1Welcome to Internet Guard Dog
Using Internet Guard Dog
In the last fewyearsthe Internet has changedfrom acommunications network
that government entities and universities used almost exclusively, to an
information treasure house that people of all ages and occupations can now
access. With an Internet account, youcan send electronic mail (e-mail) around
the world in seconds, do research without leaving home, meet new friends in
an onlinechat room, or shop without getting out of your bathrobe. However,
with all these conveniences come a certain element of risk. When you use the
Internet, information istransmitted fromyourcomputer toother computers in
the Internet—information you may not want other people to have. And those
computers can also send files to your computer that may contain viruses.
While most of these files are harmless, some can invade your privacy or even
damage the data on your computer’s hard drive.
Figure 1-1. Internet Guard Dog Home screen
™
1
McAfee’s Internet Guard Dog addresses any of these potential risks with its
comprehensive features designed to protect your privacy and security when
surfing the Internet.
User’s Guide 1
Welcome to Internet Guard Dog™
With its new features, you can now also act as an Administrator and apply
customized protection settings not only for yourself, but for other users of
your computer and easily monitor potential risk they may encounter while
browsing the Internet.
How Internet Guard Dog works
Internet Guard Dog works via the following main features displayed in the
Home screen:
User Setup
As the Administrator, this feature allows you to setup protection settings for
other users of your computer. Y ou can add, edit and delete a user’s
profile—then setup individual privacy, security and Internet filtering options
that Internet Guard Dogwill apply w henever any of these users are browsing
the Web through your computer.
See the following for more information:
• “Customize User Setup Settings” on page 33.
• Chapter 4, “Privacy Features.”
• Chapter 5, “Security Features.”
VirusScan
Internet Guard Dog now uses the McAfee VirusScan to address virus-related
problems you may encounter through the Internet. This feature allows you to
set how to perform a virus scan operation on your computer; what to do if a
virus isfound; and how it should alert you once thevirus is detected. You can
also direct VirusScan to keep a recordof actions performedon yourcomputer.
With these mainfeatures of InternetGuard Dog, youarein controlat all times.
You decide what security and privacy features to use. If your concerns or
computing habits change, it is easy to change Internet Guard Dog protection
settings to meet your needs and those of others who use your computer
frequently. See “What is McAfee VirusScan?” on page 49.
Activity Logs
On the Internet Guard Dog Home screen, Activity Logs allow you to view a
list of all the interactions that you and other profiled users of your computer
had with Internet Guard Dog, including the date and time of the action. You
can print, save or clear this list. See “Viewing Activity Logs” on page 23.
2 Internet Guard Dog
Welcome to Internet Guard Dog™
Security Check
You can run a complete check of your computer for any privacy or security
problems via this feature. After Internet Guard Dog performs the check, it
displays any problem found, provides additional information about the
problem, and guides you through on how to solve the problem. See
“Performing a Security Check” on page 25.
Internet Guard Dog and your online connection
To use all Internet Guard Dog features, you must have an Internet connection
through a local network or a modem. Some networks have an Internet
connection that you can use by connecting to the network-either directly or
through dial-up networking. If you don’t connect through a network, your
computer must have a modem installed.
You can establish anInternet connectionthrough anInternet Service Provider
(ISP) such as Earthlink. An ISP acts as a middleman between you and the
Internet. Your computer connects (using your modem) to the ISP’s equipment,
which in turn connects to the Internet. You may also be connected to the
Internet through an online service such as America Online or Compuserve.
In addition, you must also have a browser. A browser is software, such as
Netscape Navigator or Microsoft Internet Explorer (it must be a version
designed for Windows 95 or Windows 98), that allows you to view text and
graphics and download files from Web sites.
Internet Guard Dog features
This section brieflydescribes other featuresof Internet GuardDog that protect
you from the most common Internet threats. If you want more background
information on Internet privacy, security, and virus issues, see “Internet
Security and Privacy” on page 55.
NOTE: Only the designated Admi nistrator or Self-Administrator can
have access to these features which allow them to customize protection
settings for themselves and in the case of the Administrator, protection
forotherprofiledusersofthesamecomputer.
User’s Guide 3
Welcome to Internet Guard Dog™
Protection from privacy threats
• Identity Protector monitors your Internet connection and warns you
before private information is sent to an unsecure Internet site. It stops
programs and other people that use your computer (like your kids) from
sendingyour name and credit cardnumbers overthe Internetwithout your
approval.
• Cookie Blocker prevents Web sites from storing cookies on your hard
drive. Third-party Web sites use cookies to track your Web browsing
habits. You can choose your level of interaction with Cookie Blocker. (For
more information, see “What are cookies and how are they used?” on
page 65.)
• Web Trail Cleaner cleans yourWeb browsing trailssuch as cachedfiles; list
ofURLs (Uniform ResourceLocator,also known as Webaddress)visited; and
history files—when you close your browser. This feature prevents other
users of your computer to track your online movements by viewing the
files and URL addresses l eft over from your Internet browsing.
• Search Filterprevents search information that you request at one Web site
from being passed along to the next site you visit. Without Search Filter,
your browser can transfer your search request information from one Web
site to another without your knowledge.
Protection from security threats
• Gatekeeper allows you to control the programs that have access to your
Internet connection. Programs on your PC can be programmed to access to
the Internet without your consent.
• File Guardian protects files that contain your sensitive data from being
opened, renamed, copied, moved, or deleted. Programs, such as ActiveX
and Java programs, can scan your PC for personal information or delete
files without your permission.
File Guardian also limits access to protected files either to programs you
specify or through file encryption. It can limitthe programs that can access
your tax, on-line banking, or personal accounting data files.
• Password Manager stores your Web site login names and passwords for
protected Web sitesin one securelocation. When you are visitinga site that
requires this information, drag it from Browser Buddy to the form
displayed in your browser. No more storing your login names and
passwords in an unsecure location, such as post-it notes on your monitor
or in a text file on your Windows desktop.
4 Internet Guard Dog
Protection from virus threats
Using the McAfee VirusScan, the following features are available:
• Scan to start the default virus scan task immediately, or config ure a virus
scan task that suits your needs.
• Scheduler to launch the McAfee VirusScan Scheduler. This utility enables
you to configure and run unattended virus scan operations.
• Virus info to display virus information via the McAfee Web site.
What’s new in Internet Guard Dog
Internet Guard Dog version 3.0 includes these new features.
• Inclusion of McAfee VirusScan
McAfee VirusScan is now included in Internet Guard Dog. Select from
availableoptions to customized how you want itto protectyour computer.
• Multi-user Logon and user settings
Internet Guard Dog now allows multiple users to have different
protections settings. The main user can also act as an Administrator
customizing settings for other users of the same computer.
Welcome to Internet Guard Dog™
• Internet Filtering options
After an Administrator has added profiles of other users of the computer,
Internet Filtering optionscan be usedbased ondefault URL sites,word list,
rating systems, and Internet access time. Administrator can also enter
additional lists or sites if desired.
• Activity Logs
An Administrator can view a list of activity, maintenance and violation
logs at the single click of a button. This list contains information such as
duration of computer use or any protection setting violation that a profiled
user may have committed (e.g., attem pting to pass credit card number).
Administrator also has the option to clean, print or save this list.
• Improved online Help interface
The online Help is now displayed via a tri-pane Explorer View Help
window. While viewing a topic within the Help file, the user can now also
view the table of contents as well as access the index and full-text search
options simultaneously while the topic is displayed on the right-hand side
of the window.
User’s Guide 5
Welcome to Internet Guard Dog™

