What does the Navy employ to protect sensitive information during assessments?

The Navy employs layered security protocols to protect sensitive information during assessments. This approach involves using multiple defensive mechanisms to safeguard data, ensuring that if one layer is compromised, multiple other layers still protect the information. Layered security can include a combination of physical security measures, such as controlled access to facilities, along with technical security measures, such as encryption and secure communication channels, as well as administrative controls like user training and access management policies. This multiplicity of defenses not only helps in enhancing overall security but also makes it more challenging for unauthorized users to access sensitive data.

The other options do not offer adequate strategies for safeguarding sensitive information. For example, audio surveillance is primarily used for monitoring conversations rather than protecting data. Public access systems could inadvertently expose information rather than secure it. Minimal technological support would likely leave sensitive data vulnerable, lacking the required protections against potential threats. Therefore, the selection of layered security protocols represents the most robust and effective strategy within the context of Navy operations.
