As we navigate an increasingly digital world, safeguarding not just our devices but also our data and privacy becomes paramount. Cyber threats are evolving, targeting the networks we connect to and the data we transmit and store.
This article deep dives into securing your mobile devices and Wi-Fi networks, implementing encryption to protect your data in transit and at rest, and utilising Virtual Private Networks (VPNs) to enhance your online privacy and security.
How to safely use public and home Wi-Fi networks
Public Wi-Fi networks are convenient but often not secure. They can expose you to eavesdropping, man-in-the-middle attacks, and other threats.
When using public Wi-Fi, there are several precautions you can take to protect your information:
Use a VPN: A Virtual Private Network (VPN) encrypts your internet traffic, protecting your data even on unsecured networks. Always connect to a VPN before accessing sensitive information on public Wi-Fi.
Avoid Sensitive Transactions: Refrain from performing sensitive transactions, like banking or shopping, on public Wi-Fi unless absolutely necessary and through a VPN.
Your home Wi-Fi network also requires attention to ensure it’s secure from external threats.
Admin Password: Change the default admin password for your router to a strong, unique password to prevent unauthorised access.
Network Name (SSID): Modify the default SSID to something unique that doesn’t give away personal information or the router model.
WPA3 Encryption: Ensure your router is set to use WPA3 encryption, the latest standard for Wi-Fi network security. This can usually be selected in the router’s settings menu.
Wi-Fi Protected Setup (WPS): While convenient, WPS can be a security risk. Disable this feature in your router’s settings to protect your network.
Encryption: Protect your data in transit and at rest
Encryption acts as a digital vault for your data, transforming it into a format that can’t be read without the correct decryption key. Whether your data is being sent across the internet or sitting on your device, encryption ensures it remains private and secure.
Encrypting your device is one of the most effective ways to protect your data at rest. Most modern devices come with built-in encryption capabilities that can be easily enabled.
For Android Devices:
Settings: Navigate to the Settings app and scroll down to “Security.”
Encryption: Look for an option that says “Encrypt phone” or “Encrypt storage.” If your device is new, it may already be encrypted by default.
Follow the Prompts: Begin the encryption process by following the on-screen instructions. Note that initial encryption can take an hour or more, during which your device should remain charged and powered on.
For iOS Devices:
Enable Passcode: Go to Settings > Touch ID & Passcode (or Face ID & Passcode on newer models). Setting up a passcode automatically enables data encryption.
Passcode Settings: Follow the prompts to create a strong passcode. Once set, the encryption is active as long as the passcode is enabled.
How to use encrypted communication apps
For data in transit, utilising communication apps that offer end-to-end encryption ensures that your messages, calls, and data transfers remain private.
Messaging Apps: Applications like Signal and WhatsApp provide end-to-end encryption for messages and calls, meaning only you and the recipient can read or listen to them, not even the service providers.
Email Encryption: Services like ProtonMail offer encrypted email communication, safeguarding the content of your emails from interception.
VPNs are a critical tool for securing your online activities, especially when using public Wi-Fi or accessing sensitive information. They encrypt your internet connection, making your online actions virtually invisible to eavesdroppers and protecting your data from interception.
Selecting a reputable VPN service is crucial for effective protection. Consider the following when choosing a VPN provider:
Privacy Policy: Opt for providers with strict no-logs policies, ensuring they don’t track or store your online activities.
Security Features: Look for VPNs offering robust encryption standards, such as AES-256, and additional features like a kill switch, which disconnects you from the internet if the VPN connection drops.
Reputation and Reviews: Research user reviews and expert opinions to gauge the reliability and performance of the VPN service.
Setting up a VPN varies by provider, but most follow a similar process:
Select a VPN Provider: Choose a VPN service that meets your privacy and security needs.
Download and Install: Download the VPN application from the provider’s website or the app store, and install it on your device.
Sign In: Open the app and sign in with your account details.
Connect to a Server: Select a VPN server location and connect. Your internet connection is now encrypted, and your online activities are secure.
Best practices of using VPN
Always-On: Keep your VPN enabled whenever you’re online to ensure continuous protection.
Wi-Fi Networks: Always use your VPN on public Wi-Fi networks to encrypt your connection.
Sensitive Transactions: Engage your VPN when performing sensitive activities, like online banking or shopping, to secure your data.
By adopting secure Wi-Fi practices, implementing encryption, and utilising VPNs, you significantly enhance the protection of your data and privacy. These measures act as a shield against cyber threats, ensuring that your personal and sensitive information remains confidential in an ever-evolving digital landscape.
