What are the disadvantages of the DNS CNAME record?
The DNS (Domain Name System) is a critical component of computer networking that translates human-readable domain names into IP addresses. It plays a crucial role in establishing connections between devices on the internet. DNS CNAME (Canonical Name) records are a type of DNS record that allows one domain name to be an alias for another

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

What are the vulnerabilities associated with the DNS system, and how can attackers exploit them to redirect users to malicious servers?
The Domain Name System (DNS) is a fundamental component of the internet infrastructure that translates human-readable domain names into IP addresses. While DNS plays a crucial role in facilitating communication between clients and servers, it is not immune to vulnerabilities. Attackers can exploit these vulnerabilities to redirect users to malicious servers, leading to various security
