Case Study In Computer Security
Paper , Order, or Assignment Requirements

This assignment comprises of four parts. All parts should be compiled into one Word document and submitted to the Submissions Area.
Part 1: Case Study 1: Textbook Chapter 2: “Security of Technical Systems in Organizations: An Introduction”
Many of the technical controls put into place can be circumvented with a simple phone call. Recently, famed hacker Kevin Mitnick demonstrated this, by breaking into Sprint’s backbone network. Rather than mounting a buffer overrun or denial-of-service (DoS) attack, Mitnick simply placed a call posing as a Nortel service engineer and persuaded the staff at Sprint to provide log-in names and passwords to the company’s switches, under the guise that he needed them to perform remote maintenance on the system. Once the password information had been obtained, Mitnick was able to dial in and manipulate Sprint’s networks at will.
Many people believe this was an isolated incident, and they would not fall for a similar act of social engineering, but Mitnick gained notoriety during the 1980s and 1990s, by performing similar techniques on computer networks around the world. Mitnick’s more notorious crimes included accessing computer systems at the Pentagon and the North American Defense Command (NORAD), and stealing software and source code from major computer manufacturers. Kevin Mitnick was arrested six times. He has been working as a consultant, specializing in social engineering techniques, having gone straight after serving a five-year sentence for his most recent crime. He has authored several books regarding social engineering, including The Art of Intrusion and The Art of Deception.
Create a 2- to 3-page report in a Microsoft Word document that includes responses to the following:
• Analyze what procedures could help prevent a similar breach of security at your organization.
• Phishing (the practice of luring unsuspected Internet users to fake Web sites by using authentic looking email) is usually associated with identity theft. Analyze whether this tactic could also be used to gain information needed to circumvent security controls. Why or why not?
• Many social engineering breaches involve using what is believed to be insider information to gain the trust of individuals in an effort to obtain confidential information. Test your ability to obtain what some might consider insider information using a search engine to find contacts or other useful information referencing your organization. Report your findings.
Part 2: Case Study 2: Textbook Chapter 5: “Network Security”
A recent network security breach at Tucson, Arizona–based CardSystem Solutions Inc. has exposed 40 million credit card customers to possible fraud, and is considered one of the largest card-information heists ever. CardSystem Solutions admitted that it improperly stored consumers’ data in its system. So possibly, the hackers apparently took advantage of network vulnerability in one or more of its systems. CardSystem is a third-party processing facility, which performs back office processing for MasterCard as well as several other banks and credit unions. Companies such as CardSystem perform payment processing, but need not store data for future use. Therefore, the incident calls into question the sloppy handling of customers’ personal information as well as lapses in security measures.
The thieves apparently installed scripts that allowed them to download the customer information. It is also unclear how long the information was being viewed or downloaded for fraudulent purposes. Proper auditing would have detected such an event in its earliest stages. But the security breach was apparently detected by MasterCard after they noticed fraudulent activity on their customer accounts. Some credit card companies have been mailing letters to the affected customers, but many do not automatically replace the cards unless a customer requests a replacement. It is uncertain whether or not the cost of lost customer goodwill will be associated with the mistake for CardSystem. But having your best customers inform you of a breach in trust of this magnitude could be devastating.
Companies such as CardSystem solutions are not explicitly covered under any federal regulation to ensure they are in compliance with security best practices. Therefore, this is going to fuel further debate for more stringent and wide-sweeping legislation. The Gramm-Leach-Bliley Act was designed to cover financial institutions and gives the Federal Trade Commission the power to enforce security guidelines, but third-party processing firms are not bound to any security guideline except by contractual agreement. However, in light of the recent security breaches, there are already calls to include any entity that’s dealing with sensitive financial information under the Gramm-Leach-Bliley Act to ensure compliance with security best practices.
• Describe a layered security approach that would prevent easy access to the information stored on CardSystem’s servers.
• Explain what measure could have allowed earlier detection of fraudulent activity, and aided in the investigation and why?
• Analyze what could have prevented a program being installed that allowed access to customer files.
• Describe the difficulty in adapting legislation to meet emerging business models in the information age.
Part 3: Ad-Ware and Forensics
Based on your learning of this week, respond to the following:
• Imagine that your computer has been infected with an Ad-Ware. You systematically follow steps to remove the Ad-Ware. You have used commercially available antispyware software, but to no avail. Discuss what may be wrong and what further steps you can possibly take to ensure complete eradication.
• Scan the popular press for computer crime cases. Gather information on the kinds of evidence that was collected, its usefulness in apprehending the culprit, and emergent problems and concerns, if any. Draw lessons and present best practices for computer forensics.
Part 4: Research Case Study
Using the Argosy University Online Library and the Internet, provide a significant case study that reports about one of the issues discussed during the course. Ensure that, if you wish to deviate from the topics discussed, the overall direction of the material still fits under the greater umbrella of computer security. The case study can be from a peer-reviewed journal or from a textbook. Try to find something close to your area of interest professionally. This will help you act as a computer security expert. After successfully providing a case study, create a report that includes:
• A short introduction to the case study.
• A set of five questions designed by you, highlighting the key points discussed in the case study.
• Answers to the questions you designed, explaining the key points of your interest for this particular case.

