The chain of trust in Apple’s devices

A lot of computer security is based on trust. Your devices verify that you are, indeed, an authorized user, through the use of user names and passwords. And your devices trust services and servers, through a series of certificates and “trusted third parties” who work through a cascading system of verification and authentication.

Each link of this chain is carefully designed to ensure its reliability, and each link also enhances other links in the chain. This can seem complex, but when you break it down into its component parts, it’s a lot easier to understand.
