Online
Do's
Make sure you are purchasing
merchandise from legitimate and
reputable sources. Contact the
company directly if in doubt.
Purchase merchandise
directly from companies that
hold the trademark or the
official legal right to produce
or sell a product.
Try to obtain a physical
address rather than merely a
post office box and a phone
number, call the seller to see
if the number is correct and
working.
Send emails to the
persons/organizations you are
dealing with to see if they have
an active email address. Pay
attention to sellers who use
free email services where credit
cards aren't required to open
the account.
Be cautious when responding
to profitable offers (especially
through unsolicited emails).
Be cautious when dealing
with individuals/companies from
outside your own country.
Make sure you know who the
company is and where it is
physically located. Businesses
taking place in cyberspace may
be in another part of the
country or in another part of
the world. Resolving problems
with unfamiliar companies can be
more complicated in
long-distance or cross-border
transactions.
Inquire about returns and
warranties.
Verify with other websites
the person/company you are
dealing with. Compare the prices
and quality of products with
other suppliers if you are
offered an unexpected reasonable
deal from an unknown
salesperson. Check the seller's
reputation. Many websites
provide the buyers' feedback on
sellers' business practice. This
can help you find the sellers
transaction history.
Use only one credit card to
purchase online. Also consider
opening a credit card account
for use only online in order to
minimize the potential access an
attacker may have to your credit
card information. Keep a minimum
credit line on the account to
limit the amount of charges an
attacker can get.
Ensure yourself that the
credit card transaction is
secure. Watch the address bar at
the top of the computer screen.
When you are asked to provide
financial account information,
Social Security number, or other
sensitive personal data, the
letters at the beginning of the
address will change to "https".
Pay attention to the URL of
a web site. Malicious web sites
may look identical to legitimate
ones, but the URL may use a
variation in spelling, a
different domain (e.g., .com vs.
.net) or an IP address.
Password protect all your
accounts. Don't use easy
detectable ones such as: name,
telephone number or date of
birth.
Password-protect your
computer files and network.
Use new Personal
Identification Numbers (PIN's)
and passwords, if you are
closing existing accounts and
opening new ones.
Memorize all your passwords
and PIN's.
Cancel all credit cards that
you do not use or have not been
used in 6 months. These can be
easily used by thieves.
Cancel your lost/stolen
credit cards as soon as
possible. Get new ones, and use
different PIN's from the
previous ones.
Use anti-virus, firewalls,
email filtering or email
attachment blocking software.
Don't's
Do not purchase merchandise
unless you are certain you deal
with reputable sources.
Do not buy from sellers who
don't hold the trademark or the
official right to produce or
sell a product.
Do not give out your credit
card number(s) online unless you
are 100% sure you are dealing
with a secure and reputable
website. Sometimes an icon
placed at the bottom of the page
symbolizes a higher level of
security. Still, this icon is
not a guarantee of a secure
site, but it might provide you
some assurance.
Do not trust a site just
because it claims to be secure.
Do not believe websites that
tell you your financial or other
sensitive information doesn't
have to be encrypted.
Do not reveal financial or
personal information about
yourself in emails .
Do not respond to emails
requesting for personal or
financial information.
