Smartphone Security

It is much smaller than your desktop PC, but the risks are equally great .........

Hang on Tight
Currently, the number one threat to smartphone users is having the device end up in the wrong hands, through theft or loss. Your first line of defense, therefore, is constant vigilance regarding your smartphone’s whereabouts.
Use a Password and Encryption
Should your phone get lost or stolen, a good first layer of protection is a password, an option many phone users neglect. Choose the strongest password option available—a passphrase, for instance, rather than a four-digit code or swipe pattern. Encryption options vary among mobile OSes, but when possible, you should encrypt your storage card as well as your device memory. Back Up Your Data Just as with a PC, backing up your smartphone is important. Regularly synching the device to a linked computer will do the trick. It’s insurance against the loss of your phone, corruption of your OS, or any other event that jeopardizes your data.
Don’t Store Sensitive Data
The surest way to guard your sensitive data is to keep it off your smartphone altogether. Minimize the number and/or days of emails you store on your phone, or better yet, save email and attachments to a server. Make it a habit to regularly move or delete anything you wouldn’t want to share with strangers.
Practice App Awareness
An abundance of apps is both a blessing and a curse for smartphones—there is no way every app that makes it to market can be thoroughly vetted for 100 percent fail-safe security. By selecting reputable apps, backed by favorable user reviews, from a trusted source, you can diminish the risks. Avoid apps with scant reviews or that have only recently been uploaded. Also be cautious when granting an app permissions; consider the app’s function and what it might reasonably need access to.
Keep Software/Firmware Updated
Make sure you are running the latest versions of your apps, OS, and phone manufacturer software and fi rmware. This will ensure that any security holes are patched and your device is less vulnerable to hacks.
Disable Bluetooth and Wi-Fi When Not in Use
Unsecured wireless networks can be used by hackers to either attack your phone or steal information from it. You can protect yourself by keeping Wi-Fi and Bluetooth off when you don’t need them. When wireless is needed, stick to known Wi-Fi networks using WPA2 and beware of public networks, which are sometimes set up by crooks to snare people’s data.
When using Bluetooth, make sure it’s in non-discoverable mode to avoid hacks like “Bluesnarfi ng” (stealing data), “Bluejacking” (sending unsolicited messages), and “Bluebugging” (listening in on your calls).
Beware of Links and Attachments
You’ve long been warned about the risks of opening strange links and attachments— particularly those arriving in unsolicited emails or text messages. All those same warnings apply to smartphones. And those warnings also apply to calling unfamiliar phone numbers received in messages, and clicking links for app “updates.” You can ensure the authenticity of an update by going to the app’s website.
