Meet Jack le Hack
Third year student : University of Cyberfucious
Putting knowledge into practice
It is Monday afternoon after a rough weekend for Jack. He is sure he
failed the test he wrote that morning as the beers he consumed made
him suffer from memory loss and he forgot to study. His finances are
also shot as he had to sponsor some of his friends for their social
activities. To boot his professor also made some comments about the
quality of his work which Jack felt was not appropriate. Jack also
assists with some classes for first year students and realises that he still
has to prepare for a lecture for the next day.
He goes to the office that was assigned to him. He shares the office with
one of the admin clerks of the faculty. When he walks past her desk, he
notices that she did not log of her computer. Jack decides that it is time
to put his master plan into action...

Meet Jack le Hack
Putting knowledge into practice ...
Jack has a fair knowledge of computers and has long since been toying
with the idea of putting this knowledge to good use.
He firstly uses the admin clerks’ mailbox to send the offending
professor a message, stating that his day will come and that he knows
where he lives and has intimate knowledge of the professor’s family. He
also stated that a bomb will go off within the next week in the
professor’s classroom.
Secondly, he logs into the shared folders of the faculty where he knows
the results of the test he wrote are kept. Jack decides that he certainly
deserves a better mark than he received that morning.

Meet Jack le Hack
When studying the test results, he sees that he was not the only one that
failed. Jack realises that this could present an opportunity to deal with
his financial difficulties. He phones some of the other students and
offers a deal to them to change their marks for a small donation.
A few days pass and Jack’s business kicks off beyond his own
expectations. He is also approached by students that have financial
difficulties and cannot pay their class fees. With a little research and
questions posed in chat rooms, he acquires the necessary information to
hack into the financial system of the university. He installs a key logger
on one of the financial clerk’s computer and so gains access to his
password. He once again accesses the system from the admin clerk’s
computer.

PwC
Meet Jack le Hack
Jack is so impressed with his own efforts that he posts this information
on Facebook and Twitter and also uses Skype to tell his friends in the
UK about his endeavours. Because his data bundle expired, he posts
this information from a computer connected to the university network
and also installed Skype on the computer. He did, however, remove
Skype from the computer later.
Life is good for our Jack le Hack.

How to protect your data
14
September 2011

PwC
• Protecting data starts with each user of a computer on your campus
and is not only related to the functions and responsibilities of the IT
department.
• Your responsibilities include:
- Protecting the university property stored on your computer,
including information about staff, faculty, students, and alumni.
- Accessing only that information which you are authorised to access
in the course of your duties. Your ability to access other
information does not imply any right to view, change, or share
information.
- Not establishing access privileges for yourself or others outside of
formal approval processes.
15

PwC
- Adhering to procedures and business rules governing access and
changes to the data for which you are a custodian.
- Expect all stewards and custodians of administrative data to
manage, access, and utilise this data in a manner that is consistent
with the need for security and confidentiality.
• Correlation between physical and network security.

Implementing a pro-active strategy in your
organisation
17
September 2011

PwC
organisation
• Cyber security is just as important as physical security.
• Relationship between physical and network security.
• Know and understand your organisation:
• This includes an understanding of the external environment and
the threats facing the organisation. It also refers to a thorough
understanding of the internal environment and the way the
organisation operates – its employees, levels of staff morale,
business partners of the organisation, service providers, etc.
18

PwC
organisation
• Define security roles and responsibilities:
• Although security should be everyone within an organisation’s
concern, ownership of information security should be assigned to
specific individuals, coupled with the necessary levels of authority
and accountability. To assist with the process it is recommended
that security roles and responsibilities be incorporated into job
descriptions and that performance in terms of these areas be
measured accordingly.
• Ensure that you have proper policies and procedures in place for the
use of IT.
• Establish clear processes to enable end-users to report suspected
cyber crimes.
19

PwC
organisation
• Effective public private partnerships.
• Value of intelligence: Exchange information with law enforcement
agencies and other organisations. Know your opponent and use the
information to develop and update security policies. Think like a
hacker.
20

PwC
organisation
• Stay up to date:
• Maintain awareness of new developments in both technology and
services. Use a risk-based approach to determine when it would
be necessary to upgrade or adapt current systems and processes to
accommodate new developments.
• Continuous auditing and assessment of process:
• It is recommended that a process of continuous auditing be
implemented to ensure that the strategy remains aligned to
business objectives, adapts to changes in technology or identified
threats, and to allow for the analysis of information that is
gathered from the different implemented controls.

PwC
“The vast majority of computer breaches that we have investigated
over the past few years have been the result of poor personal choices,
weak computer practices, and less-than-satisfactory data-handling
procedures.”
Steve Shuster, director of IT Security at Cornell

September 2011

PwC
• Email is more than messages. It contains personal information,
contact lists, sensitive company information, etc. Email policies:
• Do not open suspicious emails.
• Use spam filters.
• Encrypt important files or records.
• Choose complex passwords and change your password regularly.
The Post-it problem.
• Back up regularly.
• Install powerful anti-virus and firewall software and keep it up to
date. Regularly update security patches.
23

PwC
• Create good habits such as deleting your temporary internet files
and cookies. This protects against hackers who can access your
accounts from where you have been on the internet.
• Turn off your computer and modem/disconnect from the internet
when not in use.
• Know what information you have, where it is stored and who has
access thereto.
• Be wary to provide personal information via a website you are not
familiar with.
• Never allow strange or unfamiliar individuals to use your computer,
not even if they say they are from the IT department!
24

PwC
• Where practicable, do not grant administrative or root/super user
privileges to end-users.
• Educate users:
• Teach IT users how to identify cyber threats and how to respond.
• Share security information with all users of IT in the organisation.
• Read up on the latest ways hackers create phishing scams to gain
access to your personal information.
25

PwC
• Campus executives and data stewards should know:
- What/where is my data?
- How sensitive is it?
- Who is responsible for it?
- Who has access to it?
- Do I need to keep it?
- What if it gets into the wrong hands?
26

PwC
Closing remarks
• Need to realise the true value of information.
• Cyber criminals steal INFORMATION.
• We can only effectively combat cyber crime if we share information
and collaborate.
• Know your opponent.
• Be pro-active and not re-active.
• Implement good information governance principles in your
organisation.
• Educate all IT users.
• Protect your information with the same vigour as you protect
physical property, brand names, money, etc!
27

“It takes more than anti-virus software to
safeguard your computing resources and data. It
takes you. Taking steps to secure your computer
not only helps keep your data safe, it
demonstrates your commitment to protecting the
university network and all data created, stored,
and shared over the network by the campus
community.”
