Before you get on the internet think
of this:
| The popularity of the
Internet and of the World Wide Web can cause
major complications when that brand new
Microsoft Windows-based PC arrives on your door step.
For many people, a new computer has not officially arrived
until you surf your first Web page. In fact, many
manufacturers want you to get on the Internet to register
your new PC as part of the initiation process. However,
connecting a new PC to the Internet before you take the
steps necessary to close the security vulnerabilities
is just asking for trouble. According to
Sophos research, there is a 50 percent chance of being
infected by an Internet worm in just 12 minutes of
being online using an unprotected, unpatched Windows PC.
This download lists the 10 things you should do to a
new PC before you even consider connecting it to the
Internet. Since TechRepublic is a community of IT
professionals, I'm sure there are many ideas floating around
about what steps to take when preparing a new PC for its
first foray onto the Internet? |

I received a great new Windows XP machine , I love it, but
I'm having a hard time getting it all set up. How can I get
all my files and software from my old machine onto the new one?
I've transferred some of my smaller files via floppy disk, but
I'm not sure how to get the rest transferred. I know there's no
simple answer, but any tips anyone could give would be greatly
appreciated.
Windows XP comes equipped with a utility called the
"Files and Settings Transfer Wizard," designed to facilitate
the movement of both documents and personal settings from your
old computer to the new one. Thanks to this utility,
transferring everything, from the entire contents of your My
Documents folder to your network and/or dial-up connections
data, screensaver, and display preferences to your Web browser
and e-mail client customizations, is simplified. As long as your
old computer is running a Microsoft operating system from
Windows 95 or later, you should be able to run the wizard
without trouble.
Unfortunately, this tool will still require you to manually
install many of the programs in your old computer onto your new
one. As implied in its name, the Windows XP "Files and
Settings Transfer Wizard" will transfer some program
files and program settings, but it will not
install programs. Still, the wizard is arguably one of the
more pragmatic approaches to the task at hand - and you already
have it in your PC.
Understand, you might be better off manually installing programs
onto your new computer for a number of reasons:
1. Clean installations of software repair files that might have
become corrupted over time - possibly solving subtle software
conflicts present in your old computer.
2. You are likely to be notified of updates, fixes and new
program versions during installation. It's possible to transfer
everything from your old computer, only to end up having to
update a significant number of programs right away!
3. Transferring a program also transfers all of the junk left
behind by previous upgrades. A clean installation avoids this
problem, and keeps your new hard drive from collecting junk
right away.
4. Some of the programs in your old PC - or newer versions of
them - might already be installed in your new PC.
5. Programs copied from backup disks and drive images (clones)
might not actually be installed, and the missing registry
entries might prevent you from starting them, uninstalling them,
or both.
6. Reinstalling software gives you a chance to determine whether
some programs are truly needed, or simply taking up space in
your hard drive. There's no point in transferring a three
year-old copy of Real Player when you listen to your music files
through iTunes.
Even if you have to reinstall a bunch of programs manually,
doing so will still be less painful and less time-consuming than
relying on floppy disks.
Before running the Wizard, there are some measures you can take
to get everything ready:
Start by making a list of the programs present in your old
computer. You can use it to keep track of what you need to
install, as well as to identify entries that might be redundant
or completely unnecessary.
Because the Wizard will not install programs but rather merely
transfer some of their settings, you should start by installing
your firewall, antivirus and other security software, as well as
programs that you frequently use. As you'll see later, the
Wizard will alert you to any other programs that ought to be
present in your new computer if their settings are to be
transferred.
Next, you need to decide on the physical means by which the data
will move from your old computer to the new one. The best choice
for moving large amounts of data is a network. In the absence of
a network, your best bet would be connecting the computers
directly using a null modem serial cable. You can find
this inexpensive cable at electronics stores and those carrying
office and computer supplies, such as Comp USA and Staples.
A third option would be using removable media such as CD-Rs and
DVD-Rs. The Files and Settings Transfer Wizard will essentially
back up files from your old computer onto the blank media, then
restore them to your new machine. However, this process will be
significantly more tedious and time-consuming than using a
direct cable, and it should be reserved for situations in which
relatively small amounts of data are being migrated.
