Security+ ยท 3.0 Security Architecture
Public Key Infrastructure (PKI)
The system of CAs (Certificate Authorities), certificates, CRLs (revocation lists), and trust stores that underpins TLS, code signing, and authenticated email (S/MIME).
How this shows up at NCAE
Your self-signed cert is not in any PKI. browsers/clients don't trust it. That's fine for the NCAE scoring engine in most configs, but understand the mechanism.
