Ans:
TCP is a unicast connection-oriented protocol. Before either end can send data to the other, a connection must be established between them. TCP detects and repairs essentially all the data transfer problems that may be introduced by packet loss, duplication, or errors at the IP layer (or below).
TCP Connection Establishment and Termination:
Connection Establishment :
These three segments complete the connection establishment.
Connection Termination:
It is also possible for the connection to be in a half-open state, although this is not common. The half-close operation in TCP closes only a single direction of the data flow. Two half-close operations together close the entire connection.

In this lab, we’ll investigate the 802.11 wireless network protocol. Follow the instructions and answers questions 7 - 10. http://gaia.cs.umass.edu/wireshark-labs/wireshark-traces.zip In this lab, we'll investigate the 802.11 wireless network protocol. Before beginning this lab, you might want to re-read Section 6.3 in the text. Since we l1 be delving a bit deeper into 802.11 than is covered in the text, you might want to check out "A Technical Tutorial on the 802.11Protocol," by Pablo Brenner (Breezecom Communications) http://www.sss-mag.com/pdf802_11tut.pdf, and "Understanding...
Project 4-3: In the following steps, you will learn more about the PING (Packet Internet Grouper) utility, which can be used on a network running IPv4 to verify that TCP/IP is configured correctly and communicating with the network. A ping test is typically the first thing network professionals try when troubleshooting a TCP/IP connection problem. For this project, you can use any type of workstation that's running TCP/IPv4, preferably one connected to the Internet. The output described in the following...
Description: In this assignment, you will be launching a denial of service attack on a web server. We will be using hping3, a command-line oriented network security tool inside Kali Linux (an advanced penetration testing Linux distribution). Setting up the victim machine Download the Windows XP virtual machine with WebGoat server installed, using the following link. We will use this machine as the victim machine and launch a DoS attack on the WebGoat server.https://drive.google.com/open?id=0BwCbaZv8DevUejBPWlNHREFVc2s Open the victim machine and launch...
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...
