In my Network Security class were talking about DoS attacks and the three methods of DoS Attacks:

1.Direct/Indirect

2.Intermediary

3.Reflected

The three questions I need help on:

1) If im trying to bring Joe's server down, what is that called?

2) If im spoofing Michael's IP address, what is that called?

3) If the responses are going somewhere else, what is that called?
