What protocol is used for secure data transmission in AWS?

The protocol used for secure data transmission in AWS is HTTPS, which stands for Hypertext Transfer Protocol Secure. HTTPS is the secure version of HTTP, where the 'S' stands for 'Secure', indicating that the data transmitted over this protocol is encrypted using Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). This encryption ensures that the data exchanged between the client and the server is protected from eavesdropping and tampering, which is crucial for maintaining privacy and security in web applications.

In AWS, utilizing HTTPS is essential when connecting to various services, as it safeguards sensitive information, such as credentials, personal data, and financial details, against interception. This is especially important in cloud environments, where data is often transferred over the internet.

Other protocols, such as FTP, HTTP, and SMTP, do not offer the same level of security as HTTPS. FTP is known for transferring files without encryption, making it unsuitable for secure communications. HTTP, while widely used for web traffic, lacks the encryption that HTTPS provides, leaving data vulnerable to attacks. SMTP is a protocol used for sending emails but does not inherently secure email content; secure versions of SMTP (like SMTPS) use encryption but are not directly relevant to the general data
