[All ICS-SCADA Questions]

Which of the following names represents inbound filtering?

AFunnel

BSanity

CEgress

DIngress

Show Suggested Answer

Suggested Answer: D

Ingress filtering is a method used in network security to ensure that incoming packets are allowed or blocked based on a set of security rules.

This type of filtering is often implemented at the boundaries of networks to prevent unwanted or harmful traffic from entering a more secure internal network.

The term 'ingress' refers to traffic that is entering a network boundary, whereas 'egress' refers to traffic exiting a network.

I practiced a similar question, and I think "Funnel" might be a trick option. I’m leaning towards "Ingress" too.

I feel like "Egress" is related to outbound traffic, so that can't be it. I think "Ingress" is the best choice.

I think inbound filtering has something to do with traffic coming into a network, so maybe it's "Ingress"?

I think the answer is Ingress. That term sounds like it's referring to traffic coming into the network, which is what inbound filtering is all about.

Okay, let's see. Inbound filtering is about controlling what comes into a network, so I'm guessing the answer is either Ingress or Funnel.

Ingress is the way to go. Unless you're trying to be fancy and call it 'the great filter of doom', in which case I guess Funnel would work too.
