 You are a member of the Human Resource Department of a medium-sized organization that is implementing a new interorganizational system that will impact employees, customers, and suppliers.  Your manager has requested that you work with the system development team to create a communications plan for the project.  He would like to meet with you in two hours to review your thoughts on the KEY OBJECTIVES OF THE COMMUNICATIONS PLAN.  What should those objectives be? 

After completing the reading this week, we reflect on a few key concepts this week:

1. Discuss the key components of human resource management.  Pick at least four concepts from chapter nine and describe how these concepts interrelate to individual performance on a team.
2. Review table 9.2 and select one of the dimensions listed, note why it was chosen and how you relate to this behavior.  If you have a personal experience, please share.
3. How do leaders select the best talent? What are some tools they can use to select the best-talent?

Define the IT organizational structure and how the IT organizational structure impacts culture and change management practices.  Additionally, how does the organizational structure impact competitive advantage?

Provide a reflection of at least 500 words (or 2 pages double-spaced) of how the knowledge, skills, or theories of this course have been applied, or could be applied, in a practical manner to your current work environment. If you are not current working, share times when you have or could observe these theories and knowledge could be applied to an employment opportunity in your field of study.   

Information security and risk management

Purpose

This discussion activity gives you the opportunity to solve a real world scenario. In doing so, you will learn the concepts of a software development cycle.

Directions

Part I: Complete Your Original Response to the Main Topic

You are a software developer for a Retail Point of Sale System Company. A client has made a request to upgrade the current system from command line interface to a graphic user interface. The client concerns on an effect to the current system with the change. The client does not want to lose any current data on the system. Provide recommendations and the change plan including the below requirements to the customer.

Requirements:

• Create a requirement plan (what need to be done to support this upgrade)
• Create a development plan (how to implement this upgrade with programming details explanation including technical details on this document)
• Create testing plan (how to ensure that the new upgrade works without affecting current system and no data lost.)

Posting your recommendations and the change plan

Once you have completed your recommendations and plan. Post it in the discussion forum by clicking the Reply link below.

• In the first line of your post, your should add your plan title and name.
• Your posting must include recommendations, a requirement plan, a development plan, and a testing plan.  

IN 250-300 words.  what a rootkit is ?

The readings this week discusses broad context of risk and investigative forensics. Part of risk management is to understand when things go wrong, we need to be able to investigate and report our findings to management. Using this research, or other research you have uncovered discuss in detail how risk and investigate techniques could work to help the organization. ERM helps to protect an organization before an attack, where as forensics investigate technique will help us after an attack – so lets discus both this week.

Please make your initial post should have 500 words and the post will do at least TWO of the following:

• Explain, define, or analyze the topic in detail
• Share an applicable personal experience
• Provide an outside source (for example, an article from the UC Library) that applies to the topic, along with additional information about the topic or the source (please cite properly in APA)

At least one scholarly source should be used in the initial discussion thread. Be sure to use information from your readings and other sources from the UC Library. Use proper citations and references in your post.

1.) In no less than 250 words, describe the difference between a fat AP and a thin AP.  What is needed to deploy a thin AP?  Are there any security considerations to think about between the 2 different APs?  Respond to two other learners by the end of the week.

2.)  Have you or someone you know ever received a chain letter, phishing message, or some other fraudulent message via email? If so, please share this experience. Explain what type of message it was and what you did to get rid of it.

3.) Answer the below questions 

1 What is the basic building block of an 802.11 WLAN?

2 Define an extended service set.

3 List and briefly define IEEE 802.11 services.

4 Is a distribution system a wireless network?

5 How is the concept of an association related to that of mobility?

6 What security areas are addressed by IEEE 802.11i?

7 Briefly describe the five IEEE 802.11i phases of operation.

8 What is the difference between TKIP and CCMP?

1.     

In this chapter we have looked at the point location problem with pre- processing. We have not looked at the single shot problem, where the subdivision and the query point are given at the same time, and we have no special preprocessing to speed up the searches. In this exercise and some of the following ones, we have a look at such problems. 

Given a simple polygon P with n vertices and a query point q, here is an algorithm to determine whether q lies in P. Consider the ray ρ := {(qx +λ,qy) : λ > 0} (this is the horizontal ray starting in q and going rightwards). Determine for every edge e of P whether it intersects ρ. If the number of intersecting edges is odd, then q ∈ P, otherwise q à∈ P. 

Prove that this algorithm is correct, and explain how to deal with degen- erate cases. (One degenerate case is when ρ intersects an endpoint of an edge. Are there other special cases?) What is the running time of the algorithm? 

2. Suppose you are given an n-vertex simple polygon, P. Describe how to build an efficient data structure for determining in O(log n) time whether a query point, q, is inside of P or not. What is the space and preprocessing time for your data structure?

3. The ray shooting problem occurs in computer graphics (see Chapter 8). A 2-dimensional version can be given as follows: Store a set S of n non-crossing line segments such that one can quickly answer queries of the type: “Given a query ray ρ—a ray is a half-line starting at some point—find the first segment in S intersected by ρ.” (We leave it to you to define the behavior for degenerate cases.) In this exercise, we look at vertical ray shooting, where the query ray must be a vertical ray pointing upwards. Only the starting point need be specified in such a query. Give a data structure for the vertical ray shooting problem for a set S of n non-crossing line segments in general position. Bound the query time and storage requirement of your data structure. What is the preprocessing time?
