Flashback Attack Part 4

Flashback Attack Part 4
by Gary Woods

Last week we looked at some ways Apple has to protect yourself from further attacks on your beloved Mac. This week we'll finish up the series with some things that I've actually implemented on my own computers.

One solution you might look at is called OpenDNS. DNS is short for Domain Name System and normally when you have a cable company or telephone company that provides you Internet Service you just use their DNS servers. But, if you use OpenDNS which is a free service if you use it at home their DNS servers won't allow you to go to infected sites. A lot of schools and businesses use OpenDNS to keep their students and employees from going to places that could be a problem.

The last thing I'll leave you with is that the Flashback Worm marks another time to have you think about setting up a strong backup system. Ever since OS X 10.5, Leopard we've had Time Machine which couldn't be easier to set up. You just plug in an external drive and turn it on. It works quietly in the background and sucks up all your computer's innards.

I take backup one step farther and use a 2 TB drive which I've partitioned into 4 parts. On the first partition I run Time Machine. On the other 3 partitions I make weekly backups of my entire hard drive using Carbon Copy Cloner. This free software makes bootable copies of your hard drive so with this system I have 3 weeks of backups at any one time.

Then finally, because I'm really paranoid, I use Carbonite which backs up all my important data over the internet. I had 5 friends lose their homes in fires we've had here in Santa Barbara so I'm not taking any chances. Carbonite costs about $5 per month and you can try it free for a couple of weeks to see if you like it. I think $5 per month is a pretty cheap price for complete peace of mind as you to your data.

Anyway, there you have it, some of my thoughts on the Mac, Malware and keeping your data safe.

If you have any suggestions or questions for me please drop me a note at or see my column on the Internet at or call me at (805) 729-0910
