ISO 27017
Overview

5. Locking Up Your Cloud Environment | 5
• Based on ISO/IEC 27002 for cloud providers
• December 15, 2015
• Applicable to the provision and use of cloud services
• Supplement to ISO 27002 for cloud providers
ISO 27017 Overview

6. Locking Up Your Cloud Environment | 6
• Alignment to ISO 27001 Annex A / ISO 27002
• Cloud server provider control guidance
• Not intended to be a unique control set
– e.g. A6.1.2 – segregation of duties
• Recommendations not Requirements
– Should v Shall
27017 Design

7. Locking Up Your Cloud Environment | 7
• 35 supplemental controls to ISO 27001 Annex A
– All domains but Information Security Aspects of
Business Continuity
– A5 (1), A6 (2), A7 (1), A8 (2), A9 (7), A10 (2), A11 (1),
A12 (6),
A13 (1), A14 (2), A15 (2), A16 (3), A18 (5)
27017 Depth – Supplemental Controls

8. Locking Up Your Cloud Environment | 8
• 7 extended controls (27017 Annex A)
– Covers domains A6, A8, A9, A12, and A13
– Act as additional control to complement that of
Annex A
27017 Depth – Extended Controls

9. Locking Up Your Cloud Environment | 9
27017 – How Unique?
• Not very unique
• Most CSPs are already designed to meet 27017
• Supplemental Control Example
• Extended control

10. Locking Up Your Cloud Environment | 10
ISO 27018
Overview

11. Locking Up Your Cloud Environment | 11
• Code of practice for protection of personally identifiable
information (PII) in public clouds acting as PII processors
• Issued August 1, 2014
• Commonly accepted control objectives, controls and
guidelines for implementing measures to protect PII in
accordance with the privacy principles in ISO/IEC 29100
for the public cloud computing environment.
• Supplement to ISO 27002 for public cloud providers
ISO 27018 Overview

12. Locking Up Your Cloud Environment | 12
• Alignment to ISO 27001 Annex A / ISO 27002
• Public cloud PII protection control implementation
guidance
• Not intended to be a unique control set
– e.g. A6.1.2 – segregation of duties
• Recommendations not Requirements
– Should v Shall
27018 Design

13. Locking Up Your Cloud Environment | 13
• 14 supplemental controls to ISO 27001 Annex A
– All domains but Asset Management; System
Acquisition, Development, and Maintenance; Supplier
Relationships; and Information Security Aspects of
Business Continuity Management
– A5 (1), A6 (1), A7 (1), A9 (2), A10 (1), A11 (1), A12 (4),
A13 (1), A16 (1), A18 (1)
27018 Depth – Supplemental Controls

14. Locking Up Your Cloud Environment | 14
• 25 extended controls (based on 11 privacy principles of
ISO/IEC 29100)
– Covers:
• Consent and Choice; Purpose legitimacy and specification;
Data minimization; Use, retention and disclosure limitation;
Openness, transparency and notice; Accountability;
Information security; and Privacy compliance
– Act as additional control to complement
that of Annex A
27017 Depth – Extended Controls

15. Locking Up Your Cloud Environment | 15
• More unique than 27017
• Incorporation of privacy principles
• Supplemental Control Example
– A11.2.7– Secure disposal or re-use of equipment
– Equipment containing storage media that may possibly contain PII should be
treated as though it does
• Extended control
– A.4 – Data Minimization
– Temporary files and documents should be erased or destroyed within a
specified, documented period
