Visible Red

The term Visible Red refers to a term used in some COMSEC contexts for cryptographic keying material that is unencrypted or otherwise exposed in plaintext-equivalent form and therefore requires strict protection. It gives election, security, legal, or technical readers a specific label for the concept rather than a broader everyday meaning.

In practice, Visible Red is applied to the technical or security purpose captured by its definition: a term used in some COMSEC contexts for cryptographic keying material that is unencrypted or otherwise exposed in plaintext-equivalent form and therefore requires strict protection. Organizations combine that function with documented procedures, authorized access, testing, monitoring, and controls appropriate to the system.

Understanding Visible Red matters because the concept can affect security, reliability, auditability, or trusted operation. In this glossary context, it refers to a term used in some COMSEC contexts for cryptographic keying material that is unencrypted or otherwise exposed in plaintext-equivalent form and therefore requires strict protection.
