In this problem we'll explore the impact of NATS on P2P applications. Suppose a peer with username Arnold discovers through querying that a peer with username Bernard has a file it wants to download. Also suppose that Bernard and Arnold are both behind a NAT. Try to devise a technique that will allow Arnold to establish a TCP connection with Bernard without application specific NAT configuration. If you have difficulty devising such a technique, discuss why.

Question

In this problem we'll explore the impact of NATS on P2P applications. Suppose a peer
with username Arnold discovers through querying that a peer with username Bernard
has a file it wants to download. Also suppose that Bernard and Arnold are both behind a
NAT. Try to devise a technique that will allow Arnold to establish a TCP connection with
Bernard without application specific NAT configuration. If you have difficulty devising
such a technique, discuss why.

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:

Draw a sequence diagram for the following scenario. In a network, two nodes communicate with each other. These are the sequence. 1) Node J sends ping message to Node L 2) Node L sends ICMP echo reply to node L. Now Node A is having the MAC address of Node L. 3) Node J starts TCP handshake with Node L by sending SYN message. 4) Node L sends (SYN+ACK) back to node J. 5) Node J sends the ACK to Node L.

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.
Tracing through Layers Given the following scenario, trace out the path the packets will follow in the diagram provided. An alternate method of specifying your answer is given that requires no drawing Scenario: Your laptop A opens a web page from the server F, and the web caching server keeps a copy of the page on its way back to you. A second user A' (who takes your place on the diagram) is on the same LAN as you, connected also to Router B, and opens the same web page. Draw the path the HTTP message requesting the page would take from its origin point at A' to its destination point where the packet would go no further. See diagram for more info
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)?
10 For a Smurf attack, we know the amplification factor = (total response size)/(request size).For example, a group of adversaries uses 'Dumb' protocol to conduct a Smurf attack. In the 'Dumb' protocol, a request containing 56 bytes results in 500 bytes of response. Assume that 150 devices are running this 'Dumb' protocol in a network. The devices are connected to the Internet through a single gateway. What would be the amplification factor for 'Dumb' protocol if we conduct the Smurf attack using the devices in the above network?
