What is PCI DSS? Concept, compliance level and requirements to understand Picture 1

PCI DSS (Payment Card Industry Data Security Standard) is a security standard developed to ensure that all payment card processing companies maintain a secure environment. This standard includes a series of requirements to protect customers' card information, thereby helping to minimize the risk of fraud and data loss. Let's learn more with  TipsMake  right below.

What is PCI DSS?

PCI DSS was created in 2004 by the Payment Card Industry Security Standards Council, a global organization comprised of major companies such as Visa, MasterCard, American Express, Discover, and JCB.

The original goal of the standard was to provide a common set of rules for organizations in the financial industry to protect payment card information from potential threats. By establishing a common standard, PCI DSS has created a solid foundation that businesses can rely on to improve security and reduce risks associated with sensitive data. Over time, the standard has been updated to reflect new trends and challenges in the field of data security.

Complying with PCI DSS requirements not only protects your organization from credit card breaches, but also builds trust with your customers. When customers know their information is well protected, they are more likely to make transactions and engage with your brand.

Who should use the PCI DSS standard?

The PCI DSS standard is not only for banks or financial institutions but also extends to many different fields. So who should care about this standard?

Credit card processing business

From small retail stores to large e-commerce sites, PCI DSS compliance is required. This includes managing and protecting customer card information to prevent cyberattacks. Planning and implementing effective security measures not only protects customers, but also protects businesses from major financial risks in the event of a data breach.

Payment Service Provider

Payment service providers such as PayPal, Stripe, and Square are also subject to PCI DSS compliance. They act as intermediaries in processing transactions between customers and businesses, and therefore have a special responsibility to protect credit card information.

Financial and banking institutions

Financial institutions and banks not only process transactions but also store customers' credit card information. Compliance with PCI DSS requirements is critical to ensure that this sensitive information is protected from security threats. Banks need to conduct regular assessments and implement security measures to ensure they remain resilient to rapidly changing technology and new attack methods.

Application developers

Applications that deal with online payments need to pay attention to the PCI DSS standard. They need to integrate security measures into their applications right from the development stage to avoid exploitable vulnerabilities.

PCI DSS Compliance Level

Each business or organization will be required to comply with PCI DSS at different levels depending on their size and type of operations. There are four levels of PCI DSS compliance, from lowest to highest. Businesses are classified according to the number of credit card transactions they process each year:

● Level 1: For businesses that process more than 6 million card transactions per year. These businesses are typically required to undergo an annual security audit by a third party.

● Level 2: Applicable to businesses that process 1 to 6 million card transactions per year. Must conduct their own security assessment and submit a report to the bank.

● Level 3: For businesses that process 20,000 to 1 million online card transactions per year. A security assessment is required but no third party is required.

● Level 4: For businesses that process less than 20,000 online card transactions per year. Requires a self-assessment and reporting the results to your bank.

At any level, the PCI DSS compliance assessment process will include testing the security elements of the system, generating reports, and implementing corrective actions if necessary.

12 Requirements of the PCI DSS Security Standard

The PCI DSS standard includes 12 specific requirements, each with its own criteria for protecting card information.

1. Install a firewall: Businesses need a strong firewall to control the flow of information in and out.

2. Change default passwords: Businesses need to ensure that all default passwords are changed upon first use.

3. Protect card data: Businesses need to encrypt credit card data during transmission and storage to prevent bad guys from accessing this information.

4. Store data securely: Not only store card data securely, but also delete unnecessary information as soon as it is no longer in use.

5. Access Control: Only necessary personnel should be allowed access to credit card information. This should be done through a clear authorization system.

6. User authentication: Businesses need to establish a strong user authentication process, including the use of strong passwords and two-factor authentication capabilities.

7. Limit access to cardholder data: All access to card information should be logged and monitored to detect unusual behavior early.

8. Each visitor must have a unique ID: Limits physical access to cardholder data.

9. Perform security testing: Security tests should be performed periodically to detect and fix weaknesses in the system.

10. Monitor and record access; All cardholder access to the network and data should be monitored and recorded.

11. Regularly review and evaluate security procedures: Train and raise awareness for employees

12. Maintain information security policies for employees and contractors: Businesses need to organize regular training sessions so that employees clearly understand the importance of security and the procedures to be followed.

Benefits of businesses complying with PCI DSS standards

PCI DSS compliance is not only an obligation but also brings many benefits to businesses. Here are some of the outstanding benefits.

- Protecting customer information: When customer information is securely protected, businesses will reduce the risk of cyber attacks and data leaks. Customers will feel more secure when making transactions, thereby increasing the reliability and brand value of the business.

- Increased customer trust: When a business demonstrates its commitment to information security, it builds trust with its customers. Consumers today take security very seriously, and PCI DSS compliance is a sign that a business is serious about protecting their information. This trust not only helps drive sales but also creates long-term, sustainable relationships with customers.

- Avoid financial risks: Every time a data breach occurs, businesses can incur large fines from banks and other financial institutions. Businesses also have to take corrective measures to restore their systems and reputation. PCI DSS compliance helps businesses avoid these serious financial risks.

- Improve internal processes: Businesses will have to review and optimize the way they operate, thereby improving performance and service quality. This process not only helps businesses comply with PCI DSS but also creates a more efficient working environment for employees.

Conclude

PCI DSS is an important standard that every business involved in payments and processing credit card information must comply with. From protecting customer information to building trust and minimizing financial risk, PCI DSS compliance is not only a legal requirement but also a smart strategy for sustainable development.

Remember that security is not just an IT responsibility, but an organization-wide responsibility. Therefore, businesses need to invest in educating and raising security awareness for all employees.
