I remember studying something about "source verification" techniques, but I can't recall the exact term.

I think the term we're looking for is "packet filtering," but I'm not entirely sure if that's specific enough.

Ah, I know this one! It's got to be something like source address validation or network origin authentication. Gotta make sure those packets are legit, you know?

Packet validation? Source authentication? I'm a bit unsure, but I think it has to do with confirming the origin of network traffic. I'll need to review my notes on network security concepts.

Okay, I've got this. This is asking about a technique to ensure the packets are coming from the right networks. I'm pretty confident it's something like source address verification or IP address validation.

Ugh, I'm not totally sure about this one. Packet authentication? Verifying network origins? I'll have to think it through carefully.
