1. Secure Your Screen with a Lock
The first line of defense is a screen lock. This simple yet crucial step prevents unauthorized access to your computer, especially when you're away from your desk, particularly in public spaces. Leaving your laptop unlocked is an open invitation to snooping eyes.
Setting up a screen lock on most Linux distributions is a breeze. Popular choices like Mint and Ubuntu, mirroring the ease of Windows or Apple, have this feature readily available. Just set a password, typically aligning with your system password, and your screen will lock after a predefined idle period.
The default interval is often 15 minutes, which is a tad excessive. Consider shortening it to five minutes, striking a balance between minimal disruption and effective security. In Ubuntu, this setting is found under "Privacy" within System Settings. Mint users can access it by typing "Screensaver" in the start screen.
For even greater security, lock your screen whenever you step away from your laptop. This is usually achieved by pressing Ctrl+Alt+L, although you can customize this shortcut in Linux.
2. Embrace the Power of VPNs
Another vital step towards a more private Linux laptop is installing a virtual private network, better known as a VPN. This handy tool redirects your connection while encrypting it within a VPN tunnel. Essentially, you can browse the web as if you were in a different location, making it much harder for others to track your online activities.
VPNs are powerful tools, but not all VPNs are created equal, especially for Linux. ExpressVPN, for instance, is only accessible via the terminal, while NordVPN is entirely incompatible. However, my personal favorite, Mullvad, works flawlessly, as does How-to Geek's office favorite, Proton VPN.
3. Switch to Private DNS Servers
While VPNs are excellent, they're not always the perfect solution. They come with a price tag, especially the good ones (steer clear of free VPNs), and can slow down your connection. If you're primarily concerned about surveillance from your internet service provider (ISP) and want to ensure they can't see your browsing activities, switching to private DNS servers is a good alternative.
When you connect to a website, your request first goes to a DNS server, which translates the website's URL (like www.howtogeek.com) into its corresponding IP address. These records are public and can be used by your ISP to track your browsing habits.
To avoid this, route your DNS requests through one of these private DNS servers. Access your Network Settings, select the connection you want to redirect (this must be done separately for each network, so once for home, once for work, etc.), and then enter the new private DNS you want to use.
4. Navigate the Web with Privacy-Focused Browsers
Finally, always use a privacy-conscious browser. While there's debate about which browser offers the ultimate privacy, one thing is clear: Google Chrome should be avoided. It has numerous privacy issues.
Most Linux distributions come pre-installed with Mozilla Firefox, putting one of the best browsers at your fingertips. Alternatives include Brave and Mullvad's browser; all offer significantly better privacy, although remember that using private browsing and a VPN are essential to maximize their effectiveness.
Why Privacy Matters
You might be wondering why privacy is so crucial. In today's digital age, your personal information is a valuable asset. By tracking your online activities, companies and governments can target you with ads, manipulate your behavior, or even restrict your freedoms.
By taking steps to protect your privacy, you maintain control over your personal data and ensure you can use the internet safely and freely.
Conclusion
Enhancing privacy on your Linux laptop isn't a complex endeavor. By following these simple yet effective tips, you can significantly improve your computer's security and safeguard your personal data. Remember, privacy is a fundamental right, and everyone deserves to keep their personal information secure.
