Final answer:
The behavior that is NOT associated with potential malicious insiders is ethical use of resources.
Step-by-step explanation:
The behavior that is NOT associated with potential malicious insiders is c. Ethical use of resources. Potential malicious insiders are individuals who have authorized access to sensitive information and computer systems but may misuse their privileges for personal gain or harm. Unauthorized access to sensitive information (a), sabotage of computer systems (b), and intentional spreading of malware (d) are all behaviors associated with potential malicious insiders. Ethical use of resources, on the other hand, refers to using resources in a responsible and morally correct manner, which would not fall under the category of potential malicious insider behavior.
