Hi I am new to asp.net and have now built my first site.
I just want to check if I should encrypt the connection strings. I looked into this when I first started but could not get it working (cannot remember why now). I noticed that i can not view the web.config file so thought no one else would.

But I just wanted to know if it is possible for other to see it and if so blockit or encrypt it.

It's possible for whoever has authorization for the folder where you web.config resides to view the file. Typically, this would only be admins for the machine in question. Ask yourself who will have direct access to the machine and its filesystem, and also what could happen if someone gain unauthorized access to your machine and its filesystem. That might help you decide whether or not to encrypt the web.config.

Hi Thanks the web.config is in the root directory, which is where the default.aspx file is. If i try and view the file through a web browser I can not see it. I get an error saying
"The requested filtering module is configured to deny a path to the URL"

As I am the only person with access to the server and the only admin is it that important. As long as no one on the www can see it and change the database I dont see it being a problem?

That is correct. By default, and as a security measure, web.config files are not served. You should not copy them to the website directory, but your code-behind files also would not be served if you deploy them to the web server. There are a couple of other files which are not served (I believe global.asax is one), but I cannot remember all of them. I'm sure they'd come up on a quick internet search.