viewed or changed. It also prevents other users of your computer from
sending out information that you specify as private.

Protects individual files even when encrypted.
• Improved cookie management

without your OK.

being read—until you decode them.

can effectively use its feature to protect you from Internet threats.
™
Using the Internet Guard DogInterview
Although Internet Guard Dog is set up to use security and privacy settings
that are appropriate for most users, some features require your input. The
Interview provides an easy means of customizing your Internet Guard Dog
settings.
Eachinterview screen eithertells you abouta Internet Guard Dogfeature, asks
you to enter information, or asks you how you want Internet Guard Dog to
respond to certain situations. (Figure 3-1.)

What information does Internet Guard Dog ask me to enter?
The Internet Guard Dog interview asks you to enter the personal andfinancial
information that you want to protect. All the information you enter into
Internet Guard Dog is stored in encrypted form on your hard disk— it is never
sent to McAfee Software.
You may want to gather your personal information before you start the
interview. During the interview, Internet Guard Dog allows you to enter:
• A password that you can use to protect your Internet Guard Dog
information.
• Personal and financial information that you want to protect from being
sent out over the Internet without your knowledge:
•Name
• Address
• Social Security number
• Telephone number
• E-mail address
• Other financial numbers such as bank account, brokerage account,
credit card, phone card, and so on.
• Any Web site login names and passwords that you want to store in
Password Manager.
• Information about other users of your computer. If you are the
Administrator, you can create user profiles and set protection settings that
Internet Guard will use whenever the user is browsing the Internet via
your computer. See “How Internet Guard Dog Administrator works” on
page 17.
For optimal protection by Identity Protector, include all dashes (such as Social
Security number, bank account numbers, brokerage accounts, and ATM
cards). For example, if you enter 123-45-6789 as your social security number,
Guard Dog will recognize the number with or without the dashes. If you enter
123456789, Guard Dog won’t alert you if the number is sent out with dashes
(123-45-6789). Credit cards do not need dashes because you type the numbers
into separate boxes.

