non-security information

The phrase is the straightforward logical complement of the defined term "security information" — defined by NIST SP 800-37 Rev. 2 as information within a system that can potentially impact the operation of security functions or the provision of security services. "Non-security information" therefore denotes any information residing in or processed by a system that does **not** meet that threshold — content whose compromise, modification, or disclosure would not affect security enforcement mechanisms, security policy, or the isolation of security-relevant code and data. In context it serves as a residual or exclusionary category, used to draw a boundary around the scope of a security control or analysis by naming what falls outside it, rather than labeling a substantive class of data in its own right.
