What is data integrity and why is it critical in cyberspace operations? Provide one common method to ensure it.

• A. Assurance that data has not been altered or corrupted; use cryptographic hashes or digital signatures to verify integrity.
• B. Data integrity is the same as data availability; use backups.
• C. Data integrity relates to authentication only; use passwords.
• D. Data integrity is about data encryption; use TLS.

Answer: (A)

Data integrity means ensuring that data has not been altered or corrupted from its intended state. In cyberspace operations, this matters because decision-making, situational awareness, and mission outcomes depend on trustworthy information. If data is tampered with or corrupted, it can lead to wrong conclusions, degraded performance, or exploitable vulnerabilities. A common way to ensure integrity is to use cryptographic hashes or digital signatures. A hash creates a compact fingerprint of the data; if any bit changes, the hash changes inexplicably, so you can verify that the data you have matches the original. Digital signatures take that a step further by signing the hash with a private key, allowing others to confirm both the data’s integrity and its authenticity with a public key. This combination makes tampering detectable across storage and transmission.
