@xce Heh, indepth cryptoanalysis of specific algorithms is the one thing which i'm not yet prepared to learn. It really is difficult to wrap your head around the math.

Q: Vote for your question of the week #32

Rory AlsopFor QotW #32, scheduled for publishing to the Security Stack Exchange Blog on 3 August, please post as Answers, and vote for your favorite question from the whole Security Stackexchange site. Please post any question that you feel is of worth and the reason why as an answer below. Try not to pro...

I'll be camping for a few days and while the campsite may have internet connectivity, I'm not going to try and write a blog post on my blackberry :-)
I don't mind giving it a shot. When is it due though? I'm pretty busy this couple of days.
@TerryChia Well, while we call it Question of the Week, sometimes we have taken a while over it :-)
I am happy to add you as a contributor on the blog - and what we do is draft the post then let someone else on here review, before publishing on Friday
It's a standard Wordpress site, so I'm guessing you will find it all pretty straightforward
09:20
I got the invite. I'll draft something up in these couple of days. :)
@RoryAlsop where's the dedication Rory? jeeez :p
Time to collect some badges here too

@LucasKauffman Well, I was supposed to be on holiday last week, and still ended up working too much, so I'm going somewhere with no power so I physically can not be asked to work. Love my job, but sometimes I do still like to have a holiday
@RoryAlsop then don't even take your BB, just get a dumb phone otherwise you'll still end up reading emails
@LucasKauffman It looks like I do need to make a few calls, and review a couple of documents this week...plus, I still need to check mod messages here :-)
@LucasKauffman Yay - you got 10k on SF! Congrats
10:23
@RoryAlsop No no, no you don't - me and @Hennrik will cover for your lazy arse! cuz you know, you dont really do much over here anyway, right... ?
actually, I'm starting to be back online more often now, now that I have a proper home office :)
though it does make it "easier" to seperate between family and work...
10:38
@AviD :-)
It is sometimes needed - my home office door shut means I am on a conf call or otherwise not to be disturbed
@RoryAlsop well, my problem is the other way around - now, since my office is aaaalll the way downstairs, if I surface up for dinner, or bedtimes, I find it difficult to make the trek back down.
not to mention it's quite lonely there at night.
heck, I think I worked only one night since I've moved. No idea if that's good or bad.
aww, this is sad. Mcafee really hates security...
Since shortly after they acquired Foundstone, there hasnt been a single update to their once-awesome set of security tools since 2006.

@AviD Feature. Complete. wipes hands
153 rep today so far. Sweet, i broke my previous record of 120.
@LucasKauffman caused me another Enlightened badge by posting an answer 1min before i posted mine, just as I was typing it out. :P

why does the defcon site use 403 instead of 404? :/
xce
xce
13:19
what do you think of cryptocat? there is a lot of news about it recertly
The Web server (running the Web site) thinks that the HTTP data stream sent by the client was correct, but access to the resource identified by the URL is forbidden for some reason.

This indicates a fundamental access problem, which may be difficult to resolve because the HTTP protocol allows the Web server to give this response without providing any reason at all. So the 403 error is equivalent to a blanket 'NO' by the Web server - with no further discussion allowed.
xce
xce
Oh so it's totally ok to use 403 instead of 404, but most sites don't do it
Well, the difference is that 404 is: the HTTP standard response code indicating that the client was able to communicate with the server, but the server could not find what was requested.
so it's that difference between forbidden and not found
xce
xce
I see
but I would imagine you can always use a 403 rather than give back any information about what files exist
13:30
That and 403 matches more strongly with the Security Troll stereotype than a 404 does.
13:43
Is the 200 rep per day cap still in place?
Yes, but reputation earned from bounties, accepted answers, accepting answers, and from accepted edits (if you're below the editing priv) don't count towards the rep cap.
Ah i see. Great, i maxed out my rep cap for today at 203.

> “If someone wants to compromise a Skype communication, all they have to do is hack the endpoint — the person’s computer or tablet or mobile phone, which is very easy to do,” said Tom Kellermann, vice president of cybersecurity for Trend Micro, a cloud security company.
.. is it?
what does "The authorities long have been able to wiretap Skype calls to traditional phones." mean?
I was trying to understand this washingtonpost.com/business/economy/…
@xce It means if you call a landline with Skype, the spooks are listening.

A: Do secure phone lines exist?

Thomas PorninA secure phone line is conceptually possible; this is not really different from, e.g., a secure communication between a Web browser and a HTTPS server (there are technical subtleties about lost packets and whether they should be tolerated, but that is not the issue here). However, the movie-secur...

In short: If you have to ask "Is this line secure?" then it's not.

