Mitigating Controls (NIST 800-53 r5) AI
SC-8 directly requires protecting confidentiality of transmitted information, which structurally eliminates cleartext transmission of sensitive data.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.
Secure SDLC practices directly prevent embedding sensitive data in query strings as part of input-handling and data-flow design.

Specifying encryption and other security technology for network services prevents transmission of sensitive information in cleartext over potentially untrusted channels.
Security testing can detect sensitive data leakage via query strings.
Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.
Specifying communications-security requirements and secure remote-access methods (including encryption expectations) prevents the transmission of sensitive data in cleartext over home or public networks.
Armoured conduits, electromagnetic shielding and locked enclosures make passive eavesdropping on unencrypted traffic traversing the cables more difficult, mitigating exposure of sensitive data in transit.
DLP solutions can detect and block sensitive data in URLs.
