Understanding the Payment Card Industry Data Security Standards (PCI DSS)
In this article, I will be talking about Payment Card Industry Data Security Standards (PCI DSS). Payment Card Industry Data Security Standards (PCI DSS) is a set of security standards created to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment. These standards are designed to protect the privacy and security of credit card information and reduce the risk of fraud and data breaches.
In this blog post, we will discuss the key aspects of PCI DSS and provide an overview of the requirements that companies must meet to comply with these standards.
The Payment Card Industry Security Standards Council (PCI SSC) was founded in 2006 by major credit card companies, including Visa, Mastercard, American Express, and Discover. The PCI SSC is responsible for developing and maintaining the PCI DSS standards.
The PCI DSS standards apply to all companies that process credit card transactions, regardless of their size or location. This includes merchants, processors, acquirers, issuers, and service providers.
The PCI DSS Requirements :
The PCI DSS standards consist of 12 requirements, each of which is divided into sub-requirements. These requirements are designed to ensure that companies that process credit card transactions maintain a secure environment that protects cardholder data from unauthorized access, use, disclosure, and destruction. The 12 requirements are as follows:
- Install and maintain a firewall configuration to protect cardholder data.
- Do not use vendor-supplied defaults for system passwords and other security parameters.
- Protect stored cardholder data.
- Encrypt transmission of cardholder data across open, public networks.
- Use and regularly update anti-virus software or programs.
- Develop and maintain secure systems and applications.
- Restrict access to cardholder data by business need-to-know.
- Assign a unique ID to each person with computer access.
- Restrict physical access to cardholder data.
- Track and monitor all access to network resources and cardholder data.
- Regularly test security systems and processes.
- Maintain a policy that addresses information security for all personnel.
PCI DSS Compliance :
PCI DSS compliance is mandatory for all companies that accept credit card payments. Companies that fail to comply with these standards may be subject to fines, penalties, and legal action. Additionally, non-compliance can result in reputational damage, loss of customers, and decreased revenue.
To achieve PCI DSS compliance, companies must undergo an annual assessment by a Qualified Security Assessor (QSA) or an Internal Security Assessor (ISA). The assessment determines whether the company meets the requirements set forth by the PCI SSC.
There are four levels of PCI DSS compliance, which are determined based on the volume of credit card transactions processed by a company. Level 1 is the highest level of compliance and applies to companies that process more than 6 million transactions per year. Level 4 is the lowest level of compliance and applies to companies that process fewer than 20,000 transactions per year.
