ISO 27001 in Canada (Information security management system – ISMS)

ISO/IEC 27001 is widely known, providing requirements for an information security management system (ISMS), though there are more than a dozen standards in the ISO/IEC 27000 family. Us

ing them enables organizations of any kind to manage the security of assets such as financial information, intellectual property, employee details, or information entrusted by third parties.

An effective ISO 27001 information security management system (ISMS) provides a management framework of policies and procedures that will keep your information secure

Top tips for implementing ISO 27001 (ISMS)

1. Engage the whole business with good internal communication.
2. Compare existing information security management with ISO 27001 requirements.
3. Get customer and supplier feedback on current information security.
4. Establish an implementation team to get the best results.
5. Map out and share roles, responsibilities, and timescales.
6. Adapt the basic principles of the ISO 27001 standard to your business.
7. Motivate staff involvement with training and incentives.
8. Share ISO 27001 knowledge and encourage staff to train as internal auditors.

ISO 27001 helps organizations to treat data security seriously, putting in systems and processes to guard against the risk of security breaches or misuse of data. It works with your business and the kind of data it holds, whether that is bank account details, staff records, passwords, or client confidential information.

ISO 27001 (ISMS) certification shows that a business has:

• Protected information from getting into unauthorized hands
• Identifying and treating business risks
• Ensured information is accurate and can only be modified by authorized users
• Assessed the risks and mitigated the impact of a breach
• Building internal awareness of your information security program
• Been independently assessed to an international standard based on industry best practices
• Aligning information security with your overall business objectives

The official name of ISO/IEC 27017 is the Code of practice for information security controls based on ISO/IEC 27002 for cloud services, which means this standard is built upon the existing security controls of ISO 27002.

ISO 27017 Information security controls for cloud services suggests seven controls:

• Shared roles and responsibilities within a cloud computing environment
• Removal of cloud service customer assets
• Segregation in virtual computing environments
• Virtual machine hardening
• Administrator’s operational security
• Monitoring of cloud services
• Alignment of security management for virtual and physical networks

ISO/IEC 27018 (Information technology — Security techniques — Code of practice for protection of personally identifiable information (PII) in public clouds acting as PII processors) is the first International Standard that focuses on the protection of personal data in the cloud. Although only a few months old, the new standard should finally give cloud users confidence that their service provider is well-placed to keep data private and secure.

ISO 27018 specifically addresses the requirements of data protection law. The focus here is mainly on the processing of personal data within the cloud.

Certification is based on ISO 27001 supplemented by the applicable standard.

ISO 27018 lists the following additional controls in order to increase the level of protection of personal data in the cloud:

• Rights of the customer to access and delete the data
• Processing the data only for the purpose for which the customer has provided this data
• Not using the data for marketing and advertising
• Deletion of temporary files
• Notification to the customer in case of a request for data disclosure
• Recording all the disclosures of personal data
• Disclosing the information about all the sub-contractors used for processing the personal data
• Notification to the customer in case of a data breach
• Document management for cloud policies and procedures
• Policy for return, transfer and disposal of personal data
• Confidentiality agreements for individuals who can access personal data
• Restriction of printing the personal data
• Procedure for data restoration
• Authorization for taking the physical media off-site
• Restriction of usage of media that does not have encryption capability
• Encrypting data that is transmitted over public networks
• Destruction of printed media with personal data
• Usage of unique IDs for cloud customers
• Records of user access to the cloud
• Disabling the usage of expired user IDs
• Specifying the minimum security controls in contracts with customers and subcontractors
• Deletion of data in storage assigned to other customers
• Disclosing to the cloud customer in which countries will the data be stored
• Ensuring the data reaches the destination

ISO 27017 and ISO 27018, both based on ISO 27001, have been specially adapted to the specific requirements of cloud service providers. ISO 27017 is primarily concerned with the relationship between providers and their customers. As part of the ISO 27017 audit, our experts help you identify key security elements that improve the quality and reliability of your cloud services.

Which one to go for – ISO 27001, ISO 27017, or ISO 27018?

ISO 27001 is a perfect basic standard for all companies that want to protect their information, it provides the framework for managing security.

ISO 27017 is certainly appealing to companies that offer services in the cloud, and want to cover all the angles when it comes to security in cloud computing. On the other hand, ISO 27018 is more focused on companies that handle personal data, and want to make sure they protect this data.

So for cloud companies, you will often see a combination of ISO 27001 and ISO 27017 implementation, and cloud companies with lots of personal data will probably go for all three: ISO 27001, ISO 27017, and ISO 27018.
