Which of the following is NOT considered a significant threat from employees to information systems?

The correct answer identifies that logic bombs are not typically categorized as a significant threat from employees compared to the other options. Logic bombs are a form of malicious code that execute under specific conditions, and while they can indeed pose a threat, they are often more associated with external attackers or could be the result of malicious software from unauthorized sources rather than a direct action taken by an employee.

In contrast, IT sabotage, fraud, and theft of intellectual property represent more common employee-related risks. Employees with access to sensitive systems and information may exploit their privileges to engage in sabotage, manipulating or destroying data intentionally, leading to significant operational disruptions. Fraud entails the misuse of corporate resources for personal gain, which employees are often in a position to commit. Similarly, employees may have the ability to access and misappropriate intellectual property, which can lead to substantial competitive and financial losses for an organization.

These threats stem from insiders who are familiar with the organization's systems and processes, making them particularly dangerous as they may bypass conventional security measures. In conclusion, while logic bombs are certainly a concern in cyber security, they do not specifically align with the common and significant threats posed by employees.
