Todays Internet has a growing number of protocols and mechanisms to protect data in transmission. One can choose from IP Security (IPsec), Transport Layer Security (TLS), and many other protocols. However, security protocols and mechanisms are not widely used because of usability issues  and because users often underestimate the risk their data is exposed to. An approach to solve this problem consists of automated selection and configuration of available security protocols in a user transparent way. In this paper we present a method for automatically choosing the right security protocol based on Security, Quality of Service, and Energy Consumption aspects. We describe the necessary aspects, value functions, and a hierarchical, flexible, and efficient decision process.
