Security :: Way To Protect Files From Download
Dec 17, 2010
I'm working on a website that streams audio files for the user from a directory on the server machine. How do I protect the audio files from users being able to navigate to the folder and just downloading them locally, but still provide them access to stream them? If I set permissions on the folder via IIS, is there a level that I can set so that the server can stream but not allow anonymous access?I'm sure there is a tutorial or other thread about this out there, it's just hard to search for this specific issue. Any help or a simple link to another thread/tutorial

I am new at asp sites, and just started to use visual studio...
So every page i make, there is another one (source file) linked to it.
Example...default.aspx and with that the default.aspx.vb or default.aspv.cs. I know what those files are for, but how do i protect them from being downloaded from users... Anyone can just type the url, and get my hard work :-/

I have a website running on a IIS 7.5 server with ASP.NET 4.0 on a shared host, but in full trust.
The site is a basic "file browser" that allows the visitors to login and have a list of files available to them displayed, and, obviously, download the files. The static files (mostly pdf files) are located in a sub folder on the site called data, e.g. http://example.com/data/...
The site uses ASP.NET form authentication.
My question is: How do I get the ASP.NET engine to handle the requests for the static files in the data folder, so that request for files are authenticated by ASP.NET, and users are not able to deep link to a file and grab files they are not allowed to have?

If a user clicked on a button, which runs a one minute process that MUST stay connected to the file (through the use of FileStream) for writing purpose, and he/she accidentally closed the browser. Currently, when that happens, if the user clicks on the button again, it will return an exception saying that the file is still being used. The part where I write to the file, the code for that is in a class library, which has a destructor (or finalizer, whichever), which calls a Dispose() method. It would usually take about 20 seconds before the file is free again to be used, but is there a way to make it quicker?
I'm thinking the way I'm designing my web app is not the conventional way. How do most people avoid this situation (ie. accidentally closing browser) where a file/resources are not freed up? Do they write into a SQL server instead of a flat file?

User downloads a document from a specified site, saves to the local disk and fills in confidential details. When other users logs on to this computer and if they try to access the file, the document should not be accessible. Also consider that the document can be saved to a common server too, in which case, no one else other than the person who downloaded and filled the document should be able to open the document.
some options to protect this document.

I have built an ASP.NET application that needs to be password protected. This application will be installed on multiple offline computers, and we need to make sure that when being installed it requires a password. But even if it requires a password, someone can easily copy the database and the published folder and duplicate the application on their system right?
I need a way to prevent this. It should only work on laptops that we have installed it on.

I have a website that is going on a public server so I want to password protect it, but for a while only myself and a couple of others will be using it. I will eventually get it together to do it right and have the users in a database etc, but for now, I just want to put a couple of users with their passwords in the web.config and have them authenticate on a login page.

I have a requirement to make parts of forms (and sometimes the entire form) read-only based on the user's active-directory group. I already have integrated AD into the dynamic menu, so that users cannot view certain menu itmes based on their AD group - and this is working fine; however, now they want to get down to the control-level on the forms. The first way that comes to mind is for me to just grab the AD groups for the users and then loop through them, and write my own code to make controls read-only or enabled. Is this a good way to do it, or is there another way? Also, while we're on the topic, is there an easy way to protect an entire form, or maybe an entire panel?

downloading files from an FTP server. The FTP server produces new files from time to time. so my application needs to Download only the "NEW" files and disregard what i have already downloaded previously. I have a time stamp on when was the last download time. I Using FtpWebRequest, WebRequestMethods.Ftp.ListDirectory, WebRequestMethods.Ftp.GetDateTimestamp. The problem is the ListDirectory gives me all the List in the FTP directory and i have to loop all the way down starting again from the start to the last file and check it with my last time stamp to DL the NEW files another problem is the FTP Directory contains 30,000 Files so it would take long until ill find the my last download time to start again on that point..
