PCI DSS 4.0 12.10.3: 12.10.3 Incident response personnel available 24/7
The entity must name specific personnel who are reachable around the clock (24/7) to handle any suspected or confirmed security incident. The guidance explains this is often arranged through a response team working a rotating schedule, made up of permanently assigned core members and on-demand specialists called in according to their expertise and the nature of the incident, so that someone trained and familiar with the plan is always on hand. Customized approach objective: incidents receive an immediate response where appropriate.
This control maps to 39 controls across 19 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
