1. Establishing Strong Screen Locks

Strong screen locks are essential

The first line of defence in smartphone security is establishing a strong screen lock, which acts as a barrier against unauthorised access to your device. There are various types of screen locks available, including PIN codes, passwords, fingerprints, and face ID. But what constitutes a strong screen lock? It should be a combination of at least four characters long, consisting of letters, numbers, and symbols, making it the most secure option.

Creating secure passwords for your screen lock can be a daunting task. However, a helpful trick is to use the initial letters of a memorable phrase, song lyrics, or quote, and then substitute some characters with numbers or symbols. For example, the phrase “To be or not to be, that is the question” could become “Tb0nt0b,t1tQ!”. Remember to update your screen lock password periodically to maintain optimal security.

Besides setting a strong screen lock, consider adding a SIM card lock, which requires a PIN code to access the phone locked SIM card and make calls or send text messages. This additional layer of user authentication can further enhance your mobile device security, especially if your phone gets lost or stolen.

2. Safeguarding Sensitive Data

Safeguarding smartphone data

Protecting sensitive data on your mobile device is crucial, as unauthorised access can lead to identity theft or financial loss. One of the most effective ways to secure your data is encryption. Encryption is a process used to secure the user data stored on an Android device. It involves encoding the information with an encrypted key. To encrypt an Android device, ensure the device is 80% charged and unrooted before starting the process. Be aware that if you forget the password to unlock an encrypted phone, the only way to regain access is through a complete factory reset.

Another way to protect sensitive data is by using remote lock screen, and data wipe features. Remote lock and data wipe is a security policy that enables businesses or individuals to remotely erase or lock a mobile device in the event of loss or theft. Make sure to be well informed about such policies, especially if you’re using a Bring Your Own Device (BYOD) policy at work.

Establishing strong passwords for your applications is also essential to protect your personal and professional data. Use a combination of letters, numbers, and symbols to create secure passwords and update them regularly. Consider using a password manager to store and generate unique passwords for each of your online accounts.

Lastly, be cautious when working remotely on mobile devices, as this may increase the risk of security breaches. Always ensure that you are connected to a secure network and avoid sharing sensitive data over unsecured connections.

4. Regular Data Backup

Backing up your smartphone data is essential to protect and retrieve your information, especially if your device becomes infected or compromised. Backing up your data externally to the smartphone protects against potential phone loss, damage, malware, or theft.

Regular external data backups guarantees convenient access to your files from any location, ensuring that your data remains safe even if your device is compromised.

External data backups are often referred to as cloud backups. The “cloud” in smartphone (and computing) terms can be described as a global network of servers that are connected and operate over the internet. These servers are designed to store and manage data, run applications, deliver content or services, and much more.

In simple terms, when you use the cloud to store your data, it means you’re using computing resources (like storage) that are not located on your own device, but are instead delivered to you over the internet from these remote servers.

For example, if you’ve ever used email services like Gmail, streamed movies on Netflix, or stored photos on Dropbox, you’ve used the cloud. Instead of storing your emails, movies, or photos on your personal computer or phone, they’re stored on the servers of these companies and you access them over the internet. This allows you to access your data from any device that has an internet connection, not just your personal device.

With several cloud-to-cloud backup solutions available, you can easily protect your deleted files or earlier versions from being permanently lost.

To enable automatic backup on Android devices, configure the settings in the Photos app. When establishing automatic backup, it is essential to prevent rapid depletion of the internet traffic allocated by your data plan. Configure the system to back up only when connected to a Wi-Fi network to avoid excessive data usage.

Investing in automatic backups in the cloud has several advantages. All applications and data will be seamlessly synchronised in the cloud, eliminating the need to manually back up all your data and providing an additional layer of protection for your files.
