This white paper has thus far examined the risks and challenges associated with mobile computing, particularly in the context of PCI compliance, and some of the "best practices" that can be employed to mitigate those risks.

PCI DSS dictates the security requirements for the systems that process and store sensitive cardholder data in payment processes. Companies often overlook the fact that bits of this data can and do end up in unexpected places, posing a risk to the organization as well as the customers whose information might be compromised. The best way to mitigate that risk is to focus on protecting the data, regardless of the platform it is on.

The mobile platform in particular presents numerous challenges. The "disconnected" nature of the beast makes it difficult to extend the protections of the corporate network and enforce the policies and procedures that help to ensure a secure environment and data protection.
