Except the approach of a bot trying known exploits is automated. It doesn't take any effort of the hacker's time. It's not on his machine so doesn't even use his resources (time/CPU/bandwidth). It doesn't even need to check what software is running, simply trying everything in the book is sufficient. And that could be done in a couple of minutes.

So, "security by obscurity" is working, not so good, but thousands of years.

Actually I'd argue the opposite. Security through obscurity often makes people assume they're secure and therefore neglect securing their systems in the places that actually matter.

The only argument I can really see of hiding that you're running $version of $product is that an bug in that $version means an exploit exists.

If that's the case then you need to upgrade to a patched copy of $product - you can NOT rely on the fact that people will not realise that they can use the exploit because you're hiding what you're running.

The flaw still exists and attackers might either a) guess you're using $product and try the exploit anyway or b) have their bot just randomly try every exploit in the book against you until one works in which case they don't even need to know you're using $product.

The things that matte are actually verifying your authentication is working correctly, you're running the latest software, you're following software updates / security announcements, etc.

Besides even when $product/$version are hidden they can often be found through fingerprinting by looking at differing behaviour between different products and within a product between versions.

I think we need to drop into the real world...

1) Ok .,... Don't forget to say thanks to Debian , CentOs , Fedora , PHP , Python , Microsoft , all the authors of the OpenSource Libs , the creator of Make , the creator of the IDE that the Dev team uses ,  etc etc when you deliver the next project to your client ...

I could also imagine you agree with showing the version of the software in the HTPP headers (stuff that happens on some webservers/libs ( from my ming i can recall Django?!).

3)
The clients pays it doesn't really care about what software you use ( unless he fears some patent infringement) he wants results.

4)
No , Compliance could be internal or external the end-client could simply say "i don't want the freeswitch brand".

@all
I don't know you guys but my daily work is developing software for some fairly large financial institutions and sincerely i think you are all over reacting to this thing.
Yes if you open-source something you will get part of your software stolen , changed or use in a way you were not expecting and not given credit for , that's life .If you don't want it , close the source , resell it , ask for NDA's , etc.
In my daily work me and my collegues use alot of open source ( contrary to the popular belief) , closed source and everything in between and you don't expect a public statement thanking anyone for anything.

This is the way life works and with open-source this is our current world ( i think the FS Team could even offer a fully custom branded solution) so it could help monetize the project.

And before you start thinking yes i bought G729 licenses , the FS Book even before it was out and no to many miles between me and Gluecon , yes i know airplanes exist :D.

P.S - I Also assume that you all as sysadmins once found a problem that a blogger may have solved and on your final report to the administration you didn't wrote " problem solved by Blogger XXXXXX"....

And never forget he is just the mailman sometimes the boss wants something ( even if not morally correct ) and you have to do it.
But the point raised by Anthony regarding the SDP "freeswitch flag" is important and you be featured on the wiki :)

Ok... Lets look at these...

Branding... I don't want to show people that I'm using F/OSS software for
running my for profit business so I can tell them I'm using either
${some_comercial_platform} or ${we_developed_this_ourselves}

Security/Security Requirements - Security throught obscurity != security...

Client Requirements - That's a new one one... Unless client is <see
branding>

Compliance - isnt this the same thing as see security
