ISO and IEC

Answer:

Although largely known as ISO 27001, to refer to the Standard only as ISO 27001 is inaccurate.

The full official name of this standard is ISO/IEC 27001:2013, because this standard was developed by a joint technical committee (ISO/IEC JTC 1) formed by these two organizations.

The participation of IEC in the development of this standard helps ensure that its content is aligned with standards developed by IEC without participation of ISO personnel, such as IEC 62351 Power System Control and Associated Communications – Data and Communication Security.

Additionally, not using the official name can lead people not used to ISO documents to the misinterpretation that there are more than one 27001 standard, which is not true.
