i need ur help, i read in networking and some security on it, i have problem when i read that, it is:
i know that UDP is unrealiable , so i think that mean it has no 3-way hand shaking,
but when i read many papers, it said that UDP can be checked (by authantic method) in the first request packet, and if it not auth. the whole traffic is discard!!!!
please how is that??
doesn't the packets reach the destination out of order? so how can we recognize the first request packet from other packets?
and how to recognize the whole flow of that request?
thank u very much for any help
