Need To Secure Pdf Files
i currently have an asp authorization system setup on my website for access to certain html pages. this works great, but i need to restrict access to some pdf files as well. as of right now if the user is authenicated they have access to links to certain the pdf.
the problem is if i change a users access privileges they or anyone could open the file directly if they save or can guess the correct path.
i have tried to setup webserver folder security and use usernameassword@domain.com but this doesn't work in ie.
I thought about placing the pdfs in a database but im afraid that will slow down access to the files.

I need to be able to secure files on my web server. I am using asp to secure access to links and pages, for example:
<%If Session("manager")=FALSE Then%>
You are not authorized to view this page
<%Else%>
<<<Page Code>>>
<%End If%>
The place I'm running into problems is with files. I have a lot of charts and such in PDF version. I kind of doubt there is a way to secure these files with asp, but I thought it would be worth a try.
My biggest issue is that PDFs are stored in the browser's history, so once the page has been accessed, anyone using the browser can get to thatunsecured PDF. As a brute force fix, is there some way to simply erase the site from the browser history? If not, is there a way to secure the PDF, or does someone know of a better group to post on?

I may be in over my head on this one... VERY new to ASP. I have a potential client which is a marine loan broker. He wants an online credit application for the boat dealers he works with (20 different ones). He wants the credit app to be co-branded. Dealer/LoanCompany logos at the top would be sufficent. The dealer would have a link on there own site to the loan company's site but wants it to look like they are "Partners" and not just being shullde from one site to the next.
Is there a way to display different dealer logos based on the referrer URL? I would rather have one creditapp.asp that displays the proper logos depending on the referrer over building 20 creditapp.asp's. He doesn't need the form data written to a database. He just wants the form data emailed to him. (this I can do) How secure is that emailed data?

Right now, I'm trying to use WSH to run PSCP (command-line version of
PuTTY). I've tested the command I'm using by opening a DOS box
manually on the server, and the test file is successfully transferred.
I've run Filemon and Regmon while running my sample ASP page, and see
no permissions problems. I've tried running cmd.exe and passing PSCP
as the parameter.
I've tried running PSCP.exe directly. I've even
tried using ASPexec to run it instead of WSH. None of these have
worked. I always get the same thing -- error code 0 (success) returned
from WSH or ASPexec, but when I look at the second server the file
never got there, and when I look at terminal services on the Web server
PSCP is still running.

I have a website that we display images we have saved into a SQL Server 2000 database as binary BLOB. This is on a Windows 2003 Server. Just recently (a week ago) this website began to save the images it is displaying on the website as ASP pages in the Temporary Internet Files > IE.Content > Folder.
We have other websites where we use the exact same code and these do not save files on the server when they are displayed.
Here is the code to display the image:
Set rs = objConn.Execute( SQL )
Response.ContentType = "application/octet-stream"
Response.BinaryWrite rs("Product_Image")
SQL is the SQL String to get the image from database
When I add this code:
Response.ContentType = "image/jpeg"
The images still display on the website, but now are saved in the Temporary Internet Files folder as JPG's.

I need to secure my web page, when it is reading a file from the
physical folder.
Say for eg.. I have a page Page1.aspx, which displays a list of links
that corresponds to
the available text files in one of the files. All the other pages are
secured except this
page. So when I click the link, it redirects it to for eg..
http://localhost/folder1/one.txt.
But this should not happen. As the user can type this without even
logging into the website.
So I need to know how to stream this file and display it in another
page, rather than just showing it.

Here's what I/m doing to sanitize/validate/secure my input.
1. The front end checks what kind of data is entered.
2. I am using parameterized query instead of concatenated strings (Against XSS)
3. I am replacing symbols like <,>,# etc with their appropriate entity number eg. & #32; without the space. (Agains SQL Injection)

I have a client with their own W2k server and their IT guy refuses to turn on the SMTP service for fear of it becoming hijacked by spammers.
However, they also want their web site to perform some emailing functions I would normally use CDOSYS for.
I'm having them look into alternate SMTP servers to use with CDOSYS, but I was wondering if anyone here can recommend a 3rd-party ASP-based SMTP app that might be more secure than IIS' built-in service?

I have written a simple script that is called every 75 seconds or so to test whether the SQL Server database is running. The script is contained in a page that is not linked to in the site.
The thing is I have hard coded the database information on the page, I was thinking of putting the connectionstring into my global.asa file as an application variable.
How secure are the two options?
Will there be any performance issues? Bearing in mind that this page is called every 75 seconds.

I have set up an asp script which writes the output of a form to a database.I have achieved my database connection like this:Code:
DIM objConn
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _
Server.MapPath ("contact-2000.mdb") & ";User ID=admin"
objConn.Open
How do i go about making the database secure? at the moment anyone could view the source of the asp script and download the database.Which folder should the database be stored in? iv heard of using the root folder? at present the database is located in the same folder as my asp file.is there a way of setting up a password on the databas ein access and passing the password from my asp script to the database. the password would have to be encrypted though.

We have a need to allow our users to enter Credit Card #'s on a web page, so we need a secure page (have the little lock at the bottom of the browser) in order to do this.
1) What is this called? (I've heard the term SSL (Secure Socket Layer)tossed around, I don't know if this is the same or something different).
2) If I need a certificate of some sort for our server, how do I get it?

I have written a web app in asp3 which is used by lots of users.The data is all held server side.However,I want it so that the users can export the data in a csv file,much
like you can download a statement from online banking.
However,I don't want to save the file to the server,as then anyone else might guess the filename and download it.Is there any way to directly generate a file from an asp script.i.e.instead of asp returning html,it returns csv data which the user can save
away.

I have an ASP application that I would like to give out to customers. how do I control the licencing. They will get the source code.. (I know I can put it into a DLL - its a possibility) but even then they can simple copy it elsewhere.
So what I thought was some code looks at the servers name, IP and current date and generates a code based on that. Then, I create a code at my end that will only work for that server name, IP and up to a date I specify. The code would be encrypted somehow. Does that sound like it would work?

Is it safe to store credit card information in the ASP session state to be ultimately transmitted to VeriSign? I have a set of forms that are in the format of a wizard and I need to maintain the information through the pages. I know cookies are potentially unsafe, and I don't want to be responsible for credit card information being stored in my databases. I would use this type of method...
Code:
<% Session("CCNumber") = Request.Form("CCNumber") %>
If it helps, I have a VeriSign SSL certificate.

Are there any down sides to making the whole site jump to a secure layer from the word go? I have a site which does this from the point of login, but for people who don't login it stays in the normal zone. Just wondering about any possible side effects from making the default.asp jump straight into https unless it's there already.

I have a client who needs to be able to upload confidential documents (.doc and PDF) to a "hidden" area within their website so other members of their organization can later view them at their convenience. This area would be restricted by logins and passwords, but it also needs to be secure enough that no outsiders could gain access to these documents if they tried.
I've read on here about placing files in a directory outside of the root directory and then reading them back with a script but I'm wondering if there are other options that would be even more secure than this. Maybe with using some sort of file encryption or something else used in conjunction with files outside the root. I would be open to any 3rd party commercial software if someone has had good experience with it. Does anyone have suggestions to offer?

any good tutorial sites that could help me code a members area. In a nut shell what im planning to do is.
member login - 3 attempts at accessing members area.different access levels for different users. i also want to allow admin to upload files [word docs mainly] and allow the members to download them. I have previously built an asp login but it was very basic and had no security put in place.
if you know of more security features i need then please share the knowledge, it has been a while since i coded a dynamic site.
