ISO 27001 definition: What is ISO 27001?

24/09/2021

ISO/IEC 27001:2013 (also known as ISO27001) is the international standard for information security. It sets out the specification for an information security management system (ISMS). The information security management system standard’s best-practice approach helps organizations manage their information security by addressing people, processes, and technology.

Certification to the ISO 27001 Standard is recognized worldwide as an indication that your ISMS is aligned with information security best practices.

Part of the ISO 2700 series of information security standards, ISO 27001 is a framework that helps organizations “establish, implement, operate, monitor, review, maintain and continually improve an ISMS”.

The latest version of the ISO 27001 information security standard was published in September 2013, replacing the 2005 iteration. 

What is an ISMS?

An ISMS is a holistic approach to securing the confidentiality, integrity, and availability (CIA) of corporate information assets. It consists of policies, procedures, and other controls involving people, processes, and technology.
Informed by regular information security risk assessments, an ISMS is an efficient, risk-based, and technology-neutral approach to keeping your information assets secure.

ISO 27001 benefits
