Encrypt Cardholder data
Credit card information must always be encrypted. Particularly, when such information is inadvertently or intentionally transferred over a shared or public network, data encryption is a necessity. According to recent updates, only TLS version 1.2 or higher should be used for encryption to ensure security. Even the encrypted cardholder data should only be accessible to a restricted employee group. Additionally, the sharing of encrypted data over potentially risky platforms such as messaging apps should be blocked.These should be your first steps to make your business PCI DSS compliant.
Consider using dial-up terminals
Older network technology is arguably more secure from digital threats.Using dial-up terminals instead of IP terminals could be an effective way to prevent security breaches and hence ensure DSS compliance. Dial-up terminals,being analoguein their function,eliminate the danger of a data breach altogether.They may be slower than IP terminals, but the lack of speed is compensated by the added security.
Segregate payment networks
One essential step to ensure DSS compliance is to use a separate network to process payments. This kind of network segmentation can be achieved through firewalls or by even using different hardware for payment transactions. The network that your employees use for their daily jobs would thus be segregated from the network over which financial transactions are conducted. This will curb the hacking of credit card data and save you a lot of effort on enforcing compliance.
Conduct frequent penetration tests
Once you have segmented your payment portals, you must monitor their effectiveness regularly. Penetration tests allow you to do exactly that. They help you identify the loopholes in your organization’s security pipeline.Such tests are conducted from the perspective of an intruder as if the organization’s data is under imminent danger of being stolen.These tests should thus only be conducted by trustworthy experts in the field.
Choose the right payment providers
Your work is half done if your payment providers maintain high standards of security. So,if you choose a payment provider that satisfies PCI level 1 compliance standards, you are already a step ahead in ensuring DSS compliance.Level 1 standards are the most stringent to follow.Remember that you still need to be confident of the consistency ofthe payment provider’s adherence to DSS compliance. Take your time and make an informed choice.
