Meeting PCI DSS Compliance Standards
Prioritize organizational controls, planning, leadership commitment and basic infrastructure tools such as firewalls, anti-virus, password management, data storage and encryption, identity management, etc. Once these controls and solutions have been implemented, working closely with the Information Technology team to monitor them is vital. This may include vulnerability scanning, monitoring for configuration changes, intrusion detection, etc.
Implement a Firewall
Install and maintain a firewall configuration to protect cardholder data. Setup firewall and zoning and monitor the configuration for unauthorized changes.
Avoid Vendor Defaults
Don't use vendor defaults for system passwords and other security parameters. Change default passwords and monitor the configuration for critical infrastructure.
Use a secure data storage repository, with around-the-clock monitoring for attacks and leaks.
Leverage Encryption
Encrypt transmission of cardholder data across open, public networks. Encrypt and monitor systems that contain Personal Area Network (PAN).
Implement Anti-Virus
Utilize and regularly update anti-virus software or programs through automated patch deployment.
Secure Your Applications
Develop and maintain secure systems and applications and use a 24-7 logging tool to track external and internal vulnerabilities.
Restrict Access
Operate on a "need to know" basis. Limiting who has access to critical data and leveraging identity management solutions, such as Azure Active Directory, to manage users.
Use Employee Identifiers
Assign a unique ID to each individual who has computer access that can track behavior anomalies and risks.
Lock It Up
If applicable, restrict physical access to cardholder data.
Use a Security Information and Event Management (SIEM)
Track and monitor all access to network resources and cardholder data through a log management software. You'll need a solution that incorporates auditing and forensics, external vulnerability scans and intrusion detection.
Test Your Systems
Regularly test security systems and processes. Collect logs from intrusion detection and prevention systems to validate compliance.
Put It in Writing
Maintain a policy that addresses information security for all personnel. Create a team and host routine managed security training for users.
