  2. First things first…

  3. Ethical Hacking • Be responsible • Don’t use hacking for evil • It’s easy to be caught, and the penalties are very steep Guideline: Never hack someone’s system without their permission

  4. Why do ethical hackers hack? • It’s fun • “War games.” Companies hire ethical hackers to hack into their systems so that the companies can learn how to improve their defenses • Ethical hackers develop defensive technology • Every coder should know how to hack, so that they know how to write “secure code” (which is code that can defend itself from hackers)

  5. How to hack? • Hacking = manipulating a system to do something it wasn’t designed to do • Like hot wiring a car http://commons.wikimedia.org/wiki/File:Dash_Wires.jpg • Hacking computers is often simple (once you know how computers work)

  6. How do computers work?For example: What happens when you type google.comin your browser? • There is a computer on the Internet whose address is google.com • Your computer sends a “request” to that computer • The google.com computer computes a “response” and sends it back to your computer • Your computer shows the response on your screen google.com computes the response this response is a web page: request Just like requesting a person to compute something for you

  7. Example DoS attack • DoS = denial of service • Send a request for a very difficult computation • It might crash the computer • The Air Force once challenged me to hack their radar. That’s how I did it. http://www.ll.mit.edu/mission/cybersec/publications/publication-files/full_papers/2010_06_25_Gagnon_ISARCS_FP.pdf http://commons.wikimedia.org/wiki/File:C-band_Radar-dish_Antenna.jpg

  8. Hack my server! • You have my permission to try to crash: http://hackerpuzzle.herokuapp.com • But I won’t tell you how • It’s a puzzle

  9. I repeat: • Be responsible • Don’t use hacking for evil • It’s easy to be caught, and the penalties are very steep Guideline: Never hack someone’s system without their permission

  10. Teach yourself to hack • It can be a career • Learn everything you can about how computers work • Learn to code • Learn math (algebra, calculus, statistics, and beyond) • Experiment a lot • Find hacking challenges on the Web • Be tenacious • Be patient • Be ethical
