Organizations should conduct an external audit at least once every two years or whenever it's requested by competent authority, as mandated by applicable laws and regulations.
Audits are conducted by cybersecurity auditors, who are responsible for preparing a report on the audit findings. Organizations should note that some laws and regulations may require auditors to hold specific certifications, e.g. national cybersecurity audit security certificate or audit has to be done by specific authority.
Organizations are required to submit the report to the competent authority responsible for implementing cybersecurity requirements immediately upon receipt, if mandated by laws and regulations.
