CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-319Cleartext Transmission of Sensitive Information1,042Directly prevents cleartext transmission of sensitive information by requiring encryption or equivalent confidentiality protections during transit.
CWE-598Use of GET Request Method With Sensitive Query Strings75Protects sensitive data placed in query strings from interception in transit when confidentiality controls like HTTPS are enforced.
CWE-300Channel Accessible by Non-Endpoint53Renders the transmission channel inaccessible to non-endpoint eavesdroppers through encryption, eliminating the weakness class.
CWE-523Unprotected Transport of Credentials20Prevents unprotected transport of credentials by mandating confidentiality mechanisms such as TLS for all sensitive data flows.
