Encrypting SQL Server Connections

Jamie Wick has a great post showing how you can encrypt connections to SQL Server:

So, a question that should be asked is: How secure are your client connections? Here are a couple common misconceptions about SQL server client connections.

Misconception: Usernames & passwords (SQL or Windows) are used to connect to SQL server databases, which means the client-server connection is secure.

Explanation
Usernames & passwords are used to control who has what level of permission (read/write/modify) to the data & database. By default, the information being transmitted is not encrypted. As John Martin shows in this article, it is relatively easy for someone with access to a network (wireless access point or LAN connection) to read the unencrypted data that is being sent between a SQL server and client.

Definitely read the whole thing.  We’re at a point where the overhead cost of encrypting connections is low enough that there’s not much reason to leave production servers transmitting openly over the wire.
