Simplifying Security.

Our View: Bolstering Internet Security Is Imperative
On Monday, the Obama administration proposed a much‐needed international effort to bolster the security of the Internet. It’s
needed because cyberspace has come to serve as both a communications miracle and, potentially, one of the greatest threats to
our security in the 21st century.
That description may seem like hyperbole as it pulls in two completely different directions. But there are justifications for both
descriptions.
The Internet is arguably the greatest technological breakthrough introduced to our society since the television. Perhaps that’s more
hyperbole, unless you consider just how much of our world now is tied to online access and interconnectivity.
The 2010 census noted that 68.7 percent of all U.S. households have Internet connections; a vast majority of businesses also use
the Web for marketing or for inventory purposes, among other tools.
Cyberspace has become a staple in our lives, even if you don’t have an Internet connection in your home or office. Our banking, our
medical records, our credit and our businesses are all linked in some form to the Web. So, too, is much of our infrastructure, our
communication and our national security. Odds are, there is something you want, rely on or need each day that is dependent on
Internet connectivity for you to have it. That may not be a game‐changer in terms of how you live your life, but it’s definitely a
sobering impact.

Instant Messaging Security Issues
31
IMWorm
 A worm that harms the computer and locates all the
contacts in the IM address book
 The IMWorm tries to send itself to all the contacts in the
user’s IM contact list
Social Engineering
 Social engineering depends on human interaction that
involves tricking people through IM and getting their
personal information
Spam over IM( SPIM)
 SPIM is spam delivered through IM instead of delivering
it through email
 IM systems such as Yahoo! Messenger, AIM, Windows
Live Messenger, and chat rooms in social networking
sites are popular targets for spammers

Instant Messaging Security Measures
32
Do not reveal personal information
on IMs
Do not accept links received from
unknown people on IM
Block the users who send unsolicited
web‐links
Always use strong passwords
Sign out of the IM application after
using it
Do not check the Remember
password option

Searching on the Web
33
Search engines display
hundreds of results for a
search query
Not all the web page results
obtained by the search
engine are secure

Online Gaming and MMORPG
35
It has also become the target
for attackers for the large
amounts of money involved
Online gaming has become a
popular pastime, especially due
to high‐speed Internet and
emerging technology
In the world of MMORPGs, also known
as online games, players can meet other
players, become friends, engage in a
battle, fight against evil, and play
MMORPGs are popular
worldwide and the revenues
for these games are well
over a billion dollars
Massively Multiplayer Online Role‐
Playing Game (MMORPG) is a type
of computer role‐playing games in
which a large number
of players interact with one another
within a virtual game world

Online Gaming Risks
36
Interactions with
potential fraudsters who
may trick the gamer to
reveal personal/financial
information
Computer intruders
exploiting security
vulnerabilities
Online and real‐world
predators
Malware such as viruses,
Trojan horses (Trojans),
computer worms, and
spyware

Insecure or Compromised Game Servers
and Game Coding
If the software at the game server is compromised,
the computers that are connected to the server can
also be compromised
Any game with a network connection has a risk
involved
The attacker may even use the vulnerabilities to
crash the gaming server
The vulnerabilities in the game server can be used by the
attackers to:
 Steal game passwords
 Steal information from the gamers’ computers
 Control the gamers’ computers remotely
 Launch attacks on other computers
 Install programs such as Trojans, adware, spyware
The game code is generally not as well analyzed as the
other software coding
This may result in introducing unknown vulnerabilities
onto the computer

Social Engineering
Identity Theft
Protection Schemes
Cyber Prostitution
Social Risks
The attackers may use the social interaction in the online game environment to
attack the unprotected computers or to exploit security vulnerabilities

Note: Game Masters (GMs) of a game will never ask a gamer for his/her username and/or password
Social Engineering
Attackers may trick the gamers into installing malicious
software on their computers by social engineering
They offer a bonus or help in the game in exchange for
other players’ passwords or other information in the
game forums on a game server
The gamers who are looking for ways to make the play
easier respond to such offers
Attackers send phishing emails supposedly from
the game server administrators, which will invite the
player to authenticate his/her account via a website
linked in the message

