Re: WAF functionality ala OWASP London Meeting

... what?

the WAF is set up at the server side, so the request has already been
sent and received. Too late for the WAF to say "well I won't deliver
this to the page, as it's visible in the URL ..."

Or do you mean to stop GET for some other reason?

Or are you asking the WAF to re-write the html presented by the
webserver so that <form method="get"> becomes <form method="post">
where action="authenticationPage" ?

Hello WAF Vendors,

After discussing this with Dinis (Mr Cruz).......

Is there any way to disable HTTP GET requests for authentication pages
in any of the current application security firewall offerings?

Many applications I review accepts authentication via GET and POST, I don't
want GET to work, can you of the cu rent firewalls prevent certain
HTTP methods for particular URL's  (context sensitive rules)???

To make things a little more difficult,

In the case of .NET, postbacks would be used also so its not always as
simple as blocking a URL with a certain HTTP method, as the home page
URL may be the same as the "submission" URL.

What direction  would your App Layer firewalls go to solve this
problem. Many vendors say "don't trust developers, use our product
instead", well OK I wont trust the developer here, can any of your
tools do this?

Thanks,
Eoin
