The effect of computer hacking on national security is a very pressing issue in today’s time especially because each generation is becoming more and more adept in using advanced technology. Everyday technology is progressing and because of this we have to be aware of computer hackers. “A computer hacker is a person who finds out weaknesses in the computer and exploits it.” (“Hacker”, 2012). These hackers have threatened national security by hacking into governmental records and have even initiated animosity between countries (“French Finance Ministry Suffers Cyber-attack”, 2011). The specific purpose of this paper is to inform the audience that the effect of hacking on national security greatly impacts nations in negative ways.
