A single lapse in security when using a mobile device can expose your private data, leaving you vulnerable to fraud, identity theft or financial losses. By applying the right measures, you can keep your device and personal information secure from cyber risks.
Implement strong authentication
A weak password or a simple PIN makes it easy for someone to access your phone if it’s lost or stolen, and default security settings often don’t provide enough protection.
Strengthen your device security by using multi-factor authentication (MFA) whenever possible. A combination of biometric verification, such as fingerprint or facial recognition, and a strong passcode creates a formidable barrier against unauthorised access.
If your device supports it, enable biometric authentication alongside a complex alphanumeric password. Even if someone tries to breach your security, this layered approach significantly reduces the chances of unauthorised entry.
Keep software updated
Outdated software is a goldmine for hackers. Cybercriminals exploit known vulnerabilities in old versions of operating systems and apps, making unpatched devices easy targets. When developers release updates, they often include crucial security patches that close these gaps.
Ensure that your mobile operating system and apps are always running the latest versions. Enable automatic updates whenever possible so that you don’t miss critical security fixes. Keeping your software up to date prevents attackers from taking advantage of known weaknesses and reinforces your device’s overall security.
Use encryption and online VPN
Your personal and financial data can be intercepted when transmitted over unsecured networks. Encryption protects this information by scrambling it into unreadable code that only authorised parties can decipher. Modern smartphones automatically encrypt stored data, but you must activate full-device encryption if it’s not already enabled.
When accessing the internet, especially on public Wi-Fi, an online VPN ensures your data remains private. It encrypts your connection, preventing hackers from spying on your online activity. Choose a reputable VPN provider that doesn’t log your browsing history. If you frequently use public networks, a VPN is essential for keeping your information secure.
Enable Remote Wipe and Lock Features
Losing your phone doesn’t have to mean losing control of your data. Remote security features allow you to lock or erase your device before an unauthorised person gains access. Both iOS and Android devices offer built-in tools to track, lock and wipe lost or stolen phones. By setting up these protections in advance, you ensure that your personal information doesn’t fall into the wrong hands.
Practice Safe Connectivity
Public Wi-Fi networks are convenient but rarely secure. Attackers can set up rogue hotspots or intercept unencrypted connections to steal login credentials and personal data. Connecting to an unverified network without protection puts your information at risk.
Whenever possible, use mobile data instead of public Wi-Fi for sensitive transactions. If you must use a public network, activate a VPN to encrypt your connection. Turn off automatic Wi-Fi and Bluetooth connections to prevent your phone from linking to unknown networks without your knowledge. By staying vigilant about how and where you connect, you reduce the risk of cyber threats compromising your device.
