What is Encrypted DNS?

Secure Your Online Activity with Encrypted DNS: The Importance of DNS Security and DNS over HTTPS (DoH)

Encrypted DNS, often referred to as DNS over HTTPS (DoH), is a relatively new modulation of the Domain Name System protocol. It has an added cloak of security around it, serving to protect internet browsing activities from eavesdropping and manipulation by outsiders. To understand how DNS and Internet connections work, we'll first need to understand the background.

The Domain Name System (DNS) is a critical aspect of how the internet functions, since it connects URLs or web addresses that humans can comprehend, to IP addresses that computers and servers can understand. Imagine you're trying to access a website like 'www.xyz.com'. To take you there, your browser needs to recognize its IP address, say '173.194.39.78'. The standard DNS service plays the role of the translator between the human-specified 'www.xyz.com' and the computer-understandable IP address '173.194.39.78', making your internet navigation seamless.

As the online experiences have made regressive leaps and bounds, it has led to increased threats to cybersecurity. The infrastructural components of the internet we trust are emerging as potentially exploitable weak spots. Our browsing data can be susceptible to an array of potential hazards if the communication between our web browser and the DNS translator isn't secure. That's precisely where Encrypted DNS comes into play.

Encrypted DNS signifies a fundamental shift in the working of the typical DNS protocols, which traditionally have always been non-encrypted. This meant that anyone who wanted to intercept the DNS requests or spoof a DNS response to mislead the browser could do so quite conveniently. the encrypted DNS, particularly aka DoH, encrypts the DNS queries, making them practically unreadable and untraceable by anyone during transit. It does this using the HTTPS protocol.

Therefore, by encoding the DNS data, Encrypted DNS prevents any spying eyes from discerning what site an individual is wishing to visit by looking at their internet traffic. with encryption, it's difficult for hackers to reroute users to other deceptive or scam sites, which is known as a manipulation technique called a 'man-in-the-middle attack.' This safeguard is incredibly valuable for maintaining privacy and preventing any phishing attempts.

From a cybersecurity standpoint, having an encrypted DNS is particularly important. Cybersecurity tools like antiviruses are rendered more effective by the implementation of DoH. This security protocol works cooperatively with an antivirus by essentially shielding web browsing data from potential online threats. While antivirus keeps the device secure by warding off attacks, encrypted DNS protects user data during browsing. Effectively, it provides an additional layer of protection.

While an effective escape from most third parties breaking into or faking your DNS requests, this doesn't make Encrypted DNS an absolute cure for all online security issues. Storing all DNS data with one provider invariably presents a central target for hackers also to be wary of some Internet Service Providers offering DoH, which says they cannot eavesdrop themselves, but does not prevent the data collected from being used against user interests.

As online activities continue progressing towards the integration of more robust security measures undoubtedly, the Encrypted DNS enhances the user's trust in secured browsing sessions. It makes an effective case for more privacy, less targeted advertising, and notably, a safer online environment.

Encrypted DNS or, more specifically, DNS over HTTPS, is an evolving tool in the cybersecurity and antivirus arenas. By providing encrypted connections, it provides an added layer of security, cutting off potential vulnerabilities and increasing the safety of our digital personal lives, one encrypted domain at a time.
