2. input in the hash algorithm
Explanation:In a hash algorithm, a function called hash function (say H) is chosen to transform a variable sized input n, and return a fixed size string called the hash value (say h). i.e
H(n) => h
Comparing this to the birthday attacks;
i. the hash function is getting the people's birthdays - H,
ii. the input is each person in the group of people - n,
iii. the hash is the value of the birthday of each person - H(n).

An organization's IRP prioritizes containment over eradication. An incident has been discovered where an attacker outside of the organization has installed crypto-currency mining software on the organization's web servers. Given the organization's stated priorities, which of the following would be the NEXT step?
a. Remove the affected servers from the network.
b. Review firewall and IDS logs to identify possible source IPs.
c. Identify and apply any missing operating system and software patches
d. Delete the malicious software and determine if the servers must be reimaged
Answer:
a. Remove the affected servers from the network.
Explanation:
An organization's incident response process (IRP) can be defined as all of the process involved in the cleanup and recovery of data when they fall victim to an attack or cybersecurity breach. The incident response process comprises of six (6) important stages and these are;
1. Preparation.
2. Detection and analysis (identification).
3. Containment.
4. Eradication.
5. Recovery.
6. Review of incident activities.
When an organization's IRP prioritizes containment over eradication and an incident is discovered, where an attacker outside the organization installed a crypto-currency mining software on the organization's web servers. Given the organization's stated priorities, the cybersecurity engineer should remove the affected servers from the network.
A containment process is focused on taking steps to eliminate or contain the attack. It basically involves acting swiftly in response to the attack, so as to prevent it from spreading across board or in order to mitigate the damage already caused.
In this context, the cybersecurity engineer should remove the affected servers from the network in accordance with the organization's IRP priority (containment).
Furthermore, he could take a step further to contain the attack by installing a firewall and updating their policies in the Intrusion Prevention System (IPS) of the organization.

Assume that a program consists of integer and floating-point instructions. 60% of the total execution time is spent on floating point instructions and the remaining 40% is on integer instructions. How much faster should we run the floating-point instructions to execute entire program 1.25 times faster
Answer:
the floating-point instructions should be run 1.5 times faster in order to execute entire program 1.25 times faster
Explanation:
Given that:
a program consists of integer and floating-point instructions. 60% of the total execution time is spent on floating point instructions and the remaining 40% is on integer instructions.
Let the integer be the total execution time = V
The floating-point instructions = 60%
The integer instruction = 40%
The time spent on the floating-point instruction = 60/100 × V
= 0.6 V
The time spent on t he integer instruction = 40/100 × V
= 0.4 V
However; How much faster should we run the floating-point instructions to execute entire program 1.25 times faster
If we are to execute the entire program 1,25 times faster;
The new execution time = V/1.25
Assuming the new time spent on floating-point instruction = W
∵
W + 0.4 V = V/1.25
W = V/1.25 - 0.4 V
W = (V - 0.5V)/1.25
W = 0.4V
the new time spent on floating-point instruction = W = 0.4 V
The speed required to make the floating -point instruction to run faster = 0.6V/.4 V
= 1.5
Hence, the floating-point instructions should be run 1.5 times faster in order to execute entire program 1.25 times faster
Assume that to_the_power_of is a function that expects two integer parameters and returns the value of the first parameter raised to the power of the second parameter. Write a statement that calls to_the_power_of to compute the value of cube_side raised to the power of 3 and that associates this value with cube_volume.
Answer:
The statement in python is as follows:
to_the_power_of(cube_side,3)
Explanation:
As stated as the requirement of the code segment, the statement takes as parameters a variable cube_side and a constant 3.
It then returns the volume of the cube; i.e. cube raise to power 3
See full program below
def to_the_power_of(val,powe):
result = val**powe
print(result)
cube_side = float(input("Cube side: "))
to_the_power_of(cube_side,3)

Implement the function is_maxheap which takes a list of integers and returns True if the list represents a valid max-heap, and False otherwise. Assume that the list represents the contents of a complete binary tree, following the parent/child indexing conventions established in class. E.g., is_maxheap should return True for the following inputs: a) [] b) [10] c) [10, 7, 8] E.g., is_maxheap should return False for the following inputs: a) [1, 2] b) [5, 6, 3] You should not define or use any external data structures in your implementation besides the list passed in.
