Which security technology can provide secure network communications from on-site enterprise systems to a cloud platform?

Internet Protocol Security (IPSec) virtual private network (VPN) is the appropriate technology for ensuring secure network communications from on-site enterprise systems to a cloud platform. IPSec is a comprehensive suite of protocols designed to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet in a communication session.

When utilized as a VPN, IPSec creates a secure tunnel over the internet, allowing data to be transmitted safely between the enterprise systems and the cloud service. This tunnel encrypts the data packets, ensuring that even if they are intercepted, they cannot be read by unauthorized entities. Additionally, IPSec supports various authentication mechanisms, providing assurance that the data is sent and received by legitimate parties.

In contrast, the other technologies listed serve different purposes. Domain Name System Security Extensions (DNSSEC) helps protect against certain types of attacks related to DNS queries, but it does not secure the data in transit. A Web Application Firewall (WAF) mainly focuses on protecting web applications by filtering and monitoring HTTP traffic between web applications and the Internet, rather than securing network-level communication. Data Loss Prevention (DLP) technologies are aimed at preventing data breaches and ensuring sensitive information is not shared or lost, but they do not specifically provide secure transport of