Once you have settled on a transfer method, make sure the
antivirus and antispyware software in your old computer are up
to date, and scan the machine thoroughly. There is no reason to
migrate infected and worthless files!
Now let's get started.
You can find an excellent discussion on how to use the Files and
Settings Transfer Wizard here:
http://www.microsoft.com/windowsxp/using/setup/expert/crawford_november12.mspx
I've distilled some of the information in that and other
Knowledge Base articles below. Still, it wouldn't hurt to read
that article to get an overview of the task at hand, or to refer
to it afterward to help you put everything together.
To run the Files and Settings Transfer Wizard, simply
click the START button on your new computer, then
click ALL PROGRAMS / ACCESSORIES / SYSTEM TOOLS / FILES AND
SETTINGS TRANSFER WIZARD. If you have any questions
regarding how to connect your computers before proceeding, click
on the appropriate link on the wizard's welcome screen. (The
wizard will give you a chance to connect the computers at a
later time.) Once you are ready to proceed, click NEXT.
The wizard then asks you whether the computer you are using is
the new computer, or the old one. Make sure New Computer
is selected, and click NEXT. The wizard will prepare your
computer for the next step.
At this point, you are informed that the wizard needs to be run
in your old computer as well, and are given the choice to either
use your Windows XP CD, or create a Wizard Disk. If your new PC
came with a Windows XP CD-ROM, select this option. Otherwise,
insert a blank disk in the appropriate drive in order to create
a Wizard Disk. Click NEXT to proceed to the Go now to your
old computer screen. (You will need to return to this
screen once the files are collected from your machine. If at
some point you need to install programs on this new PC before
their settings can be transferred, close the wizard, install the
software, then repeat the above steps to get back to the Go
now to your old computer screen.)
Now you are ready to collect files and settings from your old
computer. The next steps will vary slightly depending on your
previous choice:
If you chose to use a Wizard Disk:
(The following steps are taken from
http://support.microsoft.com/kb/306187/en-us)
1. Insert the Wizard Disk into the appropriate drive in
your old computer.
2. Click Start, and then click Run.
3. In the Open box, type:drive:Fastwiz
Where drive is the drive that contains the Wizard Disk
(such as A:Fastwiz).
4. Click OK
5. On the Welcome to the Files and Settings Transfer
Wizard screen, click Next.
6. On the Select a transfer method screen, click the
transfer method that you want, then click Next.
7. On the What do you want to transfer? screen, click the
selection that you want, and then click Next. I recommend you
click on Both files and settings. Note that when
you make a selection, a summary of the items to be transferred
appears in the Based on your current selection, the following
items will be transferred list on the right side of the
wizard. If you wish, you can scroll down the list to verify that
everything you want (for example, mp3s) will be transferred.
8. The wizard will now collect your files and settings. If you
selected a removable media in step 6, you are prompted to insert
the media (floppy disk, or other removable media) and then click
OK.
9. On the Completing the Collection Phase screen, click
Finish.
If you chose to use your Windows XP CD-ROM:
(Instructions taken from
http://support.microsoft.com/kb/306186/en-us)
1. Insert the Windows XP CD-ROM into the CD-ROM or
DVD-ROM drive.
2. Right-click Start, click Explore, and then open the
Support\Tools folder on the Windows XP CD-ROM.
3. Double-click the Fastwiz.exe file to start the
Files and Settings Transfer Wizard.
4. Click Next.
5. Click Old Computer, and then click Next.
6. Click the transfer method that you want to use, for example,
floppy drive or other removable media, and then click Next.
7. On the What do you want to transfer? screen, click the
selections that you want to transfer, and then click Next.
8. The wizard will now collect your files and settings. If you
selected a removable media in step 6, you are prompted to insert
the media (floppy disk, or other removable media) and then click
OK.
9. Click Finish.
Regardless of the method chosen, the Files and Settings Transfer
Wizard may alert you of programs that need to be installed in
your new computer before their settings can be transferred.
