The endpoint sends an inquiry to the gateway and the gateway responds with the address of the DNS server.

It is manually configured in the network settings by the administrator or obtained from the DHCP server.

The endpoint sends out a DNS Discover broadcast request to all endpoints on the local network.

The DNS server is always located on the gateway.

The NIC forwards promiscuous packets to the Promiscuous Server.

The NIC filters out dangerous or “promiscuous” packets.

The NIC sends all packets to the CPU for processing instead of only those packets indicated for its MAC address.

The NIC sends out one false, or “promiscuous” packet for every legitimate packet it sends to interfere with eavesdropping operations.

1 point

Subsequent packets of the same session are automatically allowed.

Every packet is inspected and allowed or denied based upon the same firewall rules that applied to the first packet.

The subsequent packets are inspected based on session-specific rules, not the packet-specific rules that were used to inspect the first packet in the session.

Subsequent packets that arrive within the Session Interval configured for that firewall will be allowed to pass without inspection. The first packet that arrives after the session interval expires will trigger the creation of a new session.
