In Class Today
• What is hacking?
• What policies and or laws exist?
• Are there any ethical issues?
ECE 4883 - Internetwork Security
2
What is Hacking?
• An event where one enjoys learning the
details of a computer system
• A culture where people find their
computer and its surroundings
fascinating.
• The process of creating a new program or
making changes to existing programs
using complicated software
ECE 4883 - Internetwork Security

Some History of Hacking
• December 1993 USENET posting by
Farmer and Venema
• Idea of using techniques of an intruder to
evaluate system security
• Approach can help companies secure
systems
• Distributed Security Analysis Tool for
Auditing Networks (SATAN)
ECE 4883 - Internetwork Security
4
Types of Hacking
• Possible categories of Hacking
 Good Hacking- work on software to improve
performance, expose system vulnerabilities, done
with company permission (security professional)
 Bad Hacking-accidental or not fully understood
damage caused by for example kiddy scripts (juvenile
delinquents)
 Dangerous Hacking- intentional damage caused by
criminals (professional criminals)
ECE 4883 - Internetwork Security
5
Ethical Hacking
• Approval from the organization inside
which the hacking will occur
• Tiger team uses tools and techniques to
evaluate security
• Inform owner of files and systems before
the fact
ECE 4883 - Internetwork Security
6
Hacktivism
• The use of hacking to promote a political
cause
• Modern form of civil disobedience
• Political form of cyber-terrorism
• A cover for ordinary pranks

Hackers
• Term coined by the media back when computer
time was stolen by unauthorized users
• Prior to this media coined term, a Hacker was:
“a person who enjoys exploring the details of
programmable systems and how to stretch their
capabilities; … one who programs
enthusiastically.”

Hacker categories:
• Novice or newbies – not sure how code
works, run kiddy scripts
• Experienced hacker – understand the
software and are able to create attack
code.
• Expert hacker – develop tool sets for
attack, create code quickly for exposed
vulnerabilities.
ECE 4883 - Internetwork Security

Hacker categories (cont):
• Internal hackers – from within a company,
could be ex-employees or current
workers,have access and knowledge
about where sensitive information is
located
• White hats – trustworthy, professional
security analysists

Hacker’s Motivation
• At one end same motivation as graffiti
• Some argue that they help find security
flaws and force improved network security
• Some are professionals and are motivated
by the profession

Learning to Hack
• Hacking Schools
 Zi Hackademy, Paris
 Civil Hackers school, Moscow
• Hacking Classes
 This class
 Government Training
 Company training

Ethical or Not?
• So who is responsible for the outcome from
these teachings?
 It’s the teachers! They are the ones teaching such
techniques and tools and inflicting painful
examinations.
 It’s the students! They are responsible for the
actions they decide to take after learning tools that
others use to attack. How can you figure out how to
defend yourself if you do not understand the attacks?
Only through knowledge can you defend yourself

•
•
Department of Homeland Security
Some call this a National Police Force
Connects 22 different Agencies

Policy Maker Questions:
• How easy is it to catch hackers and how many
hackers have been caught?
• Are these policies good enough?
• Do the current policies actually define the limits
of “hacking”?
• Can companies hack into their own systems and
find vulnerabilities?
• Can other find vulnerabilities for them without
being asked to?
ECE 4883 - Internetwork Security

What if?
• A Georgia Tech student uses their personal PC and the school’s
network to do a port scan on a commercial web site.
• A Georgia Tech student uses their personal PC and a commercial
ISP to do a port scan on a commercial web site.
• A Georgia Tech student sends a “spoofed mail” from the school
account that appears to come from another user.
• A Georgia Tech student uses a school computer and password
guessing software to access and crack the administrator password.
• A Georgia Tech student discovers that another user failed to log off
when departing. The student uses the account to send an
inflammatory email to the department chair.
