IT IS important to have logical and physical network design diagrams. These diagrams help us in understanding of the entire network with its functionalities. Physical layout diagrams of the network shows connections between network devices and their physical location on the network. Workstations are represented by use of small computer icons, severs are shown with full tower cases. Switches and other network devices can be shown by use small rectangular boxes with their RJ-45 points. Sometimes switches are not displayed with their ports depending with their angle of view on the page. It is advisable to give more details as possible without overcrowding the diagrams. Logical aspects of the network are shown by the logical layout diagrams. Logical network may include assigned IP addresses to various hosts and devices, routing table might also be shown. When designing logical devices we are not interested with any physical cable or actual interface so we omit such kind of details. Physical and logical layouts are important because they help in security issues, management and for troubleshooting reasons. In case a problem arises such as link been down we use the physical layout and we are able to locate where problem is located. This helps a lot because it avoids waste of time. Logical and physical view of the network helps administrators and engineer to identify possible security issues. Hackers try to obtain access to highly sensitive data by first creating map of the network
Also print out the network diagram on two to three pages so that task information can be read.
The network diagram of Global Finance, Inc. (GFI) depicts the layout of the company’s mission critical systems. The company has two servers (Email and the Oracle database) which are used more than any of their other systems. GFI heavily depend on their network to be stable because of their financial systems that are running and any outage would negatively affect their operations and financial situation. Like all other business, customer satisfaction and the security of GFI’s network is crucial. In order to ensure their network and data is secure,
This assignment will be mainly about network components and how do they operate, what are their functions and what are their flaws.
What is the difference between a logical network diagram and a physical network diagram? (1 point) When would you use each type? (1 point)
* Networking comportments of IT infrastructure (XML interface; Electronic interface; IBM AS 400 Platform; Windows 2000 Platform; Local area networks).
It is a graphic organizer. It helps gather and organize large amounts of unsystematic data and information related to a problem into groups based on their natural relationships in order to determine possible solutions logically.
I am hired as an Information Security Engineer for a videogame development company. The organization network structure is given in the diagram. I was notified that malicious activities are taking place in the network structure. They can effect protection of the intellectual property and highly sensitive data maintained by the organization. I am assigned to resolve these issues that arise in the network structure. In this document I will analyze and assess potential malicious attacks and threats that may be carried out against the network along with potential vulnerabilities that may exist in the documented network. Also I will tell the potential impact of all malicious attacks & threats and identified vulnerabilities to the network and
First, we need to understand the difference between logical and physical topographical layouts. Logical layouts are how the data move across the network and physical layouts are how the network relates to its wires and hardware (Kevin Wallace, 2012). Note that how the data moves through the network is not going to be the same as how the data is physically structured (Michael Harris, 2008). The most coming physical topologies are Bus, Star, and Star-Wire Ring (Kevin Wallace, 2012). The most coming logical topologies are Bus, Ring, and Star (Kevin Wallace, 2012).
According to Kizza (2013), the rapid growth of networking has led to increased security risks. Many of these risks are as result of hacking, improper uses of network resources and network device vulnerabilities. Awareness of the various weaknesses and vulnerabilities is vital to the success of current networks (Kizza, 2013).
I chose this particular topic not because it’s easy, but because it will enhance the skills I already have. The topic selection should really not matter that much, since the topic will merely gauge to see what I will learn, and also challenge my ability to find solutions to various problems that I will encounter throughout this course. This will begin with week one and ending with week seven, provided with a business network scenario I will have to decide based on assumptions and requirements to either upgrade or design a network from scratch. My reasoning for this is simple, that if I apply what I am suppose to learn in this course, I should be able to quickly apply the process of top-down network design, keeping in mind the customers business goals and requirements, I will be successful in providing a justified solution or network implementation for any given customer and any given business scenario. That is the main goal of any structured systems analysis; it is to more accurately represent customer’s needs. (Oppenheimer 5)
Physical media is what physically connects the computers connected on the internet. For this network two physical media will be used to allow access to the application layers of the system. The coaxial cables will be used to create a WAN. While a wireless protocol will be used in allowing users to roam within the network. A LAN will be represented as follows;
Network architecture is the configuration of an interchanges system. It is a structure for the determination of a system's physical parts and their practical association and setup, its operational standards and systems, and information organizations utilized as a part of its operation. Network Architecture gives the subtle element outline of a system. It is utilized to arrange all the system layers regulated in sensible structure by portraying each one stage in subtle element. It is likewise dependent upon the complete working meanings of the conventions. The structural engineering is emphasized in a circulated processing environment and its unpredictability can’t be comprehended without a structure. Subsequently there is a need to create provisions or systems to design a diagram of a system. The first use of the expression "software architecture planning" put it particularly in the arranging period of a task. While these arrangements had connection to physical items, the term finished not. At the point when a system of associated gadgets, for example, phones and PCs, was arranged out, the outcome was a system building design schematic. The real plans were for the most part extremely fundamental; they might be all the more a rule than else other possibilities. In time, the system construction modeling schematic started to hold extra material identifying with the system. Particular physical articles were allocated positions dependent upon the
A network diagram is a graphical representation of any network, it’s a small structure of computers and network devices (routers, modem, Ethernet etc.) It is a sequence of steps. This network diagram represents setting up a Web Server with DMZ in an existing network.
