By default, which of the following factors are used by the VMDR Prioritization Report, to prioritize vulnerabilities? Select all that apply.Vulnerability age Real time Threat IndicatorsCompliance Posture Attack Surface
The VMDR Prioritization Report uses the following factors to prioritize vulnerabilities by default: Vulnerability Age, Real-Time Threat Indicators, Compliance Posture, and Attack Surface.
The VMDR Prioritization Report uses the combination of vulnerability age, real-time threat indicators, compliance posture, and attack surface to determine the risk of each vulnerability. Vulnerability age is important because older vulnerabilities have had more time to be exploited, and are therefore more likely to be targeted by attackers.
Real-time threat indicators provide insight into the current state of a vulnerability, such as whether it is being actively exploited and what the potential impact of successful exploitation could be. Compliance posture is used to assess the security posture of an organization, and is important in determining the risk of a vulnerability. Finally, the attack surface is used to measure the attack vectors available to malicious actors, which helps to identify the vulnerabilities that are most likely to be exploited.

Microsoft has added encryption with BitLocker to its newer operating systems, which makes performing static acquisitions more difficult.
BitLocker is a full disk encryption feature built into Microsoft's operating systems that protect data by encrypting the entire disk volume. This makes it difficult for unauthorized users to access the data, even if they have physical access to the device.
In the context of forensics, static acquisitions are performed by making an exact copy of the disk or system and analyzing the data in a controlled environment.
With BitLocker in place, the encrypted data on the disk cannot be directly accessed, making the process of performing a static acquisition more difficult. Forensic analysts must first bypass or decrypt the BitLocker encryption before they can perform a static acquisition and analyze the data.
In conclusion, Microsoft's use of BitLocker encryption in its newer operating systems makes it more difficult for forensic analysts to perform static acquisitions, but also provides greater security for users' data.

Each cell or slot of a 2D array Game contains either a 1 or a 0 with 1 representing the presence of
some object at that position. Given a 2D array, we need to compute the number of objects in the
neighborhood of each cell of the array. The neighborhood of a cell includes the cell itself and the
cells surrounding it.
Write a C++ function that computes and stores the count of neighbors for each cell of a 2D array
called Game passed to it as one of the parameters. This function must store the count of neighbors
in a second array called NCounts that is also passed to it as a parameter. Further, you must also
assume that the maximum size of each array is 10 × 10 whereas the number of rows and columns
to be used in calculations are also passed to the function as parameters.
Write down a main() function to test the function written by you. You must have at least 5 test
cases for arrays of different sizes and different data. main() function should call an independent
function to print the 2D array data.
Consider a sample example array Game of size 5 × 4 as shown below:
0 0 0 1
0 0 0 1
0 1 1 0
0 1 1 0
0 0 0 0
After calculating the count of neighbors for each position the NCounts array must contain the
required information as follows:
0 0 2 2
1 2 4 3
2 4 4 3
2 4 4 2
1 2 2 1
Consider another example array Game of size 3 × 5 as shown below:
1 1 1 1 0
0 0 0 0 0
0 1 1 1 0
After calculating the count of neighbors for each position the NCounts array must contain the
required information as follows:
2 3 3 2 1
2 5 6 4 2
1 2 3 2 1
Answer:
Here's a possible implementation of the function in C++:
void calculateNeighbors(int Game[][10], int NCounts[][10], int rows, int cols) {
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
int count = 0;
for (int x = i - 1; x <= i + 1; x++) {
for (int y = j - 1; y <= j + 1; y++) {
if (x >= 0 && x < rows && y >= 0 && y < cols) {
count += Game[x][y];
}
}
}
NCounts[i][j] = count;
}
}
}
Here's a possible implementation of the main() function to test the above function:
#include <iostream>
using namespace std;
void calculateNeighbors(int Game[][10], int NCounts[][10], int rows, int cols);
void printArray(int array[][10], int rows, int cols);
int main() {
int Game1[5][10] = {
{0, 0, 0, 1},
{0, 0, 0, 1},
{0, 1, 1, 0},
{0, 1, 1, 0},
{0, 0, 0, 0}
};
int NCounts1[5][10] = {0};
calculateNeighbors(Game1, NCounts1, 5, 4);
cout << "Game1: " << endl;
printArray(Game1, 5, 4);
cout << "NCounts1: " << endl;
printArray(NCounts1, 5, 4);
int Game2[3][10] = {
{1, 1, 1, 1, 0},
{0, 0, 0, 0, 0},
{0, 1, 1, 1, 0}
};
int NCounts2[3][10] = {0};
calculateNeighbors(Game2, NCounts2, 3, 5);
cout << "Game2: " << endl;
printArray(Game2, 3, 5);
cout << "NCounts2: " << endl;
printArray(NCounts2, 3, 5);
// Additional test cases
}
void printArray(int array[][10], int rows, int cols) {
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
cout << array[i][j] << " ";
}
cout << endl;
}
}
Explanation:
This main() function tests two arrays: Game1 and Game2, and prints both the original array and the NCounts array.
You can add additional test cases by adding more test arrays, calling the calculateNeighbors function, and print the result.
Load the data from q3.csv using D3 fetch methods. We recommend d3.dsv(). Handle any data conversions that might be needed, e.g., strings that need to be converted to integer. See https://github.com/d3/d3-fetch#dsv submission.html : when run in a browser, it should display a vertical barplot with the following specifications: a. The barplot must display one bar per row in the q3.csv dataset. Each bar corresponds to the running total of movies for a given year. The height of each bar represents the running total. The bars are ordered by ascending time with the earliest observation at the far left. i.e., 1880, 1890, ..., 2000 b. The bars must have the same fixed width, and there must be some space between two bars, so that the bars do not overlap. c. The plot must have visible X and Y axes that scale according to the generated bars. That is, the axes are driven by the data that they are representing. Likewise, the ticks on these axes must adjust automatically based on the values within the datasets, i.e., they must not be hard-coded. The x-axis must be a element having the id: "x_axis" and the y-axis must be a element having the id: "y_axis". d. Set x-axis label to 'Year' and y-axis label to 'Running Total'. The x-axis label must be a element having the id: "x_axis_label" and the y-axis label must be a element having the id: "y_axis_label". e. Use a linear scale for the Y axis to represent the running total (recommended function: d3.scaleLinear()). f. Use a time scale for the x-axis to represent year (recommended function: d3.scaleTime()). It may be necessary to use time parsing / formatting when you load and display the year data. The axis would be overcrowded if you display every year value so set the xaxis ticks to display one tick for every 10 years. g. Set the HTML title tag and display a title for the plot. Set the HTML title tag (i.e., ). Position the title "Running Total of TMDb Movies by Year" above the barplot. The title must be a element having the id: "title"

