7 simple cybersecurity habits to protect your personal data

• Protect your personal data by using strong, unique passwords, enabling two-factor authentication and keeping your devices updated to reduce the risk of cyberattacks
• Be cautious of phishing scams, avoid using public Wi-Fi for sensitive activities and regularly review your privacy settings to limit unnecessary exposure online
• Backing up important files and practising good cybersecurity habits can help protect your accounts, finances and personal information from hackers and data loss

Your personal data is more valuable than you might think. From banking details and passwords to photos, emails and social media accounts, cybercriminals are constantly looking for ways to steal sensitive information.

The good news is that you don't need to be a cybersecurity expert to stay safe online. In many cases, practising a few simple habits can significantly reduce your risk of falling victim to scams, identity theft or hacking attempts.

Here are seven cybersecurity habits everyone should adopt to better protect their personal data.

1. Use strong, unique passwords

Your password is the first line of defence against cybercriminals.

Avoid using easy-to-guess passwords such as your name, birthday or "123456". Instead, create long passwords that combine uppercase and lowercase letters, numbers and special characters.

Just as importantly, don't reuse the same password across multiple accounts. If one account is compromised, reused passwords could give attackers access to your email, banking and social media profiles.

A password manager can help you generate and store strong passwords securely.

2. Turn on two-factor authentication (2FA)

Even the strongest password isn't foolproof.

Two-factor authentication adds an extra layer of security by requiring a second form of verification, such as a one-time code sent to your phone or generated by an authentication app.

If someone steals your password, 2FA makes it much harder for them to access your account.

Enable it on important accounts such as your email, banking apps, cloud storage and social media platforms.

3. Keep your devices and apps updated

Software updates do more than introduce new features—they often fix security vulnerabilities that hackers could exploit.

Enable automatic updates on your smartphone, computer, browser and apps whenever possible. Keeping your devices up to date is one of the simplest ways to protect yourself from known cyber threats.

Delaying updates could leave your devices exposed to avoidable risks.

4. Think before clicking links or downloading files

Phishing scams remain one of the most common forms of cybercrime.

Fraudsters often send fake emails, text messages or social media messages that appear to come from trusted organisations, asking you to click a link or download an attachment.

Before clicking, check the sender's email address, look for spelling mistakes and verify that the message is genuine. If something feels suspicious, visit the company's official website directly instead of using the link provided.

When in doubt, don't click.

5. Avoid using public Wi-Fi for sensitive activities

Free public Wi-Fi is convenient, but it isn't always secure.

Avoid logging into online banking accounts, making financial transactions or accessing confidential work documents while connected to public networks unless you're using a trusted Virtual Private Network (VPN).

If possible, use your mobile data or personal hotspot when handling sensitive information.

6. Review your privacy settings regularly

Many apps and social media platforms collect more information than users realise.

Take time to review your privacy settings and limit the amount of personal information you share publicly. Restrict unnecessary app permissions, such as access to your location, contacts, microphone or camera, unless they're genuinely required.

The less personal information you expose online, the harder it becomes for cybercriminals to exploit it.

7. Back up your important data

Cyberattacks, accidental deletion and hardware failures can happen without warning.

Regularly back up important files such as documents, photos and videos using cloud storage, an external hard drive or both. Having a recent backup ensures you can recover your data even if your device is lost, stolen or infected with ransomware.

A backup is your safety net when the unexpected happens.

Why cybersecurity matters

Cybersecurity isn't just a concern for businesses or IT professionals. Anyone with a smartphone, computer or internet connection can become a target.

Personal information can be used for identity theft, financial fraud, account takeovers and other forms of cybercrime. Developing safe online habits is one of the best ways to reduce these risks.

Small actions taken consistently can make a big difference.

How to protect yourself from online banking fraud in Nigeria

Meanwhile, TheRadar earlier compiled a detailed practical guide on how to protect yourself from online banking fraud in Nigeria.

With the growth of digital banking, scammers are using phishing messages, fake apps and social engineering to steal money and sensitive information from unsuspecting users.

Never share PINs, OTPs or passwords, and avoid clicking on suspicious links, as fraudsters often impersonate banks to trick users into revealing confidential information.

Use strong passwords, enable two-factor authentication, avoid public Wi-Fi for banking, and regularly check your account for unusual transactions to detect fraud early.
