GIZMO SPECIAL What You Really Need To Know About Smartphone Security
Your smartphone is a computer in
your pocket, and it often contains just as much private data. All of your
emails, location history, Web history and app usage are likely accessible
through the device on your pocket. This makes it well worth protecting, but the
threats you should worry about extend beyond.
VIRUSES EXIST
Since a smartphone is like a computer, it is
vulnerable to similar security threats. Malware can be used to monitor data
transferred on a phone, hijack specific data (like credit card numbers) or
simply corrupt apps and generally make your life diffi cult. There are millions
of potential threats in existence, and while most are unlikely to cross your
path, the risk is higher than you might have guessed.
Smartphone viruses also emulate
their PC brethren in the way they spread; anyway they can. They can arrive via
text message, through a Web attack that exploits vulnerabilities in your web
browser, or through an exploit in your phone's networking capabilities.
This is why, as is true with PCs, the advice of “just don't download a virus, dummy,“ doesn't always work.

NO PLATFORM IS IMMUNE,
THOUGH SOME ARE BETTER THAN OTHERS
The operating system your smartphone
runs has a significant impact on the threats you must be concerned with.
Android, which is the most popular and most open, is predictably the least secure. This isn't entirely Google's fault, as it's effectively become the Windows of the smartphone world. Everyone targets Android because it offers the largest pool of potential victims.

Apple's iOS is more secure because
it is more tightly controlled. The company rigorously oversees the app store,
does not allow the installation of apps from any alternative source, and
closely integrates the operating system with its hardware. While security flaws
have been found in iOS there have been no confirmed reports of an in-the-wild
virus (though there have been a few apps that behaved badly, albeit within the
confines of the permissions given to them).
With that said, jailbreaking your iOS device and using “unauthorised“ apps opens you to a variety of potential threats.

BlackBerry viruses have been report
ed, though they're not particularly common, and Windows Phone has yet to fall
victim to a virus. That may change, however, if the operating system becomes
more popular.
SECURITY APPS AREN'T
ALWAYS WORTH THEIR TITLE
All of this doom and gloom is likely
to send you screaming towards the nearest security app, but be careful. Not all
security apps work equally well, and not all of them actually protect you.
Android users can make an informed
decision about the antivirus they use by view ing the latest reports from AV
Test (bit.ly/1lmASPP) and AV Comparatives (bit. ly/1jKWwZJ). These
organisations compare antivirus solutions by throwing a collection of malware
at each app. Established names like Kaspersky, Bitdefender and Avast! often win
these contests, but some lesser-known companies like ESET and AhnLab have
scored well, too.
BlackBerry and Windows Phone users,
however, have no such scores to go by. Users on these platforms should play it
safe and stick to apps from companies that have a proven track record in
Windows and Android. Most antivi rus apps do what they say, but not all of them
work equally well.
AV Test's last round-up found that two entries, VIRUSfighter Antivirus Pro and Zoner AntiVirus, let through at least a quarter of all threats. These aren't unpopular apps; both of them have four-star rank ings on Google Play and Zoner has been recommended over 20,000 times on Google Plus.

And then, of course, there are the
inevi table fakes. In April of 2014 a new antivirus app called Virus Shield
appeared with a price of $4 and rose to the top of the paid apps list. Just one
problem; it didn't actually do anything.
Though eventual ly removed, over
10,000 users down loaded it before it was taken down.
The moral of the story? Do your
research and don't fall for spanking-new securi ty apps that promise perfect
security.
A LOST PHONE CAN BE
WORSE THAN A VIRUS
Worrying about malware can keep your
attention locked on just one problem. However, there's another issue that's
just a disconcerting, and far more likely; the loss of your phone, either
accidentally or because it was stolen. A phone in a stranger's hands opens you
to all the security issues we've already touched on. Everything stored on your
phone can be accessed, from your saved credit cards to your email inbox, no
virus required, and anti-virus can't do a thing to protect you.
What can protect you is preemptive
action. Place a lock on your phone.
Backup your data. And make sure
you're aware of the tools available for remotely wiping your phone if it goes
missing.
Waiting until after your phone is
already missing may be too late, so don't hesitate to familiarise yourself with
your smartphone's security. The process only takes a few minutes.
WHERE THERE'S DATA,
THERE'S RISK
Keeping your phone secure is now a complex,
multistage process. That's unfortunate, but also inevitable given their
expanding capabilities.
Where there's data, there will be
someone who wants to obtain it, often through illegitimate means.
The good news is that all smartphone
manufacturers have become wise to the problem in short order, so most modern
devices offer backup, remote wipe and lock features by default. You'll also
find that there's a wide variety of effective antivirus solu tions, some of
which are absolutely free.
While certainly worth a bit of worry, smartphones are still easier, and less expensive, to protect than a PC.
