ISO 27001 Information Security Management System

ISO 27001 is a systematic approach (Plan-Do-Check- Act) for managing companies’ information security to achieve business objectives.

It is based on a risk assessment and the companies’ risk defined levels designed to effectively treat and manage risks.

Considering requirements for the protection of information assets and implementing suitable control measures to ensure the protection of these information assets, as required, contributes to the successful implementation of an ISMS.

ISO 27001 information security management system can help your company to better manage your information assets and implement controls to help protect your companies’ information assets from an information security breach.

When implementing ISO 27001 ISMS, your company is required to establish documentation (policies, procedures, guidelines), and allocate associated resources and arrange activities for protecting its information assets.

ISO 27017 cloud-specific information security controls

ISO/IEC 27017 helps company to manage the different security risks and ensure the appropriate cloud security controls are in place so you can maintain a resilient ISMS.
The major points :
6.3.1 Shared roles and responsibilities within a cloud computing environment
8.1.5 Removal of cloud service customer assets
9.5.1 Segregation in virtual computing environments
9.5.2 Virtual machine hardening
12.1.5 Administrator’s operational security
12.4.5 Monitoring of cloud services
13.1.4 Alignment of security management for virtual and physical networks
So, there’s nothing spectacular here – mostly common sense when speaking about cloud security.
