Discuss the implications of not encrypting DNS requests in the context of TLS and web application security.
In the context of web application security, the implications of not encrypting DNS (Domain Name System) requests can be significant. DNS is a fundamental protocol that translates domain names into IP addresses, allowing users to access websites using human-readable names instead of numerical IP addresses. When DNS requests are not encrypted, they can be intercepted

What is DNS hijacking and how does it bypass the Same Origin Policy?
DNS hijacking refers to the malicious act of redirecting DNS (Domain Name System) queries to unauthorized servers, thereby enabling an attacker to intercept and manipulate network traffic. This technique exploits vulnerabilities in the DNS infrastructure, allowing the attacker to control the resolution of domain names to IP addresses. By doing so, the attacker can redirect
What is the role of DNS in web protocols, and why is DNS security important for protecting users from malicious websites?
The Domain Name System (DNS) plays a crucial role in web protocols, acting as a fundamental component of the internet infrastructure. It serves as a distributed database that translates human-readable domain names into machine-readable IP addresses, enabling the communication between clients and servers on the internet. DNS is essential for the functioning of web protocols

Why understanding of web protocols and concepts such as DNS, HTTP, cookies and sessions is crucial for web developers and security professionals?
Understanding web protocols and concepts is crucial for web developers and security professionals to ensure the proper functioning and security of web applications. In this context, implementing secure DNS practices, handling HTTP headers correctly, and managing sessions and cookies properly can significantly enhance the security of web applications and protect user data. Let's start by
