How works ISO 27001?

some question in my minds please clear me how is works 20001 & 27001 and what is the benefits after taking and what about the profits after implementation
 

Answer:

ISO 27001 works establishing requisites for the implementation of an Information Security Management System (ISMS), so basically here it is important to identify risks and reduce them, for the protection of the information. For more information, please see this “What is ISO 27001?” : https://advisera.com/27001academy/what-is-iso-27001/
Regarding “20001” I am sorry but it is not a standard. You mean ISO 20000-1 or ISO 22301?
Regarding benefits and profits after implementation, generally you can consider 4: compliance, marketing edge, lowering the expenses and putting your business in order. For more information about this, please read this article “Four key benefits of ISO 27001 implementation” : https://advisera.com/27001academy/knowledgebase/four-key-benefits-of-iso-27001-implementation/
