　　Security components

　　Security in any system requires a multilayered approach. Although data encryption often gains the most attention among security measures， it is only one aspect of a robust security policy. Black-hat methods such as man-in-the-middle attacks exploit any weakness well before encrypted data exchange begins. Indeed， secure hosts authenticate clients to ensure that only authorized users， devices， or other systems gain access. Conversely， those clients authenticate the host to verify its identity.

　　This kind of mutual authentication lies at the heart of secure applications， but it ultimately relies on more fundamental mechanisms and policies. Foremost among these， secret keys and an established root of trust are the building blocks of any secure application. In the kind of public key infrastructure （PKI） typically used on the Internet， public keys paired with secret private keys provide essential validation of an entity’s identity. The X.509 certificate standard wraps the entity’s public key in a broader context that documents that identity， building on a chain of certificates to provide a solidly grounded root of trust for the application.
