I have the following connection string:
Data Source=Paul-HP\\MYDB;Initial Catalog=MyMSDBSQL;Persist Security Info=True;User ID=sa;Password=password >
Data Source=Paul-HP\\MYDB;Initial Catalog=MyMSDBSQL;Persist Security Info=True;User ID=sa;Password=password
Probably easiest to encrypt the connection strings within the web.config or app.config
