Debunking some common myths about ISO/IEC 27001, the information security management system (ISMS) standard
Debunking some common myths about ISO/IEC 27001, the information security management system (ISMS) standard
ISO/IEC 27001 is the best-known international standard for information security management systems (ISMS). It defines the requirements for establishing a framework to manage an organization’s information assets in a way that safeguards confidentiality, availability and integrity of data stored or processed. However, there are myths that surround the implementation of an ISMS and what ISO/IEC 27001 requires. We debunk some of these myths and misconceptions in the present article.
Myth 1: ISO/IEC 27001 is only for IT companies
While ISO/IEC 27001 includes technological controls, many of which are focused on IT aspects, the standard can be applied by any organization, regardless of what it does and of what information it must protect. There are also organizational controls, physical controls and people controls in the standard, which apply to organizations operating in any other sectors. However, it’s true that the vast majority of companies implementing information security management systems according to ISO/IEC 27001 operate in the IT sector or rely significantly on IT to conduct their operations.
Myth 2: ISO/IEC 27001 guarantees 100% security
This is what many believe. That if a company implements a management system for information security, then this means that they are 100% secure. But achieving an ISO/IEC 27001 certification does not mean the organization is completely secure from cyber and other security threats. This standard helps businesses implement a systematic risk-based approach to managing information security. However, no system is immune to attacks, but the expectation is that an organization that has an effective ISMS in place can better manage security aspects, prepare for and respond to attacks effectively.
Myth 3: Only large enterprises can implement ISO standards, especially ISO/IEC 27001
One of the biggest misconceptions is that ISO/IEC 27001 is designed only for large corporations with extensive IT infrastructure. In reality, the standard is applicable to organizations of all sizes and industries. Whether you are a small startup or a multinational corporation, implementing ISO/IEC 27001 can help protect sensitive information, reduce security risks, and enhance customer trust.
Myth 4: ISO/IEC 27001 means a checklist that needs to be filled out
Some people think that implementing a management system and compliance with a standard such as ISO/IEC 27001 means filling out a checklist. In reality, there’s more work to do. An effective management system needs the involvement of multiple stakeholders in the organization, especially the support from the company’s top management.
Myth 5: ISO/IEC 27001 is sufficient for privacy compliance
Another common misconception is that the implementation of an ISMS according to ISO/IEC 27001 is sufficient for meeting privacy and data protection requirements, such as those under GDPR or other privacy regulations. While ISO/IEC 27001 provides a strong foundation for securing information, it does not fully address all privacy-specific obligations, such as data subject rights, lawful processing or privacy by design and by default. Organizations dealing with personally identifiable information should also consider implementing ISO/IEC 27701, which is an extension for privacy to ISO/IEC 27001 and ISO/IEC 27002.
Myth 6: Only the IT guys are responsible for ISO/IEC 27001 implementation
Information security is not just the responsibility of IT teams—it’s a shared responsibility and it involves everyone in the organization. Employees at all levels must be aware of security policies, follow best practices and play an active role in protecting information assets. Senior management involvement is also crucial for driving a security-conscious culture.
Conclusion
ISO/IEC 27001 is an excellent tool for any organization looking to manage information security effectively. However, misconceptions, such as those enumerated above,
prevent organizations from fully understanding its value and benefiting from the implementation and use of an ISMS. Whether you are a small business or a large corporation, ISO/IEC 27001 provides a structured framework to protect your information assets and build trust with stakeholders.
