) The least-privilege principle can be used to effectively defend against the race condition attacks discussed in this chapter. Can we use the same principle to defeat buffer-overflow attacks? Why or why not? Namely, before executing the vulnerable function, we disable the root privilege; after the vulnerable function returns, we enable the privilege back.

Technician a says that the radiator usually cools better if the front air dam is removed. technician b says that when a condenser has a leak it can be repaired easily with epoxy. who is correct?

All of the following are characteristics that must be contained in any knowledge representation scheme except

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
