Which method is effective in preventing insider threats during the planning phase?

Conducting regular security awareness training is an effective method in preventing insider threats during the planning phase because it helps to educate employees about the importance of security protocols, the risks associated with insider threats, and the behaviors that should be avoided. By providing ongoing training, organizations can foster a culture of security awareness where employees understand their role in protecting sensitive information and recognize warning signs of potential malicious behavior.

This proactive approach can deter potential insider threats, as employees who are well-informed about security best practices are less likely to engage in risky behavior or fall victim to social engineering attacks. Additionally, training can empower employees to report suspicious activities or concerns, creating an environment of vigilance and accountability that is essential in mitigating insider threats.

Other options, such as encouraging social events without security presence, reducing surveillance of employees, or limiting information sharing to a few trusted personnel, may not effectively address the underlying issues related to insider threats and could potentially compound the risks by lowering awareness or increasing vulnerabilities.
