1. CRUCIAL STEPS
How to Protect Your Online Shop:
11

2. Get a SSL Certificate
SSL (Secure Sockets Layer) is a standard technology that keeps all the
sensitive information sent between you and your customer encrypted
and protected from fraudsters.
The address of an SSL-secured website
begins with https rather than http. When
customers see a lock icon on the address
bar, they recognize your website as secure
and reliable.

3. Comply with PCI DSS
Every online merchant and every payment
service provider must comply with
Payment Card Industry Data Security Standard (PCI DSS).
In brief, PCI DSS is a compulsory set of
requirements that you are supposed to
meet in order to reduce the risk of any
criminal activity related to storing and
processing card data.

4. Activate 3D Secure
3D Secure protects buyers against
unauthorized card use and significantly
reduces online fraud. Cardinity activates 3D
Secure tool for every client free of charge.
3D Secure is an additional layer of security. It is an authentication
window marked with MasterCard SecureCode or Verified by Visa logos
in which a customer has to enter a personal security code.

5. Verify CVV/CVC
Request your customers to type their CVV (Card Verification Value)
or CVC (Card Verification Code) code (a 3-digit number located on the
back of your credit or debit card) which serves as the card’s security code.
Your customer should provide this number in order to verify that he/she
actually has the physical card.

6. Identify Signs of Fraud
Some common signs of fraud:
Make sure that the email address provided by a customer exists. Fraudsters usually use email
addresses which have no meaning.
Fraudsters tend to fill in their own address in the shipping field and the address of the legitimate
cardholder in the billing field.
In order to stay anonymous, fraudsters usually use postal boxes for their orders.
Unusually high amount of an order can be a signal of a fraudulent activity. Similarly, a very small
order should attract your attention if it is followed by a sequence of large orders.
Pay special attention to the transactions conducted with the same payment card but different
shipping addresses and vice versa.

7. Apply Blacklisting
In case you have already faced hacker attacks or
fraudulent activities, you can blacklist a particular
untrustworthy customer and his IP address, and he
will never be able to purchase in your online shop
again. You can keep a record of the information
about suspicious customers and blacklist them not
only by IP address but also by e-mail address, credit
card number, country or city.

8. Put Up Firewalls
Setting up a firewall will prevent cyber attacks from happening in your
network. A firewall monitors traffic that comes to your server. It warns you
in case of any suspicious activity and blocks malicious attacks.
Remember to properly configure a
firewall in order to permit legitimate
users to access your network.

9. Do NOT Store Cardholders’ Data
Make sure that after a successful
payment authorization, you do not
store any private cardholder data,
such as CVV codes, card expiration
dates, etc.

10. Implement Password Policy
It won’t take long for hackers to get a simple 5-character password. That is why
you should encourage your customers to use stronger passwords for logging in
their accounts in your e-shop.
***********
USER_ID
Develop the password policy,
so that the passwords could
not be too simple or too short.

11. Update Regularly
In order to keep your online shop
protected, update your system and
software regularly. Don’t forget that your
SSL certificate also needs to be renewed
from time to time. In addition, get rid of all
the outdated and unnecessary plugins. The
latest versions of software usually have all
the bugs fixed.

12. Choose a Reliable Payment
Service Provider
If you choose a payment service provider
like Cardinity that complies with PCI DSS,
credit and debit card payments carried
out on your e-commerce website will
become much safer.We will safeguard
you and your customers as well as take
care of your transactions.
