# What is the PCI DSS?

The PCI Data Security Standard (PCI DSS) was defined based on existing security standards from VISA and MasterCard and is by now adopted and recognized by all well-known credit card firms as common standards. The standard defines specific requirements in the different areas of payment card processing, which have to be met by merchants, service providers, payment application vendors, acquirer banks and processors. Please find more information at the PCI Security Standards Council (opens new window).

# How often do I have to provide the PCI DSS validation?

The PCI DSS validation must be provided at least once a year. Since the PCI DSS validation documents the current status of credit card processing in your company, you are required to react to changes in credit card acceptance or payment processing outside the specified cycle of one year by updating your PCI DSS validation.You are required to maintain PCI DSS compliance at all times.
If your validation includes ASV scans, your validation must be renewed every 90 day by ASV scan.

# Why is PCI DSS compliance so important?

This question is indeed asked by many who are faced with the requirements of PCI DSS. For the processing of your payments you sometimes come into contact with sensitive payment data. When handling such credit card data, you assume the responsibility to keep it secure and confidential. You bear this responsibility towards your merchant bank (acquirer) and the credit card companies as well as your customers. The corresponding verification for this is provided by the measures resulting from the PCI Data Security Standard (SAQ as Self-Assessment, ASV scans, audits) and make your compliance with security standards transparent.

Why is compliance with these security standards so important? To understand the importance of the PCI DSS, you need to know that hackers are targeting your customers' cardholder data. Hackers try to learn the primary account number (PAN) as well as sensitive authentication data whih they could use to impersonate the cardholder, use the card, and steal the cardholder's identity.

Sensitive cardholder data can be stolen at various points:

  • Unprotected card reader
  • Paper stored in a filing cabinet
  • Data from a payment system database
  • Hidden camera that records the entry of authentication data
  • Stealthy access to your store's wireless or wired network.

These gateways for hackers must be kept closed. By complying with PCI DSS, you demonstrate that sensitive cardholder data is secure with you and handled responsibly, so that hackers will not be able to tap into it. In addition, you may face consequences if you fail to comply with the PCI DSS.

# What are the consequences of PCI DSS non-compliance?

Your company can be fined by the credit card organizations or your acquirer (merchant bank). Furthermore, your company is liable if credit card data of your clients is stolen or misused. Apart from possible fines, you may also incur consequential damage to your image.

# What are the 12 key requirements of PCI DSS?
