HTTPS (Hypertext Transfer Protocol Secure):
Description: HTTPS is a secure version of HTTP that uses SSL/TLS to encrypt data transmitted between the client and server.
Security: HTTPS provides strong encryption and security, making it resistant to eavesdropping and man-in-the-middle attacks. It is designed to protect data integrity and confidentiality.
HTTP (Hypertext Transfer Protocol):
Description: HTTP is used for transmitting data over the web but does not encrypt the data.
Vulnerability: HTTP transmits data in plain text, which makes it vulnerable to interception and attacks like man-in-the-middle attacks. However, it is generally less vulnerable than FTP due to its widespread use and the availability of HTTPS.
UDP (User Datagram Protocol):
Description: UDP is a connectionless transport layer protocol used for transmitting data. It does not provide built-in encryption or security features.
Vulnerability: While UDP lacks inherent security, its vulnerabilities are often addressed by implementing additional security measures at higher layers. It is generally considered less vulnerable than FTP in terms of data protection.
FTP (File Transfer Protocol):
Description: FTP is used for transferring files between clients and servers but transmits data in plain text, including usernames and passwords.
Vulnerability: FTP is highly vulnerable because it does not encrypt data, making it easy for attackers to intercept and access sensitive information, including credentials and transferred files.
FTP is the most vulnerable protocol among the options provided because it lacks encryption and security features, making it susceptible to various attacks such as eavesdropping and credential theft.
HTTPS is the most secure protocol, while HTTP and UDP have their vulnerabilities but are not as inherently insecure as FTP.
Hence, the correct answer is option d. FTP
