ISDS Information Privacy and Security (ISDS 418) Practice Exam

The term that best fits the definition of a security event where an unauthorized entity attempts to access a system is "intrusion." Intrusion specifically refers to any unauthorized access into a computing environment, network, or system. It highlights the action of infiltration by an external agent who is trying to breach security measures without permission.

Understanding the context of other terms is essential. "Inhibition" does not align with the concept of unauthorized access; rather, it implies a form of prevention or restraint. "Exfiltration" pertains to the unauthorized transfer of data out of a system, usually after a successful intrusion, rather than the attempt to access the system itself. "Mitigation” refers to the strategies and measures put in place to reduce risk and impact, which occurs after an event is detected, rather than being a type of event itself.
