A municipal data center needs visibility into east-west traffic between application tiers so an IDS can detect lateral movement. Where should sensors be placed to support that goal?
Select an answer to reveal the explanation.
Short Explanation
East-west is the sideways chatter between servers—lateral movers love that hallway. Sensors have to sit on those internal paths or the IDS is staring at the front door while the thief walks room to room. Edge-only watching misses the inside game.
Full Explanation
IDS/IPS effectiveness depends on sensor placement on relevant traffic paths. East-west visibility requires sensors that see inter-tier or inter-server traffic inside the data center, not only north-south Internet edge flows. Ignoring internal traffic leaves lateral movement undetected. Printer VLAN mirroring and paper audits do not substitute for properly placed network sensors feeding IDS.
