...it relates to network design considerations. It describes the rise of big data and the transition of traditional enterprise data models with the addition of crucial building blocks to handle the dramatic growth of data in the enterprise. According to IDC estimates, the size of the "digital universe" in 2011 will be 1.8 zettabytes (1.8 trillion gigabytes). With information growth exceeding Moore's Law, the average enterprise will need to manage 50 times more information by the year 2020 while increasing IT staff by only 1.5 percent. With this challenge in mind, the integration of big data models into existing enterprise infrastructures is a critical element when considering the addition of new big data building blocks while considering the efficiency, economics and privacy. This document also shows that the Cisco Nexus ® architectures are optimized to handle big data while providing integration into current enterprise infrastructures. In reviewing multiple data models, this document examines the effects of Apache Hadoop as a building block for big data and its effects on the network. Hadoop is an open source software platform for building reliable, scalable clusters in a scaled-out, "shared-nothing" design model for storing, processing, and analyzing enormous volumes of data at very high performance. The information presented in this document is based on the actual network traffic patterns of the Hadoop framework and can help in the design of a scalable network with the right...

In addition to that, hardcopy files of organization, worker, and customer information are saved in manager’s offices which are just protected by a wooden door (Apollo Group, 2004). Recommendations Because of a terrific lack in data protection features, the following suggestions are recommended: technique as well as risk evaluation, update on physical protection parts, and perform computer system and network protection. Strategy and risk assessment. All around data protection starts with the detection of dangers and the technique on the means to fix those dangers. This can easily be achieved by a Strengths, Weaknesses, Opportunities, and Threats (SWOT) assessment. Weaknesses and strengths are based on internal elements, for example workers, whereas possibilities and risks are based on...

...Basic Components of Network Management Systems Matthew D. Miller DeVry University A network management system is a system that is made up of hardware and software, whose job it is to manage the communications, software, and computer hardware of a network (Hill Associates, 2008). There are many different tools and components that help to make up a network management system. Some of these tools include trouble ticket systems, help desk systems, alarm correlation, maintenance tools, etc (Hill Associates, 2008). Along with all these tools there are four basic components that a network management system consists of. They are the agent, network management station, network management protocol, and the management information (Hill Associates, 2008). As mentioned before a network management system has many tools available to use. Trouble ticket systems are used to manage and keep track of any and all issues relating to the network (OTRS Team, 2012). A very useful feature of trouble ticket systems is that they save and archive the tickets with all pertinent information like who was involved, the problem and any notes or solutions (OTRS Team, 2012). In case a particular event occurs again the help desk team has a reference to look to for assistance. With any kind of machine or system, maintenance must take place in order for it to perform to its full potential. Software and hardware updates are essential for the smooth running of a network (TWD & Associates, Inc., 2012)...

...in a safe way, an organization might invest in an Enterprise Resource Planning system, or ERP for short. This system, although expensive, can monitor and control all aspects of data transfer within an organization. Using an ERP system can accurately report inventories, product details, work audits, and several other aspects of running a business (www.netsuite.com, 2001). Most important of all is accuracy. By Utilizing an ERP system the business will have several checkpoints where products and the processes for creating them are monitored. By always sending out the right product or information an organization can save a fortune in clean up costs and legal fees in the event of an error. An organization must also look at physical and network security options to protect all their assets, the integrity of the ERP system, and any other critical data flowing through or stored in the company. External Information Flow Mentioned before, external information flow can be represented as coming into or coming out of the company. This flow can be represented as supplies or finished product respectively. Each aspect has different challenges and requirements for effectively managing data and other resources.

...Network Design Following the acquisition of new premises comprising a two-story office in Adeplhi, Maryland this provides UMUC with the ability to revise and improve their network topology accordingly and ensure that not only is connectivity provided in a consistent fashion but also to provide the required security for information accordingly. One of the fundamental requirements is to ensure that data is segregated in terms of staff and students so this will require the creation of dedicated subnets accordingly to follow through and implement the solution, while there is also a requirement to provide wireless connectivity for students in the lobby area. Given that there is a specific opportunity to develop a comprehensive infrastructure it is important that the fundamental basis in terms of cabling is of a sufficiently high quality to support current and future operational requirements. Due to the size of the building there would be limitations if using Cat 5 based Ethernet cables for example and so therefore there should be a requirement to utilize Cat 6 based Ethernet as this will support a maximum cable length in excess of 300 ft without there being any connectivity or performance issues (Mitchell, 2014). Each of the two floors will have a designated server room that is designed to provide a central point of connectivity for all locations on that floor, and each of the rooms on the first and second floor will require a certain number of data ports based on their expected utilization...

The User Domain will enforce an acceptable use policy (AUP) to define which user can and cannot do with any company data that he or she has access to. Also, every user on the company is responsible for the safekeeping of the environment. 2. LAN Domain The Local Area Network Domain is a group of computers that are all connected to a single LAN domain. The LAN Domain is a collection of computers connected to each another or to a common medium. All LAN domains have data closets, physical elements of the LAN, and logical elements as designated by authorized personnel. It involves strong security and access controls. This domain can access company-wide systems, applications, and data from anyplace within the LAN. The LAN support group is in control of maintaining and securing the domain. The biggest threat to the LAN domain is an Un-authorized access to anything on the network. For example: LAN, the systems, and data. One thing we can do is require strict security protocols for this domain, such as disabling all external access ports for the workstation. This would cause a no access protocol. 3.

...Foundations of Network Security Fundamentals of Network Security 2 Firewall Fundamentals 43 VPN Fundamentals 79 Network Security Threats and Issues 111 CHAPTer Fundamentals of Network Security 1 C OMPUTER NETWORK SECURITY is very complex. New threats from inside and outside networks appear constantly. Just as constantly, the security community is always developing new products and procedures to defend against threats of the past and unknowns of the future. As companies merge, people lose their jobs, new equipment comes on line, and business tasks change, people do not always do what we expect. Network security configurations that worked well yesterday, might not work quite as well tomorrow. In an ever-changing business climate, whom should you trust? Has your trust been violated? How would you even know? Who is attempting to harm your network this time? Because of these complex issues, you need to understand the essentials of network security. This chapter will introduce you to the basic elements of network security. Once you have a firm grasp of these fundamentals, you will be well equipped to put effective security measures into practice on your organization’s network.
