CompTIA DataSys+ (DS0-001)Data and Database SecurityEasy
An organization is migrating its on-premise database to a cloud provider. They need to ensure that database connections from client applications to the cloud database are encrypted to prevent eavesdropping and data tampering during transmission. Which protocol is most commonly used to secure data in transit for database connections?
- AUDP (User Datagram Protocol)
- BHTTP (Hypertext Transfer Protocol)
- CTLS (Transport Layer Security)
- DFTP (File Transfer Protocol)
Show answer & explanationAnswer & explanation
Correct answer: C. TLS (Transport Layer Security)
TLS (Transport Layer Security) is the standard cryptographic protocol used to establish secure communication channels over a computer network. It encrypts data in transit, ensuring confidentiality, integrity, and authenticity for applications like database connections, web browsing (HTTPS), and email.
Why the other options are wrong
- A. UDP is a connectionless protocol that offers no inherent security or encryption.
- B. HTTP is an unencrypted protocol; its secure version, HTTPS, uses TLS.
- D. FTP is an unencrypted protocol for file transfers; SFTP or FTPS (using TLS) are secure alternatives.
Transport Layer Security (TLS)
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communication security over a computer network. It is widely used for encrypting communications between web applications and servers, mail servers, and database clients and servers.
- Successor to SSL.
- Provides encryption, authentication, and integrity.
- Operates at the transport layer (Layer 4) of the OSI model.
Memory trick: TLS secures the data journey.
