What role do refresher courses play in employee training regarding unauthorized disclosures?

Refresher courses serve a crucial function in employee training, particularly regarding unauthorized disclosures. These courses are designed to reinforce existing knowledge and ensure that employees are aware of the latest protocols and policies that govern data protection and confidentiality.

As regulations and security measures evolve, it's essential for employees to stay informed about any changes that could affect their handling of sensitive information. By regularly participating in refresher courses, employees can be reminded of their responsibilities, learn about emerging threats, and understand the potential consequences of unauthorized disclosures. This continuous education process helps foster a culture of awareness and vigilance within the organization, which is vital for maintaining data integrity and security.

In contrast, the other options imply limitations that do not align with the purpose of refresher courses. They are not optional, as ongoing education is necessary to adapt to an ever-changing environment; they are not solely for new hires because all employees need continuous training; and they are not restricted to technical skills as they encompass a broader spectrum of awareness and policy understanding.
