Conficker – April Fool’s Day Joke?

microsoft_vista-logoApril Fool’s Day joke or a serious threat to your computer? At the moment no one really knows whether the Conficker worm is a serious threat to the world’s computer networks or a sick joke.

The Conficker worm has been around for a little while and its designers (the bad guys) have developed several versions. The good guys (is there such a thing?) have tried to reverse engineer the code and discovered some of the features that could make it a serious threat.

Thanks in part to a quarter-million-dollar bounty on the head of the writer of the worm, offered by Microsoft, security researchers are aggressively digging into the worm’s code as they attempt to engineer a cure or find the writer before the deadline. What’s known so far is that on April 1, all infected computers will come under the control of a master machine located somewhere across the web, at which point anything’s possible. Will the zombie machines become denial of service attack pawns, steal personal information, wipe hard drives, or simply manifest more traditional malware pop-ups and extortion-like come-ons designed to sell you phony security software? No one knows.  (Yahoo!Tech)

Some sources are saying that home computers are at a lesser risk than network machines because home users have firewalls and sit behind hardware routers. In theory this is true but in practice home users often disable their firewalls in order to use P2P networks and torrent services. Home users often have small networks which are shared with laptops and other mobile devices. And, the Conficker variants are often shared via the humble USB key – which we all happily insert into any computer going.

Good news though! Computer worms, trojans and viruses are nothing new – and neither is the method of protection. Here is my list of ways to protect your Windows computers from nasties.

1. Microsoft Windows Update is your friend – head over to Windows update and install everything that it says that you need. This particular security issue was identified last year so an up to date machine is at a lower risk

2. Antivirus products help scan incoming data, assess for virus threats and alert you to their dangers- make sure that yours is up to date and running (Conficker can disable AV products)

3. Antispyware products identify trojans and worms and help protect against the threats that they represent – again update and scan

4. Your firewall is there to serve a purpose – don’t disable it – and don’t believe your kids when they say that everyone uses Limewire, etc to get files …

Still worried?

Microsoft offer a free online scanning service (you must use Internet Explorer to access it). Trend Micro offer the same service as do Panda Security.

For the geeks – who are comfortable editting the registry – disable USB autorun

Who owns your network?

lockWho owns your network?

I have to be really careful here. During my work week I exchange hats on a regular basis. Some of the time I am teacher who wants access now … and then I am technician with lofty views about security … and then I am subverter – I want to get to XXX.co.nz because … I want to …

So who does own your school network? I thought about this question last week when a cluster school couldn’t access a Wikispace or a Zoho Creator database. Their inability to access these sites was only half of the problem though. They had to contact an external technican to have the sites removed from the filtering list.

The network is more than just the internet connection though. It’s also the school’s intranet and it’s also the individual computers and other gear. So who “owns” all of this? And what about the school’s website? Who does it all belong to?

I found this page of Ten Commandments from the Rotorua Education Centre and thought about the networks that I own / manage / work in / attempt to work in. It’s a fairly decent look at what expections a school IT person might have. It also looks at the expectations that a teacher might have about their school laptop. The problem is that the page misses out the other side of the issue. If you are going to use the network you need to be aware of the importance of looking after it. That means being sensitive about passwords and shared network spaces. It means being thoughtful about where you put your 13Gb video file (it’s true – I saw one on a server last week) and it means understanding about quotas (I saw a whole school network brought to a standstill last year when someone tried to synchronise 4Gb of photos and movies over a wireless connection because her son said she should!).

So what’s the answer? I think we need to stop thinking about school laptops and computers in terms of home machines. While they are similar beasts their function puts them in a different cage altogether. I think we need to look at using technicians with an educational background (easier said than done) and we need to think about giving more information to the very people who the network matters most to – the end user.

With this in mind, here’s a brilliant site to download a movie that could just help older kids and teachers understand a little bit more about the connected part of the network. Warriors of the Net is a few years old now (1999) but it does explain a bit about networks and how information is transported around the building and around the world.

Skills checklist

packing(This post originally appeared on Tangled up in Purple)

What does a computer user really need to know? I’m talking about the checklist of skills here that mean that a person can operate the piece of silicon in front of them.

This question is regularly thrown at me by schools that are doing their planning and want to know what skills they should be teaching at year zero, year one, so that they can produce competent users of ICTs at whatever age their students leave. I’m really wary of skills checklists. I believe that everyone needs the same core skills – at any age. If a child starts as a new entrant, they have the same requirements as a child who enters the school at year five. Or for that matter a teacher who moves to the school after many years of working on an alternative platform. While I’m focussing on Macs and PCs here, the same core skills could apply to moving to a Linux platform or using a tablet PC. Or using a PDA or a phone.

  • How to turn it on and off. Don’t laugh – if you come from a PC and want to turn on some Macs it can be a bit tricky, unless you know where the button lives.
  • How to login to a computer and something about what this means. For example if you have logged in as a student (or other restricted user) then you can’t do the same kinds of things as a teacher (in most cases). And that logging in at home might not give you seemless access to some resources. Getting onto the internet might be a bit different at home, for example.
  • Mouse skills are next. And, if the user is on a laptop, touchpad skills. I believe that both Apple Mac and PC users need to understand the power of the right click. Yes, there is a right click on an Apple computer. Just have a fiddle with clicking the right mouse button on a regular USB mouse, or hitting the CTRL key as the same time as a mouse click. There is a huge range of options just waiting to be found.
  • How to start and finish using a programme. Again, don’t laugh because many people – on Macs and PCs – close their window and leave the programme running.
  • How to save and retrieve a file. This includes saving a file in the right place. Many people use MS Word or Excel as a file manager, thinking that you move, delete or copy files from inside the “Save As” dialogue. This is dangerous behaviour!
  • Next, I think people need some keyboard skills. Not typing skills although I do think that some keyboarding skills are useful at some point in a learner’s career. Users need to understand how to make a capital letter (and the difference between the Caps Lock and the Shift key), how to make a space and common punctuation marks. They need to understand common conventions like one space between the words in a sentence and one after the full stop (period). They also need to understand that the programme will be able to sort out the line breaks and that the Enter (Return) key should not be hit when they think that the line is long enough. This works in Word Processors, blog clients, IM software, cellphones …
  • I think that we need to keep using the language of computing. That means that if I am talking about getting my language onto the screen (typing) I use words like Font, Format, Insert and Bullet Point. I talk about Tables when I’m in a word processor and I understand that in a spreadsheeting programme I don’t do a graph but I Chart my results. In all of the programmes that I use I know that Toolbars will help me to complete my tasks and that if I get stuck I am a competant user of the Help files because I can speak the same language as my computer.
  • And, we need a few “physical” internet skills. I understand how to use the address bar and that Google’s search box is not the same as an address bar. I need to learn that it can take a few moments for a page to load and that mad clicking on the same link will actually slow loading pages down.

These are the core skills that I believe are the absolute basics that any competent computer user needs to have. I think they should be taught to all children as they start school and that if someone (student or teacher) moves to a new school, this is where to start.

Of course there are myriads of other things that the competent user needs to know. Many of these things fall naturally into curriculum areas. For example, information skills are critical and they need to be explicitly taught. However they can’t be explicitly taught if a person doesn’t know the difference between the address bar or a search box. So this is my basic checklist that allows all of the other learning to take place. Just don’t put it into a checklist please!
