We are now integrating encryption into a corporate infrastructure and it made me think about payments and PCI audits. PCI stands for Payment Card Industry. Anyone who got close enough to e-commerce, or card payments knows what a burden it is on running a business.
Sooo, I have spent some time this week thinking about architectures for “technical security systems”. I could say “cryptography” straight away, I guess. Thinking about protecting sensitive data that may be subject of independent audits.
The scope of PCI audits is given by storage and processing of credit card numbers and PINs (in case of Chip&PIN systems). Once you experience the pain, you definitely want to get “out of scope”. This is true for merchants just as banks.