How Internet Guard Dog Administrator works
Since Internet GuardDog nowoffers multi-userlogon capabilities,this feature
allows one userto act as the administratorof personal information, protection
and security settings entered via the Internet Guard Dog features. This is
particularly useful if for example, you would want to filter, block or monitor
certaintypes of informationthat you donot want your children toaccesswhen
browsing the Internet.
Creating an Internet Guard Dog Administrator account can only be done in
the Interview feature of Internet Guard Dog. And only the designated
Administrator can access and change information and protection settings of
the computer.
After this setup is complete, the Administrator can add other users and set the
levels of security and protection for each user profile.

What Cookie Blocker does
Cookies are smallfiles that your Web browserstores onyour PC at the request
of a Web server. Each time you view a Web page from the Web server, your
browser sends the cookie back to the server. These cookies can act like a tag,
which lets the Web server track what pages you view and how often you
return to them. Some Web sites, such as Microsoft Expedia
store your password and preferences so that you can automatically log on to
the site. For a more detailed description of cookies, see “What are cookies and
how are they used?” on page 65.
Internet Guard Dog’s Cookie Blocker offers three options for controlling the
use of cookies on your computer. Internet Guard Dog can:
• Reject all cookies.
• Accept all cookies.

• Display an alert message each time a cookie is sent to your browser. The
alert displays the name of the entity trying to set the cookie, and provides
you the option either to acceptthe cookie or not.
When setting up Cookie Blocker in Protection Settings, you can select one
optionfor direct sitesand another forindirectsites.Direct sites are those that
you deliberately access. For example: typing the URL address in the
location bar of your Web browser; clicking a link in a Web page; or
selecting from your list of bookmarks or favorite sites. Indirect sites are
those that you access because the site you are connecting to directly
displays content from another site as part of its own content. For example,
if you went directly to Cool_site.com, it could display an ad from
Ads-r-us.com (the indirect site) in a separate frame in the Cool_site page.
If during the Interview, you accepted Internet Guard Dog’s
recommendation on how to respond to cookies, Cookie blocker will:
• Automatically allow cookies to be accepted from direct sites.
• Display an alert message when an indirect sites tries to set a cookie.

What Identity Protector does
It is easy to forget that when you sendinformation over the Internet, it doesn’t
go directly from your computer to the computer that is storing the Web page
information. Instead, the information can pass through many computers
before it reaches its final destination.
Identity Protector can keep your software from sending any personal
information over the Internet to an unsecure site. Although you don’t have to
worry about a sitewhen itusing asecure connection, there are many Web sites
that use a secure connection only when dealing with credit card transactions.
(For more information, see “Privacy on the Web” on page 58.)
User’s Guide 33
Privacy Features
If more than one person is using your computer, make sure that you create an
Internet Guard Dog password. If the person using your computer doesn’t
enter the Internet Guard Dog password, it automatically replaces any
protected personal information sent to an unsecure site with the text, “xxxx.”
For example, if your child tries to order the latest CD without entering your
Internet Guard Dog password, it replacesyour credit card number with “xxxx
xxxx xxxx xxxx.”
Identity Protector offers three optional responses whenever an application
tries to send out information over the Internet to an unsecure site:
• Let the information go out.
• Block the information from going out.
• Display an alert message when any application tries to send the
information over the Internet to an unsecure site. This is the response that
Internet Guard Dog sets up when you add information to protect in the
Internet Guard Dog Interview.
Responding to an Identity Protector alert message
During the Interview, Internet Guard Dog asked you to enter your personal
and financial information that you want to protect. Internet Guard Dog
displays the Identity Protector alert message the first time an application tries
to send out this information to an unsecure site.

What Gatekeeper does
Gatekeeper lets you control what programs on your PC can have access to
your Internet connection. Gatekeeper can also warn you about any of these
potentially harmful actions:
• Your browser is directed to a harmful site—one that has been known to
contain virus-infected files (e.g., Trojan horses, prank or destructive
ActiveX controls, or other security concerns).
• A program silently uses your modem to connect to another computer.
• A program starts up another program.
• A program sends out over the Internet a number that follows a common
credit card number pattern.

starting another program, and programs sending out credit card-like
numbers.
Internet access alert message
Each time you start a program that attempts to use your Internet connection,
Internet Guard Dog checksto see if that program is in the list of programs
allowed to access the Internet. If the program is not in the list, Internet Guard
Dog displays an alert message to tell you that the program is trying to connect
to the Internet and asks you how to deal with the program.
Because Internet Guard Dog displays an alert the first time you start an
Internet program, you may want to start each of the Internet-connected
programs you use regularly in order to get those alerts out of the way at one

What File Guardian does
File Guardian can protect files that contain your sensitive data from being
opened, renamed, copied, moved, or deleted. For added protection, you can
even encrypt files protected by File Guardian. Internet Guard Dog can also
alert you if a program attempts one of the following potentially harmful
activities:
• A program attempts to reformat your hard drive.
• An ActiveX control attempts to delete files on your hard drive.
• An ActiveX control attempts to scan files on your hard drive.
• A program attempts to access your system password files.
When Internet Guard Dog displays an alert message, you can decide if the
program shouldbe allowed to continue the operation or not.
Responding to File Guardian alert messages
Internet Guard Dog can d isplay five different File Guardian-related alert

