The data transfer will be done over TCP 20. Similarly, which of the following is described as the combination of an IP address and a port number? In the standard Internet protocols TCP and UDP, a socket address is the combination of an IP address and a port number, much like one end of a telephone connection is the combination of a phone number and a particular extension.What type of attack are stateless packet filters particularly vulnerable to?
