- Computer Science Suppose KDC X serves one community of users and KDC Y serves a different community of users. KDC X and KDC Y have an established shared symmetric key KXY. Develop the steps of communication needed to enable customer A of KDC X community, to obtain a shared session key with customer B of KDC Y community. KDC X shares a symmetric key with A, KAX, and KDC Y shares a symmetric key with B, KBY. At the end of the steps of communication A and B will have established a session key, KAB.Question: Need help with finishing Python script. Using the pypcapfile library (already available in the VLE), along with the sample PCAP Files provided, develop a Python Script that extracts features of each packet. For each processed PCAP File generate a report with the following information for each unique connection observed and each Observed Port.Keep in mind that packet reordering and reassembly occurs throughout the TCP/IP protocol suite's functioning throughout the transport phase.A firewall can function at a lower abstraction level, such as the Internet or data layer, if necessary.A stateful inspection firewall that uses stateful inspection will lose any information about a traffic stream that is out of order or has been destroyed.
- Keep in mind that the TCP/IP protocol suite's transport phase involves reordering and reassembly of packets. Some firewalls are designed to function just at the Internet or data layer level of abstraction. An out-of-order or deleted traffic stream renders a stateful inspection firewall useless.Consider the network shown below. The IP and MAC addresses are shown for hosts A, B, C and D, as well as for the router's interfaces. Consider an IP datagram being sent from node B to node D. 77-34-F1 EF-14-72 128,119,97,18 A (1) 68-01-BC-58-AF-24 128,119,50,107 B 49-FA-B0-3C-E2-7C 128,119,50,60 72-9E-40-31-9C-42 128.119.240.15 CC-A5-81-08-AF-33 128,119.97.194 40-00-A0-74-06-1F 128,119,240,52 (5) C D5-AO-EE-9A-73-06 128.119.240.116 A. What is the source/destination network- or link-layer address at the location (3)? B. What is the source/destination network- or link-layer address at the location (4)? C. What is the source/destination network- or link-layer address at the location (5)? Consider an IP datagram being sent from node A to node C. D. What is the source/destination network- or link-layer address at the location (2)? E. What is the source/destination network- or link-layer address at the location (4)? F. What is the source/destination network- or link-layer address at the…Remember that packet reordering and reassembly occur throughout the TCP/IP protocol suite's transit phase. A firewall may function at an abstraction level lower than the Internet or data layer. A stateful inspection firewall will be unable to determine anything about an out-of-order or erased traffic stream.
- Access to media by multiple senders at the same time lead towards data collision, which particular protocol(s) and at what Layer(s) these are available to cater this issue? Does these protocols ensure 100% collision free delivery? If not then what other mechanism are available to resolve the issue? Elaborate with the help of diagrams, how different types of MAC Address (unicast, multicast and broadcast) works. Among the two popular LAN technologies, Ethernet and Wifi, which one has the higher data www rate and highest bit error rate (also explain why)?18 IKT204-G H21, ARP Frane 647: 00 bytes on wire (48e bits), 6e bytes captured (480 bits) on interface e Ethernet II, Src: Hewlettp_ddia3:00 (3ci88:2ai dd:alree), Dst: Broadcast (ffiffiffiffiffiff) v Destination: Broadcast (ff:ff:ff:ff:ff:ff) Address: Broadcast (ff:ffiff:ff:ff:ff) ......1. .............

The SSLv2 protocol is known to have vulnerabilities. A man-in-the-middle attacker may push communication to a less secure level before attempting to decrypt the data. Encrypted communications may potentially be truncated by the attacker. SSLv3 has addressed these vulnerabilities (TLSv1). SSLv2 and SSLv3 are supported by the majority of servers and clients. For backward compatibility, SSLv2 is enabled by default. Please respond to the following questions. a) Determine the effect of the above statement. c) What is the answer to this problem? c) Do you believe SSLv3 is more secure than SSLv2? Justify your response.

Some firewalls are designed to function just at the Internet or data layer level of abstraction. Without the proper sequence or the absence of a deleted packet, a stateful inspection firewall cannot make any inferences about the traffic being inspected.19.
