Returns True after converting the image to monochrome.

All plug-in functions must return True or False. This function returns True

because it modifies the image. It converts the image to either greyscale or

sepia tone, depending on the parameter sepia.

If sepia is False, then this function uses greyscale. For each pixel, it computes

the overall brightness, defined as

0.3 * red + 0.6 * green + 0.1 * blue.

It then sets all three color components of the pixel to that value. The alpha value

should remain untouched.

If sepia is True, it makes the same computations as before but sets green to

0.6 * brightness and blue to 0.4 * brightness.

Parameter image: The image buffer

Precondition: image is a 2d table of RGB objects

Parameter sepia: Whether to use sepia tone instead of greyscale

Precondition: sepia is a bool

Week 11 Discussion

Read this Time article and view the video explaining how Russian trolls spread fake news.  Discuss in 500 words whether the government should regulate Facebook more closely.  
Use at least three sources. Use the Research Databases available from the Danforth Library, not Google.   Include at least 3 quotes from your sources enclosing the copied words in quotation marks and cited in-line by reference to your reference list.  Example: “words you copied” (citation) These quotes should be one full sentence not altered or paraphrased. Cite your sources using APA format. Use the quotes in your paragraphs. Do Not Doublespace.

You are requested to write review, survey or state-of-art article. The article has to give an overview of existing literature in a field, often identifying specific problems or issues and analyzing information from available published work.

This is a literature review paper

Ten of references must to be from journal articles published in well publishers’ databases; IEEE, Springer, Elsevier, Wiley and Taylor & Francis.

Business Case: Local Hospital’s data center

Companies spend billions on security each year, yet why is this still an issue? It’s almost 2019 and still, most applications are horribly insecure and security best practices are not followed. Applications are designed for functionality, not security because security is seen as difficult and time-consuming, often blamed for adding delays to product launches and revenue-generating activities. Assume; you are an IT manager at the regional Hospital and answer the following questions.

Where the Local Hospital’s parameters are:  600 patients a day, and 250 full-time employees. The hospital has a data cent with all IT assets (Databases, Servers, Data storage, Network devices) to support the Hospital’s Business operations.

QUESTION 1: There is a need for a new posture for cybersecurity in a networked world where your hospital is part of it.  What are principles used by some of the world’s leading cybersecurity teams at global companies to archive this goal?

How can you adapt the principles for your hospital case?

QUESTION 2: Companies should assess threats and develop controls for the most critical assets.

If the threats against tour Hospital IT System are 

Manipulation of software

Unauthorized installation of software

Misuse of information systems

Denial of service

What would be controls that you should apply to mitigate above listed risks?

QUESTION 3: As an IT manager, you were tasked to develop an information security and risk management (ISRM) strategy which requires a multiphase approach. What are the phases that would should follow to provide recognizable results and value to the Hospital?

Topic: Quantitative v. Qualitative security risk assessment

Your Research Project is due this week. It must consist of:

1. 5 sources annotated bibliography( In this case, write two paragraphs about each source. The first is a summary of what the source informs and the second is why it is valuable.)

2. Summary or Abstract containing at least 850 words.

essay (500 words) and 3 responses (100 words each)

 Chapter 6 topics:

• Define and describe a SAN.
• Define and describe NAS.
• Describe how cloud-based data storage works.
• Assume that you must select a cloud-based data storage solution for your company. List the factors you would consider when selecting a vendor.

 Chapter 7 topics:

• Define collaboration.
• Define and describe cloud-based collaboration.
• The CIO of Ace Accounting Services suggests that the company can save considerable money using VoIP for phone calls. Define and describe VoIP. Then present three companies that provide VoIP offerings. Compare and contrast each company’s offering. Also, discuss whether or not you agree with the CIO and justify why.
• List the questions one should consider when evaluating a cloud-based collaborative solution.

Take the following set of Pseudocode and make a flowchart as well as an output sample using the visual logic program:
Begin parcelCharges
 

Calculate delivery_charge
Prompt parcel for weight in kilograms (kg)
Get parcel_weight
If parcel_weight <2.5 THEN
delivery_charge = $3.50 * parcel_weight
else
If parcel_weight <= 5 THEN
delivery_charge = $2.58 * parcel_weight
else
delivery_charge = $2.45 * parcel_weight
ENDIF
ENDIF
Display “Delivery charge for parcel is”, delivery_charge
