Write a 2- to 4-page paper summarizing the known operating system security flaw in Microsoft® Windows®, Mac OS X®, Linux®, or UNIX®. Describe the type of flaw or condition within the OS that allowed the attack and how the flaw was addressed or countered.

Need full credit on this. So must be A+ work and not a copy of already used work. I will let you decide the price for the paper but will not go over $20 for it.
