a. Which packets perform the 3-way handshake? Identify them by packet number.
b. Identify the connection’s source and destination port numbers. Identify the application associated with this connection.
c. Identify a packet, by number, that “acks” data transmitted on this connection. What is the ACK number provided in that packet?
d. Identify the packet, by number, that sent some of the data “acked” by the packet in the previous question. What is the SEQ number provided in that packet? How many bytes of data were carried in that packet?

In frame 126, follow the TCP stream. What is the request that is
made to the server?
What response does the server give back?
Based on these messages and others you can see in the packet
capture, what would you say is going on? Is this an attack? If so,
what type of attack might it be?

TCP computer networks
Assume that a station X wants to send 15 packets of data to station Y using TCP Tahoe. Assuming that:1) The size of each packet sent is 1000 Bytes (ignore all the headers from layers below).2) Station X chooses 43 as an initial sequence number.3) Station Y chooses 2 as an initial sequence number.4) The data of the first packet is included in the final packet of the handshake process.5) The sender window size is 5 packets.6) The receiver window...

QUESTION 17 We assume that a LAN network includes 7 hosts (A, B, C, D, E. Fand G) which are connected by a switch. The contents of the switch's CAM table is as follows: (Port 1. Host A) - (Port 2. Host B) - (Port 3. Host - Port 4, Host D) - Port S. Hosta-Port 6, Host F) - (Port 7. HostG), Also, we assume that there is/are one or many host(s) that has/have sent fake...

Risk management in Information Security today Everyday information security professionals are bombarded with marketing messages around risk and threat management, fostering an environment in which objectives seem clear: manage risk, manage threat, stop attacks, identify attackers. These objectives aren't wrong, but they are fundamentally misleading.In this session we'll examine the state of the information security industry in order to understand how the current climate fails to address the true needs of the business. We'll use those lessons as a foundation...
