ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

A security engineer must add an open-source network IDS to monitor all traffic entering the company's DMZ. Management insists that the new device must not introduce latency or become a single point of failure. Which deployment strategy best meets these requirements while keeping the IDS in passive mode?

  • Cascade the IDS transparently between the perimeter firewall and the DMZ switch using two bridged interfaces.

  • Attach the IDS to a switched port analyzer (SPAN) port on the DMZ switch that mirrors all inbound and outbound packets.

  • Replace the existing edge router with the IDS configured to perform routing and inspection.

  • Configure every DMZ host to route its traffic through the IDS acting as an explicit proxy.
