What steps should be taken when an employee with access to classified information leaves an organization?

When an employee with access to classified information leaves an organization, conducting an exit interview and revoking access privileges is a crucial procedure for several reasons.

First and foremost, the exit interview presents an opportunity to discuss the importance of safeguarding classified information, reinforcing the confidentiality obligations that the departing employee has under any non-disclosure agreements or security clearances. This conversation can help remind the employee of their continuing responsibilities even after they leave the organization.

Revoking access privileges is equally critical. It ensures that the departing employee no longer has the means to access sensitive information, which is vital for maintaining the organization’s security posture. Without this action, there remains a risk that the former employee could inadvertently or intentionally expose classified information to unauthorized individuals, which could result in severe consequences for national security and the organization's integrity.

Increasing security measures temporarily or notifying all employees of the departure, while possibly beneficial in some contexts, do not directly address the immediate need to secure classified information from potential unauthorized access. Informing only the legal department also falls short, as it is essential to take proactive measures that directly involve the security of classified material. Thus, conducting an exit interview and revoking access privileges is the most comprehensive approach to mitigate risks associated with the departure of an employee with classified information