Answer:
I am writing a Python function:
def is_maxheap(list):
#finds the length of the list
size=len(list)
#loop has a variable i which starts traversing from root til end of last #internal node
for i in range(int((size - 2) / 2) + 1):
if list[2 * i + 1] > list[i]: #If left child is greater than its parent then return #false
return False
if (2 * i + 2 < size and
list[2 * i + 2] > list[i]): #checks if right child is greater, if yes then #returns false
return False
return True
Explanation:
The function is_maxheap() traverses through all the internal nodes of the list iteratively. While traversing it checks if the node is greater than its children or not. To check the working of this function you can write a main() function to check the working on a given list. The main() function has a list of integers. It then calls is_maxheap() method by passing that list to the function. The program displays a message: "valid max heap" if the list represents valid max-heap otherwise it returns invalid max heap.
def main():
list = [10,7,8]
size = len(list)
if is_maxheap(list):
print("Valid Max Heap")
else:
print("Invalid Max Heap")
main()

import java.util.*;
public class Nums {
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
System.out.println("1.");
int userNum;
System.out.print("Enter Integer: ");
userNum = input.nextInt();
System.out.println("You entered: "+userNum);
System.out.println("2.");
System.out.print("Enter Integer: ");
userNum = input.nextInt();
System.out.println("You entered: "+userNum);
System.out.println(userNum+" squared is "+(userNum * userNum));
System.out.println("And "+userNum+" cubed is "+(userNum * userNum * userNum)+"!!");
System.out.println("3.");
System.out.print("Enter Another integer: ");
int userNum2 = input.nextInt();
System.out.println(userNum+" + "+userNum2+" is "+(userNum + userNum2));
System.out.println(userNum+" * "+userNum2+" is "+(userNum * userNum2));
}
}
Explanation:
This enables the program accept inputs
Scanner input = new Scanner(System.in);
This signifies the beginning of number 1
System.out.println("1.");
Variable userNum is declared as type integer
int userNum;
The line prompts the user for input
System.out.print("Enter Integer: ");
The line accepts the input
userNum = input.nextInt();
This line displays user input
System.out.println("You entered: "+userNum);
This signifies the beginning of number 2
System.out.println("2.");
This line prompts the user for input
System.out.print("Enter Integer: ");
This line accepts input
userNum = input.nextInt();
This line prints user input (as required in number 2)
System.out.println("You entered: "+userNum);
This line calculates and prints the square of user input
System.out.println(userNum+" squared is "+(userNum * userNum));
This line calculates and prints the cube of user input
System.out.println("And "+userNum+" cubed is "+(userNum * userNum * userNum)+"!!");
This signifies the beginning of number 3
System.out.println("3.");
This line prompts the user for another integer value
System.out.print("Enter Another integer: ");
This line accepts the input from the user
int userNum2 = input.nextInt();
This line adds the two inputs by the user and displays the result
System.out.println(userNum+" + "+userNum2+" is "+(userNum + userNum2));
This line multiplies the two inputs by the user and displays the result
System.out.println(userNum+" * "+userNum2+" is "+(userNum * userNum2));

What happens if you attempt an operation that uses the input stream and the operation fails but the stream is OK
Answer:
The fail bit of the stream object will be set.
Explanation:
The Input Stream is been used to effectively and efficiently read data from a source .
Therefore in a situation in which an individual or a person attempt an operation that uses the input stream and the operation fails but the stream is OK this means that the fail bit of the stream object will be set . FAILBIT is generally set in a situation where the error that occured involves the loss of integrity of the stream in which it is more likely to persist even if various operation is been carried out or attempted on the stream which is why FAIL BIT can always be checked independently by calling the member function bad.
Lastly FAILBIT is as well set because of a read or write operation that fails.
A vowel word is a word that contains every vowel. Some examples of vowel words are sequoia, facetious, and dialogue. Determine if a word input by the user is a vowel word.
Answer:
vowels = ("a", "e", "i", "o", "u")
word = input("Enter a word: ")
is_all = True
for c in vowels:
if c not in word:
is_all = False
if is_all == True:
print(word + " is a vowel word.")
else:
print(word + " is not a vowel word.")