What is McAfee VirusScan?
The VirusScan name applies both to the entire set of desktop anti-virus
program components describedin this chapter, andto a particular component
of that set: SCAN32.EXE, or the VirusScan “on-demand” scanner. “On
demand” means that you as a user control when VirusScan starts and ends a
scan operation, which targets it examines, what it does when it finds a virus,
or any other aspect of the program’s operation. Other VirusScan components,
by contrast, operate automatically or according to a schedule you set.
VirusScan originally consisted solely of an on-demand scanner—features
since integrated into theprogram nowprovide a cluster of anti-virus functions
that give you maximum protection against virus infections and attacks from
malicious software.
The VirusScan on-demand component operates in two modes: the VirusScan
“Classic” interface gets you up and running quickly, with a minimum of
configuration options, but with the full power of the VirusScan anti-virus
scanning engine; the VirusScan Advanced mode adds flexibility to the
program’s configuration options,including the ability to run more than one
scan operation concurrently.

Starting VirusScan
VirusScan comes with a single, default scan operation pre-configured and
ready to run. You can start this scan operation to look for vi ruses on your C:
drive immediately, or you can configure andrun your own scan operations to
suit your needs. VirusScanAdvanced alsocomes witha singlepre-configured
scan operation, which scans all of your local hard disks.

VirusScan looks for viruses in files with the extensions .EXE,.COM,
.DO?, .XL?, .MD?, .VXD, .SYS, .BIN, .RTF, .OBD, and .DLL. Files
with .DO?, .XL?, .RTF, .MD?, and .OBD extensions are Microsoft
Office files, all of which can harbor macro virus infections. The ?
character is a wildcard that enables VirusScan to scan both
document and template files.
• Choosing Action options
When VirusScan detects a virus, it can respond either by asking you what
it should do with the infected file, or by automatically taking anaction that
you determi ne ahead of time. You can specify which response options you
want VirusScan to give you when it finds a virus, or which actions you
want it to take on its own. These response options include:

displayan alert message when it finds a virus and offer you the full
range of its available response options.
• Move infected files automatically. Choose this response to have
VirusScan moveinfected files to a quarantinedirectory as soon as it
finds them. By default, VirusScan moves these files to a folder
named INFECTED that it creates at the root level of the drive on
which it found the virus. For example, if VirusScan found an
infected file in T:\MY DOCUMENTS and you specified INFECTED
as the quarantine directory, VirusScan would copy the file to
T:\INFECTED.
You can enter a different name in the text box provided, or click
Browse to locate a suitable folder on your hard disk.
• Clean infected files automatically. Choose this response to tell
VirusScan to remove the virus code from the infected file assoon as
it finds it. If VirusScan cannot remove the virus, it will note the
incident in its log file.

• Delete infected files automatically. Use this option to have
VirusScan delete every infected file it finds immediately. Be sure to
enable its reporting feature so that you have a record of which files
VirusScan deleted. You will need to restore deleted files from
backup copies. If VirusScan cannot delete an infected file, it will
note the incident in its log file.
• Continue scanning. Use this option only if you plan to leave your
computer unattended while VirusScan checks for viruses. If you
also activate the VirusScan reporting feature, the program will
record the names of any viruses it finds and the names of infected
files so that you can delete them at your next opportunity.
• Choosing Report options

default, the program lists its current settings and summarizes all of the
actions it takes during its scanning operations in a log file called
VSCLOG.TXT. You can have VirusScan write its log to this file, or you can
use any text editor to create a text file for VirusScan to use. You can then
open and print the log file for later review from within VirusScan or from

