Final answer:
The correct technique is Packet Filtering, which inspects data packets at a firewall to determine whether to allow or block them based on pre-determined rules.
Step-by-step explanation:
The technique that stops data packets originating outside the organization, inspects them, and passes the packets to the other side of an organization's firewall is known as Packet Filtering. Packet filtering works at the network layer and is typically part of a firewall's functionality. It checks the headers of packets, applying a set of rules to determine whether to allow or block them based on their source and destination addresses, types of protocols used, ports, and more. Intrusion Detection Systems (IDS) monitor network traffic for suspicious activity. A Virtual Private Network (VPN) secures a private network connection over a public network. Network Address Translation (NAT) hides private IP addresses when devices are communicating with the internet.
