ISO 27001

ISO 27001 (formally known as ISO/IEC 27001:2005) is a specification for an information security management system (ISMS). An ISMS is a framework of policies and procedures that includes all legal, physical and technical controls involved in an organisation's information risk management processes.

ISO 27001 was developed to "provide a model for establishing, implementing, operating, monitoring, reviewing, maintaining and improving an information security management system."

ISO 27001 uses a top down, risk-based approach and is technology-neutral. The specification defines a six-step planning process:

1. Define a security policy.
2. Define the scope of the ISMS.
3. Conduct a risk assessment.
4. Manage identified risks.
5. Select control objectives and controls to be implemented.
6. Implementing Information Security Management System.

The specification includes details for documentation, management responsibility, internal audits, continual improvement, and corrective and preventive action. The standard requires cooperation among all sections of an organisation.

The 27001 standard does not mandate specific information security controls, but it provides a checklist of controls that should be considered in the accompanying code of practice, ISO/IEC 27002:2005.

ISO 27002

The ISO 27002 documents the comprehensive set of information security control objectives and a set of generally accepted security controls and good practices that can be audited against under ISO 27001.

ISO 27002 contains 12 main sections:

1. Risk assessment
2. Security policy
3. Organization of information security
4. Asset management
5. Human resources security
6. Physical and environmental security
7. Communications and operations management
8. Access control
9. Information systems acquisition, development and maintenance
10. Information security incident management
11. Business continuity management
12. Compliance
