A security consultant is helping an organization to enhance the detection capabilities of unauthorized activities within its internal network. The organization's security strategy includes the deployment of Network Intrusion Detection Systems (NIDS) but also emphasizes minimizing the impact on network performance. Which deployment strategy should the consultant recommend?
Deploy NIDS sensors in inline mode to actively moderate and filter traffic.
Configure NIDS sensors in tap/monitor mode to replicate the network traffic non-intrusively.
Place NIDS sensors in promiscuous mode to passively collect traffic without duplicating it.
Set up NIDS sensors to operate in stealth mode, invisible to network hosts and devices.
