Answer:
Using a one time password OTP and using a three factor authentication.
Explanation:
Social engineering is a form system and network attack, drafted by an attacker, to steal user credentials needed for accessing their accounts, to steal information.
Social engineering attacks like phishing, spear phishing, baiting and quid quo pro are used to fool users to giving out their user details.
One time password is an implied use of a password just once and a new password his generated to boost security. In a three factor authentication, OTP can be used as well as biometrics of a user which can not be giving away by a user to an attacker.
Answer:
The program to calculate factor can be given as:
Program:
#include <stdio.h> //include header file
int main() //defining main function
{
int a,i; //defining integer variable
printf("Enter any number: "); //print message
scanf("%d",&a); //input value from user end
for(i=1;i<=a;i++) //loop for calculate factor values
{
if(a%i==0) //define condition for factor
{
printf("%d\n",i); //print values
}
}
return 0;
}
Output:
Enter any number: 15
1
3
5
15
Explanation:
In the above C language program the header file is include that provide the use of basic function, in the next line the main method is defined, inside this method two integer variable "a and i" is defined in which variable a is used to take value from user end and variable i is used in loop and conditional statement.
- In the next step, for loop is declare, that start from 1 and end with value of variable a, inside a loop, if block is used that checks (a%i==0), in this if variable i value modeler value equal to 0.
- The loop will use the print function that prints variable "i" element in a new line, which is the factor the values.
