Just attended a PCI-DSS workshop organized by VISA, wow, sure was worth it.  Have read the PCI-DSS docs a number of times but the whole classroom experience was very valuable.

Some important items worth noting:

• The idea behind the PCI program is to “Render the credit card data unreadable”, they way you could accomplish is: encrypting, hashing, truncation.
• PCI DSS - Is the standard itself
• AIS - Is the enforcement program
• Data that can never be stored, unless you are a credit card issuer:
  • Mag-stripe data
  • CVV2
  • PIN/PIN Block
• As per the requirements, you must notify your acquirer of a possible breach within 24 hours
• PCI DSS has about 230 requirements
• PCI DSS is based on fundamental data security practices:
  1. Data controls
  2. Network controls
  3. System level controls
  4. Application controls (Code reviews, app testing)
  5. Policies
  6. Physical Controls
• VISA is moving PABP from “best Practices” into a formal security starndard managed by the PCI SSC as the Payment Application Data Security Standard (PA-DSS)
• PCI Security Standards Council, launched in September 2006, is a global forum for the ongoing development and enhancement of security standards for account data protections, including the PCI DSS
