COMPARATIVE ANALYSIS OF PACKET SNIFFERS : A STUDY Jyoti Senior Engineer, Bharat Electronics Limited (India) ABSTRACT Today everything is being centralized through a common dedicated network to ease its use, make it more user friendly and increase its efficiency. The size of these centric networks is also increasing rapidly. So the management, maintenance and monitoring of these networks is important to keep network smooth and improve economic efficiency. Packet sniffing or packet analysis is the process of capturing data passed over the local network and looking for any information that may be useful. There is a wide variety of packet sniffers available in the market that can be exploited for this purpose. This paper focuses on the basics of packet sniffer, its working principle and a comparative study of various packet sniffers. Keywords: Packet Capture; Packet Sniffer; network monitoring; wireshark; NIC I INTRODUCTION A packet sniffer is a program that can see all of the information passing over the network it is connected to. As data steams back and forth on the network the program looks at it or „sniffs‟ each packet. A packet is a part of a message that has been broken up. Packet analysis can help us understand network characteristics, learn who is on network, determine who or what is utilizing available bandwidth, identify peak network usage times, identify possible attacks or malicious activity, and find unsecured and bloated applications[1]. II WORKING There are two modes in which a network interface of a machine work i.e Promiscuous and Non-promiscuous. Promiscuous mode in one in which the NIC of the machine can take over all packets and a frame it receives on network, namely this machine (involving its software) is sniffer.

Using the Ethereal and Tcpdump Protocol Analyzers
Using the Ethereal and tcpdump Protocol Analyzers Doug Toppin Nov 2003 toppin.com Ethereal - 1 What is Ethereal? “ Ethereal is a free network protocol analyzer for Unix and Windows. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, viewing summary and detail information for each packet. Ethereal has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session.” Ethereal - 2 Similar Tools ● tethereal - textual version of ethereal ● tcpdump - textual protocol analyzer These tools use the pcap (libpcap) packet capture library (which can be used to generate custom capture apps) Ethereal - 3 What does ethereal look like? ● gui composed of 4-fields: – Menu bar – List of captured packets – Top-level info on selected packet – Detail of selected packet – See following slide for example Ethereal - 4 captured packet list Illus-1 overhead gui of selected packet detail of selected packet Ethereal - 5 Illus-2 Capture initiator Ethereal - 6 uses for these tools ● find messages that have errors in them without modifying code (adding debug prints) ● monitor/analyze lan traffic for activity/load/latency measurement ● save captured packets for later analysis (“ evidence” attached to an bug report) ● frequently used for passive intrusion detection and monitoring ● just to see what your network is up to Ethereal - 7 Illus-3 capture with payload selected (http) Ethereal - 8 Illus-4 note http text Ethereal -

TIME-BASED APPROACH to INTRUSION DETECTION USING MULTIPLE SELF-ORGANIZING MAPS a Thesis Presented to the Faculty of the College
TIME-BASED APPROACH TO INTRUSION DETECTION USING MULTIPLE SELF-ORGANIZING MAPS A thesis presented to the faculty of the College of Engineering and Technology of Ohio University In partial fulfillment of the requirements for the degree Master of Science Ankush Sawant March 2005 This thesis entitled TIME-BASED APPROACH TO INTRUSION DETECTION USING MULTIPLE SELF-ORGANIZING MAPS by ANKUSH SAWANT has been approved for the School of Electrical Engineering and Computer Science and the Russ College of Engineering and Technology by Carl T. Bruggeman Assistant Professor of Computer Science Dennis Irwin Dean, Russ College of Engineering and Technology SAWANT, ANKUSH. M.S. March 2005. Electrical Engineering and Computer Science Time-based Approach to Intrusion Detection using Multiple Self-Organizing Maps (82pp.) Director of Thesis: Carl T. Bruggeman Anomaly-based intrusion detection systems identify intrusions by monitoring net- work traffic for abnormal behavior. Integrated Network-Based Ohio University Net- work Detective Service (INBOUNDS) is an anomaly-based intrusion detection system being developed at Ohio University. The Multiple Self-organizing map based Intru- sion Detection System (MSIDS) module for INBOUNDS analyzes the time-based be- havior of normal network connections for anomalies, using the Self-Organizing Map (SOM) algorithm. The MSIDS module builds profiles of normal network behavior by characterizing the network traffic with four parameters. A SOM, developed for each time interval, captures the characteristic network behavior for that time interval using the four parameters. This approach achieves better characterization of normal network behavior, leading to better intrusion detection capability. During real-time operation, the four-dimensional vectors, representing the attack connection for the time intervals, are fed into respective trained SOMs.

Automating the Generation of Cyber Range Virtual Scenarios with VSDL
Automating the Generation of Cyber Range Virtual Scenarios with VSDL Gabriele Costa, Enrico Russo, Alessandro Armando DIBRIS, Universita` degli Studi di Genova Genova, Italy [email protected] Abstract A cyber range is an environment used for training security experts and testing attack and defence tools and procedures. Usually, a cyber range simulates one or more critical infrastructures that attack- ing (red) and defending (blue) teams must compromise and protect, respectively. The infrastructure can be physically assembled, but much more convenient is to rely on the Infrastructure as a Service (IaaS) paradigm. Although some modern technologies support the IaaS, the design and deployment of scenarios of interest is mostly a manual operation. As a consequence, it is a common practice to have a cyber range hosting few (sometimes only one), consolidated scenarios. However, reusing the same scenario may significantly reduce the effectiveness of the training and testing sessions. In this paper we propose a framework for automating the definition and deployment of arbitrarily complex cyber range scenarios. The framework relies on the virtual scenario description language (VSDL), i.e., a domain-specific language for defining high-level features of the desired infrastructure while hiding low-level details. The semantics of VSDL is given in terms of constraints that must be satisfied by the virtual infrastructure. These constraints are then submitted to a SMT solver for checking the satisfiability of the specification. If satisfiable, the specification gives rise to a model that is automatically converted to a set of deployment scripts to be submitted to the IaaS provider. 1 Introduction Cyber defence (as well as offence) rely on security experts that must be properly trained and equipped with adequate security tools.

These tools have made it easier for an analyst to view the data instead of reading it, because it is easier for them to comprehend the information. The tools created can do more that just display the information they can allow the analyst to filter certain packets so that the visual representation isn’t overwhelming.
