Securing System
I recently developed my first website and I hosted it on my pc.But when I try to access it from other computers, I am able to do that only when I turned the firewall off.Is there any possibility to access my website in internet on providing security to my system?
And one more problem is when ever I access any control on my webpage in internet, I am getting a dailogue box indicating that "connecting to mysite.dnsalias.com" and it is asking for userid and password.If any one knows please tell me why I'm getting the dailogue box and how to avoid getting it.

I am currently developing a final year project which is a web based
tracking system tracking exam questions. I am using IIS as the
server, MS access for the database, and ASP with VBScript for the
scripting side of things.
One of the things I want to do would be to e-mail a user/moderator
whenever a exam question is edited/completed/updated. does anyone have
any previous expierence in this? i don't even know where to start.

What is the asp code variable for System Date and System Time? Are they built-in system variables, or is there some code involved to return the values?

How do I go about securing download files on my site so users can download those files only by clicking a link and not by typing the files address in the address bar. Is this even possible?...

I am wriging a web application which cosists of a main directory with all the main code, and a subdirectory with the administration features. althogh the two locations will share configuration resources, I need to protect the admin folder from unauthorised access. I know that in apache their is some kind of authentication (I think it is used through an ".htaccess" command or someting) and I'm wanting to do a similar thing in ASP.

Are there some easy to use (and free) web scanning tools that can check
for security vulnerabilities (SQL injection, cross site attacks) on classic
ASP apps and suggest ways to fix them?

Developed a web application which adopts a custom security model which displays a login page and requests a username/password combination. The username works in a mixed-mode of usernames matched with the windows login name and some extra accounts (similar to SQL mixed-mode security). Web application is executed both in the corporate intranet and externally on the web.
Getting user complaints about having to login to the web application when they have already logged-on to windows. I have coded a challenge/response (response.status=401) to get a user's window login through the ServerVariables. This seems to work OK for the intranet access. If the user's windows account is not located in the application database then I redirect to the standard login page for the username/password combination. When the application is executed across the internet through a firewall, the user is prompted by IE to enter the windows domain, username, and password. There seems to be no mechanism to avoid this because of the challenge/response code. I wish that with external access from the internet that users are automatically directed to the application login screen and not faced with the IE windows authentication dialog.
Anyone care to offer a solution?

I have a client who has a password protected page via session that lists a bunch of pdf's.They are a little worried that you are able to browse and see the pdf's via the url without being logged in.
I'm not sure if it's possible or not but is there a way after their username and passord is verified to automatically grant them permisson to view the contents of the pdf directory?

How can I make my asp page secure so that I can sell it and not have people be able to view the code. I know one way to do this would be to make it a component, but I dont really know how to convert ASP into Visual Basic.

I have a website setup which has MS-Access DB. The web pages are in ASP and uses ADO to connect to DB. The DB is located in the Folder "/Database". I have the Connection string setup in the Global.asa file.
As my virtual Directory is "/" and all files and folders including the "Database" folder are with in the folder so any one who knows the Database
folder name and database name can directly download the database from the
website.
The physical Directory for the virtual directory is: -
d:mywebsite
d:mywebsitedatabase
d:mywebsiteDLLs
d:mywebsiteimages
d:mywebsiteinclude
d:mywebsitestylesheet
d:mywebsite emplate
How Can I restrict the database to be access directly from web? Please suggest all alternatives that I can opt for.

tell me a way to programmatically with script at the server, reset the current user's security context from the IUSR_ account to a different one? what we'd do is anyone who is already logged in as a customer through our ASP page login setting customer-specific session variables.
we'd programmatically impersonate them as a different windows account,switching them from the anonymous IIS account they start off as. Bottom line is that we don't want them to have to login a 2nd time to get to these new pages. We've got other non-asp files that I cannot simply put behind an ASP-based login, which is why we need to lock the directory down behind Windows security.

My client has purchased 'software' - it really is just a series of html documents. I need to ensure that these pages are protected and only those who log in can view them.
I am building an asp/db based login front end to ensure that users have paid for the system. I just do not know how to protect the files from there because they are html. Converting them to asp is not an option.

I've learned how to basically access the database. Set ADOConn = Server.CreateObject ("ADODB.Connection")ADOConn.Open "myDataSource", "sa", "ItsASecret" But putting that code in each asp pages or putting it in the global.asa will be insecure. Since if the hacker gets the asp files or the global.asa files they will know the user id and password for the database. In this case, it's "sa" and "ItsASecret".
How can I do it so that they will never see this? I know of a way by using the Metabase.
if I'm not running my own IIS server to do that and that I'm just gonna rent a webspace what are their options? Will they let me change or add this in their metabase? If not, what's the term for securing it? How should I go about securing my database id and password?

all my ASP sites use an Access database. Most are parts of our company intranet and i want to protect the databases from being opened but have it so that i can open the tables and make adjustments if needed.
I've tried adding a password to the database but of course that prevents it from being accessed via ASP. Just wondered if anyone had come across this problem and found a viable solution.

Looking for a way to secure string. Have connect.asp page as an include file, but want to still use dsn-less connection and not have this in an asp page. Though about putting this in the global.asa file. Don't want to create a DSN and give IUSR_ rights to SQL DB.

I recently put together a site for a friend that needed a database to drive part of it. I tried and failed miserably at trying to learn ASP.NET & PHP so my friend sourced a web developer graduate who said he'd done a CMS for his final degree work. Great I thought, that takes care of the DB side of things.
On the back end, there are 4 web pages that deal with managing the database submissions:
1.) A login page
2.) A page to add a record to the database
3.) A page to delete a record from the database
4.) A page to update a record on the database
The login page has some sort of encryption within its ASP code but is not in protected directory so I guess it's probably subject to a brute force attack, but this I think my friend is prepared to live with as his site is so specialist and low-traffic. Code:

Firstly, apologies if this is the wrong section!
Ive created a site using ASP and an Access database. At the moment the database is unprotected, and I haven't used any usernames or passwords to access the database.
Now that development of the core site is almost complete, i want to secure the database.

I want to stick with VB on this project. The only problem I have with this is that I might have a problem with printing. The POS system is designed on a small 10-15 computer networked system. They are all good systems so nonone say that it may be a little to intensive for the systems.
Now once the system runs through basic checks: change exchange, enough money to pay, and other smaller features then it has to print the invoice. Now we have a small Epson Thermol (prints like Lazer) printer. How would my VB application send that information to the printer?

Microsoft, in one of its "Help & Support" pages on ADO, says that a System DSN is three times faster than a File DSN. I find that a bit odd for the simple reason that won't it be faster for a script to access a file to get info about the database source than access the same info from the registry which will be the case if a System DSN is used
instead of a File DSN?

I have been working on a simple eLeave System. I would like to get more advice of my db design. Basically, I have 2 tables here: user and leave_application. I will just put the relevant field needed for leave calculation.
user: date_employment, type, t_annual_entitled, t_annual_actual_taken, t_annual_balance
leave_application: date_leave_from, date_leave_to
There are 2 values under type, E - Executive and NE - Non-Executive.
Example
- If type = E, t_annual = 22
- If date_employment = 7 July 2005, t_workingdays = 187
- So, my formula for t_annual_entitled = (22 * 187) / 365
So, is my db design and my formula okay for this system? Any other better ways?

Created a basic ASP/ADO/Access 2000 Newsletter system using JMail.
Basically client has 300+ subscribers and wants to send 1 newsletter email
to them all every 1 - 2 months.
Missed my client's call to say it wasn't working, but having checked with my
ISP (FastHosts), they have some kind of embargo on the amount of emails that
can be sent every 10 seconds.
