When composing a disaster plan the most important step is to perform a very comprehensive investigation of all risks in the network. This includes all computer systems, servers, networks, and etc. When investing the network there are many risks to consider. These risks can include attacks from viruses, deletion of data from company employees, floods or other natural disasters and etc. When listing these threats it should be taken in effect which risks have more impact on the company. Once risks are determined and put in categories of importance, XYZ Computers should consider some very common questions.
• How would the following affect XYZ Computers? o Virus attacks o Loss of personal information (company’s or employees) o Power outages o Loss of Internet service o Loss of phone service o Natural Disasters (floods, hurricanes, earthquakes, tornados, fires, and etc.)
• What would be company costs in the event of any of these disasters?
• What can XYZ Computers do to lessen the effect of disasters on our company?
• What can XYZ Computers do to prevent certain disasters from happening? Some companies in areas that power outages are common may have emergency power in place. They will also back up all of their data on RAID tapes frequently. While prevention can cost the company money, recovery from disasters that could have been prevented could cost much more. Some businesses have even had to close due to certain disasters that could have been prevented. “The Boy Scout motto of Be Prepared applies to almost everything in life” (Brister, 2010). XYZ Computers must know what data is the most important for the company as a whole. The data and applications must be able to be recovered quickly. The longer a business is down the more money it costs. This is why it is so important to test the disaster plan right after you have the plan and periodically. A company can never be too prepared. XYZ Computers’ Information Systems Technology (IST) Department is located on the first floor of the building. This part of the United States is very prone to heavy rain and flooding. Flooding has recently occurred in this building causing the servers to become damaged. No firewall is currently in place. This gives easy access to malicious activity. Not only does the company’s information need to be protected; the Company’s 10,000 employee records also need to be protected. The payroll is on the same server as the email. Not having a firewall to protect this information could prove to be disastrous if not corrected. This is why it is pertinent to develop a disaster plan. The first step to this plan would be to get the servers off the floor. The first consideration would be to move the IST Department to another floor. For some companies this may be impossible therefore a server rack could be an excellent choice for XYZ Computers. XYZ Computers should install a switch box to connect a single keyboard, mouse and monitor to several of their servers. This would cut costs on equipment and help organize the work area. This will also help with preventing damage to servers from flooding. The next step is to have a packet filtering firewall set up for the network. This would allow for a more secure internal network. I believe creating a demilitarized zone (DMZ) would be beneficial to XYZ Computers. “A DMZ consists of three ports on the firewall; the public networks on one port, the private network on another port and the DMZ one the third port. The DMZ is a less secure area than the private network. DMZ includes web and File Transfer Protocol (FTP) servers”. (Regan, 2006, p. 567). Once the firewall is set up the IST department will need to examine all firewall logs frequently for any suspicious activity. Using a Redundant Array of Inexpensive Disks (RAID) system is the final step in protecting the data and applications from being lost and allowing any data or applications to be recovered from failed disk drives. For exceptional results one must understand how the RAID system operates. “RAID is a category of disk drive that employs two or more drives in combination into a logical unit for fault tolerance and performance. RAID disk drives are used on servers.” (Regan, 2006, p. 598). The RAID system can also be made useful on workstations. This will allow for increased storage functions and reliability through redundancy. RAID schemes divide and duplicates between several disk drives. Each scheme sustains a different balance between two goals; increase data reliability and input/output performance. Some of the schemes continue operating even when part of the system fails.
There are six levels on the RAID system. They are as follows according to Regan (2006)
• RAID 0 – Disk striping – Data striping is the spreading out of locks of each file across multiple disks. It offers no fault tolerance, but it increases performance. Level 0 is the fastest and most efficient form of RAID and is supported by Windows Servers, Linux, and NetWare without additional hardware and software.
• RAID 1 – Disk mirroring/duplexing – Disk mirroring duplicates a partition onto two hard drives. When information is written, it is written to both hard drives simultaneously. It increases performance and provides fault tolerance. Disk duplexing is a form of disk mirroring. Disk mirroring uses two hard drives connected to the same card; disk duplexing uses two controller card, two cables, and two hard drives. Level 1 is also supported by Windows Servers, Linux, and NetWare without additional hardware and software.
• RAID 2 – Disk striping with Error Correction Codes (ECC) - Level 2 uses data striping plus ECC to detect errors. It is rarely used today since ECC is embedded in almost all modern disk drives.
• RAID 3 – ECC stored as parity – Level 3 dedicates one disk to error correction data. It provides good performance and some level of fault tolerance.
• RAID 4 – Disk striping with large blocks – Level 4 offers no advantages over RAID 5 and does not support multiple simultaneously written operations.
• RAID 5 – Disk striping with parity – RAID 5 uses disk striping and includes byte correction on one of the disks. If one disk goes ad, the system will continue to function. After the faulty disk is replaced, the information on the replaced disk can be rebuilt. This system requires at least three drives. It offers excellent performance and good fault tolerance. This also is supported by Windows Servers, Linux, and NetWare without additional hardware and software. Any of the above mentioned levels could be applied to XYZ Computers’ servers. What level used is very dependent on the financial standing of the company and the demand. It is very important that a RAID service be put into action as soon as possible. As I have looked over the demand for this company RAID 0 – Disk stripping along with RAID 1 – Disk mirroring/Disk duplexing should be utilized. RAID 0 is very fast and very efficient. It increase performance but has no fault tolerance. This is the reason RAID 1 should also be used. RAID 1 allows for every hard drive on the system to have an exact clone of data as the first drives. This scheme will continue operating even when one of the drives fails, by allowing the mirror drive to take over. The faulty drive will then be diagnosed and fixed. With RAID 1, disk duplexing is included. With disk duplexing the two drives are on different controller card. This allows for the drive, controller card, and cable to be redundant. (See figure 1)

