. In the event that Rasputin used SQL injection to attack the network systems of more than 60 universities and stole their information, which layer of the IOT architecture was attacked? A.Perception layer B.Network layer C.Management layer D.Application layer

Rasputin, al utilizar la inyección SQL para atacar los sistemas de red de más de 60 universidades y robar su información, atacó la Capa de Aplicación (D) de la arquitectura de IOT. La inyección SQL es un tipo de ataque que se realiza en la capa de aplicación, ya que es donde se procesan las consultas SQL.

The layer of the IOT architecture that was attacked in the event that Rasputin used SQL injection to attack the network systems of more than 60 universities and stole their information is the Application layer (D).

Here's why:

1. Perception Layer: This is the physical layer that includes the devices and sensors that interact with the environment. It's not relevant in this case because the attack was not on the physical devices or sensors.

2. Network Layer: This layer is responsible for transmitting the data collected by the perception layer to the different nodes of the system. While SQL injection can be used to exploit vulnerabilities in a network, it's not the primary target in this case.

3. Management Layer: This layer is responsible for managing and processing the data collected. It's not the primary target in this case because the attack was not on the data management or processing systems.

4. Application Layer: This layer is where the applications and services that use the data reside. SQL injection is a code injection technique, used to attack data-driven applications. In this case, Rasputin used SQL injection to attack the network systems of the universities, which are data-driven applications. Therefore, the Application layer was the one attacked.
