Following PCI Security Standards Council rules is essential when you process card payments, but compliance alone isn't enough. Certain business practices significantly increase your vulnerability to data breaches, while strategic security measures can dramatically reduce your risk and protect both your customers and your business.
Essential steps to reduce your risk:
1. Eliminate unnecessary card data storage
- Never store card data unless absolutely required for your business operations
- Use tokenization for repeat payments instead of storing actual card numbers
- Permanently delete any stored CVV codes, full magnetic stripe data, or PINs
- Regularly audit and purge any unnecessary payment data from all systems
2. Secure your payment processing environment
- Use only PCI-certified payment terminals and software
- Isolate payment systems on separate networks from other business operations
- Implement strong access controls limiting who can access payment data
- Keep all payment software and systems updated with latest security patches
3. Train your staff on security best practices
- Educate employees about social engineering and phishing attacks
- Train staff never to store, email, or write down complete card information
- Establish clear procedures for handling payment data securely
- Regularly test staff knowledge of security policies and procedures
4. Monitor and detect suspicious activity
- Implement logging and monitoring for all payment system access
- Set up alerts for unusual transaction patterns or system access
- Regularly review access logs and transaction reports for anomalies
- Establish incident response procedures for suspected security breaches
5. Secure your broader IT environment
- Use strong, unique passwords and multi-factor authentication
- Keep all business software and operating systems updated
- Install and maintain current antivirus and anti-malware protection
- Regularly backup critical data and test restoration procedures
6. Work with compliant service providers
- Verify all third-party providers handling card data are PCI compliant
- Use reputable payment processors with strong security track records
- Ensure cloud services and hosting providers meet security requirements
- Regularly review and update vendor security agreements
7. Red flags that increase your breach risk
- Card data stored unnecessarily in multiple systems or locations
- Staff with excessive access to payment systems and data
- Outdated software or systems with known security vulnerabilities
- Weak passwords or shared accounts for accessing payment systems
- No monitoring or logging of payment system access and activities
- Third-party providers with unclear or expired security certifications
- Manual processes that increase handling of sensitive payment data
The bottom line
Data breaches can destroy businesses through fines, lawsuits, and lost customer trust. The most effective protection combines eliminating unnecessary data storage, securing your payment environment, and maintaining strong ongoing security practices.
