What are the different stateless and stateful methods for dynamic IPV6 configuration? How does this depend on the flags in the ICMPV6 RA message?

Three-way handshake is used by a TCP client and a TCP server to establish a connection, as illustrated below: 1st: client:port1 -> server:port2, SYN 2nd: server:port2 -> client:port1, SYNACK 3rd: client:port1 -> server:port2, ACK When this client is performing scanning attacks, it will generated a large number of failed connections. In each failed connection, the three-way handshake fails to complete. People commonly use SYN together with the absence of its corresponding SYNACK in this same TCP session to identify whether this connection is failed. By investigating the failed connections, an engineer finds that in legitimate/benign cases, if the server does not return SYNACK to the client, the client will not send the ACK packet after SYNACK (e.g., the 3rd packet above). Therefore, this engineer suggests that we can count the failed connections based on the following rules without considering SYNACK:

Question P  .Full explain this question and text typing work only     We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line

In HTTP version 1.0, a server marked the end of a transfer by closing the connection. Explain why, in terms of the TCP layer, this was a problem for servers. Find out how HTTP version 1.1 avoids this. How might a general-purpose request/reply protocol address this?

I was wondering if you could highlight the key differences between TCP session hijacking and UPD session hijacking.

Please just give a brief explanation about these cybersecurity questions.( Not more than three sentences).

Why is the 'Host' property included in the communication that is outlined by the HTTP1.1 protocol standard if it doesn't serve any purpose? Why is it that this cannot be determined from the L3 IP address in its present state?

When a web client requests access to a web server's protected resources, show how native authentication and authorization services are used. To solve this problem, it is easiest to look at the following two justifications for layered protocols: Please provide concrete examples to support your arguments.

We explore whether either UDP or TCP offers any level of end-point authentication in this problem. a. Consider a server that accepts a request via UDP and responds via UDP (for example, as done by a DNS server). Where would the server give its answer if a client with IP address X spoofs it with address Y? b. Assume a server receives a SYN with IP source address Y and responds with SYNACK. The server then receives an ACK with IP source address Y and the right acknowledgmentamount. Assuming the server selects a random initial sequence number and there is no "man-in-the-middle," how can the server be confident that the recipient is really at Y (and not at any other address X that spoofs Y)?
