Key concept of ISMS

Could you share the key concept of ISMS?
 

Answer:

From my point of view, the key concept of an ISMS is the information (and its protection). And it is also one of the more important things in our current age (information age). How can we protect the information? Basically identifying risks and reducing them, and it is also covered by an ISMS (the risk is also an important concept in an ISMS).
