What is PCI Compliance?

pci compliance is an important part of merchant services. pci dss compliant

“PCI compliance” may initially sound like a jumble of intimidating jargon, but it holds the key to the trust and security of payment card data.  

The Payment Card Industry Data Security Standards (PCI DSS) establishes the fundamental benchmark for data security. Specifically, obtaining PCI compliance means that an organisation has reached this benchmark in their efforts to safeguard sensitive data.  

When merchants process transactions, they take on the responsibility of ensuring customer payment details are secure. If this data is not secure, customers are opened up to fraud. Because of this, adherence to PCI standards will make sure that your business maintains trustworthiness and ethical practices.  

At New Payment Innovation, we recognise the unique challenges small and medium-sized businesses face in Ireland’s payment landscape. That’s why we offer PCI-compliant merchant services customised to fit the needs of Irish SMEs.  

Since 2014, we have been a leading PCI-compliant merchant service provider, leading the path to secure payments for businesses in Ireland.

The History of PCI Compliance

PCI DSS was established in 2004 by the five major credit card companies: American Express, JCB, Discover, Visa, and Mastercard. Initially it provided the first unified security standards, and it was determined that all merchants processing more than 20000 card payment transactions a year must be compliant.  

In the nearly two decades since its inception, the organisation has undergone several iterations. Generally, these have included security updates, management, and expanded guidelines. PCI DSS 4.0 was released in March 2022 and included updates to multifactor authentication, eCommerce standards, and password requirements. In addition, it also included standards for using modern payment options like digital wallets.  

6 Principles of PCI Compliance

The PCI Security Standards Council (PCI SSC) has established a comprehensive framework for PCI DSS, comprising six overarching objectives: 

1. Establish and Maintain a Secure Network and Systems 

First of all, organisations must maintain robust network security to ensure secure credit card transactions. This includes the deployment of resilient and intricate firewalls that guarantee adequate protection without disrupting the experience of cardholders and vendors. For wireless local area networks, specialised firewalls are available to counteract eavesdropping and malicious attacks. Additionally, the ongoing use of vendor-provided authentication data, such as personal identification numbers and passwords, is discouraged. 

2. Protect Cardholder Data 

Secondly, PCI DSS requires safeguarding cardholder information, regardless of where it’s stored. Specifically, crucial data repositories containing information like birthdates, mothers’ maiden names, phone numbers, and mailing addresses must be securely protected. The transmission of cardholder data across public networks must be encrypted to fortify data security.

3. Maintain a Vulnerability Management Program 

 Next, organisations dealing with card services must implement a risk assessment and vulnerability management program to shield their systems from malicious hackers, including spyware and malware. Ensuring that all applications remain free from vulnerabilities and bugs that might be exploited for data theft or tampering is crucial. Likewise, regular updates and patching of software and operating systems are important. 

4. Implement Strong Access Control Measures 

Robust access control is vital, ensuring that access to system information and operations is restricted and meticulously monitored. Chiefly, every user of the system should be assigned a unique and confidential identification name or number. Furthermore, physical protection of cardholder data is mandatory, which might encompass document shredding, limitations on document duplication, secure disposal methods, and heightened security at points of sale. 

5. Regularly Monitor and Test Networks 

 Continuous network monitoring and testing are critical to verify the effectiveness, currency, and proper operation of security measures. Particularly, antivirus and antispyware programs should consistently receive the latest updates and signatures, conducting thorough scans of all data exchanges, applications, RAM, and storage media. 

6. Maintain an Information Security Policy 

 Finally, organisations must establish and adhere to a formal information security policy that is diligently followed by all participating entities. In some cases, enforcement measures like audits and penalties for noncompliance may be necessary to ensure the policy’s effectiveness. 

PCI Compliance Regulations in the EU

There are 12 PCI compliance requirements  outlined by the PCI Security Standards Council. Maintaining PCI compliance means making sure each og the 12 standards is upheld. 

1. Establish and Maintain Firewall Security

 This involves the installation and ongoing maintenance of a robust firewall. It includes rigorous testing of network connections, restricting access to untrusted networks, and implementing various protective measures. 

2. Modify Default Vendor Passwords and Security Settings

 To enhance security, it’s essential to change default passwords and security settings provided by vendors. This also encompasses enabling only essential services, removing unnecessary functionalities, and encrypting access. 

3. Safeguard Stored Cardholder Data

 Protecting stored cardholder data entails creating policies for data disposal, limiting the types of data that are retained, and refraining from storing specific data types. 

4. Encrypt Cardholder Data During Transmission 

 When transmitting cardholder data across open, public networks, encryption is imperative. In other words, merchants must refrain from sending unprotected account numbers via email, instant messaging, text, chat, or other user-end messaging technologies. 

5. Utilize and Maintain Antivirus Software 

 Employ and regularly update antivirus software. This entails performing and documenting routine scans and ensuring the continuous operation of this essential protective layer. 

6. Develop Security Systems and Processes 

 Establish comprehensive security systems and processes. This involves creating procedures to identify and address vulnerabilities and other security efforts. 

7. Limit Access to Cardholder Data to a Need-to-Know Basis 

 Restrict access to cardholder data based on necessity. Define access requirements for various roles, establish user privileges, and implement control systems, among other measures.

8. Assign User IDs for All Computer Access 

 Ensure that all individuals with computer access have designated user IDs. Additionally, put authentication methods in place, document policies in this domain, and take relevant actions. 

9. Control Physical Access to Cardholder Data  

Implement controls to restrict physical access to cardholder data. Sometimes, this can involve using cameras and other tools to monitor sensitive areas and the handling of specific equipment. 

10. Monitor and Track Network and Data Access  

Establish a system to track and monitor who accesses networks and cardholder data. This includes maintaining an audit trail, utilizing time-stamped tracking tools, and reviewing logs for any suspicious activity. 

11. Regularly Test Systems and Processes  

Conduct routine testing of systems and processes. This includes inventorying wireless access points, performing quarterly vulnerability scans, and monitoring network traffic, among other testing procedures. 

12. Enforce an Information Security Policy  

Lastly, maintain a comprehensive policy on information security. Typically, this entails creating, publishing, and disseminating a policy at least annually. The policy should outline usage rules for specific technologies and set out responsibilities for all involved parties, among other important aspects.
