Which example best represents insider threats?

Insider threats refer to risks posed by individuals within an organization, such as employees or contractors, who exploit their access to sensitive information or systems for malicious intent or personal gain. The best representation of an insider threat among the examples provided is the scenario where an employee modifies company data for personal gain. This demonstrates a clear abuse of access and privileges, highlighting a breach of trust and integrity within the organization.

Modifying company data can have significant repercussions, including financial loss, reputational damage, and disruption of business operations. The intent to manipulate data indicates a calculated action that directly harms the organization, which aligns closely with the definition of insider threats.

While the other options may depict behaviors that could suggest issues within the workplace, such as tardiness or stealing sensitive information, the act of modifying data specifically showcases a malicious exploitation of access that is characteristic of insider threats.
