How To Get Four Levels of PCI Compliance
There are four levels of PCI compliance, each with its own set of requirements. Level 1
is the highest level of compliance and requires the most stringent security measures.
To be compliant at this level, businesses must:
●
●
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
To achieve Level 2 compliance, businesses must:
●
●
●
Meet all the requirements of Level 1
Implement strong access control measures
Regularly monitor and test networks
Level 3 compliance requires that businesses:
●
●
●
Meet all the requirements of Levels 1 and 2
Maintain a vulnerability management program
Develop and maintain secure systems and applications
The highest level of PCI compliance, Level 4, is reserved for businesses that process
very large volumes of transactions. To be compliant at this level, businesses must:
●
●
●
Meet all the requirements of Levels 1, 2, and 3
Conduct quarterly network scans by an approved scanning vendor
Implement additional security measures to protect cardholder data
Achieving PCI compliance can be a complex and time-consuming process, but it is
essential for businesses that accept credit and debit cards. By following the guidelines
set forth by the PCI Security Standards Council, businesses can protect themselves
and their customers from fraud and data breaches.
