In these Wireshark labs we will observe the operation of real network protocols. You will be running various network applications in different scenarios using a computer in the lab or your own computer, if you prefer. You will observe the network protocols in your computer “in action,” interacting and exchanging messages with protocol entities executing elsewhere in the Internet. The basic tool for observing the messages exchanged between executing protocol entities is called a packet sniffer.

Digital forensics is the part of forensic science relating to proof found in computers and advanced storage media. Forensic examiners gather, protect and break down logical confirmations over the span of examination. Digital information contains data as content, pictures, sound, video and so on. These days numerous cybercrime cases, for example, hacking, banking cheats, phishing, email spamming, etc., have developed which are connected with a computerized information. Since the digital investigation is turning into an expanding concern, numerous digital forensic tools have been created to manage the difficulties of exploring computerized wrongdoings. The motivation behind digital forensics strategies is to look, protect and extract data on advanced frameworks to discover potential confirmations to exhibit them in the courtroom. In this paper, we have discussed five kinds of forensics namely Network Forensics, Live Forensics, Cyber Forensics, Database Forensics, and Mobile Forensics. The paper depicts a list of digital forensic tools in detail and looks at them based on the characterized parameters to figure out which tool suits better for any investigation. The paper looks at network, database and mobile forensic tools and examines the silent features and uniqueness of each of the tools along with their functionalities. __________________________________________________________________________________________ Keywords: Database forensics, Digital forensic tools, Forensic phases, Mobile forensics and Network forensics Introduction 5.

  • Network Monitoring and Detecting Packets Using Packet Sniffing Method
    International Journal of Scientific & Engineering Research, Volume 8, Issue 4, April-2017 ISSN 2229-5518 41 Network Monitoring And Detecting Packets Using Packet Sniffing Method S.Nagalakshmi ABSTRACT In the past five decades computer network have kept up growing in size, complexity, overall in the number of its users as well as being in a permanent evolution. Hence the amount of network traffic flowing at each node has increased drastically. With the development and popularization of network Technology, the management, maintenance and monitoring of network is important to keep the network smooth and improve economic efficiency. So to keep a track on these nodes a packet sniffer is used. Packet sniffers are useful for analyzing network traffic over wired or wireless networks. Sometimes a packet sniffer is called a network monitor or network analyzer. Many system administrator or network administrator use it for monitoring and troubleshooting network traffic. This paper focuses on the basics of packet sniffer; it’s working Principle which used for analysis Network traffic, how it works in both switched and non switched environment, its practical approach, its positive vs negative aspects and its safe guards. KEYWORDS: Packet Filter, Promiscuous mode, Spoofing and Intrusion, Network Monitoring, Network analyzer. —————————— —————————— I. INTRODUCTION with new switches. The replacement of hub with new Packet sniffing is the process of capturing the switches that makes switched environment is widely used information transmitted across network. In this process because it increases security. However, the thinking NIC capture all traffic that is flow inside or outside behind is somewhat flawed. It cannot be said that packet network.
