Policy
1- You are the Information Security Director for a medium sized company. You recently experienced a ransom-ware attack that cost the company
$500,000.00. After the attack your CEO held a meeting and informed you and the other IT professionals that it “WILL” not happen again. Write a Directive to
the employees of the company summarizing the requirement for all personnel to adopt the new 2-factor authentication for IT equipment access. Include a
30-day timeline to adopt, and the consequences of not adhering to the new policy.
Cybersecurity, policy, threats, behavior, etc.
Locate an interesting topic on cybersecurity, policy, threats, behavior, etc.
Here are some pointers that will help critically evaluate some viable topics.
• Is the topic attainable for a first-time dissertation student?
• Is the problem rooted in the literature?
• Is the research empirical, i.e., is there a survey, is there an interview guide, has the data been analyzed via some statistical tool?
• Is there a theoretical model or framework discussed?
Discuss the topic, the problem the model has been used in the research, and any present findings.
The problem, policy, and political streams.
Explain the difference between the problem, policy, and political streams. What happens when all the streams come together?
Cybersecurity, policy, threats, behavior
During this semester, we reviewed a number of areas in information security and the threats that companies face, we face, the numerous threats and ways we can help to minimize these attacks.
Getting closer to your dissertation, you will need to choose a topic in your dissertation class, so it is essential to start preparing. This week, let us take a look at some topics to consider, and by the end of the week, we could have several ideas for dissertation topics
Since you have already examined several research articles, another way would be to examine previous dissertations in these areas.

Do not read the entire dissertation, as the abstract and chapter one introduction should give a clear understanding of the research.
Policy
You are a salesperson of a durable product. You rely on system recommendations to manage
procurement and selling. Yet your manager is unhappy with your performance. To save your job,
you must figure out why your performance is poor and how to improve.
The current system uses the (s, S) policy. Here s is the reordering point and S is the base-stock
level, with s ≤ S. In each period t = 1, 2, . . . , T, the system works as follows:
• PROCUREMENT: Upon observing the initial inventory level xt
, you have two situations: (i)
if xt < s, you will order Qt = S − xt , pay fixed ordering cost K, and bring the post-order inventory level yt to the order-up-to level S (i.e., yt = S); (ii) if xt ≥ s, you do not order and inventory remains yt = xt . Hence, your ordering cost is K · 1(xt < s). • SELLING: with yt inventory on hand, you satisfy customer demand Dt ∼ N (µ, σ2 ) as much as possible. There are two situations: (i) if Dt ≤ yt , the leftover inventory (yt − Dt) carries over to the next period at unit holding cost h; (ii) if Dt > yt
, the unsatisfied demand (Dt −yt)
is booked at unit backorder cost b. Hence, your inventory holding and backorder costs are1
h(yt − Dt)
- + b(Dt − yt)
+.
• The remaining inventory carries over to the next period t + 1, with initial inventory level
xt+1 = yt − Dt
.
The demand has µ = 3, σ = 1, while the cost structure has h = 1, b = 10, K = 20. The current
policy is set to s = 3, S = 15. You suspect that the current (s, S) policy is responsible for your
poor performance. To convince the manager that the policy is the culprit, you must address the
following questions, with your favorite Excel and simulation.
