Which principle describes that access to sensitive or restricted information is controlled?

The principle that describes access to sensitive or restricted information being controlled is security. Security encompasses measures and protocols that protect data and systems from unauthorized access, ensuring that only individuals with the appropriate permissions can view or manipulate sensitive information. This is essential in maintaining confidentiality and safeguarding against breaches that could compromise important data.

In the context of the incident command system, maintaining security is critical to ensure that only those with the need to know can access sensitive operational details, thus protecting the integrity of the response efforts and victims' information. Recognizing the importance of security helps facilitate a trust-based environment where information is securely managed and shared appropriately among authorized personnel.