Explanation:
Initialize a tuple, vowels, containing every vowel
Ask the user to enter a word
Initially, set the is_all as True. This will be used to check, if every vowel is in word or not.
Create a for loop that iterates through the vowels. Inside the loop, check if each vowel is in the word or not. If one of the vowel is not in the vowels, set the is_all as False.
When the loop is done, check the is_all. If it is True, the word is a vowel word. Otherwise, it is not a vowel word.
6. A distribution consists of three components with frequencies 200, 250 and 300 having means
25,10, and 15 and standard deviations 3, 4, and 5 respectively.
Calculate
The mean?
The standard deviation?
Answer:
The mean = 16
The standard deviation = 7.19
Explanation:
N1 = 200 X1 = 25 σ1 = 3
N2= 250 X2 = 10 σ2 = 4
N3 = 300 X3= 15 σ3 = 5
The mean of a combined distribution is given by:
[tex]X = \frac{X_1N_1+X_2N_2+X_3N_3}{N_1+N_2+N_3}\\X = \frac{25*200+10*250+15*300}{200+250+300}\\X=16[/tex]
The differences from the mean for each component are:
[tex]D_1 = 25-16=9\\D_2=10-16=-6\\D_3=15-16=-1[/tex]
The standard deviation of a combined distribution is given by:
[tex]\sigma=\sqrt{\frac{N_1(\sigma_1^2+D_1^2)+N_2(\sigma_2^2+D_2^2)+N_3(\sigma_3^2+D_3^2)}{N_1+N_2+N_3}}\\\sigma=\sqrt{\frac{200(3^2+9^2)+250(4^2+(-6)^2)+300(5^2+(-1)^2)}{200+250+300}}\\\sigma=\sqrt{\frac{18000+13000+7800}{750} }\\\sigma=7.19[/tex]
The mean = 16
The standard deviation = 7.19

Calculator Create a program that calculates three options for an appropriate tip to leave after a meal at a restaurant.
Specifications:
a. The program should calculate and display the cost of tipping at 15%, 20%, or 25%.
b. Assume the user will enter valid data.
c. The program should round results to a maximum of two decimal places.
Answer:
I am writing a Python program:
print("Tip Calculator \n")
bill = float(input("Cost of meal: "))
tip15pc = bill * 0.15
tip20pc = bill * 0.20
tip25pc = bill * 0.25
print("\n15%")
print("Tip amount: %.2f"% (tip15pc))
print("Total amount: %.2f \n" % (bill + tip15pc))
print("20%")
print("Tip amount: %.2f"% (tip20pc))
print("Total amount: %.2f \n" % (bill + tip20pc))
print("25%")
print("Tip amount: %.2f"% (tip25pc))
print("Total amount: %.2f" % (bill + tip25pc))
Explanation:
The program first prints the message: Tip Calculator
bill = float(input("Cost of meal: ")) This statement prompts the user to enter the amount of the bill of meal. The input value is taken as decimal/floating point number from user.
tip15pc = bill * 0.15 This statement calculates the cost of tipping at 15%
tip20pc = bill * 0.20 This statement calculates the cost of tipping at 20%
tip25pc = bill * 0.25 This statement calculates the cost of tipping at 25%
print("\n15%") This statement prints the message 15%
print("Tip amount: %.2f"% (tip15pc)) this statement displays the amount of tip at 15% and the value is displayed up to 2 decimal places as specified by %.2f
print("Total amount: %.2f \n" % (bill + tip15pc)) This statement prints the total amount by adding the cost of mean with the 15% tip amount.
The program further computes the the amount of tip at 20% and 25%. The resultant values are displayed up to 2 decimal places as specified by %.2f Then the program prints the total amount by adding the cost of mean with the 20% and 25% tip amounts just as computed for the 15% tip.
The screenshot of the program as well as its output is attached.

Explanation:
[1] The number of super keys of a relation R(A, B, C, D) with keys {A} and {B, C} is 10. The super keys of the given relations are {A}; {A, B}; {A,C}; {A,D}; {A,B,C}; {A,B,D}; {A,C,D}; {A,B,C,D}; {B,C}; {B,C,D}.
