HotIce -> Q. Signature Filtering Through HTTP (29.Aug.2009 11:01:03 PM)

Hi... Im using ISA 2006, and if I want to block specific keyword, Im doing it through HTTP Filtering using Signatures. Im just wondering if I am correct in using this type of setup. Any idea??? But still it works.. The only problem I am encoutering is that, when I want to block the keywords, like "anal", "adult", it seems that the word "analysis", "adultery", which is not to suppose to be block, is also blocked.

Example1
Signature Name : porn-adult
Signature Search Criteria : Request URL
Signaure to block : adult

Example2
Signature Name : porn-anal
Signature Search Criteria : Request URL
Signaure to block : anal

My objective in here is to block those keywords from accessing it by every clients connected to my network, and its blocked by ISA 2006 using the configuration above, but the words "analysis" and "adultery" is also blocked.

What should I do..?

Thanks you.. I really needed your reply.

Well, If you use HTTP filter to block web sites this is bound to happen.
You would be better of using ISA add-ons that are outlined here
http://www.isaserver.org/software/ISA/Content-Security/
GFI WebMon is my favorite.

If you are using ISA Standard edition this is also handy
