Question about DDoS...
I am learning about DDoS attacks and all that kind of stuff, so I've started to gain more questions then answers.This is about UDP TCP layer.
- Why closed port cannot be attacked?
- Why filtered port is better then closed?
- Why is it better to have filtred ports?
- If the server usses 22005 port for connections, is there need to filter other ports or is it fine if they are not filtered?
