Employee training is not considered a physical security measure. However, it plays a crucial role in maintaining a secure environment. Employees are often the first line of defense against security breaches. By providing training on security protocols, companies can ensure that employees are aware of potential threats and are equipped to respond appropriately. This can include training on password security, identifying suspicious activity, and emergency response procedures. Regular training sessions can help to reinforce the importance of security and ensure that employees are prepared to handle potential security incidents.
