3 Defensive Strategies to Thwart Cyber Attacks

3 Defensive Strategies to
Thwart Cyber Attacks

I am not at all knowledgeable to know anything about cyber attacks, far less what to do about it. However, I am in the unique position of having a second Computer Scientist from Oxford University staying with me at the moment.

Yes, that is the famous Oxford University, here in the UK.

3 Defensive Strategies to Thwart Cyber AttacksAnd cyber attacks now seem to be a problem for all of us. So tips from the best in the world – even if they are only 3 basic tips, are like little gems of information.

Apparently these gruesome people haven’t attacked Apple users, yet. It seems to be windows based attacks. But we should all be vigilant, and not let these criminals get away with it.

How do they get to you?

Well my friend from the Oxford School of Computer Science says it is through “Social Engineering”. It could be a legitimate looking email, for example. Remember, we used to get emails from some Nigerian Prince, who needed help? Well that used to be the referred method. However, today they are more sophisticated and ‘socially engineered’.

By the way, your bank will never write to you about your account – only unless you have initiated such a conversation and they are replying.

This major attack yesterday seems to have started in the Ukraine in Europe but quickly spread to cause havoc around the world. It crippled computers, stopped things working for large firms like Maersk. Tragically, even Cadbury’s the chocolate makers in Australia got hit. I say tragically, because I love chocolate!!!

Even Chernobyl seems to have been hit. So, they say they had to monitor radiation levels manually after its Windows-based sensors were shut down.

Kaspersky Lab the Russian anti-virus firm said its analysis showed that there had been about 2,000 attacks – most in Ukraine, Russia and Poland.

What Happens?

It’s a virus, which freezes the user’s computer. You then get a demand that doesn’t seem to be traceable – a ransom be paid in the digital Bitcoin currency.

And people have paid out. You can choose not to pay and then pay highly, to sort the problem. But the attackers seem to know how much each individual firm would need to pay. So for example if it might cost you $100,000 to solve the problem the Attackers ask for $20,000 – so you pay.

How much is your data worth to you?

Here are the 3 Defensive Strategies to Thwart Cyber Attacks suggested to me by my guest from
the Oxford School of Computer Science:

  1. Back up your data to an external drive – don’t leave it plugged into you computer! Or, back up to the various cloud backups.

  2. Thwart them with regular ‘patching’ i.e. updates folks. Update quickly all the time J

  3. Finally, if you are attacked – don’t pay up! If you have done all of the above then you can completely reformat you computer. But it is a case of wiping everything and starting again. You can’t pick and choose what you are going to wipe and what you aren’t, I’m afraid.

So, it’s really simple when you think about it!

Yet, how many of us will do it, do, do it?

Make it a habit I say. They tell us it takes 30days to form a habit (some say 60, some say 90) just start now!
