Chapter 3, Problem 1.4AYK

1. Explain in detail with examples each of the following fundamental security design principles: economy of mechanism, fail-safe default, complete mediation, open design, separation of privilege, least privilege, least common mechanism, psychological acceptability, isolation, encapsulation, modularity, layering, and least astonishment.

Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity. Justify your answers.

Please include comments and docs comments on the program.    The two other classes are Attraction and Entertainment.

Object-Oriented Programming In this separate files. ent, you'll need to build and run a small Zoo in Lennoxville. All classes must be created in Animal (5) First, start by building a class that describes an Animal at a Zoo. It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo! Build a class…

[10 pts] Minimize the Boolean equation you obtained in (a). b. [10 pts] Implement, using Logisim, the simplified logic circuit. Include an image of the circuit in your report. 2. [20 pts] Student A B will enjoy his picnic on sunny days that have no ants. He will also enjoy his picnic any day he sees a hummingbird, as well as on days where there are ants and ladybugs. a. Write a Boolean equation for his enjoyment (E) in terms of sun (S), ants (A), hummingbirds (H), and ladybugs (L). b. Implement in Logisim, the logic circuit of E function. Use the Circuit Analysis tool in Logisim to view the expression, include an image of the expression generated by Logisim in your report. 3.[20 pts] Find the minimum equivalent circuit for the one shown below (show your work): DAB C…

When using functions in python, it allows us tto create procedural abstractioons in our programs. What are 5 major benefits of using a procedural abstraction in python?

Find the error, assume data is a string and all variables have been declared. for ch in data:         if ch.isupper:             num_upper = num_upper + 1         if ch.islower:             num_lower = num_lower + 1         if ch.isdigit:             num_digits = num_digits + 1         if ch.isspace:             num_space = num_space + 1

Find the Error: date_string = input('Enter a date in the format mm/dd/yyyy: ') date_list = date_string.split('-') month_num = int(date_list[0]) day = date_list[1] year = date_list[2] month_name = month_list[month_num - 1] long_date = month_name + ' ' + day + ', ' + year print(long_date)

Find the Error:       full_name = input ('Enter your full name: ')       name = split(full_name)       for string in name:         print(string[0].upper(), sep='', end='')         print('.', sep=' ', end='')
