I'm just reading this:

http://www.sans.org/reading_room/whitepapers/vpns/1459.php

I few "interesting" things about this document. (E.g., there's a section 
called "what the heck is IPSec?" That's very whitty, but I'm not sure 
how seriously you should trust such a document...)

The basic premise seems to be that all VPN systems currently in 
existence actually suck, except OpenVPN which is completely perfect. A 
suspicious conclusion, obviously.

The document claims this is because "IPSec is too complicated to be 
secure", and that "TSL is mature and battle-tested". It also asserts 
that running software in user-space is inherantly better from a security 
perspective. (While it *is* better, it's hardly the end of the story...)

The document seems to indicate that installing IPSec VPN software on 
Windows is excrusiatingly difficult due to the built-in IPSec 
functionallity Windows already has. (...is does??) For example,

"On Windows, OpenVPN installs just like any other program. It comes 
bundled up as an executable and all you need to do it double click on 
the installer. Total installation of the Windows client takes about 10
minutes including configuration. For anyone who has tried to configure 
the builtin Windows IPSec client that should be impressive. For people 
who have tried to install and configure third party IPSec clients, that 
number should be shocking!"

Um... am I missing something? Installing Cisco's IPSec VPN involves... 
double-clicking the installer. And that's it. What's so hard about that?

Also amusing is the statement "Blowfish is a very strong algorithm with 
no known weaknesses. Its 128-bit key provides us with a large enough key 
space to make brute force key attacks impossible in polynomial time." 
Erm... like... WTF?

Still, I did learn one useful thing: Apparently the "route" command 
exists on Windoze.

I like how they make this assertion, then later on say "you might need 
the load balancing that IPsec does, but you can get that with OpenVPN by 
running this other complicated program on a spare machine." It sounds 
like a lot of the complication is stuff that OpenVPN basically leaves out.

Plus, I'm not really sure how they're running TLS over UDP, given that 
TLS is stream-oriented and assumes reliable delivery. It's also not real 
obvious from their descriptions that it's possible to run a UDP protocol 
over OpenVPN.

Ditto.

Of course, it hasn't been tested as furiously as AES, either.

Yup.

Well, is that a protocol feature or a software feature?

Hmm, that's a good point.

I was more amused by the statement that key size has any relationship to 
complexity class.

Blowfish is far more popular than, say, TEA or SQUARE or any number of 
other ciphers from the zoo of less-known algorithms out there. I note 
however that Blowfish has been "replaced" by Twofish which is meant to 
be stronger. (And AES finalist, I believe.)

A lot of people are apparently jumpy about the whole XSL attack thing on 
AES.

I'm saying that they mock IPsec for solving problems *they* don't have, 
because it was "designed by a committee".  I suspect the people on the 
"committee" actually *did* have those problems, so incorporated 
solutions to them into the standard, instead of making everyone solve it 
themselves with ad hoc solutions consisting of interacting layers which 
could easily introduce a security hole if you don't know what you're doing.

> I was more amused by the statement that key size has any relationship to 
> complexity class.

Yes, I understood the WTF. :-) Of course, if it's running over TLS, you 
can put whatever cipher both sides agree on in there.

And actually, key size *can* have a relationship to complexity class, 
perhaps. If you can pre-compute something that lets you look up in 
polynomial time the key that someone is using, except that the key is 
too long to store the precomputed somethings for every key, I can see 
where that can happen. (Technically, the same complexity class, but in 
practice, you can break something in polynomial time if you discount the 
precomputation, perhaps.)

But yeah, the whole discussion was full of WTFs like that. Plus, they 
say basically "IPSec is too complicated to deploy, OpenVPN does the same 
thing only its easy to deploy", without giving any evidence at all of 
either. Most of the paper is a description of SSL, and I'm pretty sure 
there aren't fundamental security problems with IPSec that aren't in SSL.

(And apparently the authors don't know that actual difference between 
SSL and TLS.  Hint: OpenVPN seems to use SSL.)

Hmm. I just wanted to know whether this piece of software was worth using.

I think I have my answer now...

Oh. I imagine if it solves the problem you have, it's probably worth 
using, assuming you can get it working and it's sufficiently widespread 
you trust it.

That the people writing the *paper* didn't write it in a convincing way 
doesn't really say much about the *code*.

It lead to a discussion in parliament here and a bad time for one of our 
ministers. Introduction of the country-wide OV chipcard (OV is the 
abbreviation for public transport) is postponed now.

At the last election in some cities voting was done again by paper and 
red pencil because somebody showed that you could listen to what people 
voted by putting a radio receiver close to it and a few more 
insecurities of the digital voting machines.

What these examples have in common is that they were badly designed and 
they relied on people not knowing the details as an important security 
measure. The latter is of course an absolute sin in cryptography, but 
apparently not (yet) when designing voting equipment or identification 
cards.

Security through obscurity = hmm, it doesn't work. ;-)

True. But given that it seems to be a one man project... Well I'm sure 
it *works*, but that's not the same as being secure. [Not that any sane 
person is going to bother trying to hack my systems unless it's 
sufficiently easy.]

I see. I hadn't followed it up.  No, if the author of the code is the

It appears the report was written by somebody other than the author. But 
then, comments like "OpenVPN seems to be using SSL" make me suspicious. 
As does the fact that SSL and TLS both run over TCP, yet OpenVPN seems 
to be using UPD. That looks like a big enough deviation from the 
standard that I'm left wondering how many design decisions have been 
made with potential security implications.

It's not like OpenVPN just calls the OpenSSH crypto library to do its 
bidding; it looks like a complete new implementation.