Chances are, some of the entries might be older versions of
programs, or software you might not wish to install. If the list
contains a program you want, install it in your new computer
before proceeding. Otherwise, you can safely ignore the message.
Once the files have been collected, go back to the Go now
to your old computer screen on your new computer, and
follow the instructions. The wizard will guide you through the
rest of the process.
Congratulations! Your new XP computer should now have a familiar
feel and look, and contain most if not all of the files present
in your old machine.

Identity Theft
No
matter what you do online, there is
always a risk that someone could glean
enough private information about you to
usurp your identity. Your financial
credit affects nearly every facet of
your life, so in order to maintain
control over your information, the
following tech tips are in order. There
are several types of information that
are appealing to thieves:
- Credit card
numbers
- CW2 security
numbers
(those 3- or 4- digit codes on the
back of your credit cards)
- Credit reports
- Social security
numbers
- Driver’s license
numbers
- ATM cards
- Telephone
calling cards
- Mortgage
information
- Dates of birth
- Online passwords
- PIN numbers
- Home/business
addresses
- E-mail addresses
- Phone numbers
|
Compromised Accounts
When
any of account is compromised, close it
immediately. E-mails can “phish” for
information about you. If an e-mail
sounds like it is from Pay-Pal or your
bank telling you there is a security
concern, and you should click the
embedded link to go the site to correct
it, DON’T! These links are often
tailored to take you to look-alike Web
sites designed to trick you into
entering your personal information
directly into the malicious hacker’s
computer. What you should do instead i s
open your Web browser and manually type
in the link to the Web site you wish to
visit to check on your account (don’t
ever cut and paste a link). This is the
only way you can be reasonably certain
you won’t be misdirected to someone
waiting to prey on your information.
Sometimes it isn’t even your fault. The
security at some companies that have
your personal information is lax and
vulnerable to a malicious hacker attack.
|
Low Tech Backups
In any case where you suspect that your
information has been stolen, you need to
be prepared and to have organized your
paper bank records for at least one
year. You will need to prove your
account balance to the financial
institution’s fraud department as soon
as possible. Detailed steps to take if
your ID is stolen can be found at the
following links:
|
Online Passwords
 The
biggest Achilles’ heels are online
passwords. To protect yourself, always
use combinations of upper and lowercase
characters (including symbols and
numbers) so that hackers who concentrate
on commonly used words in the dictionary
won’t guess it easily. Use longer words
with more characters and combine two
words together with a symbol. You may
even want to use words from two
different languages so that automated
password guessing tools won’t work.
Computers aren’t the only way thieves
can get your personal information.
Telemarketers are often hardworking
people, but there are those who are
persistent for the wrong purposes. If
someone calls you and hassles you to
give them your personal information,
don’t! Even if they sound legit, you
never know to whom you are talking to
over the phone.

Voice over IP Privacy
|
The
Bush Administration is asking the Federal
Communications Commission (FCC) to order Net
telephony providers to comply with a law
that would permit police to wiretap
conversations carried over the Internet.
Unlike regular voice calls, where wiretaps
would have to physically connect to the
line, VoIP could be tapped anywhere at
anytime. The problem that forces us to
sacrifice our privacy and rights stems from
the FBI’s belief that Internet telephone
calls are a national security threat that
must be countered with new police
wiretapping rules. The way this would work
is that the FBI would require broadband
Internet providers to provide more
efficient, standardized surveillance
facilities, effectively changing the way
Internet providers do business.
The reasons for these changes are because
a terrorist could potentially use VoIP to
circumvent legitimate wiretaps from calls
being placed over the Internet. If
terrorists can evade lawful electronic
surveillance though technology, it puts
everyone at risk. The real trick is to find
a new way in which to effectively trace
Internet phone conversations. The federal
government is funding the development of
surveillance tools through scientific
projects that would allow police to identify
whether suspects have been using VoIP to
communicate secretly.
VoIP communications are hard to track.
