Maximising Smartphone Security: Top Practices for Users

In an era where smartphones are practically an extension of ourselves, the importance of mobile security cannot be overstated. These devices hold a treasure trove of personal information, from bank details to intimate conversations. According to a report by NortonLifeLock, mobile malware attacks increased by 54% in 2020 alone. The purpose of this blog is to educate you, the end-user, on the best practices to maximise your smartphone security.

Common Smartphone Security Threats


Malware is software designed to infiltrate or damage a computer system without the owner’s informed consent. On smartphones, malware can steal personal information, record conversations, and even control your device remotely.


Spyware is a subset of malware that specifically focuses on monitoring and sending your personal data to a third party. It can record keystrokes, capture screen shots, and access your contact list.


Phishing attacks often come in the form of seemingly legitimate messages or emails that trick you into revealing your personal information. These can be particularly dangerous when they mimic messages from trusted sources like your bank.


Ransomware locks you out of your device or encrypts your files, demanding a ransom to restore access.

Jailbreaking and Rooting

Jailbreaking (iOS) and rooting (Android) are processes that remove certain restrictions on your device, potentially exposing it to various security threats.

Best Practices for Maximising Smartphone Security


A. Keeping Your Device Up-to-Date

Importance of Software Updates

Software updates are not just about adding new features; they often contain critical security patches. Outdated software is a breeding ground for hackers to exploit known vulnerabilities.

How to Update Software

Android: Go to Settings > System > Advanced > System Update > Check for Update.

iOS: Navigate to Settings > General > Software Update.


B. Installing Trusted Security Apps

Benefits and Tips

Security apps can scan for malware, block malicious websites, and even provide a firewall. When choosing a security app, look for reputable companies, read user reviews, and check for a history of regular updates.

Recommended Apps

Android: Bitdefender, Avast

iOS: Norton, McAfee

C. Using Strong, Unique Passwords and Two-Factor Authentication

Importance of Passwords

Strong, unique passwords are your first line of defence. Using the same password across multiple platforms makes you an easy target.

Two-Factor Authentication

Two-factor authentication (2FA) adds an extra layer of security by requiring a second form of identification beyond just a password.

How to Set Up 2FA

Google: Go to your Google Account > Security > 2-Step Verification.

Apple: Settings > [your name] > Password & Security > Turn on Two-Factor Authentication.

Strong, Unique Passwords and Two-Factor Authentication

D. Being Cautious of App Permissions and Downloads

App Permissions

Be wary of apps that request permissions that aren’t necessary for their function. For example, a weather app shouldn’t need access to your contacts.

Trusted Sources

Only download apps from trusted sources like Google Play Store or Apple App Store.


E. Don’t Jailbreak or Root Your Phone

Jailbreaking (for iOS devices) or rooting (for Android) involves bypassing the built-in security protocols of your smartphone’s operating system to gain elevated access to its features. While this may offer more control and customisation options, it significantly compromises the security of your device, making it more vulnerable to malware, data breaches, and other cyber threats.


F. Safeguarding Against Phishing Attacks

What Are Phishing Attacks?

Phishing attacks trick you into divulging personal information. They often mimic trusted sources.

Tips for Recognising Phishing

Be cautious of unsolicited communications asking for personal information. Always double-check the URL and the sender’s email.

G. Avoiding Unsecured Wi-Fi Networks


Unsecured Wi-Fi networks are a haven for hackers to intercept your data.

Tips for Safe Use

If you must use public Wi-Fi, avoid accessing sensitive information and consider using a VPN.


H. Securing Your Online Presence Beyond Your Smartphone

Safe Browsing Habits

Always look for “https://” in the URL. Use incognito mode for sensitive searches.

VPNs and Data Backups

A VPN encrypts your online activity. Regular data backups protect you from data loss due to malware or hardware failure.


I. Smartphone Security for Children and Teens

Unique Considerations

Younger users are more susceptible to clicking on malicious links and downloading rogue apps.

Tips for Parents

Educate your children about the risks. Use parental control features to monitor app downloads and screen time.

By adhering to these best practices, you’re not just protecting your smartphone; you’re safeguarding your digital life.

Consequences of Not Having Proper Smartphone Security


In the digital age, the ramifications of lax smartphone security can be devastating. Here are some of the most pressing consequences:

Data Theft

If your smartphone is compromised, hackers can gain access to your personal data, including photos, messages, and even sensitive financial information.

Privacy Invasion

Spyware and other malicious software can record your conversations, track your location, and even access your camera and microphone without your knowledge.

Financial Loss

With access to your banking apps and payment methods, cybercriminals can make unauthorized transactions, leading to significant financial loss.

Man-in-the-Middle (MitM) Attacks

These attacks occur when a hacker intercepts communication between two parties. This can happen on unsecured Wi-Fi networks and can lead to data theft or account hijacking.

Emotional Distress

The invasion of your personal space and the theft of your personal data can lead to significant emotional distress, affecting your well-being.

Legal Consequences

If your phone is used to commit a crime, you could potentially face legal repercussions, even if you are not the one who committed the act.

Loss of Intellectual Property

For those who use their smartphones for work, a security breach could mean the loss of valuable intellectual property, affecting not just you but also your organisation.

The Role of Telecommunication Companies in Smartphone Security

Telecommunication companies play a pivotal role in ensuring the security of mobile devices. They are responsible for the networks we rely on and can offer additional layers of security to protect against various threats.
