Which policy imposes strict restrictions on all company computers regarding network and system usage?

The Paranoid Policy is characterized by its strict restrictions on network and system usage across all company computers. This approach typically underscores the importance of data security and aims to minimize potential risks associated with network access. Organizations that adopt this policy often implement rigorous controls, including extensive monitoring and limited access rights, to ensure that all user activities adhere to security protocols. This type of policy often sees heightened security measures to protect sensitive data, providing an environment where end-users have minimal freedom to operate beyond defined limits.

While the other policies may focus on different management styles or flexibility regarding access and usage, they do not embody the strict control measures and restrictions that are hallmark features of the Paranoid Policy.
