Which of the following activities may increase the risk of an insider threat incident?

The activity that may increase the risk of an insider threat incident is the implementation of new computer software or systems. When new technology is introduced, it can create vulnerabilities within an organization for several reasons. Employees may not be fully trained on the systems or may not understand how to use them securely, leading to unintentional mistakes that could expose sensitive information. Additionally, new software often comes with its own set of security gaps that may not yet be addressed, making it easier for malicious insiders to exploit these vulnerabilities. Furthermore, if employees feel uncertain or threatened by these changes, they might resort to harmful behavior, either out of fear of job loss or resentment towards management.

In contrast, regular training sessions, while being a positive practice, generally serve to educate and reduce risk by keeping employees informed about security measures. Increased salary may improve morale and loyalty but is not directly linked to insider threats. Mandatory vacations are usually a preventive measure employed to disrupt the work patterns of potential insider threats, allowing for the detection of any unusual activities during an employee's absence.
