Six tips to make your Mac safer
In the wake of Flashback, everybody's asking if Macs are still safe. Here are six easy tips on how to be your own gatekeeper.
The Flashback Trojan went viral last week, infecting an estimated 1 percent of OS X computers worldwide. While the infection rate has subsided since then, that doesn't mean Mac owners should return to complacency.
It doesn't mean that there's cause for panic, either. Here are some common sense, effective tips for safeguarding your Mac against more malware.
It's important to have a security suite on your Mac because they block the kind of automatic drive-by downloads that afflict otherwise safe Web sites, and if one does get through, they can warn you when it attempts to install something. Around 70 percent of the top 100 Web sites have inadvertently distributed malware. In the case of Flashback, it actually had a piece of "greener pastures" code written into it that would abort the installation if it detected a security suite. Running a security program is just common sense. You can schedule a once-weekly scan, and have it protect you in the background the rest of the time.
There are both free and paid options, including Avast (download), Sophos (download), ClamXav (download), Kaspersky (download, trial), and Intego (download, trial).
If you're dead-set against running a full suite, at the very least use a browser tool that will check links to make sure they're safe before you load them. AVG LinkScanner (download) is a good place to start.
It would also mean switching to Google Chrome (download), which is the only browser that comes with Flash built-in. Google updates Chrome regularly, and the browser has earned its reputation alongside Firefox as a safe browser that patches security problems when discovered.
You can disable Java by going to the Applications folder then Utilities, and unchecking the Java version boxes under the General tab.
There are additional tips, such as grabbing a firewall monitor like Little Snitch (download), using the built-in disk encryption tool to protect your data, or following the NSA's tips on 'hardening' your Mac (PDF), but those require way more security firepower than most people require.
People can and do run Macs without paying attention to security, but as we've seen over the past year, attacks centered on Macs are almost certainly going to increase. These tips will help you stay ahead of the bad guys.
