Question 36

TLS 1.3 is the most appropriate way to protect data in transit.

TLS 1.3 is a cryptographic protocol designed to provide secure communication over a computer network, making it the best choice for protecting data in transit.

A) SHA-256

SHA-256 is a cryptographic hash function that produces a 256-bit hash value. While it is useful for verifying data integrity, it does not provide encryption or secure transmission capabilities, making it unsuitable for protecting data in transit.

B) SSL 3.0

SSL 3.0 is an older protocol for securing communication over a network. It has known vulnerabilities and has been deprecated in favor of more secure protocols like TLS 1.3, which provide improved security features and better protection for data in transit.

C) TLS 1.3

TLS 1.3 offers enhanced security features and improved performance over previous versions of the TLS protocol. It provides robust encryption and ensures the confidentiality and integrity of data transmitted over the network, making it the most appropriate method for protecting data in transit.

D) AES-256

AES-256 is an encryption standard used to secure data at rest or in transit. However, by itself, it does not establish a secure communication channel. Without a protocol like TLS to manage the encryption during transmission, AES-256 cannot solely protect data in transit.

Conclusion

TLS 1.3 stands out as the most effective option for protecting data in transit due to its comprehensive encryption and security features. Other options, while relevant in different contexts, either lack the necessary capabilities for secure transmission or are outdated and vulnerable, underscoring the superiority of TLS 1.3 in ensuring secure data communication.
