Secret Clearance involves a formal background investigation for access to classified information, primarily in government and defense sectors. Security Officers typically perform security patrols and access control, often requiring security training but not a clearance. While both roles focus on security, Secret Clearance is a credential granting access to sensitive information, whereas Security Officers focus on physical security and safety.
