Security Technologies for Data in Transit

A.

DNSSEC relates to the integrity of DNS resolutions and the prevention of spoofing or redirection, and does not pertain to the actual security of transmissions or the protection of data.

Out of the given options, the technology that is not commonly used for security with data in transit is DNSSEC (A). The other options, IPsec, VPN, and HTTPS, are all commonly used for securing data in transit.

IPsec (Internet Protocol Security) is a protocol suite used to secure communication over the internet. It provides encryption, authentication, and integrity to protect data packets sent over an IP network.

VPN (Virtual Private Network) is a technology used to create a secure connection between two networks over the internet. It creates a private and encrypted tunnel between the two networks, ensuring that data in transit is secure.

HTTPS (Hypertext Transfer Protocol Secure) is a protocol used to secure communication over the internet. It provides encryption, authentication, and integrity to protect data transmitted between a web server and a web browser.

DNSSEC (Domain Name System Security Extensions) is a security protocol that is used to protect the domain name system (DNS) from attacks like DNS cache poisoning. It does not directly provide security for data in transit, but rather it ensures that the DNS responses received by the client are authentic and have not been modified by a malicious actor.

In conclusion, DNSSEC is not commonly used for security with data in transit, while IPsec, VPN, and HTTPS are commonly used.