Figure 1 RAID 1 + 0

In order to receive full protection from any disaster that may occur, this RAID system can be in place at two separate locations. One location could be in place in the same location as XYZ Computers and the other one can be in place at another geographical location. This will allow for double the protection of all data if any natural disasters occur in the future.

...Disaster Plan Nunki J Rosas IT/240 Sunday, April 7th, 2013. John Helt, MISM, MCSE Disaster Plan Scenario: The IST Department of XYZ Computers is located on the first floor. Payroll and all human resources records are processed daily and bi-weekly for 10,000 employees. After payroll is run, data is backed up using tapes. No firewall is in place, and e-mail is on the same server as payroll. XYZ Computers is located in the southern part of the United States in an area that receives heavy rain. During the weekend, a major water pipe broke and flooded the first floor. The water caused extensive damage to the servers, which were also on the first floor. Create a disaster plan to prevent this sort of problem from happening in the future. Proposed solution: The way in which XYZ Computers has their IST Department set up currently is susceptible to many threats. The lack of a firewall is an open invitation for data to be stolen by prying eyes, and the vulnerability of placing the payroll database is in the same server as the email service. The geographic and weather conditions of the location of the company have a high risk of flooding, yet the Servers were installed on the first floor. Lastly, the backup method in place is sort of outdated and there is no mention on how often the backup takes place; additionally, the backup tapes themselves could be damaged, lost, or stolen.

...Abstract: In the situation of XYZ computers flooding, this paper is to help create a disaster plan using different raid setups that might better help this company in the long run to back up there systems. I have gone into detail what is needed for the different raid systems and what they are good for below.   The first step in making sure that you have a stable system is to make sure that you have a proper back up plan, especially when you are dealing with the amount of employees that XYZ Computers has to deal with on a day to day basis. When starting out a disaster plan, we need to take in every possible situation that could arise, from natural disasters to think such as hacker exploits and even burglar exploits. We should even cover things in our disaster plan such as hardware failures, spyware, or even virus. We also need to list them all out, and take a look at what ones we are most likely going to have to deal with, and put most of our concentration on those, and then slowly work our way down the list making sure that we hit every single possibility that could arise. Another factor that should be looked into also while making a disaster plan would be the cost that we are willing to put out to put together a strong disaster plan. We want to be able to have something that is going to work without flaws, but also not have to break the bank while doing it. We also might want to think of ways that we can help prevent most of the disasters. In example, we really can’t anticipate...

