Which of the following is true of removable media and portable electronic devices (PEDs)?

The assertion that the risk associated with removable media and portable electronic devices may lead to loss of life is valid, especially in the context of military and defense environments. Such devices often contain sensitive or classified information that, if compromised, could pose significant security threats. This breach could lead to operational failures, unauthorized access to critical data, and ultimately, could impact the safety and effectiveness of military personnel or missions.

While other options present certain truths about security policies and risks, they do not fully encompass the potential severity of the threats associated with these devices. The focus on loss of life highlights the extreme consequences of data breaches and illustrates why robust cybersecurity measures are essential when dealing with removable media and PEDs in sensitive environments.
