SEC 280 Case Study Week 1 Ping Sweeps and Port Scans

Your boss has just heard about some nefarious computer activities called ping sweeps and port scans. He wants to know more about them and what their impact might be on the company. Write a brief description of what they are, and include your assessment of whether the activities are something to worry about or not. This assignment requires two to three pages, based upon the APA style of writing. Preview: One main security threat is the reconnaissance attack, which includes the two main types of threat that can affect a company’s network — ping sweeps and port scans. These are the unauthorized discovery of systems, which can lead to… SEC 280 Case Study Week 2 Information Security Officer

You are the Information Security Officer at a medium-sized company (1,500 employees). The CIO asks you to explain why you believe it is important to secure the Windows and Unix/Linux servers from known shortcomings and vulnerabilities. Explain to your CIO what you can do to make sure the network infrastructure is more secure. Preview: The company has a network of Windows and Linux servers, business products, and network management tools. Employees use mobile devices with business applications installed for higher productivity. In this regard, the IT network has to function at its optimum best so that the business functions smoothly. However, network security risk is a… SEC 280 Case Study Week 3 ABC Institute

ABC Institute of Research has sensitive information that needs to be protected from its rivals. The Institute has collaborated with XYZ Inc. to research genetics. The information must be kept top secret at any cost. At ABC Institute, the researchers are unsure about the type of key (asymmetric or symmetric) to use. Please formulate a possible solution, and describe the advantages and disadvantages of any solution employed. This assignment requires two to three pages in length, based upon the APA style of writing. Preview: There is much information available in the digital form. Some of it is personal; some public; and some are confidential and sensitive in nature. It is important to protect such information so that its confidentiality, integrity, and availability are not compromised upon. It has to be protected throughout the lifecycle of information creation, modification, storage, and disposal. If it falls into the wrong hands, it can be… SEC 280 Case Study Week 4 Computer Security

Case Study Computer security is not an issue for organizations alone. Anyone whose personal computer is connected to a network or the Internet faces a potential risk of attack. Identify all the potential security threats on a personal computer. Identify some of the techniques an attacker might employ to access information on the system. This assignment requires two to three pages in length, based upon the APA style of writing. Use transition words; a thesis statement; an introduction, body, and conclusion; and a reference page with at least two references. Use double-spaced, Arial font, size 12. Preview: Nearly18 million people in the United States were victims of identity theft, which mainly targeted people’s credit cards and bank accounts (Williams, 2015). There are a lot of malicious attacks on personal computers. These attacks can make the computer unusable and also compromise the user’s confidential information, as well as that of the network they are connected to. Hackers constantly… SEC 280 Case Study Week 5 An Information Security Engineer

Case Study You have just been hired as an Information Security Engineer for a large, multi-international corporation. Unfortunately, your company has suffered multiple security breaches that have threatened customers’ trust in the fact that their confidential data and financial assets are private and secured. Credit-card information was compromised by an attack that infiltrated the network through a vulnerable wireless connection within the organization. The other breach was an inside job where personal data was stolen because of weak access-control policies within the organization that allowed an unauthorized individual access to valuable data. Your job is to develop a risk-management policy that addresses the two security breaches and how to mitigate these risks. This assignment requires two to three pages in length, based upon the APA style of writing. Use transition words; a thesis statement; an introduction, body, and conclusion; and a reference page with at least two references. Use double-spaced, Arial font, size 12. Preview: Risk is the negative effect of an event or action or the probability of the event or action and its impact. On the other hand, risk management is the process of identifying and calculating the effect of the negative impacts, taking steps to avoid or mitigate risks, and accepting and managing risks that cannot be avoided or mitigated. The organization should have a… SEC 280 Case Study Week 6 Gem Infosys

Case Study Gem Infosys, a small software company, has decided to better secure its computer systems after a malware attack shut down its network operations for 2 full days. The organization uses a firewall, three file servers, two Web servers, one Windows 2008 Active Directory server for user access and authentication, ten PCs, and a broadband connection to the Internet. The management at Gem needs you to formulate an incident-response policy to reduce network down time if future incidents occur. Develop an incident-response policy that covers the development of an incident-response team, disaster-recovery processes, and business-continuity planning. This assignment requires two to three pages in length, based upon the APA style of writing. Preview: In the technology industry, a company is never 100% secure against unauthorized access, virus attacks, malware attacks, hacking, disasters, and theft of software and hardware. It is therefore important to have an action plan ready to manage incidents that attack the system. An action plan to manage the… SEC 280 Quiz Week 1-6
