What measures help ensure data integrity in C2 networks?

• A. Rely solely on physical security without encryption.
• B. Use open, unencrypted protocols to speed up data flow.
• C. Encryption, authentication, redundancy, and robust network protocols to prevent spoofing, tampering, and outages.
• D. Disable redundancy to simplify networks.

Answer: (C)

Data integrity in C2 networks means ensuring commands and responses travel from the true source to the intended destination without being altered, spoofed, or replayed, and that the communicating devices are properly authenticated. Achieving this requires a layered approach. Encryption with authentication protects the contents from eavesdropping and, when paired with authenticated encryption, detects any tampering. Authentication verifies the identities of endpoints, preventing impersonation and man-in-the-middle attacks. Robust network protocols provide built-in integrity checks such as message authentication codes, sequence numbers, and replay protection, so any modification or out-of-order delivery is detected. Redundancy adds alternative paths and failover capabilities, keeping the channel available even if parts of the network fail. This resilience helps maintain the integrity of data delivery by avoiding outages that could otherwise lead to data loss or inconsistent states. Together, these measures prevent spoofing, tampering, and outages, providing a trustworthy C2 communication channel. Relying solely on physical security misses threats that occur over the network; using open, unencrypted protocols leaves data exposed to interception and modification; disabling redundancy increases the risk of outages that can disrupt or corrupted data flows.
