Security Certificates Overview
How Certificates Work
X.509 certificates are a security technology that assists networked computers
in determining whether to trust each other.
• A single, centralized certificate authority (CA) is established. Typically,
this is either an enterprise’s IT department or a commercial certificate
authority.
• Each computer on the network is configured to trust the central certificate
authority.
• Each server on the network has a public certificate that identifies it.
• The certificate authority signs the public certificates of those servers that
clients should trust.
