How Often Should You Audit For PCI Compliance? Best Practices

It is an era of digital payments and ensuring cardholder data security is extremely complex and paramount for businesses of all sizes. 29% of companies establish their PCI DSS compliance after a year of validation. This alarming situation highlights the need for regular PCI compliance audits.

Now, the question is how often should PCI compliance be conducted? PCI Security Standards Council recommends assessment should done quarterly.

The frequency of the audits can based on various factors depending on the volume of transitions and payment of card and brand requirements. For instance, merchant processing for level 1 requires over six million transitions annually.

These transitions must be minimal and there should be one on-site audit per year. Smaller businesses need different audit cycles.

This can based on different requirements. They can require self-assessment for a whole year.

PCI audits are crucial because non-compliance can result in worse consequences. These consequences can include data breaches and penalties.

In this digital online transitions are the norm. protecting sensitive payment card information is predominant.

The Payment Card Industry Data Security Standard (PCI DSS) provides the framework to protect cardholder data and information.

Regular audits with ongoing PCI DSS compliance help in identifying and analyzing vulnerabilities to strict security standards.

This blog will help you understand the best practices for maintaining PCI DSS compliance, and actionable insights to help organizations handle the complexities of PCI compliance.

What Is PCI Compliance?

PCI DSS (The Payment Card Industry Data Security Standard) is a set of security standards established to ensure that all organizations, companies, and businesses accept, process, store, or transmit card data and information for a secure environment.

The PCI compliance meaning is more than just regulatory requirements. It is a prominence of protecting customers sensitive data and maintaining trust in your business operations.

These standards are established by the Payment Card Industry Security Standards Council (PCI SSC). these protocols protect cardholder data and reduce data breach risks.

The requirements of PCI DSS are detailed and cover every aspect of data security. Businesses that accept, process, store, and transmit data must comply with these security standards.

The primary goal and focus of these standards are to ensure the security of customer’s data.

The non-compliance of these requirements can result in fines and penalties. It can even lose the ability to process credit card payments.

The PCI DSS constitutes 12 core requirements. The main components address specific aspects of payments including

Integration and maintenance of configuration of firewall to protect cardholder data.
It does not use vendor-supplied defaults. It uses other security measures and passwords.
It protects the stored data of cardholder
Provide Encryption of transmitted cardholder data across different networks.
Prevents and secures all systems against viruses and updates anti-virus software
Establish and control protected systems and applications.
Limit the access to cardholder data with business needs.
Provide identification and authentic access to the system and other components.
Limit the physical access to cardholder data.
Monitor and track all networks of cardholder data
Frequently test security measures and processes.
Uphold a policy that addresses information security for all personnel.

Why Is PCI Compliance Important

Frequent audits are on priority in maintaining PCI DSS compliance. They identify and protect the vulnerabilities against risks and protect them.

The frequency of audits varies from industry to industry and depends on various factors. These factors can include business size, number of transmissions, and distinct PCI compliance requirements

Businesses must prioritize and adhare to PCI compliance because.

Standards of PCI compliance make certain that cardholder data is encrypted, and secure and have low chances of data breaches.
It builds transparency and trust with customers and businesses to show they are committed to data security.
It reduces the chances of penalties and fines. The amount of fine ranges from5,000 to
5,000to100,000 per month depending on data violation severity.
It reduces data breaches and protects your business from costly damages.

Best Practices For Audit Frequency

The periodicity of PCI compliance audits depends on your business’s PCI compliance. The level and the specifications of PCI DSS requirements apply to you.

A breakdown below explains the best practices for frequency audits.

Annual Audits

It is the minimum requirement for most businesses. This is the PCI compliance Level 1. It must undergo and be conducted by a Qualified Security Assessor (QSA).

This aligns with the PCI compliance certification cycle. It reviews your security policies, procedures, and systems to ensure compliance with PCI DSS requirements.

To achieve PCI certification, businesses must accomplish a PCI compliance audit (for Level 1 businesses) A Self-Assessment Questionnaire (for Levels 2-4).

Quarterly Scans

The PCI Security Standards Council suggests quarterly vulnerability scans. They must conduct quarterly network scans using an Approved Scanning Vendor (ASV).

These scans identify vulnerabilities and weaknesses in your network. These vulnerabilities can be exploited by a hacker.

Continuous Monitoring

formal audits are conducted annually but continuous monitoring is becoming increasingly important.

It ensures ongoing PCI DSS compliance procedures and policies. They help in the protection of issues before they arise.

They provide regular risk assessments, insertion of testing, and updated security protocols.

Post-Incident Audits

After a security incident or changes in the system, an additional audit is important to ensure PCI compliance standards to check they still meet the requirement.

Audit Frequency By PCI Compliance Level

Organizations are categorized on the size and transaction volume of your business.

They are based on different merchant levels. The PCI DSS requirements depend on your PCI compliance level. The four PCI compliance levels breakdown include

PCI Level	Criteria/Annual Transactions	Audit Requirements
Level 1	Over 6 million are processed annually	At this level Annual on-site audit by a Qualified Security Assessor (QSA) Quarterly network scans by an Approved Scanning Vendor (ASV).
Level 2	1-6 million transactions annually	At this level Annual self-assessment and quarterly network scans
Level 3	20,000-1 million e-commerce transitions are processed annually.	At this level Annual self-assessment andquarterly network scans
Level 4	Less than 20,000 e-commerce transitions are processed annually	At this level of annual self-assessment, quarterly network scans (if applicable)

Components Of A PCI Compliance Audit

A thorough and continuous PCI compliance audit covers all the aspects of PCI DSS requirements.
