Lecture 40
Social Implications of Computing
2
Focus of the last Lecture was on
Cyber Crime
• We found out about several types of
computer crimes that occur over cyber space
• We familiarized ourselves with with several
methods that can be used to minimize the ill
effects of these crimes
3
Three Phases of the DoS
1. Search
2. Arm
3. Attack
4
Neutralizing the Attack
• The engineers responsible for monitoring the
traffic on the Yahoo Web sites quickly identified
the key characteristics of the packets
originating from those drones
• Then they setup filters that blocked all those
packets
5
How to stop DoS attacks from taking place?
• Design SW that monitors incoming packets,
and on noticing a sudden increase in the
number of similar packets, blocks them
• Convince system administrators all over the
world to secure their servers in such a way that
they cannot be used as drones
6
Cyber crime can be used to …
• Damage a home computer
• Bring down a business
• Weaken the telecom, financial, or
even defense-related systems of
a country
7
Mail Bombing
• A stream of large-sized eMails are sent to an
address, overloading the destination account
• This can potentially shut-down a poorly-
designed eMail system or tie up the telecom
channel for long periods
• Defense: eMail filtering
8
Break-Ins
• Hackers are always trying to break-in into
Internet-connected computers to steal info or
plant malicious programs
• Defense:
– Firewalls
– Intrusion detectors
– Other effective security policies
9
Credit Card Fraud
• A thief somehow breaks into an eCommerce
server and gets hold of credit numbers and
related info
• The thief then uses that info to order stuff on
the Internet
• Alternatively, the thief may auction the credit
card info on certain Web sites setup just for that
purpose
• Defense: Use single-use credit card numbers
for your Internet transactions
10
Software Piracy
• Using a piece of SW without the author’s
permission or employing it for uses not allowed
by the author is SW piracy
• Defense: Various authentication schemes.
They, however, are seldom used as they
generally annoy the genuine users
11
Industrial Espionage
• Spies of one business monitoring the network
traffic of their competitors
• They are generally looking for info for future
products, marketing strategies, and even
financial info
• Defense: Private networks, encryption, network
sniffers
12
Web Store Spoofing
• A fake Web store (e.g. an online bookstore) is
built
• Customer somehow find that Web site and
place their orders, giving away their credit card
info in the process
13
Viruses (1)
• Self-replicating SW that eludes detection and is
designed to attach itself to other files
• Infects files on a computers through:
– Floppy disks, CD-ROMs, or other storage media
– The Internet or other networks
14
Anatomy of a Virus
A virus consists of 2 parts:
• Transmission mechanism
• Payload
15
Other Virus-Like Programs
• There are other computer programs that are
similar to viruses in some ways but different in
some others
• Three types:
– Trojan horses
– Logic- & time-bombs
– Worms
16
Today’s Goals:
(Social Implications of Computing)
We will try to understand the impact of
computing on:
– Business
– Work
– Living
– Health
– Education
17
Introduction
• It should be clear to you that - for better or
worse - the future of computing and the future
of humankind are highly interdependent
• Computers have solved many problems for the
humankind but have created a few tricky ones
as well
• Today we will discuss both, but first …
• Why is it important to discuss the social
implication of computing?
18
Why should we, as computing
professionals, be interested in studying
the social implications of our creations?
• Computing technology has changed our way of
life like no other technology
• We need to study how it has done it to highlight
the mistakes and success stories of the past
• We need to do it so that we can learn from
them and select our future direction accordingly
19
Let’s Start with the Dilemma of Computing
• Computers keep on becoming more and more
powerful and gaining more and more autonomy
• They are being equipped with fail-safe and self-
healing technologies
• Are we heading towards a future where the role
of the masters and the slaves will be switched?
• Should we slow down or even reverse some of
the technology advances to avoid that dark
scenario?
20
Let’s now look at how computing has impacted
the field of
Business
21
Powerful Global Corporations
• Internet-based communication is allowing
business entities to coordinate the activities of
their globally-spread units with greater
accuracy
• The knowledge gained by one unit becomes
available to all others very quickly
• All this has made these business entities very
powerful, even more powerful than many
22
The Network Organization (1)
• The network paradigm (all connected to many
others) is becoming the preferred
organizational structure of more and more
organizations as time goes by
• This new organization is replacing the old-style
layered, tree-structured organizational model
23
The Network Organization (2)
• The organizations are learning that business
can be done in a more effective manner if
emphasis is placed upon cooperation, shared
responsibility and networking:
– Within the organization
– And also with their customers and suppliers
• The structure of the networked organization is
flexible (although, at times a bit chaotic!), and
changes according to the demand of the times
24
The Networked Organization (3)
• It shares knowledge and decentralizes the
control of the operation so that network works
effectively to meet the business goals of the
organization
• The workers :
– Can spend more time doing creative work as they
have immediate access to all of the required info
through various computer-based technologies
– Have a sense of ownership in the organization
25
While old professions are being eliminated …
• Typists
• Bank tellers
• Telephone operators
26
… new types of jobs are being created
• CIO
• CKO
• CSO
27
Number of Temporary Workers is on the Rise(1)
• Even technical professionals of high-quality
must now define themselves as temporary
consultants, able to move from project to
project within in an organization as well as
among different organizations
28
Number of Temporary Workers is on the Rise(2)
• In the old days, loyalty was important, now
professionalism and ability to perform are the
watch words!
