In addition to fines, what can happen to a security officer's license for violating regulations?

The correct answer highlights that a security officer’s license can be revoked for violating regulations. Revocation is a serious consequence that signifies a complete loss of the ability to legally practice as a security officer. This action is typically taken in response to significant breaches of conduct that compromise the safety and security responsibilities inherent in the role. Such severe penalties reflect the importance of adhering to established regulations and standards in the security profession.

When a license is revoked, it means the individual is no longer permitted to operate in that capacity until they can fulfill any requirements set forth by regulatory authorities, which may include reapplying for a license or meeting additional criteria. This serves as a deterrent to ensure that all individuals in this role maintain compliance with the law and uphold the integrity of the profession.

The other options involve alternative consequences that are less severe than revocation but do not fully capture the seriousness of the misconduct outlined. Upgrading a license or providing a warning without penalties does not typically occur in response to violations, as the focus is on maintaining safety standards in the industry. Temporary suspension may apply in certain cases but is not as unequivocal as revocation, which illustrates the most severe outcome of such violations.
