Interested party

Would like some clarifications for the below query
I see in the standard the use of terms such as
-          Suppliers ( A15 )
-          Contractors ( A.16.1.3 )
-          External parties ( A5.1.1 )
-          Interested parties
 

Answer:

All these terms are related to the same thing (although a supplier is an entity that gives you a service, and contractors can be individual external persons that works in your company): Interested parties, and what is it? Basically an interested party can be persons or organizations that can influence your information security business continuity. For more information about interested parties you can read this article “How to identify interested parties according to ISO 27001 and ISO 22301” : https://advisera.com/27001academy/knowledgebase/how-to-identify-interested-parties-according-to-iso-27001-and-iso-22301//
