DNS over HTTPS vs. DNS over TLS: Enhancing Online Privacy in 2024

In the ever-evolving landscape of internet security, understanding and implementing advanced technologies like DNS over HTTPS (DoH) and DNS over TLS (DoT) is crucial. This detailed guide provides insights into these protocols, helping you secure your online activities in 2024.

Understanding the Basics

What is DNS?

DNS (Domain Name System) is the phonebook of the internet, translating domain names into IP addresses. However, traditional DNS queries are not encrypted, posing privacy and security risks.

The Need for Secure DNS

As cybersecurity threats escalate, encrypting DNS queries becomes essential to prevent interception and manipulation by malicious actors.

DNS over HTTPS (DoH)

How Does DoH Work?

DoH enhances privacy by sending DNS queries over the secure HTTPS protocol. This encrypts the data between your device and the DNS resolver, shielding it from prying eyes.

Implementing DoH

Step 1: Choose a DoH-Compatible Browser

Most modern browsers like Chrome, Firefox, and Edge support DoH. Ensure your browser is up to date.

Step 2: Enable DoH in Browser Settings

Navigate to your browser’s privacy or network settings and select the option to enable DNS over HTTPS.

Step 3: Select a Trusted DoH Resolver

Pick a DoH DNS resolver from a reputable provider for enhanced security.

DNS over TLS (DoT)

Understanding DoT

DNS over TLS is similar to DoH but operates over the TLS (Transport Layer Security) protocol. It encrypts DNS queries at the transport layer, ensuring secure communication.

Setting Up DoT

Step 1: Verify Device Compatibility

Ensure your device or router supports DNS over TLS.

Step 2: Configure Network Settings

Access your device’s network settings and input the details of a DoT-compatible DNS server.

Step 3: Test the Configuration

Verify the setup by checking if your DNS queries are encrypted.

Comparing DoH and DoT

Similarities

• Both encrypt DNS queries.
• They enhance privacy and security.

Differences

• DoH uses HTTPS, blending with regular web traffic, which can be advantageous for bypassing certain network restrictions.
• DoT operates on a separate port and may be easier to block by networks that restrict non-HTTPS traffic.

Best Practices for Secure Browsing

Stay Informed

Keep up-to-date with the latest developments in DNS security.

Regularly Update Software

Ensure your browsers and devices are regularly updated for optimal security.

Choose Reputable Providers

Select DNS providers known for their commitment to privacy and security.

Conclusion: Secure Your Online Presence

By understanding and utilizing DNS over HTTPS and DNS over TLS, you significantly enhance your online privacy and security. As the digital world continues to evolve, staying informed and proactive about such technologies is crucial for safe browsing in 2024 and beyond.

Embrace the future of internet security with confidence. Implementing DoH or DoT is a significant step towards protecting your digital footprint. Stay safe, secure, and ahead in the world of online privacy.
