Re: Why TCP is more secure than UDP?

Hi 

I dont understand what you mean by spoofing, since wherever you use UDP or TCP the underlying layer still remains IP so 
when you spoof a source you spoof an IP source.
If you talk about a man-in-the-middle attack then taking a closer look at both protocols will show that UDP doesnt 
establish any connection before starting the communication.
Using TCP you`ll need to ACK incomming data using a pre-established sequence number which makes the attack on TCP 
harder but not impossible.