Disaster Plan

...| Disaster plan | | | | 6/6/2010 | | Abstract This is a disaster plan that I created for the IST Department of XYZ Computers company in order to prevent any future problems that may arise such as the situation they had over the weekend when a major water pipe broke and flooded the first floor, causing extensive damage to the servers. Included in the disaster plan I will address a few issues that will aid the company in protecting against such things as any natural disasters that may occur as well as any other occurrences that may deem necessary for such a disaster plan. I will detail my recommendations for using a RAID system for data protection in order to have a well placed back up plan with the most up to date information possible. In short I plan to properly detail a disaster plan the best possible way that I can in order to have a good disaster recovery plan in place rather than having to spend the time and money on extra recovery efforts. Hopefully having such a plan in place will keep from losing important data to unforeseen issues, such as natural disasters due to the geographical location among other issues that may arise at the most in opportune time possible. When creating a disaster plan the first thing to keep in mind is to do a complete risk assessment of the entire existing computer systems. In order to accomplish this task all the risks and probabilities will need to be noted such as any delays to system uptime and how close at hand these...

...Disaster Plan Assignment week 8 The IST Department of XYZ Computers is located on the first floor. Payroll and all human resources records are processed daily and bi-weekly for 10,000 employees. After payroll is run, data is backed up using tapes. No firewall is in place and email is on the same server as payroll. XYZ Computers is located in the southern part of the United States in an area that receives heavy rain. During the weekend, a major water pipe broke and flooded the first floor. The water caused extensive damage to the servers, which were on the floor. IST unit of XYZ Computers is situated on first floor. The first order of business would be to relocate the servers to a more secure location on maybe an upper floor to avoid this type of event from occurring again. The company’s location means that we should consider moving all essential hardware for operations to second or third floor offices. The servers should not be on the floor no matter what floor they are located on. Heavy rains could also mean mud slides and extensive flooding. Having a warm site in a different region of the U.S. would make relocating the business easier if any natural disaster took place. Of course we would have to store remote servedrs that are being backed up at the same time that the servers on location are backed up in order to keep current on operations. The disaster scheme of the organization can be established on the RAID scheme of information protection. In order for this to occur...

Although the differences between Company A and Company B are more than slight in the approach they choose for the operation of their network, the concept of network security means the same thing. Zooming in on Company A, there is information of approx. 10,000 employees that travels through an unprotected portal that shares the company email server. This is about as serious of a threat as there is. Laid out within this written document are enactments much, much recommended. These implementations work together much like the individual pieces of a knight’s armor overlap each other a bit, meanwhile the sword and shield are actively about in front of; ready for an attack on their network. The following paragraphs are outlined in the order of the OSI model. Protecting all of the important assets of XYZ Computers means keeping them in a safe place, whether in storage or in full operation. According to Appendix G, there was a flood on the first floor that caused damage to all of the equipment. To protect the equipment from flooding, which is a seemingly big problem in the south, the equipment should be elevated from the immediate floor by means of some type of moat around the equipment or moved up to the second floor. The drainage system should also be further inspected to ensure there are not other pipe-bursting dangers. Also...

Application of Management Science in Business

...2014 Management Science Management Science is concerned with developing and applying models and concepts that help to clarify management issues and solve managerial problems. The models used can often be represented mathematically, but sometimes computer-based, visual or verbal representations are used. The range of problems and issues to which management science has contributed insights and solutions is vast. It includes scheduling airlines, both planes and crew, deciding the appropriate place to site new facilities such as a warehouse or factory, managing the flow of water from reservoirs, identifying possible future development paths for parts of the telecommunications industry, establishing the information needs and appropriate systems to supply them within the health service, and identifying and understanding the strategies adopted by companies for their information systems. Scientific Planning Successful management relies on careful coordination, often using scientific methods in project planning. For example, critical path analysis allows us to identify which tasks in a project will take the longest or adversely affect the length of other tasks, permitting us to focus on those tasks. Computer models can also help we determine utilization and recommend more effective usage. In addition, this type analysis allows us to develop proactive strategies for handling outages and...
