The Central Bank of Russia has published new requirements for the hardware and software used in socially important card payment systems, setting updated information security expectations for the devices embedded in these systems. The requirements cover hardware security modules built into payment system infrastructure, payment devices with a kernel, ATMs and payment cards. They establish parameters for developers, replace the approaches in place since 2020, and reflect the regulator’s newer measures to protect data in money transfers, including with the stated aim of supporting more efficient import substitution.
