Research via the internet and find an article in the news regarding wireless hacking, hardware hacking, or other security breach. As security and IT changed so rapidly, your article should be no older than 2007 (i.e. Less than 5 years old). Summarize the article using at least 500 words.
Hi, I provided some explanation of key terms.
Explanation:
Wireless hacking: basically the term refers to any unethical activity carried over a radio wave-connected network (eg Internet or Wifi connection) that would provide unauthorized access to information.
Hardware hacking: On the other hand, hardware hacking involves resetting physical hardware with the objective of using it in a way not originally intended by the manufacturer.
write a programmimg code in c++ for school based grading system, the program should accept the subject in the number of students from a user and store their details in the array of type student(class) the student class you have:
1. number student name, index number remarks as variables of type string, marks as integer and grade as char.
2. avoid function called getData which is used to get student details
3. avoid function called calculate which will work on the marks and give the corresponding great and remarks as given below on
Marks 70-100 grade A remarks excellent Mark 60-69 Grade B remarks very good marks 50-59 grade C remarks pass maths 0-49 grade F remarks fail
Answer:
The program is as follows:
#include <iostream>
#include <string>
using namespace std;
class Student{
string studName, indexNo, remarks; int marks; char grade;
public:
void getData(){
cin.ignore();
cout<<"ID: "; getline(cin,indexNo);
cout<<"Name:"; getline(cin,studName);
cout<<"Marks: ";cin>>marks; }
void calculate(){
if(marks>=70 && marks<=100){
remarks ="Excellent"; grade = 'A'; }
else if(marks>=60 && marks<=69){
remarks ="Very Good"; grade = 'B'; }
else if(marks>=50 && marks<=59){
remarks ="Pass"; grade = 'D'; }
else{
remarks ="Fail"; grade = 'F'; }
cout << "Grade : " << grade << endl;
cout << "Remark : " << remarks << endl; }
};
int main(){
int numStudents;
cout<<"Number of students: "; cin>>numStudents;
Student students[numStudents];
for( int i=0; i<numStudents; i++ ) {
cout << "Student " << i + 1 << endl;
students[i].getData();
students[i].calculate(); }
return 0;}
Explanation:
This defines the student class
class Student{
This declares all variables
string studName, indexNo, remarks; int marks; char grade;
This declares function getData()
public:
void getData(){
cin.ignore();
Prompt and get input for indexNo
cout<<"ID: "; getline(cin,indexNo);
Prompt and get input for studName
cout<<"Name:"; getline(cin,studName);
Prompt and get input for marks
cout<<"Marks: ";cin>>marks; }
This declares funcion calculate()
void calculate(){
The following if conditions determine the remark and grade, respectively
if(marks>=70 && marks<=100){
remarks ="Excellent"; grade = 'A'; }
else if(marks>=60 && marks<=69){
remarks ="Very Good"; grade = 'B'; }
else if(marks>=50 && marks<=59){
remarks ="Pass"; grade = 'D'; }
else{
remarks ="Fail"; grade = 'F'; }
This prints the grade
cout << "Grade : " << grade << endl;
This prints the remark
cout << "Remark : " << remarks << endl; }
};
The main begins here
int main(){
This declares number of students as integer
int numStudents;
Prompt and get input for number of students
cout<<"Number of students: "; cin>>numStudents;
This calls the student object to declare array students
Student students[numStudents];
This is repeated for all students
for( int i=0; i<numStudents; i++ ) {
Print number
cout << "Student " << i + 1 << endl;
Call function to get data
students[i].getData();
Call function to calculate
students[i].calculate(); }
return 0;}

Write a program that creates an an array large enough to hold 200 test scores between 55 and 99. Use a Random Number to populate the array.Then do the following:1) Sort scores in ascending order.2) List your scores in rows of ten(10) values.3) Calculate the Mean for the distribution.4) Calculate the Variance for the distribution.5) Calculate the Median for the distribution.
Answer:
Explanation:
The following code is written in Python. It uses the numpy import to calculate all of the necessary values as requested in the question and the random import to generate random test scores. Once the array is populated using a for loop with random integers, the array is sorted and the Mean, Variance, and Median are calculated. Finally The sorted array is printed along with all the calculations. The program has been tested and the output can be seen below.
from random import randint
import numpy as np
test_scores = []
for x in range(200):
test_scores.append(randint(55, 99))
sorted_test_scores = sorted(test_scores)
count = 0
print("Scores in Rows of 10: ", end="\n")
for score in sorted_test_scores:
if count < 10:
print(str(score), end= " ")
count += 1
else:
print('\n' + str(score), end= " ")
count = 1
mean = np.mean(sorted_test_scores)
variance = np.var(sorted_test_scores, dtype = np.float64)
median = np.median(sorted_test_scores)
print("\n")
print("Mean: " + str(mean), end="\n")

What is the easiest way to deploy a C++ program to a user’s computer? a. Copy the source code to the user’s computer and then compile it b. Create a batch file that copies the program to the user’s computer and then run it c. Copy the executable file to the user’s computer d. Create an installer program and then run it on the user’s computer
Answer:
c. Copy the executable file to the user’s computer
Explanation:
When you run a c++ program, an executable file (.exe) is created in the same directory with the source file.
To deploy this program on another system, you need to transfer the executable file from the original system where the program was executed to the new system.
The program will work fine without errors.
However, do not mistake the executable file for the source file. The source file ends in .cpp.

A computer has many resources. A resource can be memory, disk drive, network bandwidth, battery power, or a monitor. It can also be system objects such as shared memory or a linked list data structure. This principle is based in object-oriented programming (OOP). In OOP, a class definition encapsulates all data and functions to operate on the data. The only way to access a resource is through the provided interface. Which security principle are we referring to
Answer:
The security principle being referred to here is:
Resource Encapsulation.
Explanation:
Resource Encapsulation is one of the cybersecurity first principles. It allows access or manipulation of the class data as intended by the designer. The cybersecurity first principles are the basic or foundational propositions that define the qualities of a system that can contribute to cybersecurity. Other cybersecurity first principles, which are applied during system design, include domain separation, process isolation, modularization, abstraction, least principle, layering, data hiding, simplicity, and minimization.