That sentence made me laugh.  Of course, it's 3 AM here (almost 3:30), so 
I'm a little sleepy, but can I just say THANK YOU?  I *really* needed a 
laugh.

Tough night, and this really helped.

Thank you.

Seriously, Zazzle boasts that you can have your order within 24 hours,

Ah, I see.  There are so many Jamies' in the world.  But hey, it sounds

Seems a lot of companies operate that way.  We have a similar experience 
when ordering DVDs from amazon.co.uk as well.

And not just DVDs (hit send too soon).  Just got a copy of the Uxbridge 
English Dictionary, and it (actually surprisingly because we ordered from 
a US site) also was sent via Royal Mail from the UK.

Meh. There are people I sometimes speak to on teh interwebs. But human

Yes, exactly. That, and all the other things you might want to do (like 
be behind a NAT) that OpenVPN doesn't handle.

Note that SSL and TLS are both technologically the same thing. The 
difference is in provisioning. That is, it's SSL if you start the 
protocol dance as soon as you open the port (because you're talking on 
port 443 instead of port 80, for example). It's TLS if you open the 
connection, do some negotiation, *then* start encrypting, such as with 
BEEP or Secure SMTP or anything else that has a "STARTTLS" command.

I thought I saw somewhere that OpenVPN *does* work with NAT, but IPSec 
doesn't. (Because NAT involves packet modification, which IPSec is 
obviously designed to prevent.)

No, what they said was that if you want IPSec to work with NAT, you had 
to exclude the IP addresses from the hash calculation with a 
configuration. Since OpenVPN never even offers the opportunity to 
include the IP addresses, it's "simpler" and therefore more secure.

Huh?

IPSec can work over NATted connections, you just need a router that will 
handle it.  The last couple Linksys routers I've had (and the Belkin I 
currently own, IIRC) have supported IPSec over NAT.

Hey, the same goes here.  Offhand, I can think of about 2 people outside 
of work that I will just hang out with - and they're my immediate 
family.  I'll occasionally have lunch with one of my instructors or 
coworkers at lunch.  Very occasionally, I'll get together with the 
neighbors across the alley from us, or the ones next door to us.

You're not in the US ordering from a.co.uk, though.  When I order from 
Amazon US, delivery time is just fine - but from the UK, it takes a while 
longer.

Heh, well, I know a number of Brits who celebrate having rid themselves 
of us, so that's fair. ;-)  As for us, we celebrated by calming cats 
during the fireworks - but the fireworks themselves have been very muted 
this year out here.

Oh, and I cooked us some *excellent* steaks.  I managed - for the first 
time - to cook medium-rare steaks instead of cooking them until they were 
charcoal.  You'd be able to see more about it in my LJ.

It's kinda ironic - I'm perfectly happy having some reheated pizza or 
canned soup, but I somehow do seem to pull together some pretty good home 
cooked food every once in a while - and I enjoy it, which just really 
surprises me.

Be careful about generalizations.  There are quite a few of us who do

I have used both the UK and the USA ones and it does work. Presumably if 
you order something from .com you get a box with .uk on it anyway. At 
least when I order something at .uk I always get packages from .de even 
when the item is not listed at .de

More to the point: apparently I have to sign up for a new, seperate

I did say "typically". I'm sure there are plenty of Americans who know 
more geography them me. (Wouldn't be hard, would it?) But unless it's 
just the policy of my particular company to only hire stupid people, 
most of them seem to interlectually comprehend the fact that the UK 
isn't the USA, but on a practical level forget this fact at every 
possible juncture.

Well I've just got an oven back so I'll be able to return to home-cooked

Strange, using a wok in an oven :)

I must admit that home cooked food is just about all I eat. Except for breakfast
and when I have to eat out.

Does great roast potatoes. Heh no a shiny new hob to match the oven.

Ditto. I'll nuke the odd meal if I know I'm going to be running around or  
get a pizza or something in if I'm just feeling lazy (way too many  
takeaways around here), but the majority of my meals are home-cooked.

You should see where I live, two Caribbean take-a-ways, three Chinese, six
Iranian/Iraqi/Persian, one African restaurant and a really good fish and chip
shop. All within ten minutes walk. But to counter that we have lots of
Caribbean, Iranian and Chinese food shops as well. Oh! I forgot about the Indian
restaurants and the English butcher.

Well we don't have the variety, but four chippies, two Indian restaurants,  
three Chinese, and two pizza/kebab houses; plus the Subway and three other  
sandwich shops and four independent butchers. Plus the caff, a tea shop  
and a cross between a restaurant and a tea room; the cake shop and the  
sweet shop. Oh I'm not counting pub food that would be another  
three/fourish depending on who you count and how far out you go. Come the  
renovations in town they're expecting coffee shops and more tea shops.

It amazes me how many companies don't understand the idea of identity 
management.  I work with a company on course evaluations and I have 3 or 
4 different logins for different "roles".  I should go work for them and 
show them how to manage the identities - would make it so much easier for 
their customers.

Sorry, were you talking? ;-)  (Just kidding)

Well, I don't know where your company's offices are here in the US or how 
widespread they are, nor do I know how big your location is in the UK.  I 
worked once for a company that was headquartered in Austria - never 
actually did have any dealings with people in that office, but we were 
run *mostly* independently of the parent, too.  I think in the 3 years I 
worked there, my boss made 2 trips to Austria and Germany.  I never knew 
anything about their infrastructure at all, other than that they had an 
AS/400 of some sort.

Before you put oil in the pan, a quick touch of the surface will tell 
you if it's hot enough. Don't do it after you put oil in the pan, 
though.. that'll land you squarely in the burn ward.

An IR thermometer will also tell you if it's hot enough or not - and 
won't even singe your fingers. :-)
