Which activity is most effective at reducing risk from naive end users?

Conducting a training session at the time of hire is particularly effective at reducing risk from naive end users because it equips them with essential knowledge about security practices and potential threats. When new employees are trained, they learn how to recognize phishing attacks, understand the importance of strong passwords, and follow protocols for handling sensitive information. This proactive approach fosters a culture of security awareness within the organization, ensuring that employees are not simply passive users of technology but active participants in maintaining security.

While configuring network intrusion-detection software and reconfiguring the network firewall are important for enhancing network security, they focus more on protecting the infrastructure rather than addressing the behavior and knowledge of the end users themselves. Assembling a team of security professionals is beneficial for managing overall security strategy, but it does not directly engage the end users who are often the weakest link in security protocols. Thus, immediate and practical training has a direct impact on decreasing human errors that can lead to security breaches.
