5 ways to spring clean your security

5 ways to spring clean your security

It is now officailly spring in the Northern Hemisphere, and with spring and the longer days comes the inescapable urge to shake off the lethargy of Winter and embrace the need to go through your stuff, throw a bunch of it out, and give the rest of it a shiny new lustre.

And in our increasingly digital lives, more and more of our stuff exists as bits and bytes on our phones, tablets, laptops and desktop computers. With the trees now full of blossom and the air prickling with pollen, you may feel an urge to straighten out your digital mess too.

If you do, we’ve got your back, and we humbly suggest that when you’re done tagging your dog in every photo and getting your folder names just so, you turn your attention to your device security and give that a little dust off as well. After all, nothing makes a bigger mess of your digital life than malware rummaging through it.

1. Say “yes” to software updates

Patching (downloading software updates) is like fixing the broken locks on the front doors of your digital life—the updates contain code that fixes weaknesses that thieves could otherwise jimmy open with their digital crowbars.

Start your spring clean by downloading all the software updates you’ve been putting off. Especially the big ones.

And yes, you’ve heard this advice before (we hope). Maybe you’ve heard it a hundred times, and maybe you’re heard it so often that you’re tired of hearing it and looking for some otheradvice. Well, fine, there’s some other advice below, but this is number one in our list for a reason, so please don’t skip it. This is the first and most important thing you can do to give your digtal security a spring boost.

2. Say “no” to duplicate passwords

How many online accounts do you have? Twenty, thirty, one hundred? And how many different passwords do you have for all those accounts? If the answer to these two questions isn’t exactly the same number—meaning that you have as many different passwords as you have different accounts—then you have some cleaning up to do.

Criminal hackers love it when you use the same password for more than one account. Once they’ve done the hard work of cracking one of your passwords they aren’t going to waste it, they’re going to try it on a laundry list of other websites to see what else it can unlock for them. It’s like a twofer at the grocery store for them: Hack one account, get one free!

The way to stop this is to create a unique password for each of your accounts, no exceptions. If you’re up for a deep clean then get yourself a password managerto make the job of creating and storing all those passwords easy. It’s a little more effort upfront, but well worth it.

3. Lose what you don’t use

We’re going to leave you to decide where you want to take this one and how far you want to go with it. We’ll just get you started with this simple line of thinking: From a security perspective, “more” is often worse. More apps means more places a hacker might find a broken lock or an open window they can use to break into your device. The same thing goes for your online accounts—each one is a potential way in to your digital life (particularly the accounts you haven’t used for a while, aren’t paying much attention to, or didn’t bother to lock down very well).

It’s amazing how many rarely-if-ever-used apps we accumulate on our devices, and how many accounts we open and then abandon online.

So why not lose some things? Ditch some apps you don’t need, clear out your unused browser add-ons, and delete some accounts you don’t use. The more you lose, the better.

4. Get on top of your email

Criminals use email to spread malware, fakes, and scams, so it is worth paying some attention to. Getting your unread email count to zero is immensely satisfying, and if you do it the right way it can give your security a spring in its step too.

Start by unsubscribing from all the mailing lists and newsletters you never read. You want the email that arrives in your inbox to be full of things that actually interest you, so it’s easier for you (and your spam filter) to spot anything that is slightly off. It’s just like step #3—lose what you don’t use.

Now go through your email and mark the things that look like scams, spams, malware, or junk as “Junk” or “Spam.” Every time you do that instead of just deleting shady emails you are actually training your email’s spam filter to work more effectively (if you want to know why, read our article on Bayesian Filtering). To work correctly your spam filter needs a few thousand up-to-date examples of both “good” emails and “bad” emails, so you want your inbox to be full of good things you care about, and your spam folder to be full of bad things that are malicious or spammy.

5. Run a malware scan

Spring cleaning is about the satisfaction of a job well done, and the peace of mind that comes with knowing your environment isn’t harbouring any nasties. To get that same sense of inner calm from your computer, put down the bleach and pick up a malware scanner.

A malware scanner is the quintessential deep clean for your device. It will pick over your files and apps, one by one, and run through them with a fine tooth comb, weeding out any malware that’s lurking in there undetected.

Now, we’re going to toot our own horn a little on this one. We try to give good, sensible, impartial advice on this blog, without somehow making everything about us and the things we make. Well it so happens that our scans are famous for their ability to pick up things that others miss, and it wouldn’t make any sense if we didn’t mention it when other people will happily tell youthe same thing. So, if you want to scrub all the dark and difficult corners of your desktop or laptop computer, we honestly think the best advice we can give you is to run our anti-malware scanner. Sorry, not sorry.
