SSL: How it works and appropriate use cases of the technology

摘要

1. SSL is a flexible security technology that can be used in multiple ways to add value to what has been previously considered "VPN" solutions. 2. In most Internet deployment situations, much of the cons associated with using SSL are mitigated and made less significant by firewalls, NATs, and other devices in the network path. 3. The most relevant use cases for SSL are either embedding SSL into an application protocol such as POP, HTTP, FTP, etc or just below the application protocol layer.
