Wireshark Essay

For the purpose of this assignment snort will be used as intrusion detections systems which is an open source IDS, snort has the ability to monitor traffics in real time and packet locking its also inspecting each packets as they enters into the network, Snort can be used as packet sniffer to analyse the network traffic in order to detect any bizarre looking packets or payloads which might have malicious data in it. Snort can also detect payloads attacks against the network or host system including but not limited to stealth port scan, and buffer overflows.

in four categories: intrinsic features e.g. duration of the connection, type of the protocol (tcp, udp, etc),

OpenAudit application will alert to what traffic is on the network, how the network is setup and identification of how changes are effected.

Wireshark is an open-source program which enables users to actively capture and interact with the network traffic which is being funnelled through the computer. Commonly, pieces of software which do this are referred to as ‘packet sniffers’ - As the program is recording the packets which pass through the network.

In my first screenshot, I have captured 4888 packets from my Local Area Connection. Within the first screenshot it shows the capture filters which includes TCP, IPX, UDP, etc. Furthermore, it’s just showing how to capture packets within a network. Wireshark is a sniffer that helps the user search within packets that allows it to be monitored to be analyzed with data. The purpose of this Hands-on Activity 4A, was to have the student experience and learn how to download and use a software (Wireshark) to increase their knowledge of advantages and disadvantages are within a sniffer. The steps I took were to browse the selection of the options provided on the program. I read some of the instructions in the textbook, Business Data Communications

Reflecting on several previous studies that have been carried out to compare the performance of the two NIDS, indicated Snort to be efficient in various issues. For instance, the comparison of Snort version 2.8.5.2 to Suricata version 1.0.2 was a clear indication of the strength of each system engine when subjected to the protection of the network. Their testbed incorporated the Ubuntu 10.04 which is a Virtual device accommodated on a VMWare Terminal 6.5 virtual setting operating on a 2.8GHz Quad-Core Intel Xeon CPU that had a 3GB RAM. The research was examining the quickness of detection and the accurateness of under changing rates of network and CPU usage (Albin, 2011). The control of the CPU used the Cpulimit with Tepreplay controlling the network bandwidth. The alert signals was accomplished by introducing six unknown malware that was created using the Metaspoilt framework. The results characterized Snort being efficient with system properties as compared to Suricata, but when functioning in a multi-CPU setting Suricata was extra efficient as a result of fewer false negatives

While both Wireshark and NetWitness Investigator can be used to capture network traffic, the freeware version of NetWitness Investigator has a limitation of 1G of protocol capture per session. Wireshark does not have a limitation on the size of the capture file, which makes it better suited to protocol capture. Wireshark can be used to analyze capture files, but NetWitness Investigator is a seven-layer protocol analyzer that provides detailed protocol analysis and protocol behavior analysis and is much more user-friendly in terms of understanding protocol behavior and protocol analysis.

Network protocol communications, network connections established by host computer, network routing information, information about computers

A good place to begin with any examination is with the statistical and metadata information that can be uncovered within the packet capture. Using Wireshark Protocol Hierarchy Statistics, we can see that the traffic consists mainly of DNS datagrams (figure 1).

For our purpose we will focus on ECHELON was collects and analyzes signals of various networks. ECHELON was created to monitor

There are two types of Internet Protocol (IP) traffic, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Some of the features that UDP possesses that are not provided by TCP/IP. First, UDP is a connectionless protocol (No handshake), which means packets sent from one node to another without making sure whether any packet may be lost during the transfer. TCP, on the other hand, makes sure to establish a connection in order to send the packets from one node to another without losing any packets. It is also known as handshake process, where nodes synchronize (SYN),

on the system. This makes it hard to identify, and consequently it is a hazardous kind of assault.

* Check existing security scan reports, from WireShark and NetWitness Investigator, and see if we can identify data leakage, and setup new policies and procedures for monitoring web servers and applications.

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

Network communication is an increasing phenomenon as associated technologies are improving. This is very important in the all aspects of life. In present time, there is a lot of traffic over various kind of networks. Due to this, the network performance gets compromised. There are wide range of network performance and traffic generation tools available and these are very useful for the network administrator. With the help of these tools, they can monitor and test network performance. However, it is not an easy task to find an appropriate tool and start checking performance related attributes. It is like looking for a needle in a haystack due to the large number of availability of these tools. It is very difficult to find tools that are suitable with desired characteristics and features.
