Which of the following describes the insider threat effectively?

The description that employees may inadvertently cause security breaches effectively captures a significant aspect of the insider threat. An insider threat is not always a malicious act; it can stem from employees who, through negligence or lack of awareness, compromise security protocols unintentionally. For instance, someone might fall victim to a phishing attack or mishandle sensitive information, leading to potential data breaches. This highlights the importance of training and awareness programs within organizations to mitigate such risks, as even well-intentioned employees can pose a security threat if they do not understand the implications of their actions or the security measures in place.

Other descriptions, while they touch on aspects of employee behavior, do not address the core of the insider threat as directly. Offering invaluable insights into products, exhibiting complete trust in their access, or being a primary source of innovation may highlight the positive contributions of employees but do not convey the risk associated with potential security breaches that can arise from their actions.
