ISO what?

The ISO (International Organization for Standardization) and the IEC (International Electrotechnical Commission) provide a globally recognized framework for best-practice information security management: the ISO/IEC 27000 family of mutually supporting information security standards (also known as the ISO 27000 series).

The most well-known of the series is ISO 27001, which sets out the specification for an ISMS (information security management system).
The series is developed and published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

Why use an ISO 27000-series standard?

Information security breaches are one of the most significant risks that organizations face. Sensitive data is used across all areas of businesses these days, increasing its value for legitimate and illegitimate use.

Wherever the data goes, the financial and reputational damage caused by a breach can be devastating.

That’s why organizations are increasingly investing heavily in their defenses, using ISO 27001 as a guideline for effective security. ISO 27001 can be applied to organizations of any size and in any sector, and the framework’s broadness means its implementation will always be appropriate to the size of the business. A recent study from Attivo Networks noted that 37% security professionals using some form of security framework, are using the ISO 27000 family of standards.

ISO 27000 Series

ISO 27001

ISO 27001 is the central standard in the ISO 27000 series, containing the implementation requirements for an ISMS. This is important to remember, as ISO 27001 is the only standard in the series that organizations can be audited and certified against.

That’s because it contains an overview of everything you must do to achieve compliance. 

ISO 27002

ISO 27002 is a supplementary standard that discusses the information security controls that organizations might choose to implement.

Organizations are only required to adopt controls that they deem relevant – something that will become apparent during a risk assessment.

The controls are outlined in Annex A of ISO 27001. Still, whereas this is essentially a quick rundown, ISO 27002 contains a more comprehensive overview, explaining how each control works, what its objective is, and how you can implement it.

ISO 27005

ISO 27005 is the international standard that describes how to conduct an information security risk assessment per the requirements of ISO 27001.

Risk assessments are one of the essential parts of an organization’s ISO 27001 compliance project. ISO 27001 requires you to demonstrate evidence of information security risk management, risk actions are taken, and how relevant controls from Annex A have been applied.

ISO 27005 applies to all organizations, regardless of size or sector. It supports the general concepts specified in ISO 27001 and is designed to assist the satisfactory implementation of information security based on a risk management approach.