• The focus now in many computer-centric
organizations is not belonging to the
organization, but on professional competency
and quality of work
29
Businesses Monitoring Their Employees
• Systems are available that monitor almost
every key stroke that an employee makes on a
computer
• Systems are available that read and censor all
incoming and outgoing eMail
• It is quite straight forward to monitor where you
surf, and when
30
Working from Home
• Computing has made it possible for some to
avoid going the office for their work
• They can do their work from home and
communicate their ideas, questions, answers to
their colleagues through the Internet
• This gives them more time to spend with their
families due to the time they save on
commuting to their place of work
31
Working from Home: Disadvantages
• Contact with the colleagues and the quality of
communication is reduced, which may result in
a poorer quality of work
• Lack of interaction may also result in slower
professional growth
• Family life may suffer as well, as some never
turn off, and keep on working through out the
day, evening and night!
32
From Mass- to Personalized-Marketing(1)
• In the old days demographical data was
analyzed and mass-marketing campaigns were
launched to influence a reasonable portion of
the population
• The Web has changed marketing forever,
redirecting it from a mass focus to a single-
person focus
33
From Mass- to Personalized-Marketing(2)
• Our Web surfing data are captured. We are
asked questions about our lifestyle in return of
randomly awarded prizes
• All the collected data is then analyzed to
determine patterns in our behavior, and
individualized offers for services and goods are
displayed in front of us on the Web or eMail
34
Politics
35
The Political Process
• We no longer need to gather the public’s
opinion through expensive referenda or public
meetings
• Through computer discussion forums,
newsgroups and mailing-lists, public and
politicians may engage in a free, open
exchange of ideas without leaving the comfort
of their not-so-comfortable and very
comfortable homes, respectively
36
Social
Aspects
37
Distances Have Contracted
• Because of the ever-decreasing costs of verbal,
text, video communications, it is becoming
easier to stay in touch of anyone, regardless of
their physical location
• This has had a profound effect on small
businesses, especially in developing countries
like Pakistan
• It has also made it possible for families and
friends to become closer in spite of the physical
distance between them
38
Distances Are Increasing
• Television was bad enough; Video games and
the Web has made the situation even worse
• Families are spending less & less time together
in spite of the physical closeness. This may
have a very detrimental effect on the emotional
well-being of the children, … and parents
• Solitude is the order of the day as many
children & adults spend their free time surfing,
chatting, playing computer games, instead of
spending it on interacting with friends or family
39
Virtual Communities (1)
• Interest-based, instead of geography-based
communities
• Ex: Ta’suv’voof, tennis, telepathy, cancer
• Members with common interest share ideas,
ask questions, post answers and make
announcements through mailing-lists, news
groups or message boards
40
Virtual Communities (2)
• These communities are definitely very different
from traditional ones
• There are generally no bars on membership
based on gender, race or religion
• However, they may lack the respect for the
individual and civility that are the norm within
conventional, geography-based communities
41
A Society Under Surveillance
• While surfing, we are being watched, constantly
• Our every click is recorded and analyzed to
extract patterns and behaviors
• Those patterns are then used to persuade us to
do things that those Web sites want us to do
• Webcams are becoming common. Providing a
cheap way for parents to watch their children's
every move
42
Education
43
The Changing Face of Education (1)
• Distance learning has received a boost due to
the low-price of Internet communication and the
availability of Web-based interactive content
• It has also become possible for students to
interact in real-time with other students as well
as teachers located a long distance from them
• Physical location is less of a hindrance now
44
The Changing Face of Education (2)
• Students enrolled in distance-education
programs have more control over what they
want to learn, how they want to learn, and when
• The lack of face-to-face interaction and
immediate to-and-fro questions and answers
may, however, reduce the amount of
knowledge that can be transferred from the
teacher to the student
45
The Changing Face of Education (3)
• In spite of that problem, computer-based
distance education may be the only source of
high-quality education for many, especially
those in remote locations
• The fact, however, remains that the best mode
of education is the conventional one, which has
become more effective with the augmentation
of computer-based learning aids
46
Info Gathering
• We are turning more and more towards online
resources of info
• The info that just a few years back involved
effort and time to pull together before it could
be used is now literally a few key strokes away
• The time and effort spent on gathering info can
now be spent on using it
• This capability has made the computer an
active (and integral) part of our creative
47
Health
48
Telemedicine (1)
• How can we place a doctor specializing in, for
example, skin-related diseases or neurology in
every district’s hospital?
• We cannot! What then? Ignore all those not
residing in big cities?
• Solution: Internet-based telemedicine
49
Telemedicine (2)
• An audio/video/text connection combined with a
few remote medical instruments and a trained
assistant can enable a remote doctor to
examine and prescribe medicine to a patient
far, far away
50
Is Progress Necessary? (1)
• Progress is being made every day in the field of
computing. The question that we need to ask
is: “Are we going in the right direction?”
• Is it OK to make available all sorts of info to
everyone? Does everyone needs to know how
to build an H-bomb?
51
Is Progress Necessary? (2)
• Is it OK to keep on investing in surveillance
technologies? Do personal privacy have no
place in our technologically advanced future?
• Is it OK to automate everything that we lay our
eyes on? Or certain things (e.g. caring for an
infant) should remain with us old-fashioned
human beings
52
Closure
• Your answers to the questions that I just raised
may differ from mine, and I respect your
opinion
• All I say is, yes, progress is inventible, however,
you – the creators of my future – should be a
bit thoughtful about what you do
• I command you to “go and invent the future,” it
is your duty and you may not desist from it, but,
please, do think about the social implications
and consequences of what you are doing
53