AInternet Security and Privacy
This chapter provides some background information that will help you
understand Internet security and privacy threats, and discusses strategies for
using Guard Dog to protect yourself and your computer.
Networks and the Internet
A computer network links individual computers together so they can share
data and resources. To network, computers need some means of
connection—either a modem or a Network Interface Card (NIC—some
computers have NICs already built-in). The modem or NIC is responsible for
sending and receiving data through the network. Netw orks are sometimes
called local area networks (LAN) because they link the computers at a single
locale, such as an office or building. In a small office, computers can be linked
directly by connecting them together with cable. This very simple network is
called a peer-to-peer network, wherein all of the computers are equal to one
another. Windows has peer-to-peer networking capabilities built into the
operatingsystem. The increasedtraffic inlarger networksrequires theservices
of a special computer, called a server. Servers help larger networks operate by
figuring out how to route messages to the appropriate recipient.
A
The Internet is avast computer network, connecting computers together from
around world and allowing them to work together and share information.
When you connect to the Internet, your computer becomes a part of a
worldwide network of computers.
TCP/IP is the subsystem
The Internet is based on a system called Transmission Control
Protocol/InternetProtocol (TCP/IP).TCP allows computersto share data by
first breaking it down into little segments called packets. In addition to data,
each packet contains the address o f the machine sending the packet, and the
address of the intended recipient. The TCP part of the system is what is
responsible for addressing the data and breaking into packets. IP, the second
part of the system, is responsible for routing packets from the sending
computer to the recipient computer.Special computers called routers read the
address on each packet, and figure out how to route them to the appropriate
destination.
User’s Guide 55
Internet Security and Privacy
Why packets?
Whygo through all this trouble,breaking data down into packets? Theanswer
lies in the origins of TCP/IP. Like the Internet itself, it is a product of the Cold
War. The United States Department of Defense originally developed the
Internet. It was designed to ensure secure communications, even with
multiple communications network failures anticipated in the event of a
nuclearwar.TCP/IPsolvestheproblemofnetworkfailurebyassumingthat
a certain amount ofnoise alwaysexists in the network— noise referring either
to random data errors or more serious system crashes. If you have ever tried
to speak in a noisy room, you know the necessity of repeating yourself—and
that is exactly what TCP/IP is designed to do. Breaking the data down into
packets allows the Internet to seek alternate routes if one route is inaccessible.
If a packet cannot get through or arrives damaged, the receiving computer
simply requests it again until it arrives successfully.
When you send an e-mail message, for example, it is broken into several
packets. Depending on how noisy the network is, each packet may need to be
routed over a separate route in order to find its way to its destination.
Furthermore, networkproblems may cause some of the packets to be delayed
so they arrive out of order. To compensate, TCP examines each packet as it
arrives to verify that it's OK. Once all the packets are received, TCP puts them
back in their original order. Of course, all of this happens quickly and
automatically, so you will never see the process at work.
The Internet and the Web…what is the difference?
Before the Web, the Internet was mostly command-line driven and
character-based— you had to type in the exact Internet address of the place
youwanted to goa t acommand line. In 1989,Tim Berners-Leeof theEuropean
Particle Physics Laboratoryproposed anew way toshare information over the
Internet. The essential feature in Berner-Lee’s vision of the Web is that it links
documents together. When you click a link on a Web page, you are
automatically connected to another Web site. This linking function, combined
with the increasing graphics abilities of home computers, transformed the
Internet into a graphically rich place, complete with video, sound, and
pictures. Through the linking of information together in a
graphically-appealing package, the Web made the Internet more attractive to
the typical consumer.
The Internet is a network of linked computers that uses TCP/IP as its
underlying messaging system. The World Wide Web (WWW, or just “Web”
for short) is hosted by the Internet, and is an ever-expanding collection of
documents employing a special coding scheme named Hypertext Markup
Language (HTML).

NOTE: HTML is a set of commands designed to be interpreted by Web
browsers. An HTML document consists of content (prose, graphics,
video, etc.) and a series of commands that tell a Web browser how to
display the content.
Privacy and security on the Web
Before the advent of the Web, Internet security usually posed a problem only
forsystem administrators trying tokeep meddlesomehackersaway from their
systems. When the Web arrived, the popularity of the Internet skyrocketed.
Almost overnight, people began doing all sorts of potentially sensitive
activitiesover theInternet, including: banking and stock transactions;sending
personal data toWeb sites;performing Web searches;and orderingbooks and
clothes. While the Web is responsible for making the Internet more accessible,
it also opens new possibilities for data theft, invasions of privacy, and fraud.
Why does Internet privacy matter to me?
Step back and consider the range of sensitive transactionswe makeevery day.
As an example,considera simple ATMtransaction:We assume thatfollowing
conditions prevail whenever we use our ATM cards:
Internet Security and Privacy
• Privacy: Only you and the intended recipient can access the transaction
information. ThePIN youuse to access your bankaccount providesa fairly
high level ofprivacy—as long as you don’tshare your PIN with others,and
don’t leave your card lying around, your checking account balance is safe
from prying eyes.
• Integrity: Nothing can intervene and change the information during the
transaction. When we take twenty dollars out of our checking account, we
have a reasonable expectation that the ATM will not add an extra zero.
• Trust: You can trust that the recipient is who they claim to be; the recipient
cantrustthatyouarewhoyouclaimtobe.
Organizations likebanks and insurancecompanies arelegally obliged toabide
by federal statutes that govern the sanctity of your transaction information.
The problem with Internet is that it has not yet evolved into well-established
institutional mechanisms that guarantee the sanctity of your information.

