I don’t know how to handle this Operating Systems question and need guidance.

Topic 1: Low Rate Wireless Personal Area Networks (LR WPANs)

A wireless personal area network (WPAN) is a personal area network for interconnecting devices centered around an individual’s workspace. A Wireless Personal Area Network (PAN) uses two kinds of wireless technologies, Bluetooth, Infrared Data Association (IrDA) and Zigbee. List the different WPAN standards and their applications and explain how each work

Topic 2: High Rate Wireless Personal Area Networks (HR WPANs)

High-rate wireless personal area networks (WPANs) operate in the 2.4 GHz band supporting data speeds ranging from 11 Mbps to 55 Mbps. The high-data rates provide wireless connectivity of multimedia-capable wireless devices. Describe the characteristics required by 802.15.3 applications.

PLEASE ANSWER THE LISTED BELOW:

• List the different LR WPAN standards and their applications.
• Explain how IrDA, Bluetooth, and ZigBee work.

I have attached the text-book of course and this assignment in chapter 2.

You have been asked to draft a letter to guests to address concerns about the impacts of possible cyber attacks. This particular letter should reassure guests that the company is taking positive steps to protect guest privacy. The guests’ concerns extend beyond privacy of information in databases. There have been news reports detailing situations where hackers have attacked internal building monitoring and control systems to spy on guests and invade their privacy.

In order to write an effective notification letter, it is first necessary to understand the required perspective for such a letter.

From a technical perspective, this type of attack is a data security problem because the attackers are stealing data by attacking at the point of creation (data at rest) and then along the transmission paths (data in transit). The impact of this type of attack is a loss of confidentiality.

From a people perspective, this type of attack is viewed as an attack on the privacy of guests and is categorized as a loss of privacy.

Managers need to address this problem from both perspectives. With internal technical staff, the conversation would revolve around data security. But, with guests and Guest Relations staff, the conversation needs to address concerns about the possible loss of privacy.

Secondly, we must consider the required “tone” for such a letter. The letter must be factual but, more importantly, it is necessary to show an appropriate amount of empathy and understanding for the recipient’s feelings. Empathy and emotional intelligence are important leadership skills for managers.

Having empathy and/or acting in an empathetic manner (aware of and sensitive to the emotions of guests and customers), allows a manager to respond appropriately when a cyberattack occurs. As you write this letter, you will need to find a balance between addressing the emotional aspects of a cyberattack (need for a supportive and calming response — less information may be best) and the need to develop trust by providing information about a situation that can invoke fear and concern.

read this definition of Emotional Intelligence and this discussion article about What Emotional Intelligence Is and Is Not. Then, read about three types of empathy https://www.huffingtonpost.com/entry/types-of-empathy_us_56f171cde4b03a640a6bcc17.

Next, read one or more of these articles about a cyber attack that affected hotel operations and created fear and concern among guests and employees.

1. Hackers use ransomware to target hotel guests’ door locks

2. Hackers are using hotel Wi-Fi to spy on guests, steal data

3. 20 hotels suffer hack costing tens of thousands their credit card information

Using what you’ve learned about data security AND emotional intelligence, draft a letter that Padgett-Beale could use to inform and calm its guests should a similar cyberattack (door locks, guest WiFi access, or credit card Point-of-Sale breach) affect one of the company’s hotel properties. Your draft letter will also be used to train employees in how they can and should respond to guest concerns.

The purpose of this assignment is to identify social media data collection strategies and the legal and ethical issues associated with social media data mining.

Part 1

Conduct research to identify how business organizations mine social media to collect data so they can obtain a competitive advantage in the marketplace. Locate examples of several strategies and companies. You cannot use examples already referenced in the study materials. Research the legal and ethical issues that are associated with data mining activities, including specific laws that govern data mining and examples of companies that have faced legal issues and negative consequences as a result of ethical issues resulting from the data mining strategies they employed.

Create a PowerPoint presentation (minimum of eight content slides) that summarizes your findings and addresses the following. Include a reference slide at the end of the presentation.

1. Describe strategies business organizations use to mine social media to collect data and provide supporting examples.
2. Discuss how the data that are mined via social media can be used to create a competitive advantage for the business organizations.
3. Describe legal issues associated with business data mining activities, including specific laws governing data mining practices.
4. Provide an example of a company that faced legal issues as a result of the data mining strategies it employed.

I’m attaching 2 lecture Power Point which you need to Write a critical analysis of the lecturevideos provide reply’s with 250 to 300

TASK 2

A fundamental component of internal control is the separation of duties for high-risk transactions. The underlying separation of duties concept is that no individual should be able to execute a high-risk transaction, conceal errors, or commit fraud in the normal course of their duties.

You can apply separation of duties at either a transactional or an organizational level. For example, payroll has access to employee financial records, but only payroll managers can approve raises.

Answer the following question(s):

1. do you define a high-risk transaction?
2. If you were a security professional in a company, what are four roles (two sets of two related roles) you would separate and why? Provide examples not mentioned in the description for this discussion.

Need Primary post – 350 -400 words.

Once you send primary post. I will attach 2 secondary post which you need to provide reply’s with 150 to 250 words

D-Assignment 1

Web server auditing can go a long way in enforcing tighter security and ensuring business continuity. The power of log data is tremendous. Web server logs record valuable information pertaining to usage, errors, and other important security events. Using a specialized auditing tool can be extremely helpful during the audit of web servers. In your discussion this week, please discuss the methods of identifying weak web server configurations and how to mitigate them for a secure web server. Possible concepts to include are SSL certificates, HTTPS usage, attack surface, SQL injection, vulnerability migration, and least privilege. In at least one of your peer responses, provide an overview of how to audit the web server’s security and implement best practices.

Explain, define, or analyze the topic
