[ACFUG Discuss] Blocking a ColdFusion website's directory
Hey Everyone, I am currently in the process of building my first secured site. Most pages of the site will be behind a login page. I'm using ColdFusion's Application.cfc onRequestStart function to check if a user is logged in or not. Thats pretty much boiler plate. My concern is how to prevent an non authorized user from accessing or hotlinking to non ColdFusion page. (i.e, images, pdfs, swfs, .txt etc). Whats the best way to ensure a user can't link directly to these items but instead be redirected to login.cfm instead? Is there a way to lock down an entire directory?

Re: [ACFUG Discuss] Blocking a ColdFusion website's directory
For things like that I normally store them outside the webroot and then serve them via a cfcontent in a cfm script. Instead of a link like http://mysite/mypdf.pdf it would be http://mysite/getfile.cfm?var=myfile.pdf. That is very oversimplified, but captures the approach.

How does that work when you are serving a direct like to a PDF or a DOC? CF has nothing to do with that.

For example, in some include file or function, you could use a statement similar to this: cfif not session.loggedIn cflocation template=”login.cfm” /cfif If the existence of variable “loggedIn” is not present, the user will be redirected to the location you determine.

Re: re[2]: [ACFUG Discuss] Blocking a ColdFusion website's directory
Mischa, Yes, but as you can see from Shawn's comment that Shawn was approaching the topic from the point of authorization. From the response by Troy, this leads to authentication. So, his usage of diction or use of the word is indeed correct, but not everyone interpreted it that way as it still provided some confusion regardless. The solution may very well use both concepts to achieve his desired result. A use that I have witnessed has to deal with Shawn's suggestion of putting the files in a non-webroot accessible directory or network source. Then a controller mechanism would have to understand how to serve once either through a mechanism of of being an authenticated user with an authorized role of being able to see a document. Or, the the site does not have authentication and the mechanism must have a more introspective ability to discern a user through their token, IP or whatever. The public approach would suggest a tracking process to see if a particular requestor has asked for the document before or not. This also brings up the question, how do you determine who has the authorization to request a particular artifact multiple times? This may be over complicating his initial scope of the application, but these are questions that I would ask whenever someone would task me with a File serving application on potentially limited released documents. In any event, I was not criticizing Emile. I was asking for more detail before offering generic advice/guidance. Teddy R.

RE: re[2]: [ACFUG Discuss] Blocking a ColdFusion website's directory
Emile, the sandbox features are for protecting what files/dirs a CFML app can access. It's intended to be used on a server where different developers of different apps (on the same box) should not be able to access each other's files, or files outside their purview. BTW, it's called Sandbox Security in Enterprise, but it's called Resource Security on CF Standard. I've done a pair of articles on the topic in the Adobe DevCenter (from the CFMX timeframe, but it's still applicable): http://www.adobe.com/devnet/security/articles/sandbox_01.html http://www.adobe.com/devnet/security/articles/sandbox_02.html Hope that helps. /charlie From: ad...@acfug.org [mailto:ad...@acfug.org] On Behalf Of Emile Melbourne Sent: Thursday, December 18, 2008 5:24 PM To: discussion@acfug.org Subject: Re: re[2]: [ACFUG Discuss] Blocking a ColdFusion website's directory snip Shawn, what is the purpose of the files and directory settings in the Sandbox?

RE: [ACFUG Discuss] Blocking a ColdFusion website's directory
Emile, if your site is running on IIS, another idea would be to use the .NET framework to secure the directories. You can find discussions in various .net articles/books/blogs. Here's one simplistic discussion from MS: http://support.microsoft.com/kb/893662 People don't tend to think of this because they think my code is in CF. But the whole point of this discussion is that you're talking about accessing non-CF files, and therefore can consider solutions that are not CF-based. Shawn's idea of CFCONTENT is of course a way to bring it back to CF's purview. It kind of all depends on what authentication mechanism you want to use: one under CF's control, or one you'd be willing to let be managed by something else (whether the CF, the web server or the .NET framework managing it, and whether-in the latter 2-your're using windows forms, passport, or windows authentication).

My concern is how to prevent an non authorized user from accessing or hotlinking to non ColdFusion page. (i.e, images, pdfs, swfs, .txt etc). Whats the best way to ensure a user can't link directly to these items but instead be redirected to login.cfm instead? Is there a way to lock down an entire directory?
