Certificate Transparency
Certificate Transparency is a system that logs SSL/TLS certificates to enhance security and trustworthiness.
Definition
Certificate Transparency (CT) is a security framework designed to provide transparency for SSL/TLS certificates. It aims to prevent the issuance of fraudulent certificates by making the issuance process visible to the public via log servers. When a certificate is issued, it is logged in a public CT log, allowing domain owners and browsers to monitor and verify the certificates associated with their domains.
This system enhances trust in the certificate authorities (CAs) and helps ensure that only legitimate certificates are used. For example, a website owner can check CT logs to confirm that no unauthorized certificates have been issued for their domain.
Why It Matters
For SEO, Certificate Transparency is crucial as it helps prevent phishing attacks, thereby protecting user data and enhancing the site's reputation with search engines.
Example
A website owner can verify their certificate's presence in a CT log by visiting Certificate Transparency logs and searching for their domain.
