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.

A denial-of-service (DoS) attack against the FTP server 192.168.56.1 has been reported. Prior to the FTP service being taken down, there were significant increases in FTP traffic. This link will provide to you a network packet capture that has been captured.Is it possible to identify the IoCs of this case from the viewpoint of an investigator?Synthesize the appropriate filters that may be utilized to finish your research and answer the following questions by using the packet capture analysis technique. What was the source of the sudden increase in FTP traffic?What happened in the hours and minutes before the FTP site was taken offline?Any files were transmitted to or from the FTP server, and were any user accounts compromised as a result of this?
- Consider another carelessly written Web application, which uses a servlet that checks if there was an active session, but does not check if the user is authorized to access that page, instead depending on the fact that a link to the page is shown only to authorized users. What is the risk with this scheme? (There was a real instance where applicants to a college admissions site could, after logging into the Web site, exploit this loophole and view information they were not authorized to see; the unauthorized access was however detected, and those who accessed the information were punished by being denied admission.)
In this problem we investigate whether either UDP or TCP provides a degree of end-point authentication. a. Consider a server that receives a request within a UDP packet and responds to that request within a UDP packet (for example, as done by a DNS server). If a client with IP address X spoofs its address with address Y, where will the server send its response? b. Suppose a server receives a SYN with IP source address Y, and after responding with a SYNACK, receives an ACK with IP source address Y with the correct acknowledgment number. Assuming the server chooses a random initial sequence number and there is no "man-in-the-middle," can the server be certain that the client is indeed at Y (and not at some other address X that is spoofing Y)?
Q5. DHKE protocol Use these toy parameters to demonstrate how DHKE (Diffie-Hellman Key Exchange) works: a large prime number p key a = 5, Bob's secret key b = 4. What are their public keys? How can they come up with an agreed session key at the end of the protocol and what is the agreed session key? = 13 and a generator g = 2, (p and g are in public domain), Alice's secret %3=
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:

As presented in the text, SMTP involves the exchange of several small messages. In most cases, the server responses do not affect what the client sends subsequently. The client might thus implement command pipelining: sending multiple commands in a single message. (a) For what SMTP commands does the client need to pay attention to the server's responses? (b) Assume the server reads each client message with gets() or the equivalent, which reads in a string up to a . What would it have to do even to detect that a client had used command pipelining? (c) Pipelining is nonetheless known to break with some servers; find out how a client can negotiate its use.

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.
Can someone please help me with this? I'll give a thumb up to thank for your time.As I'm reviewing for my upcoming exam, I really need an answer from an expert in the field. Please do not send me an answer from chatGPT. I've got enough of that, so please be helpful.
With persistent communication, a receiver generally has its own local buffer where messages can be stored when the receiver is not executing. To create such a buffer, we may need to specify its size. Give an argument why this is preferable, as well as one against specification of the size.
