If you’re looking to implement ISO 27001, you need to know the basics. So please keep reading to learn about the requirements for ISO 27001, what benefits it can bring to your organization, and how to get started.
How ISO 27001 Works
ISO 27001 is a set of international standards for information security management. It provides businesses with a framework for identifying, assessing, and managing information security risks. Organizations certified for the ISO 27001 Standard demonstrate that they have implemented a comprehensive and robust information security management system. ISO 27001 comprises two parts: the requirements and the guidance. The requirements set out the specific controls an organization must implement to meet the standard. And the guidance provides more detailed instructions on how to implement each control. An organization can become certified to ISO 27001 by demonstrating that it has met the standard’s requirements and passed an audit by a third-party certification body.
The History of ISO 27001
The history of ISO/IEC 27001 goes back to 1999, when the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) formed a joint technical committee (JTC 1) called “Information technology – Security techniques.” The goal of this committee was to develop a standard for an information security management system (ISMS). In 2000, JTC 1 issued a call for proposals for a standard on these systems. This led to the development of two drafts: one from the British Standards Institution (BSI) and one from the American National Standards Institute (ANSI). In 2003, these two drafts into one proposal by JTC 1. In 2004, this proposal was balloted out by member countries, and it failed to achieve consensus. However, many countries saw the value in developing such a standard and voted favor of continued development. As a result, JTC 1 created a new working group specifically tasked with developing the standard. This new working group developed what would become ISO/IEC 27001:2005, published in 2005. The original ISO/IEC 27001 included 115 clauses divided into ten sections. Since its publication in 2005, ISO/IEC 27001 has been amended twice.
Basics of Audit and Compliance
An organization’s approach to information security should be based on a risk management framework. That framework should include an assessment of the risks to the confidentiality, integrity, and availability of information resources. The most commonly internationally recognized framework for information security is ISO/IEC 27001. An ISMS must include security policy, organization structure, asset register, risk assessment, and controls. Security policy sets out the organization’s approach to information security and is approved by senior management. It includes statements about how data will be protected and what sanctions will be applied if employees don’t comply with it. Organization structure identifies who within the organization is responsible for each aspect of information security and defines their roles and responsibilities. An asset register lists the company’s assets (e.g., hardware, software, data) along with the owner, location, and classification details. Risk assessment looks at how likely a particular threat could lead to a loss of data integrity, confidentiality or availability. It then prioritizes these risks so that appropriate countermeasures can be implemented. Finally, controls are specific measures to reduce or eliminate identified risks. They include technical controls (e.g., firewalls), administrative controls (e.g., password policies), and physical security measures (e .g., secure office space).
Benefits of ISO 27001 Certification
Some of these benefits of ISO 27001 include improved security, reduced costs, and enhanced reputation. In addition, obtaining ISO 27001 certification can also help organizations meet legal and compliance requirements.
Overall, the basics of ISO 27001 are important to understand to comply with the standard and protect an organization’s information effectively.