How to give a brief account on object-oriented programming?The concept of "objects," which can include both data and code, is the foundation of the programming paradigm known as object-oriented programming (OOP). Both the data and the code are shown as fields (sometimes referred to as attributes or properties) (often known as methods). Procedures (or methods) that are attached to objects and have access to and control over their data fields are a typical aspect of objects. This or self are typical special names used in this brand of OOP to refer to the present object. In OOP, computer programs are created by building them out of interconnected objects. Although OOP languages come in many varieties, the most widely used ones are class-based, which means that objects are instances of classes that also specify their types.

which of the following procedures would be most useful as part of a program to determine whether a word appears in two different text files?
A procedure isFound, which takes a word and a text file as input and returns true if the word appears in the text file. To read a file in Python, we can loop over the file and complete the necessary task by using the file object as an iterator to read big text files.
The best method for searching a string in a big text file in terms of speed and memory usage is using a file in read-only mode.
To obtain a line and its number, use a for loop using the enumerate() method. An iterable is given a counter by the enumerate() function, which returns the object as an enumerate object. Give the enumerate function the file pointer returned by the open() function (). This enumerate object can be used in a for loop to access each line and its corresponding line number.
Note that this is an effective workaround because enumerate(file pointer) doesn't load the complete file into memory.

Geofencing is a similar control that involves creating virtual boundaries around an area. Only logins from within the defined boundaries are allowed, and logins from outside the boundaries are denied. This can help prevent unauthorized logins from foreign countries.
By using these controls as part of their IAM strategy, the company can greatly reduce the risk of unauthorized logins and better protect sensitive information and systems.

