What is PCI?
Payment card industry (PCI) compliance is a set of rules that ensures the safety of a customer’s credit card information. All businesses that process, store, or transfer credit card information must maintain a secure environment.
Major card companies—including American Express, Discover, JCB International, MasterCard, and Visa—established the Payment Card Industry Security Standard Council (PCI SSC) to develop and manage payment card security. The PCI Security Standards Council has many standards and supporting materials, like frameworks, tools, and resources to help organizations ensure protect stored cardholder data.
Maintaining PCI compliance lowers the risk of data breaches, protects confidential data, and helps businesses boost their brand name. A credit card company’s security protocol is incomplete without PCI compliance, and these companies typically require and mention this in their agreements when working with one another.
PCI compliance steps for an organization
Any business that accepts credit card payments, big or small, must be PCI compliant. This means that the organization must follow the rules set by the PCI Security Standards Council.
This typically involves following these five steps.
Step 1: Understand your organization’s PCI level.
Any organization’s PCI level is determined based on the number of annual transactions it processes.
- Level 1: An organization with more than 6 million transactions per year that has also been the victim of a breach that compromised card holders’ confidential data.
- Level 2: An organization processing between 1 to 6 million transactions annually.
- Level 3: An organization that conducts 20,000 to 1 million transactions annually.
- Level 4: An organization with an annual processing volume of under 20,000 transactions.
Step 2: Learn the 12 PCI standards.
Your organization must comply with these 12 PCI Data Security Standards (DSS) to be PCI compliant:
- Install and maintain secure systems and applications such as a firewall to ensure that cardholder data is protected.
- Instead of using default settings, protecting passwords with security measures that users can change and are unique to each user.
- Implement both physical and virtual protection to prevent data breaches.
- Encrypt any data about the cardholder sent through open or public networks.
- Install, maintain, and update antivirus software.
- Develop and maintain secure systems and apps in a way that actively searches and fixes vulnerabilities.
- Restrict physical access to cardholder data in the organization to avoid data theft and security issues.
- Implement role-based access control (RBAC) to authenticate and thoroughly identify users with access to sensitive information.
- Limit access to cardholder data that you physically keep.
- Monitor and track network resources and cardholder data using logs.
- Test security systems and their resources regularly.
- Assign a policy that addresses information security for all personnel to ensure employee awareness.
Step 3: Complete self-assessment questionnaire (SAQ).
The SAQ thoroughly examines your organization’s compliance with the 12 standards specified above. Each questionnaire is a set of yes or no questions to establish how closely your firm complies with the PCI DSS criteria.
For a PCI level one organization, a PCI-approved auditor verifies its compliance with the standards. Based on your SAQ, your organization can hire an approved scanning vendor (ASV) to look for security flaws and ensure that it meets all the standards. The questionnaires differ for different businesses for levels two to four, guided by the level of compliance you must meet and the number of transactions you have per year.
Step 4: Protect cardholder data and your network.
At its core, implementing strong access control measures to protect stored cardholder data is the most fundamental aspect of PCI compliance. After installing, configuring, maintaining secure systems and applications, have your employees set up a strict password policy. Tokenizing sensitive card data allows businesses to keep it safe and secure.
Step 5: Complete official attestation of compliance (AOC) form and submit documentation to credit card companies.
Finally, step five is crucial for completing the process. Organizations use the AOC form to certify that their PCI DSS evaluation—as indicated in an SAQ or PCI compliance report—has been a success.
Then, you submit SAQ, ASV, and AOC reports to financial institutions, such as banks and credit card firms, and to all the companies with which your organization does business.
PCI compliance audit
You must carry out a yearly PCI audit with a qualified security assessor (QSA) or the company’s internal security assessor. A PCI audit evaluates the security of your company’s payment software from all aspects.
To be compliant, your organization must meet the 12 PCI DSS requirements to receive a Report on Compliance (ROC). Initial audits can take two years, and self-assessment can take up to a year.
The PCI audit process has three steps.
Scoping defines the assessment parameters for your PCI audit. The organization’s crucial task is to pin down all sites and workflows with cardholder data. Annually scope all systems before your assessment, as PCI Audit is yearly.
2. On-site audit assessment
To analyze network security, along with all its devices, policies, and protocols, QSA carries out a comprehensive onsite audit evaluation.
The QSA’s duties are to:
- Guide and approve the evaluation scope.
- Document and verify all organizational and technical documentation.
- Ensuring the use of PCI data security protocols.
- Guide your organization through the audit process.
- Determine whether PCI DSS standards are satisfied.
- Attend the whole audit process.
- Submit a detailed final report.
3. Continue monitoring PCI standards
To maintain compliance with the PCI DSS, organizations must regularly monitor their network systems, policies, and activities. Many organizations perform routine PCI scanning, pen testing, and event log monitoring to ensure that all PCI data security measures are according to standards.

PCI regulations are so complex that it can be challenging to comply on your own. Organizations must meet all PCI-DSS standards to be compliant. Non-compliance with PCI DSS exposes firms to customer loss, credit card company fines, data breaches, and lawsuits.
Installation of network security, data encryption, malware prevention, filling the competency gap and defining scope, and other aspects for clusters and networks is a hectic task. Once an organization is compliant, sustaining it is extremely difficult. You must test systems often and resolve issues immediately.
Trend Cloud One can solve these difficulties with its continuous compliance monitoring, which includes automated real-time security and compliance checks. It makes the PCI compliance process very easy to achieve and maintain. Contact Trend Micro to learn how to minimize your network and workload PCI compliance concerns.
