How to keep your smartphone secure

The latest ransomware app uncovered in the wild has brought to the fore the need for greater smartphone security awareness, particularly the dangers of downloading apps from unofficial, unverified sources. The most effective viruses combine social engineering and technical expertise, in this regard the Adult Player Android app is typical.

However, it would be naive to assume that by simply using applications downloaded from official sources that users are left free from harm – the risks that users may potentially run into are as varied as mankind itself. Below are some simple tips to avoid the many pitfalls of smartphone usage.

1. Secure your device by setting a screen lock with a PIN, password, or pattern:

Android instructions
Go to Settings → Security → Lock screen → Screen lock

iOS instructions
Go to 'Settings' → Passcode → Choose between 'simple' (4 digit pin) and 'regular' passcode (alphanumeric) → Turn passcode on → Create passcode from prompt → Choose when the passcode activates → Choose whether the phone wipes data after ten failed attempts → Choose whether or not to allow certain apps to be accessed without unlocking the device

2. Turn on 2 factor verification (also known as 2 factor authentication) where possible.

3. Keep operating system up to date. Many updates are designed to close security loopholes.

4. Keep bluetooth connection turned off when not being used.

5. Only download apps from reliable sources. Avoid downloading paid apps from websites that claim to offer them for free. (Tie in android ransomware dangers)

6. Do not connect to unsecured, open WiFi networks. Impostor Wi-Fi networks can be used to stage a ‘middleman’ attack, any data can be intercepted by a third party – including passwords and personal details, such as credit card numbers.

7. Use a VPN. Find a good paid service. It is unlikely that you will find a free service for that does not compromise user privacy or security. The best services do not keep user logs.

8. Avoid storing sensitive information on external storage. A micro SD card can be removed potentially exposed to third parties.

9. Check app permissions when installing new apps. Ensure that unnecessary permissions are not being granted – a wallpaper app or a game does not need access to email, SMS or unlimited internet, for example.

10. Do not allow apps to broadcast your location unwittingly. Keep your location private unless using region specific or navigation software. Not only will this protect you from phishing but may also protect you from more immediate threats such as kidnapping and robbery.
