What is the primary concern of the company when they clean whiteboards and clear desks before a tour?

The primary concern of the company when they clean whiteboards and clear desks before a tour is to mitigate the risks associated with social engineering. Social engineering involves manipulating individuals to gain confidential information or access to their systems and data. By eliminating visible notes, diagrams, or sensitive information that might be left on whiteboards or desks, the company aims to reduce the potential for someone to leverage that information to facilitate social engineering attacks.

When visitors tour a facility, they could inadvertently or intentionally observe sensitive information that could be used against the company, leading to security breaches or the exploitation of proprietary information. Therefore, the best practice of cleaning up before a tour directly addresses this concern, ensuring that the company maintains its security posture against such manipulative tactics.

Loss of proprietary information, damage to the company's reputation, and credential exposure are valid concerns but are not the primary focus when preparing for a visitor's tour. The emphasis is primarily on safeguarding against information that could be exploited through social interactions rather than direct theft or damage.
