RE: Protecting posted variables

["Andrew Chong" <andrewjw () singnet com sg>]

The industry best practice is to use SSL to encrypt the transport layer.

No rocket science and no further applications codings. Another custom
encryption will add-on to another keys management issue.

Subject: Protecting posted variables


Hey all,

A 'fixing the problem question'...

Outside of encrypting in SSL, how can variables being posted from the
browser back to the server be protected from prying eyes?

During previous pentests, I've seen variables being posted to a
webserver (IIS6.0 is  one I remember this with) all hashed together. I
don't think that any special client-side software was used, it was a
function of the site....

Can anyone help in identifying what it was that I saw in operation? -
The only solution I can see is that it was the AspKeepSessionIDSecure
Metabase Property 

(ref:http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Libr
ary/IIS/0d49cbc8-10e1-4fa8-ba61-c34e524a3ae6.mspx?mfr=true)

with the variables posted in with the sessionid?

Also, is this type of solution available in any other webserver?

Any help gratefully recieved...

Thanks..
