A company has several internal-only, web-based applications on the internal network. Remote employees are allowed to connect to

the internal corporate network with a company-supplied VPN client. During a project to upgrade the internal application, contractors were hired to work on a database server and were given copies of the VPN client so they could work remotely. A week later, a security analyst discovered an internal web-server had been compromised by malware that originated from one of the contractor’s laptops.
Which of the following changes should be made to BEST counter the threat presented in this scenario? (choose one and why)

1. Create a restricted network segment for contractors and set up a jump box for the contractors to use to access internal resources.
2. Deploy a web application firewall in the DMZ to stop Internet-based attacks on the webserver.
3. Deploy an application layer firewall with network access control lists at the perimeter, and then create alerts for suspicious Layer 7 traffic.
4. Require the contractors to bring their laptops on site when accessing the internal network instead of using the VPN from a remote location.
5. Implement NAC to check for updated anti-malware signatures and location-based rules for PCs connecting to the internal network.

Answer:

The changes to BEST counter the threat presented in this scenario is  Implement NAC to check for updated anti-malware signatures and location-based rules for PCs connecting to the internal network.

Explanation:

Implementing Network access Control NAC to check for updated anti-malware signatures and location-based rules for PCs connecting to the internal network.Network Access Control (NAC) is the best reedy that will not alter the existing work schedule in place.

This approach to computer security will unify endpoint security technology such as antivirus, host intrusion prevention, and vulnerability assessment for all users and foster stronger system authentication.

NAC will reinforce and strengthen the network security in order to prevent internal server issues from any contractor or employee henceforth.

In conducting their research, economists face an obstacle that not all scientists face; specifically, in economics, it is often
algol13

Answer:

The correct answer is (B)

Explanation:

Economics is a study of the market and human behaviour. Economists usually use historical data, conduct interviews and surveys to find a pattern to predict and forecast. In economics, it is almost impractical to conduct laboratory experiments because laboratory experiments leave out various aspects of reality and leave out relevant variables. Furthermore, It is difficult to find a way to use a laboratory experiment to predict and forecast.

Honda Motor Company is considering offering a $ 1 comma 800 rebate on its​ minivan, lowering the​ vehicle's price from $ 29 comm
zvonat [6]

Answer:

The cost of the rebate is that Honda will sell more vehicles and lose on each additional vehicle sold.

Explanation:

The cost-benefit analysis is a systematic approach that involves finding the marginal costs and marginal benefits associated with a particular decision, and then compare the benefits against the costs to determine whether the decision should be pursued.

To determine the costs and benefits in terms of incremental profits;

Benefit = Profit of $5,090 per vehicle × 13,500 (53200 - 39700) additional vehicles sold = $68,715,000  

The cost of the rebate is that Honda will make less on the vehicles it would have sold:

Cost = Loss of $1,800 per vehicle × 39,700 vehicles that would have sold without rebate = $71,460,000.

There, Benefit - Cost = $ (68,715,000 - 71,460,000) = - $2,745,000 and offering the rebate does not look attractive.

The rebate being offered is not a good idea as the cost outweighs the benefit.

Let x be per capita income in thousands of dollars. Let y be the number of medical doctors per 10,000 residents. Six small citie
MAVERICK [17]

Answer:

The percentage of variation esplained by the model is given by the determination coefficient, on this case:

R^2 = 0.934^2 =0.872

And we have 87.2% of the variation explained by the linear model given.

\hat y = 5.756(8.5) -36.895=12.031

And we have 12.031 doctors per 10000 residents.

Explanation:

Assuming the following dataset:

x                 y

8.6           9.6

9.3           18.5

10.1          20.9

8.0           10.2

8.3           11.4

8.7            13.1

Assuming this question: "The data has a correlation coefficient of r = 0.934. Calculate the regression line for this  data. What percentage ofvariation is explained by the regression line? Predict the number of doctors per 10,000 residents in a town with a per capita income of $8500."

We want a linear model like this:

y = mx +b

Where m represent the slope and b the intercept for the linear model. And we cna find the slope and b with the following formulas:

m = \frac{n \sum xy - \sum x \sum y}{n \sum x^2 -(\sum x)^2}

b = \frac{\sum y}{n} -m \frac{\sum x}{n}

And from the dataset we have the following values:

n= 6, \sum x =53, \sum y = 83.7 , \sum xy = 755.89, \sum x^2 = 471.04

And replacing into the equation for m we got:

m =\frac{6(755.89) - (53)(83.7)}{6(471.04) -(53)^2}=5.756

And the intercept:

b = \frac{83.7}{6}-36.895 5.756 \frac{53}{6}=-36.895

And then the linear model is given by:

\hat y = 5.756 x -36.895

We can find the estimation replacing x = 8.5 into the linear model and we got:

\hat y = 5.756(8.5) -36.895=12.031

And we have 12.031 doctors per 10000 residents.

The percentage of variation esplained by the model is given by the determination coefficient, on this case:

R^2 = 0.934^2 =0.872

And we have 87.2% of the variation explained by the linear model given.
