All the other steps for both are the application which it the physical app that you click on and it helps you use the app. Transport is the step that let you transfer data from point to point. The next step is Network which is responsible for addressing and controls the routing. The other step is what it does is that it is responsible for transition and establishes logical connections. The next is physical layer at it stream over physical media. The network components and there primary functions are that its build into layer and they all work with each other. There primary functions are that this that connects you to the network and it allows you to connect you to the network. The difference between WAN and LAN is that LAN primarily Ethernet and Token Ring and WAN uses technologies like MPLS, ATM, Frame Relay and X.25 for connectivity over longer distances. Basic security for data in networks is back up important files and making sure your computer is secure. Installing networks wireless it takes some configurations so it can work. Network tools help you connect and troubleshoot networking problems and it allows you to get through problems. The fundamentals of electrical circuits is that it allows you to connect to electrical elements such as resistors, inductors, capacitors, voltage sources, current sources and switches. Physical cabling is using cables like Ethernet, optic cables anything that deals with networking. Basic troubleshooting...

Wiring in these pictures don’t have any organization. As you can see if someone needed to replace a server or something it would be impossible. It would take a long time to trace each wire end to end. Also with this kind of unorganized wiring set up, wires may get hot and start a fire. There are no labels in place to state what wire goes to what. A system like this cause constant server down time do to wires being bent that may come a loose. This is an example of a rush job or someone who just didn’t care about what they left for someone. There are no surge protectors. There are no color coded wires. Even though no color coded wires are needed but it would have help since the wiring system is not tied nor labeled. This wiring system would take the system down until it get straightened out with down time valuable information could be lost or that could equal a valuable lost. If you came into repair the server room and wires were everywhere like this it would cost a lot of money to get the system fixed due to overtime for a down time server. It’s a maze of spaghetti or a bird’s nest of twisted and tangled wires. Overall this is a unorganized and un kept wiring set up. The above pictures are of a very neat and organized network. All wires are clamped together...

...Administrative Controls •How do Administrative Controls demonstrate "due care?" Administrative Controls demonstrate “due care” by providing and following policies, procedures, and standards that allow a company to show that steps were taken to protect the network and or information that is hidden by a responsible parties. It is critical that the CIA (Confidentiality, Integrity and Availability) is vital in protecting data that companies have of its customers. Due care is defined by the Information Systems Audit and Control Association (ISACA) as: 2.1.1 The standard of “due care” is the level of diligence which a prudent and competent person would exercise under a given set of circumstances. “Due professional care” applies to an individual who professes to exercise a special skill such as information system auditing. Due professional care requires the individual to exercise that skill to a level commonly possessed by practitioners of that specialty. 2.1.2 Due professional care applies to the exercise or professional judgment in the conduct of work performed. Due care implies that the professional approaches matters requiring professional judgment with proper diligence. Despite the exercise of due professional care and professional judgment, situations may nonetheless arise where an incorrect conclusion may be drawn from a diligent review of the available facts and circumstances. Therefore, the subsequent discovery of incorrect conclusions does not, in and...

...1. A network design customer has a goal of 99.80 percent uptime. How much downtime will be permitted in hours per week? How much downtime will be permitted in minutes per day and seconds per hour? Which values are acceptable in which circumstances? Ans: To compute the uptime/downtime is to take in concern merely the number of minutes before now passed for up-to-date month and existing year which is possibly what we need to find. A typical MTBF goal for a network that's extremely relied upon is 4000 hours. In different words, the network mustn't fail additional typically than once each 4000 hours or 166.67 days. A usual MTTR aim is one hour. In another sense the network failure ought to be fastened among one hour. I calculated downtime ratio by dividing occupied time into quantity of downtime. The summation of that number would be the ratio of downtime. Downtime for 99.8 percentile would be: Availability = MTBF / (MTBF + MTTR) SLA level of 99.8 % uptime/availability gives following periods of potential downtime/unavailability: * Daily: 2m 52.8s * Weekly: 20m 9.6s * Monthly: 1h 27m 39.5s 2.

Introduction “Harriet’s Fruit and Chocolate Company was established in 1935 in the Pacific Northwest of the United States to ship gift baskets of locally grown peaches and pears to customers in the United States (Oppenheimer, 2011)” In regards to the physical infrastructure of Harriet’s Fruit and Chocolate Company, my investigation will reveal many important aspects to aid in the planning of the network design. First, I will determine the number of buildings to be used, as well as the distance between them and what equipment they will contain such as wiring closets or computer rooms and the current network devices. Determining the distance will help in the cabling design and wiring as well as the selection of technologies and devices to meet the design goals. My investigation will further reveal any architectural or environmental constraints, such as tall trees within the path that power lines may travel, that will assist in decisions such as whether wireless technologies are feasible as well as if there are any impediments to communications or installation, to include all hazards. Infrastructure architecture consists of the hardware, software, and telecommunications equipment that, when...

For example threat like fire, hurricanes, tornadoes, flooding, lighting, earthquakes and electrical failure that can destroy the network vital information to be lost. In the case of any of these events, to protect the pharmacy from losing important patient data we need to secure this data by implementing a backup and recovery plan to help reduce the downtime to get back online and not loss customer loyalty. Offsite storage like Cloud technology can allow access to all critical information without invests additional resource to maintain the storage solutions and the staff to maintain integrity of the network. When looking at logical threats we must protect the network from unauthorized access internally and external attacks. Hackers understand that every device on the network has it weakness and they are trying to take advantage of it, devices that are most looked at are: servers, switches, routers, desktops, security devices and internal employees themselves. Unauthorized access of the database is a major concern when protecting the IT infrastructure...

...Impact of Data Classification Standards The three IT infrastructures that will be used is the Workstation Domain, LAN Domain, and the User Domain. The workstation domain is going to help with security because only approved employees or personal will be able to access the entire company’s network. While certain employees will only have access to information that they absolutely need to be productive. Keeping the workstation domain well managed will prevent a lot of security issues since we know who is or isn’t on the network. The LAN Domain is how we will manage all of our connected computers to each other that have access to all the same materials. Once again there will be certain employees that will have more access than others to certain parts of the domain and its physical and data components. This particular domain needs a strong security control because unauthorized access to this domain would be hazards to the company because so much valuable information is stored on it. The User Domain is a simple domain that will control who may or may not access the information on the systems. It is not the highest secured domain but holds all people who use it accountable for their use because they will have to know and understand the basic use policies set in place. Also only certain users will have different access to certain things so all users will be responsible for the information they save and process on their work stations or at the computers that they are...

...a great team that will work together in making it happen. When managing the security of a networked, one thing to keep in mind is to always try and stay one step ahead of the cyber criminals who want to steal, alter and destroy your data. You can’t stay in one place for very long, because hackers are always improving their methods and trying harder and using increasing creativity each day to breach your network and access all the assets it contains. Now we always have to keep in mind that in many cases the attacks aren’t even related to a network breach, since the most destructive attacks are carried out by insiders who are authorized to connect to your network. A first good step to improving your network security is to look at the physical side of it and improve it. If an attacker takes physical control of a computer in the network then they can use a number of tools to access information that is on the hard drive or moving to and from the computer . This is why physical security must be a primary concern before thinking of other security methods. Some of the physical security you can focus on is cards or biometric access controls to the rooms were computers are located. Also video surveillance of the entrances and exits of rooms where assets are located is very important. Logging...
