Solution: SysLocation in System group \\8 - Net-MGM-5.ppt 3) TCP is a connection-oriented protocol and UDP is a connectionless protocol. Indentify the differences in the two MIBs that exemplify this difference. Solution: TCP connection table has local and remote addresses as indices.

firewalls. These methods filter network traffic at one or more of the seven layers of the ISO network model‚ most commonly at the application‚ transport‚ and network‚ and data-link levels. In addition‚ researchers have developed some newer methods‚ such as protocol normalization and distributed firewalls‚ which have not yet been widely adopted. Firewalls involve more than the technology to implement them. Specifying a set of filtering rules‚ known as a policy‚ is typically complicated and error-prone. High-level

1. Which tool is better at performing protocol captures and which tool is better at performing protocol analysis? Net witness Investigator is best at performing protocol captures and Wireshark is better at performing protocol analysis. 2. What is promiscuous mode and how does this allow tcpdump‚ Wireshark‚ and Netwitness Investigator to perform protocol capture off a live network? “Promiscuous mode is a mode for a wired network interface controller (NIC) that causes the controller to pass all

Looking at the above graph‚ write a short paragraph on what is happening here with the congestion window and the flight size. Based on the graph I believe that the congestion on the server starts around 5‚000 bytes and continues to increase for the next 11 seconds of the transmission. The flight size starts

Lab 2.6.2: Using Wireshark™ to View Protocol Data Units Learning Objectives • Be able to explain the purpose of a protocol analyzer (Wireshark). • Be able to perform basic PDU capture using Wireshark. • Be able to perform basic PDU analysis on straightforward network data traffic. • Experiment with Wireshark features and options such as PDU capture and display filtering. Background Wireshark is a software protocol analyzer‚ or "packet sniffer" application

to block network traffic from the suspected source‚ which could be automatic or at the control of an operator. Therefore a reactive system will act in response to the threat were as a passive system will only log and send an alert to the console informing the operator of a threat. There are many types of intrusion detection systems‚ network intrusion detection‚ host based‚ protocol based‚ application protocol based‚ anomaly based and hybrid. The first one we are going to discus is network intrusion

LAB 12 Introduction In this lab you will use the Wireshark packet analyzer to capture and display the control information and data stored in packets transmitted over a network. Wireshark collects network traffic data and creates files that display packet header information in a layered format like that used by the Internet model. These layers can be expanded to view details that may prove helpful in determining the source of problems that your network might be experiencing. Creating filters that

and Answers 1. Which tool is better at performing protocol captures and which tool is better at performing protocol analysis? Wireshark is better for performing protocol analysis and Netwitness Investigator is best at performing protocol captures. Wireshark does well at both aspects‚ which makes it a little better. 2. What is promiscuous mode and how does this allow tcpdump‚ Wireshark‚ and NetWitness Investigator to perform protocol capture off a live network? Promiscuous mode is for
