Many tools and technologies are available for securing or monitoring data in transit within a data center, whether it is a traditional data center or a cloud.
Which of the following is NOT a technology for securing data in transit?
Click on the arrows to vote for the correct answer
A. B. C. D.C.
DNSSEC is an extension of the normal DNS protocol that enables a system to verify the integrity of a DNS query resolution by signing it from the authoritative source and verifying the signing chain.
It is not used for securing data transmissions or exchanges.
VPNs are widely used for securing data transmissions and service access.
The answer to the question is C. DNSSEC is not a technology for securing data in transit.
Explanation:
A. VPN (Virtual Private Network): A VPN provides a secure connection between two devices or networks over the internet. It creates an encrypted tunnel that encapsulates data in transit between two endpoints. This technology is widely used to secure data in transit between networks.
B. TLS (Transport Layer Security): TLS is a cryptographic protocol used to secure data in transit over the internet. It is used to encrypt data between two endpoints to prevent eavesdropping, tampering, or data theft. TLS is commonly used to secure HTTP traffic, and it is also used in other protocols such as SMTP, FTP, and IMAP.
C. DNSSEC (Domain Name System Security Extensions): DNSSEC is a set of extensions to the Domain Name System (DNS) protocol. It provides a way to validate the authenticity of DNS records to prevent DNS spoofing attacks. However, DNSSEC does not provide any encryption or confidentiality for data in transit.
D. HTTPS (Hypertext Transfer Protocol Secure): HTTPS is an extension of HTTP that adds encryption and authentication to the protocol. It uses TLS to secure data in transit between a client and a server. HTTPS is commonly used to secure web traffic, and it provides a way to protect sensitive information such as passwords, credit card numbers, and other personal information.
In summary, all the options except C (DNSSEC) are technologies that are used to secure data in transit. VPN, TLS, and HTTPS provide encryption and confidentiality, while DNSSEC provides data authenticity.
