Introduction to ISO IEC 27001 Information Security Management
The rising value of information to organizations combined with recent high profile information security breaches are highlighting the ever mounting requirement for organizations to protect their information. In order to ensure the continuity of your operations and the safety of your data and systems, the security of information systems and critical business information must be constantly and actively managed.
Unprotected systems are vulnerable to many threats, including computer-assisted fraud, sabotage, and viruses. These threats can be internal or external, accidental or malicious. Breaches in information security can allow vital information to be accessed, stolen, corrupted or lost. It is crucial that every company institutes appropriate controls and procedures in place to avoid such incidents.
The internationally recognized information security management system ISO 27001 (known as ISO/IEC 27001) is suitable for any organization, large or small, in any sector or part of the world where managing sensitive company information and keeping it secure from outsiders is important. The standard is particularly suitable where the protection of information is critical, such as in the finance, health, public and IT sectors.
The 2013 standard puts more emphasis on measuring and evaluating how well an organization’s ISMS is performing and there is a new section on outsourcing, which reflects the fact that many organizations rely on third parties to provide some aspects of IT. More focus is on the organizational context of information security and risk assessment has changed. Overall, 27001:2013 is designed to fit better alongside other management standards such as ISO 9001, ISO 14001 and ISO/IEC 20000 and the structure has more in common with other standards.
The IT department is the main focus of ISO 27001 implementation, but the standard involves areas in the entire company as well. The main driver, sponsor, and promoter of the change must be the company’s management, while its IT is mainly responsible for its execution. In addition to management and IT, the departments that must be involved include HR, Training and Education, Building Security, Building Maintenance, Legal Department as well as suppliers, outsourcing and, last but not least, employees.
ISO 27001 is also highly effective for organizations that manage information on behalf of others, such as IT outsourcing companies. This standard requires an organization to assure customers that their information is being protected.
ISO 27001:2013 looks very different to ISO 27001:2005. There are no duplicate requirements, and the requirements are phrased in a way, which allows greater freedom of choice on how to implement them. A good example of this is that the identification of assets, threats and vulnerabilities is no longer a prerequisite for the identification of information security risks. The standard now makes it clearer that controls are not to be selected from Annex A, but are determined through the process of risk treatment. Nevertheless, Annex A continues to serve as a cross-check to help ensure that no necessary controls have been overlooked.
ISO 27001 helps the organization to:
- Analyze risks related to information security
- Define specific and optimal security goals (the standard requires a company to specify its own security goals which an auditor verifies)
- Define defined and documented methods which all activities should follow
- Document all risks, goals, and methods
- Implement measures to mitigate and manage risks
- Assign accountability for risk management
- Measure information security
- Embed continuous improvement approach
