Keep working relationships with regulators, law enforcement and CERTs before you need them.
What else in your programme already covers this
This control maps to 65 controls across 33 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
NIST-CSF-GV.RM-05 Lines of communication across the organization are established for cybersecurity risks, including risks from suppliers and other third parties
NIST-CSF-RC.CO-04 Public updates on incident recovery are shared using approved methods and messaging
NIST-CSF-RS.CO-02 Internal and external stakeholders are notified of incidents
NIST-CSF-RS.CO-03 Information is shared with designated internal and external stakeholders
NIST-CSF-RS.MA-01 The incident response plan is executed in coordination with relevant third parties once an incident is declared
NIST800-PM-15 Security and Privacy Groups and Associations. Establish and institutionalize contact with selected groups and associations within the security and privacy communities: To facilitate ongoing security and privacy education and training for organizational personnel; To
NIST800-SI-5 Security alerts, advisories, and directives

You are reading one control. How much of ISO 27001:2022 have you already done?
ISO 27001:2022 5.5 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of ISO 27001:2022 your existing evidence covers. Hold NIST SP 800-53 Rev 5 and 79 of 93 ISO 27001:2022 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 170 were rejected on the NIST SP 800-53 Rev 5 pair alone.
