In a theft of proprietary information case, which of the following steps is most important to the security manager?

While not displaying sensitive products at trade shows may reduce immediate exposure, it does not constitute a comprehensive security strategy. This step alone does not actively protect the information from potential theft or breaches that could occur through other means, such as cyber attacks or insider threats.

Training employees to classify information is an important aspect of information security, but it focuses on awareness rather than direct protective measures. Classification helps manage information sensitivity, but without active security protocols in place, such training may not prevent data breaches or unauthorized access.

While legal protections like patents and trademarks can provide some level of security against theft, they do not prevent unauthorized access or cyber intrusions. These measures serve more as a legal recourse after a theft has occurred rather than an active step taken to secure the information in the first place.