Think about the great expanse of the
Internet where traffic can go literally
anywhere. Vonage and ATT phone adapter boxes
are portable and can be installed virtually
anywhere in the world. You can take your
box, plug it into the Internet halfway
across the world and still receive calls on
your local phone number. |
Anonymity
 If
that’s not enough, there are a number of
services on the net that make your
Internet traffic go through a special
service that removes all tracing
information, making you invisible or
anonymous to the world. When such
services are used, it becomes almost
impossible to wiretap a call. The only
way around this problem is to work with
the VoIP providers directly by placing
tracing information embedded within the
VoIP call itself. In this way, if
traffic is routed through an anonymous
server, there is still a way to find out
who the call is coming from/going to and
trace the people on each end of the
call. Privacy advocates, however, are
infuriated by the federal government’s
initiatives to have the ability to tap
our VoIP calls at will. They see this as
a direct attack on our privacy. VoIP
providers are nonetheless working with
the FBI and FCC to facilitate the
approval of wiretapping requirements so
that the Internet does not become a
haven for secret communications between
terrorists and spies.
|
Conclusion
Everything you do online can be tracked
whether it is making a purchase through
a website or calling someone using your
internet phone adapter—you must be very
careful not to give out personal
information that could potentially be
used against you.
We live in a wired world, and finding
anonymity amongst the digital media is
difficult if not impossible. Keep
records, burn information on CDs that
are not readily accessible over your
home network or local computer. If you
are detail-oriented about your personal
information, you can save yourself many
headaches later on.

Tech Tip 56 - Keeping Windows Clean
By Stewart S. Miller
Windows
is a living entity. Protecting Windows and
keeping it clean from malware (malicious
programs) is a full time job these days.
Windows users are often frustrated by
Microsoft’s continued efforts to make its
operating system secure against hackers
because patching Windows seems like a
full-time job. The real question here is
what do all these patches mean to you?
Microsoft releases “critical” alerts on a
regular basis designed to protect Windows
from hacker attacks. The most severe
vulnerabilities deal with security bugs that
allow hackers to gain complete control over
your computer. Some of these flaws exist in
the way Windows Media Player and MSN
Messenger process certain files. Microsoft
has also identified bugs in how Exchange
(its Internet Mail Server Software) and
Office allow hackers to execute hostile code
on vulnerable systems. These patches are
supposed to prevent a hacker from gaining
unauthorized access to certain sections of a
Web site. Another bug in the Windows Shell
Component may permit a hacker to cause an
affected system to stop responding. These
vulnerabilities make it possible for hackers
to spy on your PC. With the advent of
Service Pack 2, it seems like updates are a
seamless process that simply execute in the
background. The problem with this “easy”
method of installation is that you, as the
user, need to know what is being changed on
your computer. This is why I recommend you
always view the list of updates before
allowing Windows to update your system.
|
Security Updates
One
Microsoft security patch update includes a
change to the functionality of a clear-text
authentication feature of Internet Explorer.
This update removes the ability to handle
user names and passwords in HTTP URLs, HTTP
with Secure Sockets Layer (SSL), URLs, and
HTTPS URLs. An example of the type of URL
that is no longer supported would look like:
http(s):// username:password@server.com If
you think your version of Windows is too old
to be affected by these security concerns,
think again. Windows 98, Windows 98 SE, and
Windows Millennium Edition are all
critically affected by these security
vulnerabilities too. If you are running
Windows NT 4.0 Workstation SP6a or Windows
2000 Service Pack 2, update support ceased
at the end of last year. Microsoft
encourages those users to migrate to a
“supported” version of Windows to prevent
potential exposure to these security
vulnerabilities.
|
Protection Settings
 You
can take steps to protect yourself from
future attacks. Set your Internet and local
intranet security zone settings to “high” so
your computer will prompt you before running
ActiveX controls and active scripting in
these zones. Setting your browser security
to “high” applies the highest level of
protection from unsafe content that comes
across your network. If this setting causes
some of your sites not to load properly, you
can add those sites individually to your
list of trusted sites. However, you should
only do so if you are sure that the site is
safe to use and is hosted from a company or
entity you trust. As a final note, there is
a free program that I highly recommend you
download called the “ Microsoft
Baseline Security Analyzer” (MBSA) tool
that verifies when a security update has
been applied to your system. It lets you
scan your system for missing security
updates as well as common security
misconfigurations.
|
Firewalls
|
Once upon a time, a firewall
was your best answer to protecting your computer
from hackers looking to exploit vulnerabilities
in Windows. Unfortunately, this isn’t always the
case now. Nowadays, most users are attacked by
just browsing the Web. Hackers host Web sites
that contain code to exploit vulnerabilities in
your operating system such as infect you with a
virus, spyware, or even take complete control of
your computer. Hackers can alternatively
compromise a Web site for the purpose of
misdirecting you to click on malicious content.
