I have heard about computer vulnerabilities, virus, malware, etc.
Why are these threats possible?
Why doesn't the computer just do the things it is supposed to?
Why do some people write malware, instead of programs with a constructive purpose beyond doing damage and violating the law?

security holes aren't always due to programming bugs, sometimes it's because someone did something that the designers hadn't thought of, and possibly wouldn't have classified as undesirable because they hadn't thought the consequences through
Personally, I don't find that Harvard architectures are that much relevant. But I also think that the NX bit is not very relevant either -- it just trains attackers to be a bit smarter.
@TerryChia If you're prepared to configure everything yourself they're really reasonably priced. If you want fancy stuff, it's a bit more expensive :)
I took an image of my VPS, which is about 5GB in space, and I've had it in their memstore thing for 6 months. So for I have been billed exactly £1 for this privilege.
@TerryChia Ah - they do CentOS as a distribution. It's good practise, especially setting up MTAs etc. I run all my own email with SPF and everything :)
He started to get very upset when I began a discussion about how the virus he was describing couldn't have come from any of my Solaris boxes, and tried to insist that he could see I was on XP because of my (Computer ID).....
@AviD Yeah, the reviews on the web sounds good. I like that they have datecenters in the Asia Pacific region as well, although I'm not sure if that matters much.
@TerryChia I've got a linode for some scanning stuff. Seems to work fine, the dashboard is reasonably comprehensive and I've not had any problems with it..
if you want to do it all yourself, pick up an extra few skills along the way, and dont care about HA - consider building your own powerbox, and loading it up with VMs.
I'm looking at that strongly now, and it is looking good to me.
@AviD Getting a VPS from linode or similar probably makes more sense for me right now. :) Plus I still got to add a new SSD and graphics card to my desktop.
@AviD openvz is a kernel virtualization technology, so you can install any OS, as long as it shares the same kernel
the good about openvz is that you don't need swap
in fact you can use all the unused memory as swap that the host as available
there is just one small catch, there are a lot of sellers that do not have a lot of free memory on their machines, meaning if you run out of memory, you can't swap --> bye bye vps
@AviD I've seen several implementations, for instance a debian machine which has KVM and OpenVZ installed, for Windows machines KVM is used and for all linux machines they used OpenVZ. The nice thing is they can sit next to eachother
@TerryChia Let's say you get 5 micro servers, after 1 year you have to pay
On 2013.02.05 I installed a SL 6.3/64bit minimal, then after install I tried to install a libreoffice-base package. This has been showed to me:
I tried "yum clean metadata" and "yum clean all" but it didn't worked. The same message appeared to me for 2 days.
Today, 2013.02.07 I didn't do an...
I'm torn. For 80% of the q, my finger was ready to migrate to SU. But then the last line does ask a security (-ish) question... though the answer is probably "No.".
but he does have an actual (-ish) security question there: Does it relates to security? Did someone had a proxy between me and ftp.scientificlinux.org?
if it werent for that - it would have been closed already.
@LucasKauffman With the high standards @ScottPack set for this chat, it's pretty hard for anything anyone else says to be considered non-appropriate. :)
We might have sent in apache helicopters to kill the fresh head of Hamas, we might have sent in a C130 to an African country to kill terrorist and blow up some jets.
My current university launched a new program to help students with previous degrees graduate faster by presenting a certificated result transcript from the previous university normalized to ECTS credits.
Well, I've already studied 34 IT-related courses, most of them are programming and software engineering. It's pretty pointless for me to study them again
However, my previous university don't have a way to normalize to ECTS.
So I decided to find my way to the university's mail server and send an email from the student office to the current university.
This question on Security.SE made me think in a rather devious way. At first, I found it to be rather poorly worded, imprecise, and potentially not worth salvaging. After a couple of days I started to realize exactly how many times I’ve really been asked this question by well intentioned, and often, knowledgeable people. The real question should be, “Is there a recommended set of firewall rules that can be used as a standard config?” Or more plainly, I have a bunch of systems, so what rules should they all have no matter what services they provide. Now that is a question that …
Just skimming over your idea, without looking at syntax, it looks pretty reasonable.
@AviD Actually they have between 100 and 200 nuclear warheads. The locations of the underground uranium enrichment facilities are documented, as well as the timing; Israel has been a nuclear power for quite some time. Israel never acknowledged their existence officially because of the Treaty on Nuclear Proliferation.
It always made me wonder how their networks are planned
I don't think it's easy given the nescessary bandwidth
@ScottPack or is he a sysadmin in the sence of "Hi there busty lady, has your internet broken down?", girl: "Yes it has", sysadmin: "let's see if I can put my TP cable in that hole"
@ColinCassidy Happens on a daily basis, I'm sure - along with SSN, DOB, mother's maiden name, etc. It's a side-effect of certain businesses only being open during "business hours" and people who need to do business with those being too busy to leave their desks during that time. Is it a good thing? No. Unfortunately, for many, it just feels like too much work to avoid it.
@ColinCassidy The impact rating of that vulnerability would definitely be high. The acceptance of that risk then comes down to the perceived likelihood of exploitation.
Of course, this would be a risk taken on by the card-holder - not the business on the other end of the phone. The latter has no control and little to no influence of where the former chooses to be when they're conducting business over the phone.
I mean, sure they could insist that all credit transactions are handled via automated system either in person or online. But that will end up in having a bunch of disgruntled users - and businesses don't want that.
Also consider that, regardless of your venue, you're still speaking the information to a person who could be making their own copy of it.
I also suspect that a number of people are not necessarily aware that there is a risk in the first place. most people would assume that their work collegues are fair people.
once again the disgruntled employee is the largest risk
For that matter, ammunition is useless in an Apache to go to work. Ammunition is used to clear traffic jams, so it makes sense to have it on a terrestrial vehicle.
not sure, but I think that we may have just gotten a spam post at security.stackexchange.com/questions/23828/… It's got a link without any info that looks like a link placement since the answer also seems somewhat odd, though passably related to the question (and wrong)
I've got 2 Windows 7 Systems on one hard disk.
Is it possible and if so how can I encrypt both with TrueCrypt, so I can enter the password used for the first System to boot this one, or the second one to boot the second system?

so thats the cool thing about geostat, provided the centre of mass is at the right radius, the object will stay in place, which is how a space elevator would work - it wouldnt need anchoring in theory, it would just...hover...
@AJHenderson yep that one :P but if it was built correctly, the 'wire' would not be under any tension at ground level, so cutting it would have no effect.
@AJHenderson sure, but the counter balance adjustment would be a continuous thing, and could be used to ensure minimum tension in the wire - ie 0 at ground level - at all times
