c)To apply security controls​

Answer 1

Answer:

to apply security controls.

Answer 2

Answer:

c)To apply security controls​

Explanation:-

In any system of interacting components, identification of these components is needed in order to ensure the correct composition and operation of the system. This applies to all lifecycle phases of a system from development to assembly, commissioning, operations, maintenance and even end of life. Especially in case of flexible and dynamic interactions between system components identification plays an

important role. Identifiers are used to provide identification. In general an identifier is a pattern to uniquely identify a  User identifiers identify users of IoT applications and services. Users can be humans, parties (e.g. legal

entities) or software applications that access and interact with the IoT application or service single entity (instance identifier) or a class of entities (i.e. type identifier) within a specific context. A human logs into an IoT system in order to get some data from or to control the thing of interest. The human has to identify itself (e.g. username, chip card, fingerprint) to the system. Depending on the security needs an additional authentication is performed. The system checks that the user has the proper rights to access the thing or services and performs the intended actions. The user’s rights depend on its (assigned) specific role in the given scenario. Within the IoT system, the user is assigned a specific identifier which is used for all trust/security associations and which might be different from the identifier used by the human for identification.
