Final answer:
Allowing network users to delete certain files from a directory is an example of user privilege control.
Step-by-step explanation:
Allowing network users to delete certain files from a directory is an example of User privilege control. User privilege control refers to the ability to manage and restrict the actions that users can take within a network. By granting certain users the privilege to delete files, administrators can control who has the authority to modify or remove files.
This privilege control is different from Strict security measures, which involve implementing various strategies to protect a network from unauthorized access and potential threats.
It is also different from Data encryption, which involves encoding data to protect it from unauthorized access. While data encryption can help maintain the confidentiality of files, allowing or disallowing users to delete them is a separate access control decision.
