Whenever you’re online, you leave behind information about yourself. Websites collect details about your browsing habits all the time. It’s why that Dyson hairdryer that you Googled a week ago is now appearing in ads on your YouTube app. It’s why you see recommended reels from influencers that are similar to the ones you already follow.
But it’s not just websites that are tracking you. Cybercriminals look for opportunities to steal personal information or access your accounts. Before you consider buying specialist software to reduce these risks, take a look at the steps you can take to protect yourself online that won’t cost you a penny.
Strengthen your password and authentication habits
Account security is your main starting point. It’s essential you lock down your accounts and protect your digital privacy because if your login details are compromised, hackers have direct access to everything from your personal messages and financial files to whatever you’ve got stored on the cloud.
Weak or recycled log-in details expose you to automated credentials-guessing scripts and large-scale data breaches. The Information Commissioner’s Office (ICO) highlights that secure password systems must actively defend against password theft and credential-guessing attacks.
To protect your information, create unique passphrases for every single service rather than reusing familiar words. Reinforce the login process by activating two-factor authentication (2FA) across all your primary accounts. This extra layer verifies your identity through a secondary verification check before giving you access.
When an attacker steals your primary password, 2FA successfully blocks their entry attempts because they don’t have your physical phone or authentication token.
Review the privacy and security settings on your devices
Relying on factory default settings leaves your smartphones, tablets, and laptops broadcasting personal diagnostic data and location history back to hardware manufacturers.
Open the settings menu on your mobile phone right now, head to the privacy tab, and revoke non-essential location, camera, and microphone permissions for apps that don’t genuinely require them.
Your choice of web browser software also controls how effectively you block invasive third-party trackers. Switch your default browser settings to block third-party tracking cookies automatically and enable built-in automatic operating system updates across all your personal hardware.
Operating system updates release vital security patches that close newly discovered bugs in the system before cybercriminals can exploit them.
Protect your connection when using Wi-Fi
Connecting your laptop or smartphone to unverified wireless networks in public places exposes your live internet traffic to nearby bad actors.
Attackers sharing the same public or insecure Wi-Fi network can intercept unencrypted data traffic and monitor your live browsing sessions. Whenever you check emails or read news away from home, check your browser’s address bar to ensure every active website uses HTTPS encryption.
Avoid logging into sensitive personal services while connected to open coffee shop or airport networks. Instead, tether your laptop directly to your mobile phone’s personal hotspot connection, which routes your internet traffic through encrypted cellular networks.
Using a Virtual Private Network (VPN) can help protect your connection while you’re in public by encrypting your internet data so it appears scrambled to anyone trying to hack in. Search for a reputable free VPN options are available and provide high levels of security.
Make your home Wi-Fi more secure
Strengthening your personal home network is also essential. This prevents unauthorised external users from piggybacking on your internet connection.
Review your home router security settings. Update default passwords, set robust wireless security keys, and select the latest encryption option. Open your web browser and enter your router’s default IP address to open your network administration portal.
Immediately replace the factory-set administrative password with a unique, long passphrase. Next, inspect your router’s Wi-Fi security settings and ensure your wireless network uses modern WPA2-AES or WPA3 encryption rather than outdated standards.
By taking these steps, you can secure your data.
