  Tutorial: ASP Security Script Security Tutorial

This page offers lots of information and tips to protect your scripts against common attacks.

Tutorial Details:

Script Security

To protect your scripts, files, and databases, you need to ensure that the user entered data you are taking is legitimate. Users can pass strange data to try and crash your scripts, learn your database username and password, or vandalize your site. This article outlines simple techniques that you can use to prevent malicious users from messing with your scripts.

Request Method

I have seen many cases where programmers cut corners and use the generic Request() method to get their form data or query string data. This is not good for two reasons. One reason, not relating to security, is processing speed. The Request method contains ServerVariables , QueryString , Form , Cookies , and ClientCertificate . If you do not directly specify one, ASP will check ALL of them to see if the variable you are looking for is there.
