form security against security
i have a form in my website which is to be filled by user and that form stores in database(sql server 2005).
but someone told me that anyone can run script in textboxes in that form and can damage database,
so how to avoid such security lack.

it is common practice to use parameterized sql statements or stored procs to insure you are protected from sql injections attacks.
if you concatenate user input directly into a sql statement, then you are at risk.

when is secure, secure?
Lo everyone, I wrote a custom authentication handler for PureFTPD, using a combination of authentication methods, for about 4 different types of users. So far, from testing it, it does look to work properly, and does it's job pretty well (and fast). I use #!/usr/bin/perl -W as well as use Strict, and use warnings, and the code returns no errors or warnings when run. I am right to presume that this basically only really tells me the my syntax and structure of the application is right? What's a good way to see whether it is actually SECURE...

Thanks to this group and all the high tech individuals who frequent it I have learned how to protect my PC from the inside out.

Any security issues using Impersonation along with Forms Authentication with Integrated Security (SQL SERVER 2000)?
I currently running a ASP.NET application (Visual studio 2003) with SQL Server 2000. For security I am using forms authentication and integrity security for sql server enabling the ASP.NET account. I am developing a module that create, delete and upload files on a network directory. If I set impersonation in the web config to true and specify a username/password will that conflict with my current security? Would it be better to make impersonation specific to this page? Any ideas on the approach? Thanks ...
Replacing SQL Integrated security by Custom security
ClassifiedsSK required the most basic security (probably just two roles -guest and admin- for most of us) therefore I would like to eliminate the SQL Integrated security (which adds more SQL objects than the logic of the app itself) for a very basic custom security (login and password in the member table, plus a simple role table -or even a "IsAdmin" indicator within the member table- would do the trick). Now my question: Has anybody done this already? If so, would that person be willing to share the code? Thanks in advance. GP...

Password secure...is it secure?
Yes I just got this baby and I LOVE it! Its great. I have stored all my passwords inside of it (and yes made a few backups from them in secure locations) How secure is this program really? It uses blowfish to encrypt the database but how strong blowfish? 128bits? 256? 448? Anything else I should think about it? I have putted it and its databases inside PGPdisk just to play it safe...but then again Im a paranoid. :) -- Markus Jansson ************************************ My privacy related homepage and PGP keys: http://www.geocities.com/jansson_markus/ ********...

Secure connections: how secure are they?
*QUOTE* ......... both useful and malicious information can be transmitted via network connections. Standard solutions protect computers against threats present in standard network connections, but aren't able to counter threats present in secure connections. Verifying the contents of a secure connection is impossible by virtue of its secure nature, as demonstrated by the different types of protection listed above. As a result, malicious data within secure channels can cause a significant amount of damage, and sometimes more than if it were to be transmitted via a standard, non-s...

File security from web-apps with Forms security enabled?
I am developing a series of web-apps, in the process of converting older client-server FoxPro apps. We are forced to use Forms-level security on our web-apps, due to licensing issues with providing Active Directory Windows-base security, and have adopted the ASP.NET 2.0 security schema. However, I have ran into a problem because many of our applications use sensitive Word and Excel attachments to the plans we store in the SQL Server 2000 and 2005 databases. Forms security adequately protects the web-site pages and the database data but when it comes to protecting access to ...
