Here are a number of tips to improve and maintain your mobile device security.
Don’t root your Android device or jailbreak your iOS device
There is no real reason for the average person to have to do this, doing it gives malware an easier route on to your phone as they have administrative access to the operating system.
Have a secure lock screen
Make it as hard as possible for anyone to do something with your phone.
Don’t just think about viruses or malware
Yes, you need anti-virus on your phone. But think outside of the anti-virus protection box. The majority of spyware is installed on phones by people who have access to the device – husband, wife, spouse, family member, work colleague. Be wary of letting people use your phone. Put a good passcode on your phone. Install anti-spyware as well as anti-virus.
Don’t install apps from unofficial app stores
Apps on unofficial stores can have malicious functions behind the scenes. You may have installed a simple game but behind it, it could be stealing your information. Apps on official app stores are screened before they are released to stop this from happening (very occasionally one slips through but is caught soon after).
Don’t click links that are emailed to you
If you get sent a link via email or sms be very wary of what you are clicking, it is better to type the website address into your browser and if there’s a problem with your account there will more than likely be a message waiting for you there.
Pay attention to app permission requests
For example, your flashlight app shouldn’t be asking permission to access your photos, or use WiFi.
Keep your OS and apps updated
Updates aren’t always to improve the OS/app or add new features, sometimes they fix a security hole. Always keep an up-to-date operating system and apps.