I wonder what would happen if a people started using a secure open protocol instead of skype?
they can't really ban cryptography because of HTTPS
hey why is your phone red?

Q: How to secure passwords when site is opensource

jcubicHow can I store passwords to have them secure? Right now the site use md5 md5, I was thinking about sha1+salt but if the source code for the site will be open source (I'm rewriting the site and the code will be on gihub) everybody will know what the salt is. So how can I secure passwords so they...

Have @AviD or @RoryAlsop close the question as a duplicate and possibly merge your answers with an existing question.
I really wonder how he managed to gain 3.8k rep on SO.
@TerryChia Indeed. Which question do you propose is duplicate? There's a lot of links in there.
I flagged the question as a duplicate of security.stackexchange.com/questions/211/…
It really covers a lot of questions though. It really is too broad to answer in its current state imo.
@TerryChia Oh? I didn't see the close flag. You must not have close vote privs?
@Iszi Yeah, 3k priv to close vote. Still a long way from there.
15:29
I'm not sure the suggested duplicate is really a duplicate.
This question seems to be screwed up in its own, special way really.
Perhaps close it as not constructive?
The gist of the question "So how can I secure passwords so they will not be easy cracked when the database leak? Any ideas?" is covered by the "how to securely hash passwords link"
The question also seems to be "What security measures should be taken when the password hashing mechanism and salt are open source?".
(The answer to which is: You're doing it wrong.)
On a more amusing note. Some images that fairly well express how I feel...
Yeah, I don't get why the site is open sourced. Sure, the framework of it could be open sourced, but the exact implementation and configurations shouldn't be.
That cluebat one is good.
In other news, I'm still surprised that my answer for this question got 22 upvotes.

Q: "Username and/or Password Invalid" - Why do websites show this kind of message instead of informing the user which one was wrong?

bobble14988Lets say a user is logging into a typical site, entering their username and password, and they mistype one of their inputs. I have noticed that most, if not all, sites show the same message (something along the lines of, "Invalid username or password") despite only one input being wrong. To me, ...

15:40
@TerryChia 23 now. I'm actually a bit surprised we don't have anyone that's gone further in-depth with it.
Yeah. I wrote that answer in like 3 minutes while listening to one of my lecturers speak. The voting system is weird sometimes.
Okay. I think I've hit my limit. Check the comment thread on that question, and my answer, now.
@RoryAlsop @AviD Where's the "OP doesn't have a clue" close reason when you need it?
facepalm
even if it is open source it shouldnt matter if its written properly
@LucasKauffman If you wanna try talking some sense to him, feel free. I'm done.
15:48
@LucasKauffman Configurations should NOT be open sourced. The code itself can be, but the configurations definitely shouldn't.
I need 1 more vote on my answer for a new shiny silver badge.
School should reward good answers with badges. They motivated me more than grades.
@TerryChia This point is arguable. In a proper crypto implementation, the only thing that should be secret by necessity is the key.
@Iszi The issue is that it isn't entirely about the crypto implementation. Website configurations like database names, passwords etc should not be made public. To do so is just asking for trouble.
The question isn't asking about an open sourced crypto system, but an open sourced website.

@TerryChia I'm not talking about configuration details, but it's a website, what about Wordpress or Drupal, tons of the configuration is open source as well
obviously the passwords and DB names shouldn't be made public
but he's just asking for the salt
(he also doesn't have a clue how to use a salt)
Take a small pinch and sprinkle it lightly over the food.

