 Review the attached file. Suzie has an issue. She can either move to NY or FL and needs to review some data that her agent gave her. The agent reviewed house prices and crime ratings for houses that Suzie would be interested in based on her selection criteria.  She wants to live in an area with lower crime but wants to know a few things:

1. Is it more expensive or less expensive to live in FL or      NY?  Done
2. Is the crime rate higher in FL or NY (Note a low score      in crime means lower crime)?  Done
3. Is the crime rate higher in lower or higher house price      areas?  Done

Using the R tool, show the data in the tool to answer each of the questions.  Also, show the data visualization to go along with the summary.

1. If you were Suzie, where would you move based on the      questions above? Done

Need the below done ONLY

1. After you gave Suzie the answer above (to #4), she gave      you some additional information that you need to consider:
   1. She has $100,000 to put down for the house.
   2. If she moves to NY she will have a job earning       $120,000 per year.
   3. If she moves to FL she will have a job earning $75,000       per year.
   4. She wants to know the following:
      1. On average what location will she be able to pay off        her house first based on average housing prices and income she will        receive?
      2. Where should she move and why?  Please show        graphics and thoroughly explain your answer here based on the new        information provided above.

Note: The screenshots should be copied and pasted and must be legible.  Only upload the word document.  Be sure to answer all of the questions above and number the answers.  Be sure to also explain the rational for each answer and also ensure that there are visuals for each question above.

RESPONSE 1:

The Apache web server is an open source web server that was created in 1995. With very little configuration Apache is able to handle large amounts of traffic and because of open source there are developers continuously working on updates and better functionality. Apache can also be used on multi-platforms. Apache is able to accept and route traffic to certain ports. By default it will run on port 80, but with specific address-port combinations it is able to route ports. Ways to make Apache more secure are through some of the following ways. Disabling the trace HTTP request. By default this is enabled and allow cross-site tracing that could potentially expose your cookie information. Disabling the directory listing will prevent access to the files and sub-directories within the browser. Tools that can be used to secure your Apache server are mod security that is an open source web application first this will provide you with several features designed to protect the server.  

The Microsoft Internet Information Server (IIS) has been in service since Windows Server 2003 and only operates on the Windows operating system. Like Apache you are able to route traffic to other ports. IIS benefits from being popular due to its platform that supports all the Microsoft applications. Some of the features of IIS are Remote management that allows the management of the program via command line interface or union PowerShell. IIS also comes with security features that allows users to manage TLS certificates and allows the user to filter requests that will allow for the traffic of whitelists and blacklists. These are tools that will assist in securing IIS. Disable the OPTIONS Method. The OPTIONS method gives a list of the methods supported by a web server and disabling this ensures that potential attackers won’t be able to access the information. Enable Dynamic IP address restrictions will block access to IP address that go over a certain amount of requests. This can prevent denial of service attacks.

RESPONSE 2:

Security on an Apache webserver is only as good based on its configurations.  Along with proper security configuration, it’s important to keep Apache updated with the latest security patches as they become available.  The following are some configuration changes in securing an Apache server:

Securing an Apache webserver should be configured to use only what is required for functionality. Configure on the module required to run functionality and restrict other unnecessary services.  

Run as an unprivileged user:  this refers to locking down the Apache server with minimal permission than necessary.  This would require to set the server as an unprivileged systems user versus root or admin user.

Disabling server-info directive, server signature and server-status Directive to prevent the exposure of server information, such as version, paths, data directories, server performance, HTTP requests and client IPs. 

Setting the ServerToken directive to Prod will direct Apache to a specified name, like Apache in the server response header. This prevent the server from sending server information out when responding to a request.

OpenSSL is one tool I ran into when researching Apache security.  Because Apache does not come with encryption, running OpenSSL with it can provide traffic encryption and public/private key pairs to force all traffic over SSL protocol.

A Microsoft IIS server has similar security configuration recommendations as the Apache.  These include:

Installing and properly configuring only the necessary modules required for functionality and implementing the least privileged rule. As well as enabling Window authentication with extended protection to protect against credential relaying and phishing attacks.

Maintaining an up-to-date anti-virus and security patches.  Also enabling SSL and SSL certificates.     

Web application isolation includes isolating web application pools, ASP.Net temp folders and content and ensure access controls list are configured to allow access as per set permissions.

A local small business has hired you to write a payroll calculation program.

#The program only needs to calculate gross pay for an employee and display the results.

#Your program will accept the employee’s name, hours worked, and the employee’s pay rate.

#The program will need to calculate overtime as well.

#Overtime is defined as anything over 40 hours is paid at 1.5 times the regular pay.

#The program should print the employee’s name, the gross pay amount,

#and only if there was overtime, print the overtime pay amount as well.

#Finally, the program should repeat as necessary until the user enters a sentinel value.

 Let A and B be disjoint languages, that is, A ∩ B = ∅. We say that the language C separates the languages A and B if A ⊆ C and B ⊆ C(Complement). We say that A and B are recursively separable if there is a decidable language C that separates A and B. Suppose that A(Complement) and B(Complement) are recognizable. Prove that A and B are recursively separable.
