Requirement 12.3 covers targeted risk analyses for requirements with flexible frequencies or the customized approach, plus yearly reviews of cryptographic cipher suites and protocols and of hardware and software technologies in use.
Requirement 12.4 makes PCI DSS compliance a managed program: for service providers, executive accountability with a charter, and quarterly reviews confirming personnel are performing security tasks such as log reviews and change management.

Requirement 12.10 requires an incident response plan that is tested yearly, staffed 24/7, covers alerts from security monitoring systems, evolves from lessons learned, and includes procedures for PAN found where it should not be.
