CISOs should focus on top cybersecurity frameworks: NIST CSF 2.0 for strategy, ISO 27001 for ISMS, CIS Controls v8.1 for safeguards, NIST 800-53 for controls, SOC 2 for assurance, PCI DSS v4.0.1 for cardholder data, MITRE ATT&CK for threat defense, CSA CCM v4 for cloud, IEC 62443 for OT, and NERC CIP for the power grid. Current frameworks ensure compliance and preparedness against regulations, improving overall security postures.