Hello people
19:20
@ThomasPornin grrrrowll!
It is quiet here
People are on holiday ^
?
19:33
@ThomasPornin I wish
I have been away from the *.stackexchange sites for a few months. Anything worth mentioning has happened ?
19:50
@ThomasPornin Hey! We've missed you! What hole did you fall into?
@Iszi I switched jobs
much less free time now
and there is a firewall (this one is a non-issue as of yesterday, though)
@ThomasPornin Ah. You think that's just a transitional thing, or are you seriously crammed now?
@Iszi I am now a consultant, with time-based billing
Ah.
I cannot stretch my working hours as I did before
I will see how things go in the next weeks, now that I have a decent browser and a non-filtered connection
20:01
@ThomasPornin What happened? They let you bring in your own laptop & cellular hotspot?
@Iszi I could do that, but it might be expensive
Actually, it turns out that the port 443 is not filtered
so I setup a RDP server on a Linux server which I rent
on port 443
with some magic gimmickery on the server because there is also an Apache running on that server on the same port
I am using it right now; full-page scrolling is kind of painful, for a RDP which goes across the Ocean
20:14
Sounds like loads of fun...
Bummer about that firewall. What's their excuse for disallowing *.stackexchange.com?
HERRO PEEPZ
you are my new home now, I changed my main account to sec.SE :o
@LucasKauffman Welcome to the partay! What was it before?
serverfault :)
Ah, kewl.
but since I joined the security professionals, I should change me main account :p
20:18
@Iszi It is not really an excuse
@LucasKauffman Now you just need to sort out the rep difference. We'll give you a week to catch up on 6,554 rep points.
There is a firewall which blocks many sites which look bloggy-chatty
...and the rest of the month to double it.
and then, the Web browser is IE7, which does not work well with stackexchange
20:19
@ThomasPornin 7? Yow.
@Iszi Indeed. Kind of crashy.
I am not allowed to install new software, but the rdesktop client is already there.
@ThomasPornin Heh. You've got physical access, but you're not "allowed" to install new software. Hehe...
Running a portable app isn't technically installing new soft...
20:24
Wow. I did an image search for "evil grin". Not a whole lot of real winners there, but this kid looks possessed!
@Iszi It is a devious security scheme, which works on the user being honest
2
o.O
@ThomasPornin naivity
@LucasKauffman Formally, there is no rule about not running executables which are on a USB key. As long as I do not copy them to the local harddisk.
However, there are explicit rules about meddling with the proxy settings.
@ThomasPornin Arguably, I'm sure you could copy them to the hard disk, as long as it's in your user profile.
20:30
With rdesktop, I can at least pretend that the local system is not undangered.
endangered ?
yeah, maybe endangered, not undangered.
@ThomasPornin virtual machine?
@Gilles I am not sure there is a VM implementation which can run off a USB key with no local installation and no Administrator rights (on a WinXP system). Also, the firewall would still block me.
I do use the software-on-USB-key trick to run GVim
@ThomasPornin I think you can run VirtualBox that way, but without using any of the processor virtualization extensions
for firewalls, there's tunnels
@ThomasPornin Whoah... IE 7 and XP? Gross!
@Iszi that's what I have at work (or is it IE6?). Fortunately, we have no prohibition on installing software
The firewall blocks Cygwin though, which is annoying
20:44
I just got upgraded to Win7 from XP myself, but at least we keep up-to-date browsers.
@Iszi our latest machines have Windows 7. Running IE6.
@Gilles Seriously? I didn't think IE6 would run on Win7. Doesn't it come pre-loaded with IE8?
@Iszi mmm, maybe, I didn't pay much attention
The only thing I ever use IE for is our Intranet applications
Yeah, with no restrictions on installing software, who's really gonna use IE anyway?
I use Chrome, Firefox and w3m for everything else
20:46
@Gilles Same here. Only when necessary, and even then via IE Tab in Firefox.
anyway, time to go home
21:48
@ThomasPornin YAY - hi Thomas!
The bear returns!
22:05
@Gilles Nooooooooo
@RoryAlsop it's ok, we can install other browsers
the firewall is more annoying
it blocks Cygwin downloads
it blocks all of imgur.com, so I don't see any pictures on SE
@Gilles I have the same problem at work
it blocks a lot of security-related sites (“hacking”), too, which is really silly considering that my job and that of many of my colleagues involves keeping up-to-date with security issues
22:10
@Gilles My workaround for a range of hacking sites that publish a blog is to let google reader grab the RSS headlines for me to read, then if I see one that looks useful immediately I can go to somewhere to connect to it.
@RoryAlsop that assumes you're looking at recent stuff
@Gilles yeah - true
bizarrely, this means I use my smartphone at work way more than I expected
@RoryAlsop we have very poor mobile phone reception in my building
I get asked to write a report on past attacks on $widgets and find that half the resources are blocked
Ok, it's not as if I didn't know how to work around their firewall, but...
yeah - you want to work within the company constraints where possible, I know :-)
22:44
Well, I think I did probably one of the most geek-ish things I've ever done last night.
I was trying to get a more solid answer on this question...

Q: What is the white flag outside of Starfleet Academy?

IsziI've noticed this in a few episodes now, and have not been able to figure it out. The screenshot below, with a circle added to highlight the flag, is from Star Trek: The Next Generation - Season 5, Episode 26: Time's Arrow, Part I. What is this flag? It appears to be just a plain, white flag...

I'd already seen a few episodes with the flag, but none of them have a really good image to clearly show what the flag is. So, what does my geek brain think?
"I'll just hop on Star Trek Online, beam down to the Academy on Earth, and see the 'real thing'!"
Sadly, it seems the Starfleet Academy Headquarters facility in Star Trek Online is not the same as the TNG-era Headquarters. The flag is not there.
