- Explain Buffer Overflow Attacks and Input Validation Attacks commonly utilized on Unix OS . ( CLO 3 )4. Explore what a hacker can do to make use of the coding problem of buffer overflow.For example, consider the situation of a page fault. What part of the operating system do they have a connection to? What does this mistake suggest, in the most fundamental sense, is unclear.
