PCI Compliance Guide
Since 2005, a staggering 11 billion consumer records have fallen prey to over 8,500 data breaches, as highlighted by The Privacy Rights Clearinghouse. Recognising the urgency to bolster consumer data protection and restore faith in the payment landscape, leading payment giants Visa, Mastercard, American Express, Discover, and JCB united to establish the Payment Card Industry Security Standards Council (PCI SSC). Prior to its inception, each of these titans operated under individual security standards, albeit with similar objectives. Their collaboration through the PCI SSC led to the birth of a unified policy, the PCI Data Security Standards (PCI DSS). This robust standard promises an unparalleled layer of security, safeguarding both consumers and banks in today's digital age.
An introduction to PCI Compliance.
What is the meaning of PCI Compliance?
​
The Payment Card Industry Data Security Standards (PCI DSS) is the gold standard for data security in the financial sector. Established to safeguard consumer data and bolster trust in the payment ecosystem, PCI DSS is a must-know for any organisation dealing with cardholder data. In this comprehensive guide, we delve deep into the intricacies of PCI compliance, offering insights and actionable steps to ensure your organisation remains compliant.
​
Why is it important to know what is PCI Compliance?
​
Imagine the chaos if credit card information was easily accessible to hackers! PCI Compliance acts as a shield, protecting sensitive data and ensuring that businesses uphold the highest standards of security. It's not just about protecting data; it's about building trust with your customers.
Key components of PCI-DSS compliance.
Requirements for PCI DSS
​​Think of these rules as the “goals” that the PCI DSS policies are meant to achieve.
​
All 12 rules link to a main idea. These ideas are:
​
- Build and keep a safe network
- Protect cardholder information
- Manage weaknesses in systems
- Set strong access rules
- Check and test networks often
- Have a clear security policy
​
If these rules are followed, the payment card system is secure.
​
The PCI SSC made these rules to protect cardholder information. They include both technical steps and everyday practices.
​
These rules apply to anyone who handles cardholder data. This includes merchants, ISVs, and service providers. If you store, process, or send cardholder data, you must follow these rules. Even mobile apps must comply, so understanding the standards is crucial.
​
Here are the 12 rules of PCI DSS:
​
1. Set up and maintain firewalls to protect cardholder data.
2. Avoid using default passwords or settings from vendors.
3. Keep stored cardholder data safe.
4. Encrypt cardholder data when sending it over public networks.
5. Use and update anti-virus software often.
6. Create and maintain secure systems and apps.
7. Limit access to cardholder data based on business needs.
8. Give each user a unique ID for computer access.
9. Control who can physically access cardholder data.
10. Track and record all access to systems and cardholder data.
11. Test security systems and processes regularly.
12. Write and follow a security policy for all employees.

​​​​​​​​​​​​​​Tools for assessing PCI-DSS compliance
​
The PCI SSC establishes the PCI Security Standards. However, each payment card brand operates its own compliance programme, with distinct validation levels and enforcement measures. For further details on compliance schemes, please liaise with the payment brands or your acquiring bank.
​
Qualified Assessors: The Council oversees programmes designed to aid in evaluating compliance with the PCI DSS. These include the Qualified Security Assessor (QSA) and the Approved Scanning Vendor (ASV). QSAs are sanctioned by the Council to review compliance with the PCI DSS. Meanwhile, ASVs are authorised by the Council to ensure adherence to PCI DSS scanning criteria by conducting vulnerability scans on the internet-facing setups of merchants and service providers. The Council also offers PCI DSS training for Internal Security Assessors (ISAs).
​
Self-Assessment Questionnaire: The Self-Assessment Questionnaire (SAQ) serves as a validation instrument for eligible organisations that opt to self-evaluate their PCI DSS compliance and aren't mandated to provide a Report on Compliance (ROC). Various SAQs cater to different business settings.
Key insights for PCI-DSS compliance.
The PCI DSS stands as the paramount security benchmark worldwide for all entities engaged in the storage, processing, or transmission of cardholder and sensitive authentication data. Its primary objective is to establish a foundational layer of protection for consumers, acting as a formidable shield against fraud and potential data breaches throughout the payment landscape. This standard is pertinent to any organisation that plays a role in payment card transactions and applies to any business regardless of it's size
​
To achieve PCI DSS compliance, organisations must focus on three pivotal components:
​
-
Secure Data Capture: This involves ensuring that sensitive card information provided by customers is gathered and relayed with the utmost security.
-
Robust Data Storage: The PCI standard delineates 12 security domains that organisations must adhere to. These encompass measures like encryption, continuous monitoring, and rigorous security testing to guarantee safe access to card data.
-
Annual Validation of Security Controls: Organisations must routinely confirm that the mandated security protocols are operational. This validation process can encompass a range of tools and methods, from forms and questionnaires to external vulnerability assessments and comprehensive audits by third parties. The subsequent guide provides a detailed breakdown of the four tiers of requirements.

​
Navigating the intricacies of card data management
​
Certain business frameworks necessitate the direct management of sensitive credit card information during payment processes, whilst others can bypass this requirement. For firms directly interacting with card data, such as accepting raw PANs on their payment portals, the onus is on them to adhere to the exhaustive 300+ security controls stipulated by PCI DSS. This responsibility extends beyond mere compliance; it demands the acquisition, deployment, and consistent upkeep of dedicated security software and hardware, even if the card data momentarily passes through their servers.
​
Conversely, for companies that can sidestep the direct handling of sensitive card details, it's prudent to do so. Leveraging third-party solutions, like Paytia Secure Virtual Terminal, offers a streamlined approach. These platforms adeptly capture and safeguard card details, significantly diminishing the associated intricacies, financial implications, and potential hazards. As a result, with card data remaining away from their servers, such companies find themselves tasked with just 22 security controls. Many of these are elementary, such as the adoption of robust passwords.
​
​
Secure data storage
​
For organisations that handle or store credit card information, pinpointing the exact scope of their cardholder data environment (CDE) is paramount. The PCI DSS characterises the CDE as the ensemble of individuals, methodologies, and technologies engaged in the storage, processing, or transmission of credit card details – and any interconnected system.
Given that the comprehensive 300+ security prerequisites of PCI DSS are tailored for the CDE, it's crucial to adeptly segregate the payment framework from other business operations. This strategic segmentation is pivotal in narrowing down the scope for PCI validation. Should an organisation falter in achieving precise segmentation of the CDE, the ramifications are extensive: every PCI security measure would be mandated for each system, laptop, and gadget within its corporate nexus. A daunting prospect, indeed.
​
​
The annual pain of PCI-DSS validation
​
Every organisation, irrespective of its mode of card data acceptance, is obligated to complete a PCI validation form annually. The methodology for validating PCI compliance hinges on several determinants, as elucidated below.
Here are three conceivable situations where an organisation might be beckoned to demonstrate its PCI compliance:
​
-
Payment processors might necessitate it, aligning with their mandatory reporting obligations to the card brands.
-
Prospective business associates might stipulate it as a foundational condition for forging business collaborations.
-
For platform enterprises, which act as conduits for online transactions amongst diverse user groups, it might be a demand from customers. This serves as a testament to their clientele that data is managed with utmost security.
​
The contemporary PCI DSS version 3.2.1 encapsulates 12 primary stipulations, further branching out into over 300 nuanced sub-requirements that echo the zenith of security protocols.
