Firewall is the technology that is commonly used to prevent unauthorized traffic from entering

or exiting an organization's network. Firewalls often establish a barrier between a trusted

internal network and untrusted external network, such as the internet. Firewalls often work

through monitoring and logging to record events that occur on or across a network. Firewall

logging ensures that the defined filters or rules are adequate and functioning as expected. By

monitoring traffic stream through a firewall's filtering scheme, it is possible to identify the

types of traffic that the firewall should block.

Question 10 3 / 4 points

LO10: As a faculty member for the Lone Star Education Services (private education organization with less than 100 employees that focuses on online learning), you've been placed on a committee tasked with evaluating Learning Management Systems. Each system presented has similar features that encompass the majority of the stated needs of your organization, with the turnkey solution checking the most boxes, however the price for the turnkey Learning Management System software is upwards of $100,000 per year. Two additional options are presented to the committee. An open-source software that does not cost to license but has a more limited feature set or you could develop the software in-house. In general, what would be the best recommendation based on the information provided? Option 1 - Turnkey solution, Option 2 - Open Source with modifications, Option 3 - Develop In-house. Explain your answer.

Question 12 0 / 4 points

Access Control

Option 2 (open source with modifications) would be more prudent than developing an in-

house or opting for a Turnkey solution, which is costly for a small organization with only 100

employees. By embracing the outsourced with modifications, the organization can

concentrate, the organization can concentrate its resources on its core business competencies

while capitalizing on the expertise of other firms that are more effective and efficient, or more

knowledgeable on the specialized tasks. Further, the open source with modification options

can provide the organization with access to current technologies at low costs without the risks

of obsolescence. In so doing, the organization can cut costs by gaining capabilities without

incurring overhead costs.

There are various potential challenges that each business is likely to encounter when engaging

in partnerships with foreign firms. For instance, the task of monitoring and regulating

businesses may be challenging. Such challenges may include concerns over intellectual

property violations, taxation systems, security concerns, as well as privacy of each business

entity. Such problems are often rampant in global business contexts in which laws and ethics

that govern businesses often conflict rather than compliment each other.

There are various potential ethical concerns related to Facebook's data harvesting practices.

One such ethical concern is confidentiality. The harvesting of personal data may spark

confidentiality issues, especially when they are disclosed to unauthorized parties. Additionally,

data harvesting may spark privacy concerns, especially when such data are used to track and

monitor the private activities of individuals and groups. Furthermore, issues such as espionage

and wrong use of data may arise. For instance, some malicious people may use such data to

commit fraud and crimes, such as impersonating individuals after gaining access to their

financial and personal information.

LO2: Your coworker, Fred, describes an issue he is facing with his computer. He states that the computer will start but as soon as he plugs in an external drive it crashes. He notes that he installed a new internet browser after he performed a Windows system update the week before. Fred blames the crashes on the new internet browsing application. Select the most accurate statement below.

Question 16 0 / 4 points

LO2: Which of the following is not a feature of enterprise resource planning (ERP)?

Question 17 0 / 4 points

LO8: Business process reengineering employs the following idea;

The application is most likely not the cause of the problem because the operating system is responsible for managing the external device and the application described does not directly interface with the drive when the crash occurs.

The internet browser application is most likely the problem because of the timing of the install and nature of the crashes.

Neither the application or the Windows update installed are likely to have anything to do with the crash.

Operating Systems such as Windows provide no direct communication with external drives, therefore the application is most likely the culprit of Fred's recent crashes.

LO1: Applying Moore's Law to the following situation, what assumption can we make. (Moore's law has been dissipating in recent years but for the sake of this question, assume that it fully applies.)

Our IT department has determined that they will need an additional 5 servers with max processing power at current technology capabilities. At current prices the IT department determines the cost will be about $100,000. We only have $50,000 in our budget but we are not in a rush. When are we likely to be able to purchase these machines and why?

LO5: What event lead to the first implementation of an Internet?

may include database system installation and maintenance, data backup and recovery, data

development and testing, securing database system, as well as authentication.

Very quick and repetitive decisions (Decisions that need to be made immediately based on a known set of inputs)

None of the above

Semi-structured decisions (Most of the factors are known but human interaction is still needed)

Complex decisions (Decisions in which machine learning is necessary to reduce human error)

Moore's law operates in the assumption that the number of transistors on a microchip doubles

every two years, although the cost of computers is halved. According to Moore's law, the

speed and capability of computers is projected to increase every two years, and people will

pay less for them. This growth is exponential. Currently, the servers cost $100,000. However,

the price, based on Moore's law is projected to half after two years. As such, the organization

is likely to afford to buy it at $50,000 after two years, which will be in 2022.
