How does the client verify the authenticity of a server's public key during the TLS handshake?
During the TLS handshake, the client verifies the authenticity of a server's public key using a combination of asymmetric encryption, digital certificates, and a trusted third party called a Certificate Authority (CA). This process ensures that the client is communicating securely with the intended server and not an imposter. When the client initiates a TLS

Why is authentication important in preventing man-in-the-middle attacks in TLS?
Authentication is a crucial aspect of preventing man-in-the-middle (MITM) attacks in the context of Transport Layer Security (TLS). TLS is a widely used cryptographic protocol that provides secure communication over the internet. It ensures the confidentiality and integrity of data exchanged between a client and a server. However, without proper authentication, an attacker can exploit
What is a Man-in-the-Middle (MITM) attack in the context of TLS and how does it compromise the security of web applications?
A Man-in-the-Middle (MITM) attack in the context of Transport Layer Security (TLS) is a malicious interception of communication between two parties, where an attacker secretly relays and possibly alters the information being exchanged. This type of attack compromises the security of web applications by exploiting the trust established through TLS encryption, allowing the attacker to

Why is TLS important in web application security and what are the potential risks associated with using HTTP instead of HTTPS?
Transport Layer Security (TLS) is crucial in web application security due to its ability to encrypt communication between a client and a server. It offers confidentiality, integrity, and authentication, making it an essential component for securing sensitive information transmitted over the internet. In contrast, using HTTP instead of HTTPS exposes web applications to various potential
