Which of the following components refers to a node in the network that routes the traffic from a workstation to external command and control server and helps in identification of installed malware in the network?
A gateway in a network functions as a node that routes traffic between different networks, such as from a local network to the internet. In the context of cyber threats, a gateway can be utilized to monitor and control the data flow to and from the network, helping in the identification and analysis of malware communications, including traffic to external command and control (C2) servers. This makes it an essential component in detecting installed malware within a network by observing anomalies or unauthorized communications at the network's boundary. Unlike repeaters, hubs, or network interface cards (NICs) that primarily facilitate network connectivity without analyzing the traffic, gateways can enforce security policies and detect suspicious activities.References:
