Which category of unauthorized access is associated with changes in system status?

The category of unauthorized access associated with changes in system status is Physical Intruder. This type of access involves physically breaching security measures to gain control over a system, which can lead to significant alterations in its operational status.

When a physical intruder gains access to a facility or system, they often have the ability to manipulate hardware, disable security protocols, or install unauthorized devices. This direct access can result in changes to system settings, configurations, or even complete system failures.

In contrast, the other options primarily address different aspects of unauthorized access. Unauthorized Data Access focuses on accessing confidential information without permission but does not inherently involve changes to system status. Unauthorized Usage of Standard User Account pertains to the misuse of legitimately assigned accounts to access systems or data but does not necessarily impact system operating conditions. Unauthorized Data Modification involves altering data itself without permission, which may not always lead to changes in the overall system status.

Understanding these distinctions helps clarify why the correct answer is linked to changes in system status, specifically through physical intrusion.