[2] key is used to uniquely identify entity from entity set. So key for every entity is unique. Subentities can have different attributes. Also functional dependencies can be different but natural join with their super subsets will be same.
[3] For a relation R to be in BCNF it must be in 3NF but If a relation R is in 3NF it is not necessary that it will be in BCNF.
[4] The natural join of relations R and S is expressed by R ✕ S.
[5] If tuple constraint references an attribute R.A to S.B then every time a change is done in R.A the tuple constraint is checked.
The key schedule results in generating multiple keys from the one secret key. These multiple keys are used:
a. in multiple sessions of communications one after the other. For example, if someone has 12 keys, they can use it for twelve video calls one after the other.
b. such that one of them is picked up at random at a time.
c. some as private keys, some as public keys.
d. for different rounds of encryption for the same plaintext to strengthen the cipher.
Answer:
Option(d) is the correct answer to the given question .
Explanation:
There are various type of algorithm is used for the purpose of the key scheduling such as AES .in the AES algorithm we used same key for encryption and decryption of text .The main objective of the AES algorithm it is used by Various round of the similar plain text encryption to reinforce the cipher text.
The Option (a) is wrong because In the key scheduling the creating keys are not being used one after just another in the various communication cycles.The Option (b) is wrong because In the key scheduling we do not used the the random key for the encryption process .The Option (c) is wrong because we will never arbitrarily subdivided into groups of public and private key.
Explain what a honeypot is. In your explanation, give at least one advantage and one disadvantage of deploying a honeypot on a corporate network.
Answer:
A honeypot is a computer network set up to act as a decoy to track, deflect, or research trying to obtain unwanted access to the information system.
Explanation:
A honeypot is a device or device network designed to imitate possible cyber-attack targets. It can be utilized to detect or deflect assaults from a legitimate military target. It may also be used to collect knowledge on how cybercrime works.
Advantage:-
Data Value:- One of the challenges faced by the research community is to obtain meaning from big data. Companies hold large quantities of data daily including firewall logs, device logs, and warnings for vulnerability scanning. Resources:- The problem facing most protection systems is resource shortages or even the depletion of resources. Power saturation is when a protection asset can no longer work since it is overloaded by its assets. Simplicity :- I find simplicity to be the biggest single strength of honeypots. No flashy techniques are to be created, no stamp computer systems to be managed, no rule units to be misconfigured.Disadvantage:-
That honeypot doesn't replace any safety mechanisms; they just operate with your overall security infrastructure and improve it.
#Write a function called 'string_type' which accepts one #string argument and determines what type of string it is. # # - If the string is empty, return "empty". # - If the string is a single character, return "character". # - If the string represents a single word, return "word". # The string is a single word if it has no spaces. # - If the string is a whole sentence, return "sentence". # The string is a sentence if it contains spaces, but # at most one period. # - If the string is a paragraph, return "paragraph". The # string is a paragraph if it contains both spaces and # multiple periods (we won't worry about other # punctuation marks). # - If the string is multiple paragraphs, return "page". # The string is a paragraph if it contains any newline # characters ("\n"). # #Hint: think carefully about what order you should check #these conditions in. # #Hint 2: remember, there exists a count() method that #counts the number of times a string appears in another #string. For example, "blah blah blah".count("blah") #would return 3.
Answer:
I am writing a Python program:
def string_type(string):
if string=="": //if the string is empty
return "empty"
elif string.count(".")>1: #if the period sign occurs more than once in string
if string.count("\n"): #checks if the new line occurs in the string
return "page" #if both the above cases are true then its a page
return "paragraph" # if the period sign condition is true then its a para
elif string.count(" ")>=1: #if no of spaces in string occur more than once
return "sentence" #returns sentence
elif len(string)==1: # if length of the string is 1 this
return "character" #returns character
else: #if none of the above conditions is true then its a word
return "word" #returns word
Explanation:
def string_type(string): this is the definition of method string_type which takes a string as argument and determines whether the type of string is a word, paragraph, page, sentence or empty.
if string=="" this if condition checks if the string is empty. If this condition is true then the method returns "empty"
elif string.count(".")>1 This condition checks if the string type is a paragragh
string.count(".")>1 and if string.count("\n") both statements check if the string type is a page.
