How to comply with PCI – And why you should!

How to comply with PCI – And why you should!

PCI what?

PCI DSS is the Payment Card Industry Data Security Standard. It is a set of data security requirements  that must be followed by everyone who takes any type of card payment. In the current COVID-19 lockdown shops are closing their doors, either permanently or until they get the go-ahead from the government to reopen.

With people only allowed to leave home for a select few reasons, we are seeing more and more businesses turning to apps or websites as a survival mechanism allowing customers to buy their goods.. Even my local butchers now offers online shopping for collection or delivery.

What business new to this way of working may not realise is that the PCI DSS applies to every organisation that takes card payments. This means it is their responsibility to ensure that they are compliant, even if the payment processing is fully outsourced to a PCI DSS compliant third party.

The requirements

The PCI DSS is a set of the following 12 requirements:

  1. Install and maintain a firewall configuration to protect cardholder data
  2. Do not use vendor-supplied defaults for system passwords and other security parameters
  3. Protect stored cardholder data
  4. Encrypt transmission of cardholder data across open, public networks
  5. Use and regularly update anti-virus software or programs
  6. Develop and maintain secure systems and applications
  7. Restrict access to cardholder data by business need-to-know
  8. Assign a unique ID to each person with computer access
  9. Restrict physical access to cardholder data
  10. Track and monitor all access to network resources and cardholder data
  11. Regularly test security systems and processes
  12. Maintain a policy that addresses information security for employees and contractors

Merchant levels

There are different levels of merchant where the PCI DSS is concerned and the level that the merchant falls into will determine how compliance to the standard is confirmed:

Level 1: merchants with over 6 million transactions a year, across all channels or any merchant that has had a data breach.

Level 2: merchants with between 1 million and 6 million transactions annually, across all channels.

Level 3: merchants with between 20,000 and 1 million online transactions annually.

Level 4: merchants with fewer than 20,000 online transactions a year, or any merchant processing up to 1 million regular transactions per year. In general, levels 2, 3 and 4 can confirm compliance by completing a Self-assessment Questionnaire (SAQ), however there are exceptions to this rule and your Acquiring Bank can advise further.

Level 1 merchants must have a formal assessment conducted by a PCI Qualified Security Assessor (QSA) who will confirm compliance via a Report on Compliance (RoC).

SAQs

If businesses are able to confirm compliance by completion of an SAQ there are different types depending on the way the business operates and the setup of the payment processing activities. It is important to get this right from the start to ensure that the correct security controls are being applied to protect the card payments.

If in doubt, seek advice before progressing down a compliance route as this could save time and money.

Non-compliance

Non-compliance with the PCI DSS can lead to an insecure environment that may be a target for card data thieves. In the event that a breach does occur, and compliance can’t be proven, the fines will be higher and a forensic investigation will need to be carried out at the cost of the merchant. Furthermore, following a breach the merchant is obliged to have a QSA conduct an assessment and produce a RoC at their own expense.