UMUC CMIT 265 Network Design Paper | Part 1 Part 2 Part 3
Paper , Order, or Assignment Requirements

I. Network Design

A. Network Topology

Technical Requirements

In this section, you will assess UMUC’s technical requirements. Use the information provided in the scenario to analyze the need for network topology, cables and connectors, networking and internetworking devices, wide area networking design, and computer systems. If you need more information, feel free to ask your instructor or make some assumptions. If you make assumptions, be sure to list them. This section should be used to describe the technical requirements of the task at hand. That is, you will be making explicit the requirements as you understand them, which will lead to the next section (your proposed solution).

Example (Note: The paragraph that follows is an example. It is expected that students will use this as a reference only. Remember to include references and cite your work according to IEEE-style format.)

Secure Network Contractors believes that students and faculty health, well¬being, and morale have a significant impact on the learning experience and productivity of the academic institution. Secure Network Contractors understands the following technical requirements. The university has invested in a new building that will bestow an academic ambience while providing students and faculty a world class research and learning environment. The university has hundreds of Faculty that teach and perform research within the new academic building. Faculty should be able to seamlessly transition between the newly leased building, and other buildings on the UMUC campus. Students will be required to have a similar experience as classes take place in multiple buildings across campus each day. Faculty and students will be required to print regardless of location, and therefore needs shared printing resources. All computers should be able to communicate, but the human resources department should operate on a separate network due to the sensitive and personally identifiable information they handle. We understand that the newly leased building will need to wirelessly communicate with other buildings on campus, and we will address this in the Wide Area Network (WAN) section that follows. Etc. (students should continue to explain the technical requirements).

Proposed Topology

Select one or more topologies to use for this design (i.e., star, bus, mesh, ring, and please note that the star topology is the most commonly used). This section should be used to provide the details of your proposed solution. Be specific and include the model, manufacturer, features, and cost of devices where appropriate. Students should include a visual representation of the topology selected. Topologies can be created using Microsoft Visio, or you can create a free account at draw.io (https://www.draw.io) and create diagrams. Be sure to review the types of topologies and highlight the benefits and drawbacks for each.

Example (Note: The paragraph that follows is an example. It is expected that students will use this as a reference only. Remember to include references and cite your work according to IEEE-style format.)

Secure Network Contractors believes that from a comparison of all the types available a ring topology is the best solution based on the requirements described by the University of Maryland University College (UMUC). We believe a ring topology satisfies the requirements of forming a single, continuous pathway for data to be transmitted through each node. A ring network topology in where each node connects to exactly two other nodes. A node on a network can be considered a computer, laptop, printer, or mobile device. Each node has a unique network address, which is referred to as the Media Access Control (MAC) address. The MAC address provides… Etc. (students should continue to explain their proposal).

Justification

This section should be used to justify your proposed solution based on the requirement(s). That is, you are explaining why you proposed the solution in the aforementioned paragraph, based on the technical requirement you made explicit in aforementioned paragraph.

Example (Note: The paragraph that follows is an example. It is expected that students will use this as a reference only. Remember to include references and cite your work according to IEEE-style format.)

Secure Network Contractors believes that a ring topology is the best solution based on the requirements described by the University of Maryland University College (UMUC). Specifically, the requirement that data flows in one direction, reducing the chance of packet collisions. The ring topology reduce the need for network servers because they are not needed to control network connectivity between each workstation. Etc. (students should continue to explain their proposal).

II. Network Addressing and Security

A. Subnetting

Overview

Subnetting is a process of breaking a large network into small networks known as subnets. Subnetting happens when we extend the default boundary of the subnet mask. Basically, we borrow host bits to create networks (i.e., subnets).

We have been assigned the network address 192.168.2.0. Based on the chart below, we know this is a Class C address. This is determined by observing the first octet of the IP address, which is 192. This octet falls in between 192 and 223.

Class
Octet Decimal Range
A
1 – 126
B
128 – 191
C
192 – 223

Each class has a predefined default subnet mask that tells us the octets, which are already part of the network portion, as well as how many bits we have available to work with.

Assignment: Budget Planning and Control
Paper , Order, or Assignment Requirements

Babycakes, a specialty bakery, is the company that will be considered for all parts of your budget planning and control report. For this assignment, you will develop a three to four (3 – 4) page paper in which you address the following.
1. Briefly discuss the ways a realistic budget will benefit the owner of Babycakes versus having no budget at all. Be sure to use Babycakes as the company and any specific product details in your explanation.
2. Prepare a sales budget for the LA Babycakes store for the 4th quarter of 2016. Present the number of units, sales price, and total sales for each month; include October, November, and December, and a total for the quarter. Use one-half of the Valentine’s Day sales as the basis for a usual day in the new quarter. Use 30 days for each month. Calculate the total sales for each month for October, November, and December.
3. Create three (3) new products, one (1) for each of the three (3) holiday seasons in the 4th quarter. Estimate the sales units, sales price, and total sales for each month. Describe the assumptions used to make these estimates. Include an overview of the budget in the report, presenting the actual budget as an appendix with all data and calculations. Add these amounts to your sales budget.
4. The owner of Babycakes is interested in preparing a flexible budget rather than the static budget she currently uses. She does not understand why, when sales increase, her static budget often shows an unfavorable variance. Explain how a flexible budget will overcome this problem. Use the details of your newly prepared budget for the 4th quarter of 2016 to address her concern.
5. Imagine that Babycakes is facing a financial challenge that is causing the actual amount of money that it spends to become significantly more than its budgeted amount. Include a discussion of your own unique cause of the overspending. Explain the corrective actions needed to address these challenges.
6. Integrate relevant information from at least three (3) quality academic resources in this assignment. Note: Please do not use your textbook as an academic resource. Also, Wikipedia and other Websites that are unreliable do not qualify as academic resources.
