifically address cloud-specific risks.
"Remember that 27017 is about how to implement cloud security controls, whereas 27018 focuses specifically on privacy and PII in the cloud."
📚 Certification: CCSP (CCSP)
🔑 What are the Key Concepts of ISO/IEC 27017?
- ▸ Extension of ISO/IEC 27002: It does not replace 27002 but adds cloud-specific guidance to existing security controls to address unique cloud risks.
- ▸ Shared Responsibility Model: Emphasizes the critical need for clear delineation of security roles and obligations between the Cloud Service Provider and the Cloud Service Customer.
- ▸ CSP-Specific Controls: Provides guidelines for providers on implementing security measures to protect the underlying cloud infrastructure and isolate tenant data effectively.
- ▸ CSC-Specific Controls: Offers guidance for customers on how to configure and manage security settings within the cloud environment to ensure data protection.
- ▸ Risk-Based Approach: Focuses on identifying cloud-specific threats, such as multi-tenancy risks and API vulnerabilities, to apply the most effective security controls.
🎯 How does ISO/IEC 27017 appear on the CCSP Exam?
You may be asked to identify the appropriate international standard when a company wants to implement a security management system specifically tailored for cloud environments by extending ISO 27002.
A scenario might describe a dispute between a provider and a customer regarding security obligations; expect questions on how ISO 27017 helps define these shared responsibilities.
Expect questions where you must distinguish between a standard focused on general cloud security controls (27017) versus one focused strictly on PII protection in the cloud (27018).
❓ Frequently Asked Questions
Does a company need ISO 27001 certification before adopting ISO 27017?
While ISO 27017 provides the cloud-specific controls, it is designed to work within the framework of ISO 27001. Most organizations use 27017 to enhance their existing ISO 27001 Information Security Management System (ISMS) for cloud operations.
What is the primary difference between ISO 27017 and ISO 27018?
ISO 27017 is a broad security standard covering various cloud controls and risks. In contrast, ISO 27018 is a specialized code of practice focused exclusively on the protection of Personally Identifiable Information (PII) in public clouds.
