You'll need to fill out a self-assessment form, unless you're a larger business that needs to hire third-party auditors. These auditors will assess your business and submit additional paperwork.

The PCI compliance process involves six objectives and 12 requirements. These requirements include implementing firewalls, using antivirus and anti-malware software, and encrypting transmitted cardholder data.

To meet the PCI requirements, you'll need to go through a series of steps, including assessment, reporting, and clarifications. Assessment involves examining the compliance of system components in scope following the testing procedures for each PCI DSS requirement.

Here are the key terms to understand in the PCI compliance process:

  • PCI DSS Scoping: Determining which system components and networks are in scope for PCI DSS for your business.
  • Assessment: Examining the compliance of system components in scope following the testing procedures for each PCI DSS requirement.
  • Reporting: The assessor or entity submits required documentation, like the Self-Assessment Questionnaire (SAQ) or Report on Compliance (ROC), including documentation of all compensating controls.
  • Clarifications: The assessor or entity clarifies or updates report statements (if applicable) upon request of the acquiring bank or payment card brand.

The most recent version of PCI DSS was released in March 2022 and is referred to as version 4.0.

Security Measures

To maintain a secure environment, create a private internet connection that's password protected, and install firewalls and antivirus software on your computer network.

Firewalls are essential in blocking access of foreign or unknown entities attempting to access private data, and they're required for PCI DSS compliance. Your computer's operating system likely already has a firewall as part of its security software, but check to make sure it's operating properly.

Regularly patch and update your anti-virus software, and consider using multi-factor authentication (MFA) to restrict access to confidential payment data to select trustworthy users.

Firewalls are a crucial part of your computer's security software, and they're often the first line of defense against hackers.

You can find a firewall as part of your computer's operating system, but it's essential to check if it's operating properly to ensure your data is secure.

Installing firewalls on your computers and internal network is a must, and it's a requirement for PCI DSS compliance due to their effectiveness in preventing unauthorized access.

Firewalls block access of foreign or unknown entities attempting to access private data, making them a vital security measure.

A private internet connection that's password protected is also a must-have, and it's recommended to use antivirus software on your computer network to prevent data breaches.

Encrypt Transmitted Data

Encrypting transmitted data is a must when handling cardholder information. This means that any data sent to payment processors, home offices, or other locations must be encrypted.

You should never send account numbers to unknown locations, as this can put sensitive information at risk. This is a basic security measure that can help prevent data breaches.

Encryption is a powerful tool that can scramble data so it can't be viewed by just anyone. The PCI SSC recommends using cryptography and security protocols like TLS, SSH, or IPSec to protect cardholder information.

In practice, this means that you should use credit card terminals and PIN pads that are current and compliant with PCI Data Security Standard (DSS). This will help ensure that your systems are secure and up to date.

Vulnerability Scan

Vulnerability scans are a crucial security measure that helps identify potential weaknesses in your network and operating systems. They're an essential part of maintaining PCI compliance standards.

You should perform internal and external vulnerability scans at least quarterly, and always after any major network change. A qualified professional must complete the scan, and afterward, any detected vulnerabilities must be addressed.

Regular vulnerability scans can help limit the threats that can arise from software malfunctions, outdated products, and human error. These scans use a variety of measures, including patch management and configuration management, to help protect data and detect weaknesses.

Penetration testing, on the other hand, must be performed annually. It determines how malicious actors could gain access to valuable information and security assets, and it's essential for identifying vulnerabilities that might not be caught by regular scans.

After scanning and testing, it's essential to remediate any identified vulnerabilities immediately. This is because the nature of taking card payments is highly sensitive, and any issues must be handled right away to protect cardholder data.

Access Control

Access Control is crucial in maintaining PCI compliance. Restricting access to sensitive data is a must, with cardholder data being strictly "need to know." All staff, executives, and third parties who don't need access should not have it.

Having unique IDs for access is also essential. Individuals who do have access to cardholder data should have individual credentials and identification for access, not a single login with multiple employees knowing the username and password.

Physical access to cardholder data must be restricted. Any sensitive data must be physically kept in a secure location, such as a locked room, drawer, or cabinet. Access should be limited, and anytime the sensitive data is accessed, it should be kept in a log.

Access logs are a must-have for PCI compliance. All activity dealing with cardholder data and primary account numbers (PAN) require a log entry. This includes documenting how data flows into your organization and the number of times access is needed.

Using access control measures is vital. Restrict access to any confidential payment data to select trustworthy users. This includes using authentication methods like multi-factor authentication (MFA), unique usernames and passwords, pins, and security tokens to minimize the risk of a breach or unauthorized login.

Proper password protections are also essential. This includes keeping a list of all devices and software that require a password, and changing the password on routers, modems, point of sale (POS) secure systems, and other third-party products.

Monitoring and Maintenance

Monitoring and Maintenance is a crucial aspect of maintaining PCI compliance. Firewalls are essential in blocking access of foreign or unknown entities attempting to access private data.

Having a firewall in place is required for PCI DSS compliance. It's the first line of defense against hackers, making it a must-have for any organization handling card data.

Continuous monitoring is necessary to ensure data security and compliance. This involves mapping internal controls to PCI DSS goals and protecting points where card data enters, gets stored, and exits the organization.

Automating monitoring and assessment processes can save time and reduce costs. At Sprinto, they automate the monitoring and assessment process to ensure visibility and remain PCI compliant throughout the year.

Regular checks can be triggered to ensure compliance, such as verifying password requirements. This helps fix patches that need fixing when patches show up, ensuring data security.

A secure network is also essential in preventing data breaches. This includes installing firewalls, antivirus software, and using a private internet connection that's password protected.

Policies and Procedures

Documenting your policies is a crucial step in becoming PCI compliant. You'll need to document inventory of equipment, software, and employees with access to cardholder data, as well as logs of accessing cardholder data.

Inventory includes equipment, software, and employees with access, which all need to be accounted for in your documentation. This includes how information flows into your company, where it is stored, and how it is used after the point of sale.

Mapping your policies and controls to the PCI framework is also essential. This involves identifying and eliminating out-of-scope items, and automating the PCI compliance process can make this task much more manageable.

Documenting your policies is a crucial step in maintaining compliance. This includes creating an inventory of equipment, software, and employees who have access to sensitive information, such as cardholder data.

To ensure you're documenting everything correctly, you'll need to log all instances of accessing cardholder data. This will help you track how information flows into your company, where it's stored, and how it's used after the point of sale.

Creating a detailed information security policy is also essential. This policy should outline the steps you'll take to maintain compliance with PCI standards, and it should be regularly reviewed and updated to ensure it remains effective.

Remember, documenting your policies is not a one-time task - it's an ongoing process that requires regular maintenance and updates.

What Happens When You're Absent

Being absent from following policies and procedures can have serious consequences. The cost of non-compliance can range from $5,000 to $100,000, depending on the nature of the non-compliance.

Your business's reputation can take a hit, with each non-compliance instance flagged as a security violation. This can lead to significant reputational damage.

Non-compliance can also result in the loss of access to promote card-based technology transactions on your business platforms.

Penalties for Non-Compliance
