One of the main things you can do for PCI compliance purposes is to establish a secure firewall. You can use a firewall to protect cardholder data and ensure no unauthorized parties can try to access the content.
This part of PCI compliance can work on your POS system with a few steps:
- You must position your firewalls to where only necessary traffic can enter. This traffic may come from authorized users who want to collect information from consenting parties. You can plan your POS system to include many users who can get access to various systems.
- A “deny all” rule is necessary for all other forms of traffic. Anything that has not entered without the support of an authorized user will be blocked.
- A secure zone for card storage purposes will be necessary. The zone can be separate from other parts of your POS system, ensuring the data won’t be accessed in other spaces.
- Additional firewalls may work in between wireless networks and your common desktop environment or CDE.
You can use software and hardware-based firewalls alike. A software-based system works for your current operating system, while a hardware one focuses on all possible transactions you might complete in your work. Having both of these at once can add further protection to ensure your work is managed well.
Your PCI compliance plans will work well if you have a suitable firewall system. Your firewall ensures there’s a proper amount of access between all parties, ensuring nothing rough happens with your data.
