The Most Secure Buildings

We are focusing on access control. Do some Internet research to identify what some people consider the most secure buildings in the world. These might be military, political, financial, religious, or some other purpose. Pick one location and describe the location, its security protections, and how people are authenticated and permitted (or denied) access to the building. If you are unable to confirm some of these details for your chosen location, prescribe them based on your understanding.

Users and Groups

In this week, we will again use our virtual machine. This time, we will be creating two users and granting selected permissions from one user to the other.

First, create a new user with “useradd -m <username>”. Then, repeat the command for a second user. Set a password for each user with “passwd <username>”.

Next, we will create a group for our users with “groupadd <groupname>”. Add your users to the group with “usermod -G <groupname> <username>”.

Test out logging in as your first user with the command “su – <username>”. Next, we will create three files using the following commands:

  • echo “first file” > file1
  • echo “second file” > file2
  • echo “third file” > file3

You can validate the contents of file1 with “cat file1”. Let’s validate the file permissions of our files with “ls -l”. Take a screenshot of the output. Every file has nine permissions, ignoring the first one. The first three are for the user, the next three are for the group, and the final three are for others.

Next, we are going to adjust permissions so that:

  • File1 is only readable and writeable to user1
  • File2 is readable and writeable to user1 and members of the group to which you added both users 
  • File3 is readable by all users, but writeable only by user1

To make these changes, you’ll use the “chmod” command to adjust permissions, and you’ll need to add file2 to the group our users are in using “chown :<groupname> file2”. To use the chmod command, there are two syntaxes: octal syntax and letter syntax. We are going to use the letter syntax in these examples. If you know octal syntax, feel free to use that instead.

The format is going to be “chmod <who><operation><permissions> <filename>”. The <who> value will be one of u for user, g for group, o for others, or a for all. The <operation> will be + to add permissions and – to remove permissions. The <permissions> will be any of r for read, w for write, or x for execute. Set the permissions of the files to the bulleted list above. Validate your permissions with “ls -l” and take a screenshot of the output.

Then, switch to the second user account and verify the permissions using the following commands.

  • cat file1
  • cat file2
  • cat file3
  • echo “first file” > file1
  • echo “second file” > file2
  • echo “third file” > file3

Take a screenshot of the results of these commands. If the results don’t match expectations, you can switch back to your user1 and adjust permissions again to get it right.

In your submission, include:

  • Screenshot of “ls -l” output before changing permissions
  • Screenshot of “ls -l” output after changing permissions
  • Screenshot of the validation commands as user2

Parameters

  • The assignment should be double-spaced, 12-point Times New Roman font, with one-inch margins
  • Use APA for citing references and quotations
  • See the assignment rubric below for more details

cpsc 1050 networking data packets

 

  1. Start the “TCP/IP” (reliable connection simulator) applet.
  2. In the text field labeled “Your message:”, type the following: “Computer networking is essential in our world today.“. Then press the button “Send a message.”
  3. Watch the entire sequence of packets that are sent for the sample message. How many “DAT” packets were sent? How many “ACK” packets were sent?
  4. If each character or blank in a packet header counts for one character, and all “DAT” packets except the last carry 10 characters (including the blanks), and “ACK” packets have no data characters (though they do have a header), count up how many characters were sent in total.
  5. There are 52 characters in the above message, including blanks and punctuation. Subtract 52 from the total number of characters sent in both directions in all packets. Divide this number by the total number of characters to get the overhead (those characters which are not really data but yet you have to transmit them), represented as a percentage.
  6. Imagine that you have a million-character message to send, perhaps a large file. How many characters in total (and to your best estimate) would be sent in all packets necessary to move it from node 0 to node 1?
  7. What would be an obvious way to decrease the overhead?
  8. Repeat Steps 1 and 2.
  9. Select “Delete packets that are touched“.
  10. Delete some data packets by clicking on them as they move along the wire and watch the retransmission after timeout.
  11. What happens if you delete the re-transmitted packet?
  12. Now try deleting some ACK or NAK packets. What happens?
  13. See if you can compute the checksum as TCP/IP does. Run the applet, using any message. Select a data packet, but don’t select the last packet because it might be too short, less than 10 characters. Count up the characters, including blanks. If they do not equal 10, assume there are blanks at the end so that the character count is 10.
  14. Using the “Text Encoding in ASCII” applet, type in the characters from the data packet, and click on “translate text“.
  15. Add up the values for each of the characters. Then calculate the modulus of this number using 256.
  16. Compare your manually computed checksum for the first packet of the message “Introduction to Computer Science” against what the applet shows for the packet. Do they match?
  17. Now damage your packet by altering one character. Re-compute the checksum. You should realize how the applet can spot errors.
  18. Think of a way that a packet can be damaged and still have the same checksum as the undamaged version. Give one example for this scenario.

Cloud Expansion Discussion

PowerPoint Presentation Project

Valencia is expanding its services into international markets opening markets in Ireland and Vietnam, and the projections are now twofold. After exhaustive research, you came up with the notion of using cloud computing technologies, and you have determined that this technology offers the best alternative for keeping the current customer and project requirements. you have been directed to analyze the situation and come up with a proposed solution for the chief information officer (CIO) and the sales manager. The time to implement is measured in months, not in years.

You also observed, during your research on cloud computing, that as enterprises move more of their IT resources to the cloud, protecting against security breaches is a top concern. IT executives often cite worries over security as a reason why they are not taking greater advantage of cloud services.

Your job is to persuade top management, including the sales manager, that this technology does the following:

  • Offers the best solution in terms of cost, time to implement, and sustain.
  • Reduces the cost of added infrastructure and technical personnel to maintain.
  • Safeguards the privacy and confidentiality of customers’ data and helps protect organizational information from cyberattacks.

Oral Communication Parameters and Expectations:

  • The presentation must be at least 6–8 content slides long, with each slide having narration in Standard English explaining the key ideas in each slide.
  • In addition to the content slides, the presentation must include the title and reference slides.
  • The oral presentation should have a highly developed and sustained viewpoint and purpose.
  • Oral communication should be highly ordered, logical, and unified.
  • The oral delivery technique, including word choice and oral expressiveness, must display exceptional content, organization, and style while leading the audience to a dynamic and supported conclusion.
  • The narration must provide clear enunciation, a professional tone, and no background noise.
  • The communication must be free of grammatical errors and show no evidence of plagiarism.

Assignment Requirements

  • You may use a theme provided with MS PowerPoint to format your presentation, or you may create your own style. A consistent background for all slides works best.
  • Use text and background colors that provide sufficient contrast for readability. Dark text against a light background works well, but avoid extremes like black on white, vibrant or neon colors, or clashing contrasts like blue on red.
  • Use a consistent, plain font such as Arial, Times New Roman, or Verdana throughout, and a readable font size such as 20 or 24.
  • The presentation should contain sufficient information to adequately support the narration and contain no spelling, grammar, or APA errors. Remember that the slides will contain summary information of what you provide in your narration. Points deducted from grade for each writing, spelling, or grammar errors are at your instructor’s discretion according to the Undergraduate Writing Rubric located in Course Resources.
  • Include both APA style in-text citations and a reference page for any sources you use to support your argument.
