If you're doing business and collecting payments via credit card, debit card, or other e-commerce options that allow you to store and/or transmit cardholder data, you are subject to PCI DSS compliance regulations.
In an attempt to reduce credit card fraud, the Payment Card Industry Security Standards Council developed an information security standard for those with access to consumers' transactions and card numbers. This standard continues to evolve, and is now labeled PCI DSS 2.0. While the compliance verification process isn't formal for all organizations, they all must meet the standard to manage liability in case of credit card fraud.
Linoma Software [now HelpSystems] has published a new white paper entitled PCI DSS Compliance with Managed File Transfer that reviews the requirements for PCI DSS 2.0, and explains what role implementing a managed file transfer solution can have in meeting several aspects of the regulations, especially the protection of cardholder data.
