A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly restricted in that it always operates on precisely the range 1 to 10. List different ways that this program can be sabotaged so that during execution it computes a different sum, for example, 3 to 20.

See explanation section

Explanation:

See the program at the end of this solution

The program can be sabotaged if the source file is altered before running the program.

Take for instance,

Someone changes

for(int i =k;i<=n;i++)

to

for(int i =3;i<=20;i++)

This implies that no matter the user input, the program will only calculate the sum of 3 to 20

It is also possible that the program is altered by an external process.

Take for instance;

n = 10

k = 1

And the sum has been calculated for the range of k = 1 to 5.

Then the program is altered by an external process.

15 (sum of 1 to 5) will be displayed instead of 55 (sum of 1 to 10)

Program written in C++

#include<iostream>

using namespace std;

int main() {

int k.n,total=0;

cin>>k;

cin>>n;

//Assume k will always be less than n

for(int i =k;i<=n;i++) {

total+=i;

}

System.out.print(total);

return 0;

}

this seems to be in the wrong category. but i'll take some free points my dude

posting this in wrong category will result in people seeing it who won't know the answer.