Internet Security and Privacy
Privacy on the Web
Who is snooping?
Hackers are a breed of human being that thrive on gaining illegal access to
computersin order toaccess, steal, and sometimescorrupt data. Manyhackers
are quitebenign—breaking into asecure system is a challenge and a thrill. But
some computer hackers think that if they don’t care for someone or some
organization, it is OK to break in to their computers and wreak havoc. Other
hackers think that the on-line theft of money and resources i s legitimate, as
long as it goes to support more hacking.
Snooping and sniffing
Since its inception, the Internet has been (and largely remains) an open
network. Opennessmeans that information on the Internet travels without
any special security: Anyone who can monitor network traffic can intercept it.
This sort of monitoring is called “sniffing,” and is easy to perform using
“sniffers.” Sniffers are programs (or hardware devices) designed to monitor
data traveling over a network. Originally, sniffers were designed to help
network administrators track down networking problems. Unfortunately, the
same tool can also be used to steal information. Sniffers are insidious and
difficult to detect.
Sniffing often begins when a hacker breaches the security of a local Internet
Security Provider (ISP). A hacker does not need physical access to the ISP’s
premises—sometimes a telephone line is sufficient (although it is also possible
to sniff with physical access to network cables). Once a hacker compromises
an ISP’s system, the network traffic that travels through the ISP is no longer
secure.
Web servers and firewalls
Secure transactions are only one p art of the problem. When an ISP’s Web
server receives information, the ISP m ust be able to keep the information safe.
Hackers liketo attack the security of Web serversbecause Web server security
is still in its infancy. As a consequence, Web administrators assume that aWeb
server is open to attack, and try to keep them decoupled from other,
mission-critical computers. Some Web applications must, however, interact
with corporate databases, an open door to a clever hacker. One form of
security technology called a “firewall” can close the door, but firewalls are
often maintained poorly,and even in the best environment, cannotsafeguard
certain services.
58 Internet Guard Dog
What can I do to keep my stuff safe?
With sniffer in place, a hacker can intercept credit card numbers and other
private information by capturing data transmissions, and then using
pattern-matching algorithms to filter out the valuable information.
Intercepted credit card info can be sold to criminals, intent on committing
fraud.
To avoid this problem, Web browsers incorporate encryption technologythat
cloaks information and makes it difficult to get at. Encryption is the basic
technique that the Web uses to guarantee information security.
The current encryption standard is called “Secure Sockets Layer” (SSL),
supported both by Microsoft and Netscape, and incorporated in their
browsers. An icon in the browser changes to indicate that SSL is active. When
you make a transaction with SSL active, you can be fairly comfortable that the
transaction is safe.
When you visit an SSL-secured site, the latest versions of Netscape
Communicatorand Microsoft InternetExplorer useavisual cue to tellyouthat
the site is secure. For more information, see Howcan I tell ifa Web site issecure?
NOTE: Guard Dog’s CheckUp lets you know if y our Web browser is
up-to-date. The latest browser versions usually offer an enhanceddegree
of security.
Internet Security and Privacy
How can I tell if a Web site is secure?
Today, many sites use SSL to set up secure commerce on the Web. In addition
to Web server security, the most common Internet browsersprovide feedback
about the security level of the site to which you are currently connected. For
example,NetscapeCommunicatordisplaysa lock iconin the lowerleft corner
of the browser window. If the lock icon is broken, the site is not secure. If the
lock sym bol is notbroken, thesite issecure. In addition, if the lock symbol has
a gold background, the site is using strong, 128-bit encryption.
Recent versions of Microsoft Internet Explorer and America Online browsers
also display security information. For more information about how your
browser indicates the security level of sites, refer to your browsers on-line
help, or the printed documentation.
User’s Guide 59
Internet Security and Privacy
If SSL is so great, what is the problem?
SSL is affected by a couple of problems. One problem is that not everyone has
anSSL-enabledserver or browser.Some Webadministratorsdon’twant to use
SSL because they have to pay for it, and it can also slow down server
transactions. A more onerous problem that affects SSL is the way it is
implemented. It turns out that some developers made incorrect assumptions
aboutSSL,whichmeanssomeolderbrowserversionsarelesssecure.The
good news is that Microsoft and Netscape now coordinate their security
efforts, which means a more s ecure, universal standard for Web security.
What about authentication?
Authentication is a method of assuring that both parties to an Internet
transaction are who they claim to be. For example,if you get account balance
information from your bank, you want to be sure that you are contacting the
bank, and notsome unauthorized entity. Inaddition, thebank wants tobe sure
that they are providing the information to you, and not just to a person who
happens to know your bank account number.
Authentication usually entails entering a user ID and a password. To
circumvent intercepted passwords and IDs, authentication employs
encryption to scramble this information before transmitting it.
NOTE: Certificates are Microsoft technologies designed to guarantee a
person’s identity and Web site security. Personal certificates verify that
you are who you claim to be. Web site certificates verify that a Web site
is secure andwhat it claims to be(so Web sites can’t falsifytheir identity).
When you open a Web site that hasa certificate, Internet Explorer checks
if the certificate is correct. If the certificate is not OK, Internet Explorer
warns you. Certificatesare great,in theory. Theproblem is thatthey only
establish a security standard—Web sites are free to choose to use
