What are the typical classification levels for shipboard interior networks based on data sensitivity?

• A. Secret only
• B. Secret, UNCLASS, and Top Secret/Sensitive Compartmented Information (TS/SCI)
• C. Confidential
• D. Unclassified

Answer: (B)

Shipboard interior networks are labeled to reflect data sensitivity so that access can be properly controlled. The typical spectrum includes Unclassified for non-sensitive information, Secret for information that must be protected against unauthorized disclosure, and Top Secret with Sensitive Compartmented Information (TS/SCI) for the most sensitive material that requires additional compartmentalization and strict access control. This three-level framing—Unclassified, Secret, and Top Secret/TS-SCI—captures the standard range of network classifications used to govern who can access what. The other options fail because they omit one or more of these essential levels (for example, listing only one level or excluding TS/SCI or Unclassified).
