Nt1310 Unit 3 Networking Tools

In the Network Design Paper I will explain how the University has recently leased a building in Adelphi, Maryland. The measurements of the University is 240 feet long, 95 feet wide and 30 feet tall and broken down to two different floors. This University will be used for education purposes of course, the facility will be made of six instructional labs, seven offices, library, five classrooms, a student lobby and a computer lab. There will be a server room on each floor. The purpose of this paper is to explain the design of the networks in this building. The student accessed computers will be set up on a separate network than the network that they staff will be using.

* 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.

Answer: Telnet can be used to connect a UNIX , Linux, or Windows PC to a remote computer.

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.

First, let’s talk about Wireshark, it is the most common network packet analyzer used worldwide, perhaps one of the best open source (free) packet analyzers today. It lets you capture and interactively browse the traffic running on a computer network, helping you analyze and manage the traffic in your network. Like a measuring device used to examine what is going on in your network cable, like a voltmeter used by an electrician to examine what is going on inside an electric cable. Therefore, gives you the tools to do in depth network analysis, it will try to capture network packets and display them as detailed as possible for analysis. Furthermore, used for troubleshooting network problems, examine security problems, debug protocol

I accomplished in this lab how to access and changed the user name password and how to access the command (cmd) screen. I familiarized myself with the command screen and using the ping option. I found it difficult to locate the network monitor but after getting denied access I found out how to log on as Admin and view the network and changed the foreground colors. I must have made an error in the process because the ICMP would not change to red and I ran out of time. This was a great lab and I just wish I had a little more time.

Rob Pettigrew is the manager of technical systems and help desk center of Wyoming Medical Center in Casper, Wyoming. Protecting networks are getting harder as there are different types of devices being used by companies. An example of this is Wyoming Medical Center has four different classifications of PCs, PCs in the hallways for the staff to use, PCs at the nursing stations, PCs in offices, and PCs on that move between patient rooms. Pettigrew deployed Novell ZenWorks to 850 of the medical centers 900 PCs to ensure each one has the right software. With having multiple applications, medical software systems, and the different machine types, and restrictions make it difficult for Pettigrew to ensure proper protection for the network. Another concern is the

Network Security - Networks are classified into many types like shared and non-shared, public or private, small area or large area networks and each of them have a number of security threats to deal with. Problems associated with the network level security comprise of DNS attacks, Sniffer attacks, issue of reused IP address, etc. A Domain Name Server (DNS) server performs the translation of a domain name to an IP address. Since the domain names are much easier to remember. Hence, the DNS servers are needed. But there are cases when having called the server by name, the user has been routed to some other evil cloud instead of the one he asked for and hence using IP address is not always feasible. Although using DNS security measures like:

Remote desktop allows a user to enter in another computer on the user’s network. It allows to access data and applications, using the Remote Desktop Protocol

This configuration is the most flexible of those described, since it allows to connect the unit to the Internet and automatically download its historian data to a remote server. No particular configuration is required in this case since the only requirement is that the remote unit is configured with the fixed IP of the central server and can freely connect to the internet. This can be obtained, if the unit cannot be configured inside the plant network, by using a wireless 3G/4G adaptor which directly allows a connection to internet. The remote replication of data requires to implement a central data server to receive the data. This server should be installed either in Sea Marconi Head quarter or can be part of the client network. The cost of

A: Depends on your needs, max setup time is 7 working days and average 5 days. Please be patient!

I have also found out that sniffer can be used to track certain packets that were being sent and received when browsing on the Internet. For example, just searching up www.google.com packets are being linked to others when launched. The packets can be sent to ads, weblinks, or that specific site. This also provided me some personal knowledge about how people can track you based on IP when you ping to another destination. I found the hands-on activity very eye opening to the user using the program. It shows a lot behind the scene of what happens when you search for a simple website link nvcc.edu or google.com. I also found that people who work with networking could also benefit off of using a sniffer. They can determine how the traffic between the connection to another website/user. For instance, if multiple people demanded to search for one certain link and it ends up crashing the site. A network analyzer can see how many packets were received and requested within that period. The network analyzers could determine a solution based on the data provided from the program and help slower the traffic to prevent future crashes or failure to connect within the

It transmits mouse and keyboard actions from one computer to another to allow technical support personnel to operate server, desktop or other device via network as it is more efficient than to guide users through the whole procedure over the phone or to have the technical support personnel to be physically at the workstation.

One initial feature we looked at was how to access the server. Both Windows and Linux offer File Transfer Protocol (FTP), which would give us access to the files easily, but then Linux offers telecommunications network or telnet, which would allow us to remotely access the servers from another location, such as if were not at the office. It also offers Secure Shell (Ssh) that is a program for logging into a remote machine or the servers to execute commands. Now, Windows can be configured for telnet, but not Secure Shell.

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).
