Here are some practical steps to help you minimize your mobile device’s exposure to unauthorized access and digital threats.

The rapid development of technology and the portability of mobile devices make people highly dependent on these products. Mobile phones perform some of our daily activities with improved performance, such as surfing the Internet, making appointments, setting reminders, file sharing, instant messaging, video calling, and even mobile banking.

With all these features in mind, cell phones are vulnerable to network threats and vulnerable to physical attacks due to their portability. Some security threats include malware specifically targeted to mobile devices, such as worms and spyware, unauthorized access, phishing, and theft.

But all is not yet lost. Here are some practical steps to help you minimize your mobile device‘s exposure to digital threats.

1) Keep your remote tracking and lock settings enabled

Here we assume that you have activated your mobile phone screen lock with a multi-digit password, facial/fingerprint recognition or complex pattern. This is especially useful if you’ve lost your phone or your device is broken. If you think locking your screen prevents thieves from compromising your phone, you don’t know what tricks hackers can bypass your phone’s original security mechanism. Even fingerprint and facial recognition protection can be bypassed!

Here’s a great way to lock your device. This is the first step in protecting your phone from hackers or anyone else who shouldn’t have access to your device. Luckily, almost all telecom providers offer Find My Device and Remote Key features. All you need to do is install these programs (if they are not pre-installed on your device) and register your device.

For example, you can use Find My Google for Android phones and My iPhone for Apple phones. These programs also allow you to lock your phone remotely. If you are sure that your phone is in the wrong hands, you can also wipe all phone memory so that no one can misuse your data. Deleting data from your phone is a risky step. Back up your necessary data regularly.

2) Avoid public Wi-Fi

Everyone should be aware of the dangers of using an open web network because a free web network in malls, cafes, airports or any other public place is open to all sorts of internet pranks. Try not to use public Wi-Fi for your professional work.

Whenever possible, try to use only your mobile phone and completely turn off your internet connection when you are in a public place. If that’s not possible, consider using a VPN program, a utility that tunnels network communication through an encrypted connection. But choose carefully – not all VPNs are created equal. Also remember to turn off Bluetooth while you’re away if you don’t have a connected watch that needs it.

3) Encrypt your device

Most portable devices come with built-in encryption. Encryption is the process that makes data unreadable. Decryption transforms unreadable data into average data. This is important in case of theft and prevents unauthorized access. To encrypt your device, you just need to find this feature and enter your password.

This process may take some time, depending on the size of your data. The more data, the longer it lasts. More importantly, it would be helpful for you to remember the encryption password as it is required every time you want to use your cell phone.

Also consider backing up your data for security, as some cell phones will automatically delete everything if an incorrectly entered password is encrypted.

4) Install security software tools on your mobile device

Antivirus programs and anti-malware software are not limited to computers. It would be better if you use these software on your mobile phone to protect your data from hackers. While browsing the Internet, malicious websites may allow you to install different types of malware (such as viruses, Trojans, worms, etc.) on your device. Your device may also be infected with malicious add-ons or email programs.

In addition to detecting and removing malware, security software can alert you when you visit a malicious website or download a malicious program. Some malware is downloaded to your phone without your knowledge.

5) Enable Bluetooth connection loss notification on your smartwatch

Connect your phone to a smartwatch and activate the Bluetooth loss notification feature (or one of the terms used in your particular device). This feature is available on Android and Apple watches. If the watch disconnects from Bluetooth, it notifies the user. If you are in a public place and the phone leaves the designated area, the smartwatch will notify you immediately.

The device’s Bluetooth connection is lost on average within 100 meters. Therefore, when you receive a message like this, you know your phone is always nearby and you can find it right away. You can hear the phone ringing even when the device is not turned off. You can also use Find iPhone from iPhone or Find My Device to generate a beep (beep or ringtone) even when the phone is turned off.

Pro tip: Protect yourself against SIM card swapping

To protect your SIM card from unauthorized modification or porting, set a one-time PIN or password with your mobile operator. You know this number and all you need to do is access or change your mobile account (including porting your number/account to other devices).

You can also use programs such as Google Authenticator, Authy, or Google’s no-code authentication method to add another layer of security. Apple’s 2-Step Verification feature can send an OTP to a registered device (rather than a phone number) when someone tries to sign in from a new device. This adds an extra layer of SMS-based MFA security to your device.

In other words, even if an attacker inserts a new SIM card into a new device, he cannot activate it until he presents an OTP that iOS sends only to your (registered) device or to any other phone number connected/connected. You can also set a specific password so that no one can access your programs without entering these passwords.
