What incident refers to a person gaining access to system and network resources without authorization?

The incident that refers to a person gaining access to system and network resources without authorization is accurately described as an Unauthorized Access Incident. This type of incident highlights a breach where individuals exploit vulnerabilities or weaknesses in security protocols to access systems, data, or networks they are not permitted to use.

Unauthorized access can have significant implications, including data theft, system integrity issues, and privacy violations. Understanding this concept is crucial in incident handling, as identifying and responding to unauthorized access is one of the primary responsibilities of an incident handler. This knowledge enables organizations to develop strategies and responses to mitigate such risks effectively.

The other options presented focus on different aspects of incident handling or situations where access is permitted or managed improperly. Handling Inappropriate Usage might cover behavioral issues rather than outright unauthorized access, Handling Multiple Component Incidents typically refers to incidents involving several interconnected systems, while Authorized Access Incident would pertain to legitimate access scenarios.