certificates, or not.
How does encryption work?
The only way to keep a secret is if you do not tell anyone, and if you do not jot
it down. If you need to share the secret, you can hide it within another
message, and let the intended recipient know how to find it. Computer
encryption hides messages by making the original data unintelligible. The
intent is to garble the data so that it can not be read. Inthis case, the data it self
is useless if access by an unintended recipient.
60 Internet Guard Dog
Internet Security and Privacy
The simplest encryption systems use letter shifting, in which a message is
encrypted by shifting every letter n letters later in the alphabet. For example,
say A is changed to B, and B to C, etc. As long as the recipient knows how you
shifted the letters, they can easily decrypt the message by reversing the
process. Of course, a brute force approach to breaking this sort of encryption
would simply try all possible 26-letter combinations until the final message
was retrieved—not a very strong m ethod of encryption.
Computer encryption uses a much more difficult technique of hiding the
message. Rather than a simple letter-shifting scheme, the original message is
transformed by a mathematical algorithm. The algorithm uses a secret “key”
to scramble the message, and the key is necessary to unscramble it. The key is
similar to a house key: The more teeth a key has, the more difficult it is to pick
the lock. Similarly, “strong” encryption uses keys with many “teeth”—in this
case, bits of data.
Thereare two commonly usedlevelsof encryption. The internationalstandard
is 40-bit encryption, but some sites in the United States use a higher level of
128-bit encryption. The number of bits indicates the length of the key used to
encrypt data. The longer the key, the stronger and more secure the encryption.
On the Web, your browser works with secure Web sites to establish and
manage the encryption that secures information. If your browser security
options include the Secure Sockets Layer (SSL), which ensures
data-transmission privacy, you should turn on this option to facilitate secure
data transmission.
NOTE: Guard Dog’s CheckUp automatically checks your browser’s
security level, and lets you know if you need to change it.
Security on the Web
One of themost exciting Webdevelopments is theevolution of downloadable,
executable programs. Java and ActiveX are tw o tools that help developers
create programs that can “live” inside Web pages, and use your Web browser
to automatically run over the Internet. Java allows Web pages to host small
programs called “applets.” When Java-enabled browsers access a Web page
containing Java, they automatically download and run the applets they find
on the page. This is an intriguing development, since it makes it possible to
download and run programs over the Web. Complete, Web-driven programs
written entirely in Java are on the horizon. ActiveX is a similar technology,
developed by Microsoft.
User’s Guide 61
Internet Security and Privacy
Javacontains an internal securitysystem that addresses securityrisks. ActiveX
uses a differentmodel, based on certificate authentication.Certificates contain
information about who developed the ActiveX code. The idea here is that if
you know who developed the code, it is safe to run it. Both security schemes
offer a level of safety, but no one can yet promise that executable content is
entirely safe.
Nasty applets
One possible security threat is a malign Java or Active X program that attacks
your computer over the Web. A nasty applet might, for example, thwart Java
security by circumventing its security model, and des troy data on your hard
disk, or grab sensitive information from your hard drive. The latest browsers
have done a good job of fixing these issues. As long as you are using the latest
version of your browser, you are protected. To date, there have been no
legitimate reports of hostile Java or ActiveX harming anyone. However, there
is no guarantee that an attack will not happen in the future.
Can I prevent programs from accessing the Internet?
You can use Guard Dog to specify the applications that are allowed to access
the Internet from your computer. Obviously, your default Internet browser is
one of these applications.
If the Guard Dog Gatekeeperis runningin the background while youwork on
the Internet, each time an application tries to access the Internet a dialog box
appears to ask if you want to allow this access once only, always, or never.
Computer viruses and the Web
A computer virus is a small computer program that automatically replicates
itself and spreads from one computer t o another. Viruses may infect
programs, your hard drive, and even some document files that employ
macros. Viruses do not infect data files, but they can create problems that
prevent you from accessing your data. Viruses are not accidents—they are
always created by computer programmers.
PC viruses are similar to biological viruses in that they:
• Are spread from host to host—the “host,” in this instance, is your PC.
• Are very good at reproducing themselves.
• Can wreak havoc on an infected host system.
62 Internet Guard Dog
Biological viruses have proven to be tenacious— modern medicine’s success
in fighting viral infection has, so far, been rather l imited. Fortunately, PC
viruses differ from biological viruses in that they are easier to combat, once
they are identified.
Are viruses really that dangerous?
Bear in mind that your chances of contracting a PC virus are slim, and even
more so,your chancesof contracting a trulyvicious virus. The scariest viruses
are malicious programs that intentionally corrupt or delete the data on your
PC. More benign viruses might simply display a message on your monitor or
make a strange sound, and then disappear. But even the most benign virus
occupies some disk space, andmany remain in memory, whichcan causeyour
PC to crash or behave erratically.
Types of viruses
There are three main types of viruses:
• File or program viruses: A program virus attaches itself to a specific
program on your PC. Since many PC’s share certain files in common (for
example, the DOS program command.com, or the command “dir”),which
make these files tempting targets for virus programmers. Program viruses
