Hi

Hope somebody in this group can educate us to see if
there is any better solution or implementation to this
situation.

Scenario
========
We have around 50-75 ASPx pages (.NET 1.1 framework),
and it's a very simple WEB application. Each of these
pages does only data-in and data-out, so far nothing
complicated.

Requirement
===========
We want to implement XSite scripting, Malicious TAG
Check, SQL Injection validation in this site.  

Solution We Proposed
====================
We opted to crate an XML file which stores list of all
the Malicious TEXTs (see example below).  If user
inputs any of these texts (the ones within the <TAG>
node), we will STOP/Alert the user from submitting the
page.

Question
========
1. How do I implement the "validation check" in each
of these 50 pages in a fast way, so that I dont need
to change too much of code.  Is it possible?

2. How do I ensure that if a new page gets created,
this feature gets implemented magically.

ThreatModel.XML
===============
<MaliciousTags>
   <XSitetags>
      <TAG>script<TAG>
      <TAG>object<TAG>
   </XSitetags>
   <SQLTags>
      <TAG>DROP<TAG>
      <TAG>DBCC<TAG>
   </SQLTags>
</MaliciousTags>

Thanks
PP
