International Effort with Collaboration Between Cloud Security Alliance and Huawei Culminated in International Standard ISO/IEC 21878

Singapore – November 26, 2018The Cloud Security Alliance (CSA), the world’s leading organization dedicated to defining and raising awareness of best practices to help ensure a secure cloud computing environment, is pleased to announce that the international standard ISO/IEC 21878 – Security Guidelines for Design and Implementation of Virtualized Servers has been published as of November 2018 .

The purpose of this document is to provide security guidelines for the design and implementation of virtual servers (VSs). Design considerations focusing on identifying and mitigating risks, and implementation recommendations with respect to typical VSs are covered in this document.

“This publication of ISO/IEC 21878 reinforces Singapore as one of the leading countries in Asia Pacific on the cutting edge of developing best practices for the cloud ecosystem. CSA APAC will continue to work closely with APAC countries to demonstrate standardization and technical expertise at the international level.” said Dr. Hing-Yan Lee, Executive Vice President for Asia Pacific, CSA.

This was a result of a joint project formalized in June 2013 between CSA and SPRING Singapore (now Enterprise Singapore) to integrate Singapore’s TR 30 : 2012 – Virtualization Security for Servers and CSA’s Cloud Controls Matrix into a CSA whitepaper. The whitepaper titled ‘Best Practices for Mitigating Risks in Virtualized Environment’ was published in April 2015, and was subsequently submitted in the same year as an input document to ISO to help steer international standardization efforts.

In November 2018, ISO approved the publication of the effort as ISO21878 “Security Guidelines for Design and Implementation of Virtualized Servers”. The Co-Editors of this international effort include Mr Xiaoyu Ge, IT Security and Cloud Services Standards Director from Huawei as CSA’s representative. Further information can be found here and here.

The intended goal of this document is to facilitate informed decisions with respect to architecting VS configurations. Such design and implementation configuration is expected to assure the appropriate protection for all virtual machines (VMs) and the application workloads running in them in the entire virtualized infrastructure of the organization.

Data center infrastructures are rapidly becoming virtualized due to increasing deployment of VSs for cloud computing services and for internal IT services. Since VSs are compute engines hosting many business-critical applications, they are key resources to be protected in virtualized data center infrastructure. As VSs are becoming mainstream in typical data center infrastructure setups, the secure design and implementation of VSs forms an important element in the overall security strategy.

The motivation for this document is the global trend in enterprises and government agencies deploying server virtualization technologies within their internal IT infrastructure as well as the use of VSs by cloud service providers. Hence the target audience is any organization using and/or providing VSs.

“IT Security is always an important consideration for customers and the industry. Huawei has been involved in CSA and ISO/IEC JTC1 SC27 standardization activities for a long time, and we look forward to continuing work with CSA and other standards organizations for a better and more secure IT industry” said Yolanda You, Senior Standards Director, Huawei IT Product Line. The scope of this document specifies security guideline for the design and implementation of VSs.This document is not applicable to Desktop, OS, network, and storage virtualization, and vendor attestation.It will benefit any organization using and/or providing VSs.