Protection Schemes, Cyber Prostitution,
andVirtual Mugging
41
Organized crime has
emerged in South Korean
gaming community
The criminal organizations
force the gamers into
protection schemes,
where the gamers have to
pay money (virtual or
real) to avoid killing of the
gamers’ characters and
theft of the passwords
Online games are being
used for cyber prostitution
where the
customers/gamers pay
money for cybersex
In The Sims online, a
Massively Multiplayer
Online (MMO) game, a 17‐
year‐old developed a cyber
“brothel”, where the
gamers paid Sim‐money
(Simoleans) for cybersex
per minute
The gamers’ accounts were
eventually cancelled
Virtual mugging was
coined when some
players of Lineage II
used bots to defeat
other gamers and take
their items; these items
were later put on sale in
online auctions

How the Malicious Users Make Money
Stolen items such as passwords or virtual items are put on sale on websites, such as eBay, or on forums
These are sold to other gamers for real or virtual money
The cyber criminal may ask the gamer for ransom in return for this information

Security Practices Specific
to Gaming
43

Recognize Administrator Mode Risks
1 2
44
Some games require the
game to be run in
Administrator mode
 If that is the case, ensure
that the game has been
downloaded from a
trusted website/vendor
Free downloads of games may
contain malicious software,
including plugins to run the
game
 This software may be used
to gain administrator level
control of the computer
Instead of using the
administrator account, the
gamer is advised to browse the
Internet or play the games
using a User Account, which
may deny the attacker access
to administrator rights
3

Recognize Risks due to ActiveX
and JavaScript
45
Some of the games played
over the web require
ActiveX or JavaScript to be
enabled

Play the Game, Only at the
Game Site
46
Play the games at the
game site and save
the Internet
browsing for later
Once done with
playing the game,
switch to the user
account to browse
the Internet
This reduces the risk
of visiting a malicious
website when playing
a game

Pay Attention to Firewall
Management
Playing certain multiplayer games may require the
firewall settings to be changed to allow information
from the game to get through to the gamers’ computers
Every time the permissive settings are changed
on the firewall, the risk of computer security
concerns increases
In the firewalls, the gamer can designate the fellow
gamers’ IP addresses as trusted to avoid any interactions
with the attacker

Risks Involved Online
49
The risks involved when a child works
online include:
Misdirected searches
Stealth sites and misleading URLs
Online sexual harassment
 Child pornography
 Grooming
 Cyberbullying

Misdirected Searches
Parents may take all the precautions to protect the child online, but all that could
be negated when the child is unconsciously led to visit harmful sites
Search engines use terms known as “meta variables” to index a website
When a user searches for websites, the search engines display the results using
the meta variables
Porn site promoters add popular search terms to their meta variable list, to redirect
the web traffic towards their site
Porn sites may use the words “sports”, “school”, “movies”, etc., to lure children
to their websites
Unless a filtering software is used, the search engines cannot distinguish between
the search requests of an adult and a child
50

Example: a sports website may be indexed by the meta terms “soccer”,
“football”, “scores”, etc.

Stealth Sites and Misleading
URLs
51
Pornographic websites
thrive on increased web
traffic
Pornographic sites use
common typo errors to
lure visitors to their
websites
Children may end up at a
pornographic website just by
typing
“www.whitehouse.com”
instead of
“www.whitehouse.gov”
Porn site promoters buy
domain names such as the
“.com” equivalent of a “.gov”
or a “.org” website, being
aware that web surfers would
end up at their website if
there is a typographical error

