That Computer Guy

Did you catch Four Corners on ABC this week? It featured a report on the growth of cybercrime in Australia, indicating it’s a problem likely to get bigger with the advent of a national broadband network. I had been looking forward to the piece – sadly though it turned out to be little more than an exercise in fear mongering, complete with over the top soundbites:

“I expect at some stage in the future there will be a real debate on the benefit of the internet. Should we turn it off?”

Don’t get me wrong, it’s good that the subject is exposed to the masses (I’ve had many enquiries regarding computer security since the show aired), and I’m not going to say that cybercrime isn’t a growing issue; but you can certainly inform people in ways that don’t involve scaring the living bejesus out of them!

Obviously this sort of journalism sells, but getting people running around like a headless chook ain’t going to solve the problem. That’s down to education. So, in the spirit of getting things done, let’s get educated shall we? Here’s 5 things you can do to help protect yourself against cybercrime.

(By the way, these tips aren’t new and they certainly aren’t definitive, but obviously they seem to be one of those things that people still need to be told)

1. Think before you click.

No genuine financial institution will send you an email saying they need to verify your details. The best course of action for anything suspect is to phone the institution direct (and either shift+delete to permanently remove the mail from your computer, or follow the procedure the institution advises to send the mail to them if they want to investigate further.)

2. Keep your computer updated.

Installing the latest manufacturuer patches and anti-virus signatures kind of goes without saying, but I’ll bet many of you don’t do it!

3. Install an Anti Spyware product.

Most of the brand name security manufacturers such as Symantec / Norton & McAfee will have an “Internet Security” product that bundles this with Anti Virus software. If you don’t have one of these products already or have just standard AV software, I recommend “Spybot S&D” which you can download for free, or Windows Defender, also free.

4. Ensure your user account doesn’t have administrator rights.

Hackers like to install software that does their bidding on your PC, but they usually need administrator rights to do it. By only giving the account you log on to your computer with the minimum of privileges, it makes it all that much harder. Microsoft Vista introduced a feature called UAC (User Account Control) to try and fix this problem; sadly it was so poorly implemented that many people turned it off altogether. Happily though, the version in Windows 7 works.

5. Protect your wireless network.

There are many things you can do to aid your protection if you’re running a wireless network in your home or office. First, check the type of security you’re using. If you have a setting for WPA (Wi-Fi Protected Access) or WPA2 and higher, make sure you’re using it. If your router is slightly older and only has a setting for WEP (Wireless Encryption Protocol), please go and drop some cash on a new one – WEP was cracked a few years ago, so you could be leaving yourself wide open.

Also, make sure your firewall is turned on; change and then turn off the broadcast of your network’s name (known as the SSID) and use a pass phrase (including upper case letters and numbers), rather than a password for the wireless authentication.

Hopefully you found these tips on protecting yourself against cybercrime useful. If you have any more, or if you want to add your own opinion on this topic, please leave a comment below.

I am, and as some of my clients will agree, a bit of a Google tragic – I do like their stuff.

In my defence though, I have to say that’s it’s purely for the simplicity and usefulness of their products. You have a problem, they solve it. You have a problem you didn’t know you had? Chances are they’ve got that covered too. And into this latter group falls a new feature in Google’s email client – Gmail.

Gmail has been a staple for me for a while now, and I’m hooked on that you can centralise all of your email domains to it. Being a mobile worker and yet still able to access any of my email addresses in one place is a golden goal!

What I’d overlooked until recently though was that users of some email software, and in particular Microsoft Outlook, would see my emails as coming from “myaddress@gmail.com on behalf of myemail@mydomain.net”. Now, given my rant on why you should get your business a domain name, this was not ideal, to say the least!

Today, the “Big G” ticks off that box by introducing the ability to set which outgoing mail server you want to use for your mail – your domain server or Google’s server. Here’s how the process looks without this feature:

And here’s how it works after enabling:

For mobile workers or those with multiple email addresses like myself, this means I can log on to my Gmail wherever I happen to be, and still know that emails to my clients appear as if they are from my domain address, regardless of the software they are using.

Here’s how to set up “Send mail from another address without on behalf of” in Gmail:

Firstly, you’ll need your email domain details. You can usually find these on your ISP’s website, in a welcome letter, or on your website’s control panel (cpanel or similar). Once you have these, log in to your Gmail account and look for “Settings” towards the top right hand corner.

Select the “Accounts” tab:

And then click on “Edit Info” on the right:

If the settings you have in the next screen are as you want, click “Next Step”

Hit the radio button for “Send through your ‘domainname’ SMTP servers…” and enter the details you gathered previously. Depending on your settings, you may need to tick the checkbox to always use a secure connection. Click “Save Changes” and you’re all done!
