Please be sure to follow APA v6 guidelines for the entire paper.Assignment 7. Go online and search for information about security threats posed by browser add-ins, such as Java applets and ActiveX controls (Do not use either of these examples). Note that most of these programs are small in size and downloaded onto computers over the Internet. Look for a specific example of a security problem resulting from such add-ins, and document the problem in a case study.

Quiz 4 Advanced Algorithm Analysis Marks 20Q 1. (10 points) Team work. You’re managing a consulting team of expert computer hackers, and each week you have to choose a job for them to undertake. Now, as you can well imagine, the set of possible jobs is divided into those that are low-stress (e.g., setting up a website) and those that are high-stress (e.g., approaching deliverable deadlines for a major client). The basic question, each week, is whether to take on a low-stress job or a high-stress job.If you select a low-stress job for your team in week i, then you get a revenue of li > 0 dollars; if you select a high-stress job you get a revenue of hi > 0 dollars. The catch, however, is that in order for the team to take on a high-stress job in week i, it’s required that they do no job (of either type) in week i ? 1; they need a full week of prep time to get ready for the crushing stress level. On the other hand, it’s okay for them to take a low stress job in week i even if they have done a job (of either type) in week i ? 1. So, given a sequence of n weeks, a plan is specified by a choice of “low-stress,” “high-stress,” or “none” for each of the n weeks, with the property that if “high-stress” is chosen for week i > 1, then “none” has to be chosen for week i ? 1. (It’s okay to choose a high-stress job in week 1.) The value of the plan is determined in the natural way: for each i, you add li to the value if you choose “low-stress” in week i, and you add hi to the value if you choose “high-stress” in week i (You add 0 if you choose “none” in week i.)The problem. Given sets of values l1, l2, · · · , ln and h1,h2, · · · ,hn, find a plan of maximum value. (Such a plan will be called optimal.)Example. Suppose n = 4, and the values of li and hi are given by the following table. Then the plan of maximum value would be to choose “none” in week 1, a high-stress job in week 2, and low-stress jobs in weeks 3 and 4. The value of this plan would be 0 + 50 + 10 + 10 = 70.Week 1 Week 2 Week 3 Week 4l 10 1 10 10 h 5 50 5 1First try. Below is an algorithm to plan the jobs taken.For iterations i = 1 to n If hi+1 > li + li+1 thenOutput ‘‘Choose no job in week i’’ Output ‘‘Choose a high-stress job in week i + 1’’ Continue with iteration i + 2Else Output ‘‘Choose a low-stress job in week i’’ Continue with iteration i + 1End If End ForTo avoid problems with overflowing array bounds, we define hi = li = 0 when i > n.(a) (3 points) Show that the above algorithm does not correctly solve this problem, by giving an instance on which it does not return the correct answer. In your example, say what the correct answer is and also what the above algorithm finds. Now use dynamic programming. Work out an efficient algorithm that takes values for l1, l2, · · · , ln and h1,h2, · · · ,hn and returns the value of an optimal plan.(b) (2 points) Draw the linearized DAG (topological ordering) for the example in the problem statement.(c) (2 points) List down the optimal substructure for the problem.(d) (4 points) Write the recursive formulation using the substructure.(e) (3 points) Write the enumerated pseudocode of the solution.(f) (2 points) How many subproblems?(g) (2 points) What is the time per subproblem?(h) (2 points) Determine the total running time?Page 1 of 1

According to the textbook, one of the toughest problems in investigating systems requirements is ensuring that they are complete and comprehensive. Imagine that you are a systems analyst. Decide the primary way in which you would ensure that you secure the necessary information during an interview session with a client.Devise a plan for accommodating conflicting responses for the same procedure from two different people you interviewed.

Local Breach of Sensitive Online DataThe EducationS Review, a fictional company, is hit with a data breach that is making headlines. The Olianas-based educational service and test preparation provider inadvertently exposed files of at least 100,000 students in various parts of the country through its Web site. News of the breach was made public on Tuesday morning by a report in the local newspaper.The files were exposed after the company switched the Internet service providers earlier this year. The sensitive information, which included personal data such as names, birth dates, ethnicities, and learning disabilities, as well as test performance, were easily accessed through a simple Web search and were available for at least seven weeks, according to the report. None of the information was password protected and was intended only to be viewed by EducationS authors.EducationS officials told the local newspaper that access to the information was immediately shut down as soon as the company was informed about the problem. “This brings up two big questions,” said Alex Graham, a senior technology consultant with information technology (IT) security and control firm Lizos. “Are companies doing enough to protect their data? Also, do companies really need to keep all this kind of data?” A competing test preparation firm discovered the flaw. The competitor contacted the local newspaper with the story, according to Alex, who said the play-out points to the high stakes were now involved with a data breach. If companies have not heard this before, it is a huge reminder that security is important not just for the company’s customers, but for the company’s reputation as well.While the publishing of birth dates may not seem like a massive leak, Alex said the information is a good stepping-stone for someone who is attempting to steal an identity. This is the second time in a month a public breach has involved birth dates. A glitch in a test version of social networking site, Facebook, inadvertently exposed the birthdays of its 80 million members last month. Alex discovered the bug while checking Facebook’s new design. He noticed that the birth dates of some of his privacy-obsessed acquaintances were popping up when they should have been hidden. The fact that the people affected by this latest breach were children adds to the general background radiation about security, or lack thereof, of peoples’ data on the Web.
