PCI DSS Compliance (Checklist, Requirements, How to Check, etc.)
Contents
Navigating PCI DSS compliance can be challenging for businesses handling payment card information. This comprehensive blog post offers a detailed checklist of requirements, steps to verify compliance, and practical tips for implementation.
Whether you’re a small business or a large enterprise, understanding PCI DSS is crucial for safeguarding sensitive data and maintaining customer trust. Explore the essential components of compliance and learn how to effectively manage your security posture to meet industry standards.
What Is PCI DSS Compliance?
PCI DSS Compliance entails adhering to the Payment Card Industry Data Security Standard (PCI DSS). This comprehensive set of security standards aims to ensure that all companies accepting, processing, storing, or transmitting credit card information maintain a secure environment. Ultimately, this compliance is critical for protecting cardholder data from theft and for securing and strengthening payment transaction systems. By following these standards, organizations can enhance their overall security posture and foster trust with their customers.
PCI DSS Compliance Checklist
Here’s a brief overview for each key item in the PCI DSS compliance checklist:
Secure Network Configuration
Ensure that firewalls, routers, and other security measures are properly configured to protect cardholder data from unauthorized access.
Protect Cardholder Data
Encrypt cardholder data and apply data masking techniques to prevent unauthorized access or theft, both during transmission and storage.
Vulnerability Management
Regularly scan systems for vulnerabilities and keep antivirus software up to date to defend against malware and other security risks.
Access Control
Limit and monitor access to sensitive data based on job roles. Ensure only authorized personnel can access cardholder information.
Monitoring and Testing
Continuously monitor network traffic and conduct regular system testing to detect any suspicious activity or security flaws.
Information Security Policy
Establish a formal security policy that defines procedures for maintaining data security, including regular updates to reflect new threats.
This checklist is designed to help companies comply with PCI DSS standards and protect cardholder data.
To Whom Does PCI DSS Compliance Apply
The Payment Card Industry Data Security Standard (PCI DSS) applies to any organization, irrespective of size or number of transactions, that accepts, transmits, or stores any cardholder data. Here’s a breakdown of entities to whom PCI DSS typically applies:
Merchants
Any entity that accepts payment cards bearing the logos of any of the five members of the PCI SSC (Payment Card Industry Security Standards Council) — Visa, MasterCard, American Express, Discover, and JCB.
Service Providers
Any entity that processes, stores, or transmits cardholder data on behalf of another entity is considered a service provider. This includes payment gateways, payment processors, and hosting providers, among others.
Financial Institutions
Banks, credit unions, and other financial entities involved in payment card processing should comply with PCI DSS to ensure the secure handling of sensitive information.
Payment Application Vendors
Companies that develop payment applications, particularly those handling cardholder data, must adhere to security standards such as PA-DSS (Payment Application Data Security Standard). This standard, which falls under the broader PCI compliance umbrella, ensures that these applications meet necessary security requirements. Consequently, compliance with PA-DSS not only protects sensitive information but also enhances overall security within the payment processing ecosystem. Therefore, organizations should prioritize these standards to mitigate risks effectively.
Other Entities
Organizations involved in payment card processing, including third-party service providers and vendors, must also adhere to PCI DSS compliance. Their products or services can impact the security of cardholder data, making compliance essential for safeguarding sensitive information.
PCI DSS Compliance Standards
Here is a brief overview of the six main goals and their corresponding PCI DSS standards:
Build and Maintain a Secure Network and Systems
This involves installing and maintaining firewalls, routers, and other security systems to protect cardholder data from unauthorized access. Security measures should be updated regularly.
Protect Cardholder Data
Encryption and masking of cardholder data are necessary to prevent unauthorized access. Sensitive information should be securely stored and transmitted.
Maintain a Vulnerability Management Program
Organizations must regularly scan and update systems to identify and fix vulnerabilities. This also includes using antivirus software and monitoring for threats.
Implement Strong Access Control Measures
Only authorized individuals should access cardholder data. This involves setting strict user authentication protocols and monitoring access logs.
Regularly Monitor and Test Networks
Continuous monitoring and testing are essential for identifying weaknesses and ensuring that security measures are functioning as intended. This includes regular logging and reviewing of activity.
Maintain an Information Security Policy
A comprehensive security policy should outline how data security is managed and maintained. It should be updated regularly and communicated to all employees.
PCI DSS Compliance Levels
Different levels of PCI compliance exist based on the volume of transactions processed annually. These levels determine the specific compliance validation requirements for merchants and service providers:
- Level 1
Merchants processing over 6 million card transactions per year. - Level 2
Merchants processing 1 to 6 million transactions per year. - Level 3
Merchants processing 20,000 to 1 million ecommerce transactions per year. - Level 4
Merchants processing fewer than 20,000 eCommerce transactions per year or all other merchants processing up to 1 million card transactions per year.
How to Get PCI DSS Compliant
So what are some things that can be done if an organization that deals with sensitive data does not have the necessary resources to achieve PCI-DSS compliance?
First, have an independent IT security audit performed by a proven outside company against the PCI-DSS framework. An IT security audit will produce organizational risks that may be overlooked on the surface, but can shed light into the current state of the information security environment.
Additionally, an IT security audit will have a proper action plan to remediate all out of compliance areas.
Second, adopt a formal information security policy that follows industry best practices and controls. Put in place a vendor management program that does due diligence before purchasing payment processing applications. Have follow up assessments to ensure that the infrastructure still conforms to best practices and the PCI-DSS compliance requirements.
These steps are the first toward achieving PCI-DSS compliance. Effective IT governance is essential for maintaining a robust information security program. The Target breach highlights the need for organizations to pay closer attention to the POS-related changes in PCI-DSS 3.0 standards.
What This Means For Businesses (SMBs)
Since 2005, more than 80% of card data breaches have involved small businesses. In such cases, if a business is found to be non-compliant, major brands such as Visa are likely to suspend their accounts.
Smaller business owners may not know that the Best Practice 6.6 security standard went into effect on June 2008, which requires merchants to tighten security. All eCommerce websites are required to conduct application code reviews and install website firewalls.
Be aware of the requirements for small to medium sized businesses. For Visa compliance, level 2 and 3 Merchants must complete annual Self Assessments and quarterly network security scans. Level 4 merchants must also complete an annual PCI Self-Assessment, but in some cases they are not required to complete the quarterly network scan.
It’s worthwhile for all business owners to take the time to understand their compliance requirements for each of the credit card brands they use. This is especially true of smaller merchants that are more often attacked by cyber criminals and identity thieves.
