Explanation:
DNSSEC is used as a security extension to DNS lookup queries in order to ensure the authenticity and authoritativeness of hostname resolutions, in order to prevent spoofing and redirection of traffic. Although it is a very important concept to be employed for security practices, it is not used to secure or encrypt data transmissions. HTTPS is the most commonly used security mechanism for data communications between clients and websites and web services. IPSec is less commonly used, but is also intended to secure communications between servers. VPN is commonly used to secure traffic into a network area or subnet for developers and administrative users.