Child Pornography, Grooming, and
Cyberbullying
Child Pornography Grooming Cyberbullying
52
“Under federal law (18 U.S.C.
§2256), child pornography is
defined as any visual depiction,
including any photograph, film,
video, picture, or computer or
computer‐generated image or
picture, whether made or
produced by electronic,
mechanical, or other means, of
sexually explicit conduct, where
the production of the visual
depiction involves the use of a
minor engaging in sexually
explicit conduct”
“Grooming” is an act of
befriending and establishing
emotional connection with
children
Child grooming is used for
lessening the child’s
inhibitions and preparing
them for child abuse
The offenders target children
through attention, affection,
kindness and sympathy, and
offer gifts and/or money
Cyberbullying occurs when a
child, preteen or teen, is
threatened, harassed, and/or
embarrassed using the
Internet or mobile phones or
other communication media
Cyberbullying signs:
 Upset after using the
computer
 Refuse to step out of the
house or to go to school
 Draws away from friends
and family

Role of the Internet in Child Pornography
The Internet provides easy access to huge quantities of pornographic materials
Various web services such as emails, newsgroups, and chat rooms facilitate the
sharing of pornographic materials
It supports transfer of pornographic materials in various formats that can be
stored on different digital storage devices
It provides a cost‐effective medium for the transfer of pornographic
materials
It enables people with an Internet connection to access pornographic
materials at any time and anywhere
It ensures complete anonymity and privacy
53

Effects of Pornography on Children
54
Child victims suffer
from depression, anger,
withdrawal, and other
psychological problems
Physical injuries due to
molestation, such as
genital bruising or
exposure to sexually
transmitted diseases
They experience mental
weakness such as:
 Guilt and feeling
responsible for the
abuse and betrayal
 A sense of
powerlessness and
worthlessness
 Low self‐esteem

Risks Involved in Social Networking
Websites
People on the social networking websites can view the profiles,
photos, and videos of other people on that website
The child may provide too much information on a social
networking website
Online predators may get information such as email IDs,
telephone numbers, residential address, hobbies, interests
and more from their profile
Online predators may use this information for cyberbullying,
identity theft, or cyber exploitation
55

Unsolicited Emails
56
Online predators may
use email techniques
to steal information
from children
They may send spam emails
that contain pornographic
materials or links to
pornographic websites
The child may even be
asked to register on that
website by providing
personal information

57
Chat Rooms
Online predators may use
social engineering techniques
to get personal information
from children in a chat room
Online predators may use chat
rooms to build contacts with
children and then lead them into
cyber prostitution
They may also use chat rooms
to sends links to websites with
inappropriate content, such as
pornography
They may also send malicious
links to children, which may
result in the computer getting
infected with malware

Finding if Children are at Risk Online
The parent can find if their children are facing any online threats from the following symptoms:
The child spends more time sitting at the computer
Pornographic material is present on the child’s computer
The child receives phone calls and/or gifts from unknown
persons
The child turns off the monitor or quickly changes the
screen when the parent enters their room
The child looks depressed and does not show any interest in
talking with family or friends
58

Protecting Children from Online
Threats
59
Ensure that the child knows about dangers
of computer‐sex offenders
Monitor what the child does on the
computer
Use caller ID on phones to determine who is
calling the child, and block numbers that
are suspicious
Monitor the child's access to all types of live
electronic communications such as chat
rooms, instant messages, Internet Relay
Chat, etc.
Restrict access to the malicious and porn
websites using Internet content filtering
software
If the child is maintaining a social
networking profile, look closely at what
information they have posted in their
member profiles and blogs, including
photos and videos
Check credit card statements each
month for any unusual charges that may
indicate unauthorized purchases by a
stranger or your child
Notify the police if someone the child
met online starts calling them, sends
gifts, or trying to lure them for revealing
sensitive information
Ensure that the child does not:
 Provide personal information such as
name, address, phone, school name
 Meet anyone online without
permission
 Open emails from unknown senders
 Share their photos/videos with
strangers over the Internet

The parents should encourage their children to
report any inappropriate behavior they may face
online
The parents can encourage the child to come to
them if they are being bullied or are facing online
predators
The children may also be encouraged to speak to a
trusted individual such as an aunt, uncle, or older
sibling, if they are uncomfortable talking to the
parents
Encourage Children to Report
