Remember – to meet Payment Card Industry Data Security Standard (PCI DSS) requirements you must have both a software and hardware firewall. But it’s not enough to just own them. They must be configured properly to prevent data from accessing (or leaving) your network when it’s not supposed to.
Here are some tips for proper configuration:
- Work with your IT service provider to configure firewalls and routers
- Google your firewall manufacturer to find helpful ‘how to’ articles
- Quarterly test your network with internal and external network vulnerability scans
