What is ISO/IEC 27017:2015-Information technology?
ISO/IEC 27017:2015-Information technology focuses on information security controls for cloud services. The full title of the standard is “ISO/IEC 27017:2015 – Information technology – Security techniques – Code of practice for information security controls based on ISO/IEC 27002 for cloud services.”
ISO 27017 provides guidance and best practices for both cloud service providers and cloud service customers to ensure the security of information in the cloud environment. It is an extension of the ISO/IEC 27002 standard, which is a widely recognized framework for establishing, implementing, maintaining, and continually improving an information security management system (ISMS).
The standard addresses specific security issues that are relevant to cloud computing. It covers a range of topics, including:
- Information security policies and procedures for cloud-based services.
- Roles and responsibilities of cloud service providers and customers.
- Protection of information assets in the cloud, including confidentiality, integrity, and availability.
- Access control mechanisms for cloud services.
- Incident management and response in the cloud environment.
- Compliance with legal and regulatory requirements.
- Continuity and disaster recovery planning for cloud-based services.
- Monitoring and auditing of cloud service providers.
Therefore, organizations can enhance the security of their cloud services, mitigate risks, and demonstrate their commitment to protecting sensitive information stored and processed in the cloud as this standard helps promote trust, transparency, and confidence in cloud-based solutions.
