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'm not sure, but I think C) Egress is for outgoing traffic.

Sanity? That's just asking for trouble. I'm pretty sure the correct answer involves something more technical-sounding, like Ingress.

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.

Egress? Really? That sounds more like outbound filtering to me. I'm going with Ingress on this one.

Ingress, for sure. The name just screams 'incoming traffic control' to me. Easy peasy.

Sanity and Egress don't really give off the same vibe as Ingress for inbound filtering.

Hmm, I'm pretty sure inbound filtering is represented by 'Ingress'. That's the one that sounds the most like it's filtering stuff coming in, you know?
