A security administrator needs to deploy an Intrusion Detection System (IDS) on a critical network segment. The primary requirement is that the appliance must only observe traffic for analysis and reporting. It should not introduce any latency or become a point of failure for the live traffic. Which device attribute is required for this deployment?
A passive device attribute allows the network appliance to observe traffic without interacting or making changes to it, enabling monitoring and analysis without affecting data flow. This contrasts with an active device, which is designed to interact with or change the traffic passing through it, performing actions such as blocking or modifying packets.
