PCI Compliant Server Hosting

The PCI DSS comprises six security goals with 12 requirements in total:

• Build and maintain a secure network.
  • Install and maintain a firewall configuration to protect cardholder data.
  • Do not use vendor-supplied defaults for system passwords and other security parameters.
• Protect Cardholder Data
  • Protect stored cardholder data.
  • Encrypt transmission of cardholder data across open, public networks.
• Maintain a Vulnerability Management Program
  • Use and regularly update anti-virus software or programs.
  • Develop and maintain secure systems and applications.
• Implement Strong Access Control Measures
  • Restrict access to cardholder data by business need-to-know.
  • Assign a unique ID to each person with computer access.
  • Restrict physical access to cardholder data.
• Regularly Monitor and Test Networks
  • Track and monitor all access to network resources and cardholder data.
  • Regularly test security systems and processes.
• Maintain an Information Security Policy
  • Maintain a policy that addresses information security for employees and contractors.

To comply with the PCI DSS, your business’s infrastructure, networks, processes, and software must comply with the goals and standards of the credit card industry. Additionally, businesses must be able to prove that they are compliant.

For most businesses, that means completing a Self-Assessment Questionnaire, which includes an Attestation of Compliance. Larger companies—those that process more than 6 million transactions a year—must complete a third-party audit with a qualified security assessor (QSA).

Merchants are divided into levels according to how many credit card transactions they process each year.

• Level 1 – Over 6 million transactions per year
• Level 2 – Between 1 and 6 million transactions per year
• Level 3 – Between 20,000 and 1 million transactions per year
• Level 4 – Less than 20,000 transactions per year

Although these criteria are accurate, individual credit card companies may apply alternative criteria that affect a merchant's level, so be sure to look into the rules that apply to your business.

A merchant's level determines the actions they must take to demonstrate compliance. Level 2,3, 4 merchants should complete an Annual Self-Assessment Questionnaire and a quarterly network scan by an Approved Scan Vendor (ASV). Level 1 merchants are required to undergo an Annual Report on Compliance (ROC) by a Qualified Security Advisor (QSA).
