Could a 0xlcomputer virus that scrambled constrained data items be introduced into the system? Why or why not? Specifircally, if not, identify the precise control that would prevent it from being intorduced, and say why it would prewvent the virus from being introduced; if yes, identify the specific control or controls that allow it to be introduced @&and say why they fail to keep it out.  v( 30 points ; text, exercise 19.6) An attacker breaks into a web server using a Windows 2000 based system.