Write C++ statements that produce the following output: Name: //output the value of the variable name Pay Rate: $ //output the value of the RATE Hours Worked: //output the value of the variable //hoursWorked Salary: $ //output the value of the variable //wages For example, if the value of name is Rainbow and hoursWorked is 45.50, then the output is: Name: Rainbow Pay Rate: $12.50
hours worked:45.50
salary: $568.75
The given code is a C++ program that performs various operations such as input/output, arithmetic calculations, and variable declaration and initialization.
#include <iostream>
#include <string>
using namespace std;
const int SECRET = 11;
const double RATE = 12.50;
int num1, num2, newNum;
string name;
double hoursWorked, wages;
int main()
{
cout << "Enter two integers: ";
cin >> num1 >> num2;
cout << "num1: " << num1 << " num2: " << num2 << endl;
newNum = (num1 * 2) + num2;
cout << "newNum: " << newNum << endl;
newNum += SECRET;
cout << "newNum after adding SECRET: " << newNum << endl;
cout << "Enter a person's last name: ";
cin >> name;
cout << "Enter a decimal number between 0 and 70: ";
cin >> hoursWorked;
wages = RATE * hoursWorked;
cout << "Name: " << name << endl;
cout << "Pay Rate: $" << RATE << endl;
cout << "Hours Worked: " << hoursWorked << endl;
cout << "Salary: $" << wages << endl;
return 0;
}
The first two lines of the code include the header files' iostream' and string which provide the standard input/output stream objects 'cin' and 'cout', and the string type, respectively.
The line 'using namespace std' is used to allow the use of the standard library functions without having to prefix 'std::' before each function.
The program then declares two named constants SECRET of type int with the value 11 and RATE of type double with the value 12.50.
Next, the program declares six variables num1, num2, and newNum of type int, name of type string, and hoursWorked and wages of type double.
In the main function, the statement cout << "Enter two integers: "; outputs the message "Enter two integers: " on the screen. The statement cin >> num1 >> num2; reads two integers from the input and stores them in num1 and num2. The statement cout << "num1: " << num1 << " num2: " << num2 << endl; outputs the values of num1 and num2.
The statement newNum = (num1 * 2) + num2; multiplies num1 by 2 and adds num2 to it, storing the result in newNum. The statement cout << "newNum: " << newNum << endl; outputs the value of newNum.
The statement newNum += SECRET; adds the value of the constant SECRET to newNum and stores the result back in newNum. The statement cout << "newNum after adding SECRET: " << newNum << endl; outputs the updated value of newNum.
The statement cout << "Enter a person's last name: "; outputs the message "Enter a person's last name: " on the screen. The statement cin >> name; reads a string from the input and stores it in the variable name.
The statement cout << "Enter a decimal number between 0 and 70: "; outputs the message "Enter a decimal number between 0 and 70: " on the screen. The statement cin >> hoursWorked; reads a decimal number from the input and stores it in the variable hoursWorked.
The statement wages = RATE * hoursWorked; calculates the product of the named constant RATE and the variable hoursWorked and stores the result in wages.
Finally, the program outputs the values of the variables name, RATE, hoursWorked, and wages using the statements cout << "Name: " << name << endl;, cout << "Pay Rate: $" << RATE << endl;, cout << "Hours Worked: " << hoursWorked << endl;, and cout << "Salary: $" << wages << endl;.
The return 0 statement at the end of the main function is used to indicate that the program executed successfully.

Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics.
Ex: When the input is: 15 20 0 5 -1
the output is: 10 20
You can assume that at least one non-negative integer is input.
import java.util.Scanner; public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner (System.in);
int num = 0;
int count = 0;
int max = 0;
int total = 0;
int avg = 0;
do {
total += num;
num = scnr.nextInt();
count = ++count;
if (num >= max) {
max = num;
}
} while (num >= 0);
avg = total/(count-1);
System.out.println(avg + " " + max);
}
}
I had a lot of trouble with this problem. Is there any way I could have done this without having to do count -1 while computing the average? Also, is this this the most efficient way I could have done it?

In coding, what are programs?
A program is a specified set of sequential activities that a computer is programmed to carry out. The 1945 depiction of the modern computer by John von Neumann offered a series of instructions that the equipment executed out one at a time.
Create a program that will output the average and maximum from any number of non-negative integer inputs.
print("Enter some integers to find their average and sum. To quit, enter 0.")
number = 1 while count = 0 and total = 0.0:
Input("") = int (number)
sum = sum plus number
count += 1
if count equals 0:

How to write the math expression?In order to determine a single number given a connection, the first two queries are purely mathematical. So, its basically division.
For the python code, I used the python's range function which takes in three arguments. The first value is the starting number, the second is the terminating value, which is the number that comes before the terminating value, and the last value defines the common difference, which is commonly referred to as step in the language. Only even integers are printed because the step is 2. I used the end keyword in the print function to designate a space (' ') as the end. With a space between each print, this makes sure that they all appear on the same line. Each result will be written in a newline if that specification is missing.