Here the count() method is used which is used to return the number of times a specified string or character appears in the given string.
Suppose the string is "Paragraphs need to have multiple sentences. It's true.\n However, two is enough. Yes, two sentences can make a paragraph."
The if condition first checks if count(".")>1 which means it counts the occurrence of period i.e. "." in the string. If the period occurs more than once this means it could be a page. But it could also be a paragraph so in order to determine the correct string type another if statement if string.count("\n") inside elif statement determines if the string is a page or not. This statement checks the number of times a new line appears in the string. So this distinguishes the string type paragraph from string type page.
elif string.count(" ")>=1: statement determines if the string is a sentence. For example if the string is "i love to eat apples." count() method counts the number of times " " space appears in the string. If the space appears more than once this means this cannot be a single word or a character and it has more than one words. So this means its a sentence.
elif len(string)==1: this else if condition checks the length of the string. If the length of the string is 1 this means the string only has a single character. Suppose string is "!" Then the len (string) = 1 as it only contains exclamation mark character. So the method returns "character" . If none of the above if and elif conditions evaluates to true then this means the string type is a word.
Answer:
def string_type(string):
if string=="": //if the string is empty
return "empty"
elif string.count(".")>1: #if the period sign occurs more than once in string
if string.count("\n"): #checks if the new line occurs in the string
return "page" #if both the above cases are true then its a page
return "paragraph" # if the period sign condition is true then its a para
elif string.count(" ")>=1: #if no of spaces in string occur more than once
return "sentence" #returns sentence
Explanation:
a. Write out a structure called GroceryItem that contains two fields: a string (name) that contains the name of the grocery item and a float (cost) that stores the cost of the item.
b. Write out how you would create a variable of type GroceryItem called apple. Write two more lines of code that would set apple’s name to "Granny Smith" and apple’s cost to 0.79.
c. Now, write out a line of code that would create an array of 20 GroceryItem structures called, inventory.
d. Write the two lines of code that would
i. set the name of 6th GroceryItem in the array, inventory, to be "Cheese"
ii. set the cost of the 11th GroceryItem in the array, inventory, to be 3.50.
Answer:
a) struct GroceryItem{
string name;
float cost; };
b) GroceryItem apple;
apple.name = "Granny Smith";
apple.cost = 0.79;
c) GroceryItem inventory[20];
d) inventory[5].name = "Cheese";
inventory[10].cost = 3.50;
Explanation:
a) GroceryItem is the name of the structure and struct is a keyword which is used to create GroceryItem structure.
The structure has two members one is name of type string which means its holds the name strings of items. The other is cost which is a float type variable which supports floating point numbers and its holds the cost of item.
b) GroceryItem apple statement means that a variable apple is created which is of type GroceryItem
apple.name = "Granny Smith" This statement uses the apple to access the member variable name of GroceryItem structure and sets the apples's name to Granny Smith. The dot between apple variable and member variable name is basically used to access the member variable name of GroceryItem .
apple.cost = 0.79; This statement uses the apple variable to access the member variable cost of GroceryItem structure in order to set the apples's cost to 0.79. The dot between apple variable and member variable cost is basically used to access the member variable cost of structure.
c) GroceryItem inventory[20]; This statement creates an array of GroceryItem structure. The array name is inventory and [20] is basically specifies the size of this array which is 20.
d) inventory[5].name = "Cheese"; This statement uses inventory array and access the name member of the structure GroceryItem to set the name of the 6th GroceryItem in inventory array to "Cheese". .Here [5] is the index of the 6th item of the inventory array as the array locations start from 0. So inventory[20] can contains 20 elements from 0 index to 19 index. So to set the name of 6th item 5th index is specified.
inventory[10].cost = 3.50; This statement uses inventory array and access the cost member of the structure GroceryItem to set the cost of the 11th GroceryItem in inventory array to "3.50". Here [10] is the index of the 11th item of the inventory array as the array locations start from 0. So inventory[20] can contains 20 elements from 0 index to 19 index. So to set the cost of 11th item 10th index is specified
