Final answer:
The subject is likely a network security device that monitors and allows only authorized traffic to the corporate network by acting like a gateway or filter.
Step-by-step explanation:
The statement "__ only captures traffic destined for the corporate network" is likely referring to a network security device or software that is designed to monitor and secure data traffic within a corporate environment. These devices usually function as gateways or filters to ensure that only authorized traffic is able to access the network's resources. Examples include firewalls, Virtual Private Network (VPN) concentrators, and intrusion detection systems (IDS). Such devices have configurations that define what constitutes "destined for the corporate network" traffic, and they are designed to create a secure perimeter to protect sensitive data and resources.
Network devices such as routers or firewalls filter and capture traffic that is destined for the corporate network.
For example, when traffic passes through a router, it examines the destination IP address and determines if it matches the corporate network's IP range. If it does, the router captures the traffic and forwards it to the appropriate internal network. If the destination IP address is outside the corporate network, the router does not capture the traffic.
