Episode 17 — Demystify Certificates, PKI, and Trust Chains that Power Secure Communication
The Public Key Infrastructure (PKI) acts as the trust engine of the digital world, and this episode demystifies the certificates and trust chains that secure our online interactions. We define a digital certificate as a technical document that binds a public key to a specific identity, and we explain the role of the Certificate Authority (CA) as the trusted third party that signs these documents. You will learn how your browser uses a "trust chain" to verify that a website’s certificate was issued by a legitimate CA found in your local root store. On the GISF exam, you must understand the certificate lifecycle, including the importance of revocation lists (CRLs) and the Online Certificate Status Protocol (OCSP). We discuss common scenarios where certificate errors occur, such as expired keys or domain mismatches, providing a professional troubleshooting perspective. Mastering PKI is essential for securing web traffic, email, and administrative sessions across the enterprise.
