Measurement device and measurement method
In the measurement device, electrical characteristics of a component can be measured adequately even if the component size is small. In the measurement device, at least a part of the component holding section is an antistatic section made of an antistatic material. Since the surface resistance of the antistatic section is large, it is possible to measure the electrical characteristics of a component in a state where the component is held by the antistatic section. Therefore, even if the size of the component is small, scattering of the component is prevented and the electrical characteristics can be adequately measured. |

Upon detecting a suspect user attempting to interact with the production environment, one or more requests received from the suspect user are routed to the simulated environment layer as opposed to the production environment. At least one behavior of the simulated environment layer is then modified as the suspect user interacts within the simulated environment layer. The modified behavior facilitates that an attack initiated by the suspect user can proceed. Information (such as the user's tactics, techniques and procedures (TPPs), or other Indicators of Compromise (IoCs) associated with the attack is captured for analysis and subsequent action. |
