What are the three models of trust?

What will be an ideal response?

There are three models of trust:
* Trust everyone all of the time-With this model, all employees are completely trusted to perform the correct actions, and therefore everyone is given full access and control over all information technology resources. This is the easiest model to enforce because there are no restrictions: everyone is "on their honor" to do the right thing. However, this is impractical.
* Trust some people some of the time-This approach exercises caution in the amount of trust given. Access is provided as needed with technical controls to ensure the trust is not violated.
* Trust no one at any time-This model is the most restrictive and fully protects all information technology resources.However, it is impractical.Few people would work for an organization in which they were not given at least some degree of trust.
