What is not recommended for use with "Strict-Trust Enforced"?

"Strict-Trust Enforced" is a security setting that requires the use of trusted SSL certificates to establish secure connections. The reason why self-signed certificates are not recommended in this context is that they are not issued by recognized certificate authorities (CAs), which means they lack the inherent trust that relies on a third-party verification process.

When utilizing "Strict-Trust Enforced," only certificates that have been validated and recognized as trustworthy should be used to prevent man-in-the-middle attacks and ensure that the communication is genuine and secure. Trusted SSL certificates come from reputable CAs and therefore meet the requirements of "Strict-Trust Enforced." Similarly, third-party certificates can be trusted if they come from a reliable CA.

In contrast, all SSL certificates are not universally disallowed under this setting; only self-signed certificates fall outside the recommended practices because they do not provide the necessary trust validation that "Strict-Trust Enforced" requires.
