Risk Analysis
While virtualization provides numerous advantages by implementation of VMs, server virtualization does not exempt the IT systems from the risks applicable to such setup in physical environment (Cloud Security Alliance, 2015). Implementation of server virtualization may introduce new and unique security risks that may have impact that is more significant in the organization. Risks identified during the risk analysis process are as follows:
Risk no Risk Probability (1-5) Severity (1-5) Score (PxS) Action to Prevent/ Mitigate Risk
1 VM sprawl/ uncontrolled proliferation of VMs may lead to architectural and configuration risk 1 3 3 Control the creation, storage, and use of VM images with formal change management process and tools. Put effective policies and guidelines in place to govern and manage VM lifecycle.
2 VM images and snapshots containing sensitive data are not governed by policies to restrict the storage and usage that leads to risk of confidentiality and integrity 3 4 12 Encrypt the data stored in the VMs and implement a policy based key management of data stored.

Customers can make the decision whether to sign up for the Pier 1 emails or not. However, if customers decided not sign up and close the window, it is hard to find the sign up section again if they change their minds. Customers need to go all the way down to the bottom of the website to find the sign up box. The bottom sign up banner does not contain the “10% off "information.

...object is needed, such as if the sides not shown in the isometric drawing. It includes an isometric drawing plus the 2D views from each side of the object. This does not always mean three views. This object only needs two orthogonal views to fully explain it and provide every detail. There are two main methods of drawing orthographic projections. First angle projection is used in Europe and most of the world. However, America and Australia use third angle projections. 3 In a first angle drawing the object is placed in the first quadrant, with the horizontal plane underneath and the frontal plane behind. In a third angle drawing, the object is pace in the third quadrant, with the frontal plane in front and the horizontal plane above. 4 Assembly drawings or parts diagram contain all parts and sub-assemblies of a product that has more than one parts. It sometimes illustrates assembly at manufacturer-level. A BOM (bill of materials) is included on this drawing, containing each part number, name and quantity. This diagram is vital for engineers and technicians to ensure a full understanding of all the components inside a piece of equipment. 5 A wiring diagram is a drawing of an electrical circuit layout. It shows the fixtures, components and where the wires are connected to each other and to the system. It is used as a “map” during maintenance and repair. The symbols used in a wiring diagram are versions of the real-life components in the circuit. 6 Another diagram is the...

...After reading the note from the supervisor and inquiring about a room, I would make a list of the challenges that I have encountered and other considerations such as: - I have two hours to solve this challenge. - I can’t find any room available to hold the meeting in my office. - Do we need a projector and computer access in the room? - The photocopier will be down for the entire day on my floor, but I can call another department on another floor and check if I can use their photocopier. - If there are no photocopiers available, I would need to go to a stationary shop such as Office Depot to copy the documents on time. - I need money for professional copying. - If I change the location, I need to consider parking and advising the client of the change in locations. Is there paid parking? If I change the location can we contact the client in time or should the client still meet at our office? We can take the client to the new location; however, the client might have time restraints and this might extend our meeting time. - We don’t have a hospitality budget. Would my supervisor be willing to buy the client a cup of coffee? I advised my manager that I will check if I can use another department’s photocopier. While the documents are copying, I would quickly call the closest Federal Government office to see if I can book one of their meeting rooms.

...Select each control in turn and using the Properties panel change the Name of the controls to myButton, myLabel and textInput respectively. The Form design is now complete and we can now begin to connect the events to event handlers. We will begin by defining an event procedure for the TextBox. To access the textInput control event procedures simply double click on the TextBox control in the Form. Visual Studio will subsequently display the event procedures for the textInput control. By default Visual Studio picks the most common event, the TextChanged event, and creates a stub of the subroutine to be called when that event is triggered by the user. In our example we want every keystroke performed by the user in the TextBox to be displayed by the Label control. In this case the TextChanged event is exactly the event we want. If, however, we had wanted to write the procedure for a different event on the TextBox we could simply click on the right-hand drop down menu above the code area to view and select from a list of events available on this type of control: With the TextChanged event still selected it is time to write the Visual Basic code that will be executed when the event is triggered. To do so, we will need to set the Text property of the myLabel control to equal the Text property of the textInput control. The properties of objects are accessed using what is called dot notation. For example the Text property of myLabel is accessed in Visual basic code as follows: myLabel...

