What is the ISO 27002 standard?
What is the difference between ISO 27002 and ISO 27001?
ISO 27001 provides the specification for an ISMS, including requirements for the risk management process that you should use to choose the security measures appropriate to the risks your organization faces.
ISO 27002 serves as a guidance document, providing best-practice guidance on applying the controls listed in Annex A of ISO 27001. It supports, and should be read alongside, ISO 27001.
ISO 27001 is the only information security Standard against which organizations can achieve independently audited certification.
This provides independent, expert assurance that information security is managed in line with international best practice.
How to select and implement ISO 27001 security controls
Security controls are an important part of information security management for all organizations that store and manage confidential information.
Although the specific requirements for handling information security will vary from organization to organization, there are many common controls that organizations can implement to secure their data and meet their legal and contractual obligations.
Clause 6.1.2 of ISO 27001 sets out a risk management process that organizations should follow when selecting and implementing security controls.
It states that the risk assessment process must:
- Establish and maintain certain information security risk criteria
- Ensure that repeated risk assessments “produce consistent, valid and comparable results”
- “identify risks associated with the loss of confidentiality, integrity and availability for information within the scope of the information security management system”
- Identify the owners of those risks
- Analyze and evaluate information security risks according to certain criteria
- Be documented

What are the ISO 27001/ISO 27002 controls?
Annex A of ISO 27001 lists 114 security controls divided into 14 control sets, each of which is expanded upon in Clauses 5–18 of ISO 27002:
A.5 Information security policies
Information security should be directed from the top of the organization and policies should be communicated clearly to all employees.
A.6. Organization of information security
A management framework should support the organization’s information security operations, both on- and off-site.
A.7 Human resource security
Employees and contractors should be aware of their role in safeguarding the organization’s information both before and during employment. The organization’s information should also be protected.
A.8 Asset management
Organizations should identify their physical and information assets and determine the appropriate level of protection necessary for each.
A.9 Access control
Access to information and information processing facilities should be limited to prevent unauthorized user access. Users should be responsible for safeguarding their authentication information, such as passwords.
Policies on cryptography and the use of cryptographic keys should be developed and implemented to protect the confidentiality, integrity, and/or availability of information.
A.11 Physical and environmental security
Controls should be introduced to prevent unauthorized physical access, damage, and interference to information processing facilities.
A.12 Operations security
Information and information processing facilities should be protected from malware, data loss, and the exploitation of technical vulnerabilities.
A.13 Communications security
Information should be protected in networks and as it is transferred, both within the organization and externally.
A.14 System acquisition, development and maintenance
Information security should be designed and implemented throughout information systems’ lifecycle. Test data should also be protected.
A.15 Supplier relationships
Any of the organization’s information assets that are accessible by suppliers should be appropriately protected.
A.16 Information security incident management
Information security incidents should be handled consistently and effectively.
A.17 Information security aspects of business continuity management