are dormant until you run the associated program.
Internet Security and Privacy
• Boot viruses (or Master Boot Record viruses): The boot sector of a disk is
aphysicallocationon thedisk that containsinformationaboutthe disk and
the files it contains. All disks and drives have a boot sector, even if they
aren’t “bootable.” A boot virus infects the boot sector of floppy disks and
hard drives, and are activated when you access or boot from an afflicted
disk.
• Macro viruses: Macro viruses are contained in document files, such as
Microsoft Word or Excel files. These files can contain macros that can
automate your work—but macros canalso be written to dodamage to your
PC. Macro viruses are activated when you open an infected document file.
A final word should be said about hoax “viruses,” whichare not viruses in the
strictest sense of the term. A hoax virus replicates a hoax, spread by
misinformed (if well intentioned) e-mail claiming that if you download a
certain file, or ifyou receive an e-mailwith a certain subjectline, you willinfect
your PC with a virus. E-mail messages are always safe; they are simple text
files, and cannot contain viruses. Attachments to e-mail messages (an
attachment is a file that a message sender attaches to a message—it is
downloaded to your PC when you retrieve the message) can contain viruses.
(If E-mail file access is turned on in Virus Sentry, Guard Dog automatically
scans e-mail attachments before you open them.)
User’s Guide 63
Internet Security and Privacy
How can my PC become infected with a virus?
An important thing to keep in mind is that viruses are spread only when you
run an infected application (or open an infected document file, in the case of
macro viruses). A viruscannot travel overyour telephone line andinfect your
PC on its own. You must first download or copy an infected application and
then run the application in order to infect your PC with a virus.
The only way to entirely avoid virus infection is to do nothing—don’t use the
Internet; never download a file; never accept a diskette from someone else;
never share Word or Excel files. Of course, this draconian “Robinson Crusoe”
cure is unrealistic in today’s computing environment, where sharing data is
the norm and accessing the Internet is an everyday occurrence.
NOTE:Internt Guard Dog offers comeswith McAfee VirusScan whichis
easy to use. It automatically scans your PC for signs of virus infection,
and investigates suspect files before they have a chanceof infecting your
PC.
Viruses are spreadwhen infected diskettes are sharedbetween PCs, andwhen
you download and run infectedfiles from on-line services, bulletin boards, or
the Internet. Another potential (but remote) route for virus transmission is
when you access Web pages that use Microsoft ActiveX technology or Sun’s
Java. Web pages that use ActiveX, for example, can automatically download
programs to your PC, and these programs might be infected with a virus.
Although there isno known casew here ActiveXand Java havespread viruses,
there is still a possibility— remote as it may be—for your PC to encounter a
virusinthisway.
A virus might be hidden in the next file you download, or on a diskette you
borrow —even diskettes purchased at a store. Downloaded shareware is also
a source of infection.
NOTE: Although Java and ActiveX are not, strictly speaking, viruses
(i.e., it can’t spread and replicate), they can still harm your PC. Guard
Dog’s default settings allow it to monitorall Javaand ActiveX activity on
your PC, and warn you before something potentially dangerous occurs.
Frequently asked questions about Internet privacy
What information do Web sites collect about me?
Web sites collect information about you in two major ways.
64 Internet Guard Dog
Internet Security and Privacy
• First, youcan provide the informationyourself whenyou registersoftware
or respond to Internet questionnaires.
• Second, when you ask to be allowed access to the electronic version of a
newspaper, or use a “shopping cart” to buy products on the Web, a cookie,
described in “What are cookiesand howare t hey used?” on page 65,might
be written to your computer where it stores information,such asyour user
ID and password for the newspaper or the articles you bought with their
quantity and price.
What information do companies get when I register products online?
Companies get only the information that you enter in the registration form
when you registerelectronically.They donot getany information about your
computer system, your use of your computer, or other stored information
unless you provide it as part of the registration.
This information is used for the company’s marketing research and to send
you information about new releases, other products, and so on. The
information mightbe sold toother companies,just asmailing listsof magazine
subscribers or mail order companies can be sold to others.
Some companies allow you to specify that you do not want to receive mailings
or to have your name and address sold to other companies. If the company
does not provide this option, you can enter false information to prevent
mailings, either postal or electronic, from reaching you.
What are cookies and how are they used?
A cookie is a small file that contains data. The data in the cookie varies,
depending on its purpose. Upon the request of a Web site, your Web browser
stores cookies on your computer. Usually, cookies just contain information
that enhances your Web experience. For example, when you use an Internet
site to buy computer equipment, you may add items to a “shopping basket.”
Information about the items you add to the shopping basket is stored in a
cookie on your computer because the Internet browser cannot retain
information that youentered inone Internet page when youswitch toanother
Internet page. The cookie saves informationabout your purchasesand allows
the site to create a final order form for you.
Another example is the cookie that a Web store keeps on your computer,
holding your user name and password so that you do not need to enter this
informationeachtimeyouconnecttothesite.
User’s Guide 65
Internet Security and Privacy
Some stores may use the cookie information to record each time you connect
to the site, what pages you use, and whether you click any of advertiser
