A high school principal wants to share the emergency response plan through an app. What is the first necessary action to ensure proper use?

The correct choice emphasizes the importance of security features in the app that are critical for safeguarding the emergency response plan. Ensuring that the app has robust security measures is essential because this sensitive information must be protected against unauthorized access or tampering. With security features in place, the principal can confidently share information, knowing that it is safeguarded from potential breaches that could compromise the safety and effectiveness of the emergency response plan.

Implementing security features helps maintain the integrity of the information, ensuring that all users interact with a consistent and unaltered version of the emergency response plan. This is especially important in emergency situations, where accurate and timely information can have significant consequences.

While other options might pertain to important aspects like compliance with legal regulations or user agreements, they do not address the fundamental requirement of securing the content and ensuring that it remains reliable and trustworthy. Without adequate security, even a well-informed user group could be at risk if the information is not protected.