Hackers can’t “force” you to visit a specific
site, but they can trick you into clicking on a
link that invites malicious content into your
machine.
Windows XP SP2 has an
integrated firewall, previously known as the
Internet Connection Firewall (ICF) that defends
you against hackers who are trying to access
your computer from the Internet without your
permission. When a hacker attempts to connect to
your computer via an “unsolicited request,” the
Windows firewall blocks that request. Windows
will actually ask your permission if you wish to
“unblock” and allow connects to programs you
actually want to run such as instant messaging
and multiplayer network games. When you unblock
those connections, the Windows firewall creates
an exception so that the firewall won’t ask any
more when your program needs to receive
information to function. You don’t have to use
the Windows firewall. You can install and run
any firewall you wish.
Zone Alarm is an excellent
firewall that is very popular.
Zone Alarm offers both paid and free
versions that can protect your computer as much
or as little as you desire. An even more
comprehensive program is
Norton Internet Security 2005 that touts its
ability to hide your PC on the Internet so
hackers can’t find it. The Mac also has an
integrated firewall, just like Windows. However,
Norton also makes a comprehensive security
solution for this platform as well in the form
of
Norton Internet Security 3.0. The best part
of Norton Internet Security 2005 for the PC is
its integrated “Intrusion Detection System” that
automatically blocks suspicious traffic. Not
only does this product block suspicious incoming
connections, but it lets you configure your
“outbound” Internet connections too. This is
advantageous, because if you do get infected
with spyware, Norton will alert you that a
program on your system is attempting to connect
to the Internet and asks you if you really want
this program to connect. By giving you the
opportunity to block these connections, you can
effectively thwart malicious spyware from doing
its evil. |
Intrusion Detection
Apple’s Macintosh has its own version of
this type of Intrusion Detection with a
program called,
“Little Snitch” that effectively asks
your permission any time a program wants to
connect to the Internet. Although the Mac
seldom becomes infected with spyware, it is
a handy utility to have so that you know
exactly what your computer is doing on the
Internet.
|
Frozen Images
Now that your computer has been through its
trial by fire(wall), the best answer is to
simply put your computer on ICE! If you have
resigned yourself to the fact that, no
matter what you do, your computer is going
to get infected, then use a program called
“Deep Freeze”. This software for both
Mac and PC lets you configure your computer
with all the programs you need and then
“freeze” your configuration. If a hacker
infects your computer with a virus or
spyware, Deep Freeze makes the damage simply
disappear. All of your settings, files and
programs are completely restored to their
original configurations every time you
restart your computer. This makes it
possible for you to avoid problems caused by
software conflicts, registry and operating
system corruption, lost network and Internet
connections, as well as a host of problems
caused by simply connecting to virus-ridden
network sites. The only catch is that you
have to store your personal documents on a
separate drive that does not “revert” each
time you restart your machine. You have to
imagine this program literally resets your
computer to a frozen state that you specify.
However, if you create a word document, it
would be lost if it were on that drive. So,
remember to keep a separate drive with your
personal files and you’ll have a computer
that won’t ever become infected or go down.
Now, all you have to worry about are
mechanical failures.
|
Conclusion
|
Finding ways to prevent hackers from
accessing Windows is difficult because your
operating system is always in a constant
state of flux. Every time you turn on your
computer, browse the web, or get a Microsoft
update, your operating system changes. If
you want to prevent all changes from taking
place on your computer, freeze the
computer—but then you can’t make any changes
to your operating system at all.
There are good and bad points
to both approaches—but in a world where having a
functional computer is a necessity—this Tech Tip
will keep your system running. |