...Implementation: To start implementation, we first must establish what we would like to answer through our application. The scenarios are as follows: 1. When one of the followers is disconnected, how does the leader respond to the missing follower? 2. When the leader of the quorum is disconnected, how does the remaining followers respond to the missing leader? 3. What happens when that disconnected leader comes back to the quorum? 4. When one of the nodes in the quorum is disconnected, would the Kafka messaging service still work? 5. If there is only one replica of a topic on a specific server, will that topic be available if its server goes down? For the first question, we first started by starting the Zookeeper service on every server. When all the service was up and running, Zookeeper uses the FastLeaderElection algorithm to elect a leader from the quorum. To double-check that we had a quorum, we ran the command on each server to get the status of the node: echo srvr | nc localhost 2181 grep Mode As you can see from the screenshot above, the second server became our leader while the other servers acknowledged the second server as the leader, so they became the followers. When we simulate...

...employees about the mission, vision, and values of the organization and see how they understand these statements. For instance, I would ask straight forward if they can reiterate the organization’s mission statement or to list the values that organization is dependent on. Another thought could be an organization-wide meeting to share updates about how the organization is striving to reach its mission and vision. Managers also should meet with their employees and help them to achieve the organization’s mission and vision. For instance, their conversation could start by saying that “our mission revolves around quality, integrity, and patient’s safety” as well as the need to keep employees aware when they are doing a good job and rewarding them. 4. How will you demonstrate cultural competence across settings? "Cultural competence in health care describes the ability to provide care to patients with diverse values, beliefs, and behaviors, including tailoring health care delivery to meet patients' social, cultural, and linguistic needs" (Health Research & Educational Trust, 2013, June). As we become culturally diverse, it is important to incorporate cultural competence into our day-to-day lives, especially in health care setting. Further, if we are not aware of another’s culture beliefs, values or behaviors, then we have tendency to stereotype, to have biases and prejudices toward different culture other than our own. I believe, respecting, accepting, and being open minded are needed...

...NT1330 Unit 4 Assignment 1. AD Design Replication Scenario AD Design Replication Scenario To whom it may concern: I am the IT Administrator for the company and I have been asked to give my recommendations for the Active Directory Replication Design of the two new Branches. The first I can recommend for you is that all the information that is needed for each new site is correctly documented and added to the Root Active Directory through the Active Directory sites and services. This is done because the Root AD automatically builds the inter-site replication topology based on the information provided about the new site connections. Each new site’s AD will have one each domain controller that is known as the inter-site topology generator and they are assigned to build the topology at their sites. To add two new branch offices we will need to find a strategy to design a replication process. To implement this we will need to use inter-site replication. Inter-site replication is needed when adding domain controllers located in different sites. We will also need a site link (Site link is a logical, transitive connection between two sites that allows replication to occur) protocol of Remote Procedure Call (RPC) over Internet Protocol (IP) which is the preferred choice for the replication process. This allows you to communicate with network services on various computers and also keep data secure when being transmitted by using both encryption and authentication...

...1. Your client has just informed you that your project budget has been cut by 20%, you have lost 2 project team members, and your project scope will remain the same. How do you respond to this new information? What type of project constraint(s) are you up against and what steps do you take to deal with this new information? The concept of triple constraints in a project means that the three constraints in the project are interdependent. Therefore, changes in the budget are likely to impact the other constraints such as scope and time of completion. Upon receiving the information about the budget cut and the reduced workforce because of the two project members leaving, my first step would be to evaluate the impact of the changes on other constraints in the project and calculate the cost of the remaining part of the project. Since the scope is to remain the same, this means that I would be against time and cost. Based on the information provided regarding the changes, my second step after the evaluation of the impact would be to inform other stakeholders of the changes and ask them to vote on the functionality of the products expected to be realized at the end of the project. (Carstens, Richardson, & Smith, 2013) The recommendations by other stakeholders would help me understand the importance of each of the products and budget the remaining funds and allocate them to the selected project divisions based on importance. In an event that there are changes in the project, Estimate...

...such as firewalls, increases the risk of unauthorized physical access going undetected. Although there are no servers present, the network equipment is vital to the company’s operations. Unauthorized access could result in tampering with the firewalls or other network devices, potentially leading to disruptions in service, unauthorized network access, or compromising the integrity of the network. It is recommended that the company install security cameras focused on key areas where network equipment is located, such as the communication cabinet or IT equipment areas. This will act as a deterrent to unauthorized access and provide a means of monitoring and responding to any physical security incidents involving critical network infrastructure. 4. What is the difference between a.. Unchanged Wi-Fi password / password. Significant Low Significant Unauthorized access to the company's internal network. The office Wi-Fi password has not been changed for an extended period, and there is no procedure in place for regularly updating the password. While the Wi-Fi is restricted to employees only and not accessible to guests, the lack of password management increases the risk of unauthorized network access, particularly in an environment without network segmentation.

...This paper will focus on configuring print document and service. Print and services enable to concentrate print server and network printer tasks. Which also scan and fax documents from the network. The print device is the hardware that produces hard copy documents on paper. Print services enable to share printers on a network. It also enables to migrate print servers and deploy printer connections using group policy.
