To protect your data, consider the following points:
1. Always update your phone's operating system.
- Whenever you encounter an Android or iOS update message, update your phone's operating system. Many hackers use the vulnerabilities of old operating systems to steal your information.
2. Install a security app on your Android device.
- Many of these apps are free, and you can choose and download the best of them from the Android app stores based on users' feedbacks. If you want to have a higher level of protection for your information, you can buy a paid version of these apps.
Hacking iOS handsets is very difficult, but sometimes it's older versions contain security holes. So, it's best to update your phone as soon as the new version of the operating system is released.
3. Activate the passcode/lock of your phone.
- Turn off your phone's auto-unlock feature.
- To enable the passcode, select a passcode note that hackers can't guess it, but you can remember. First name and last name, date of birth, mobile or fixed number, ID number, etc. are among the passwords that can be easily detected by hackers, so don't use them.
- Enable fingerprint scanner or (if supported) face detection, password, or pattern to unlock on your phone.
- Don't share your phone's passcode with anyone.
- Change your passcode at different times.
4. Before downloading and installing apps, make sure that you've checked their credentials.
- Download apps from valid and reliable stores like App Store and Google Play.
5. Activate/Install the Remote Control Software.
- In case you lose your phone or it's been stolen, you can remotely lock it or erase information stored on it. This application is pre-installed on new mobile phones. This application is known as "Find My iPhone" on iOS phones and "Find My Device" on Android phones.
6. Avoid connecting to insecure Wi-Fi networks.
- The insecure Wi-Fi networks don't have a padlock sign in the list of accessible networks. Connect to a network just if you are sure that it's secure.
- If you don't use Wi-Fi, Bluetooth or GPS on your phone, disable them. Otherwise, hackers may be able to identify your phone and access its information.
7. If you have received a file from an anonymous sender through email or social networks, do not open or run it.
- As long as you keep your email software up to date, opening the email itself does not pose a risk to your information. Therefore, opening emails from unknown people will not cause you problems. But attachments of unknown email can be dangerous, and we suggest avoiding opening them.
8. Do not store your personal information on the phone or send it to someone by phone.
- Suppose your phone is hacked in the worst case; in this case, it's better to not have personal information on your phone.
9-Back up your information.
- Copy your phone's information to the memory card so that you can keep access your data if something happens to the original data.
- If you have a significant amount of data on your phone, you can use "automated backup system" feature and automatically back up your data.
