• CISOs need to focus on building a defendable cybersecurity program with key elements.

The article discusses the challenges that modern CISOs face in navigating the new SEC cyber regulations. CISOs are now required to demonstrate and attest to the fidelity of their cybersecurity program within a short timeframe of four days in the event of a breach. The outdated method of relying on Indicator of Compromise (IOC)-based threat intelligence is no longer effective, and CISOs need to shift towards a proactive planning approach for defensive controls.

The article also highlights the internal challenges that CISOs may face, such as conflicting opinions from stakeholders and potential implications of the Sarbanes-Oxley Act on whistleblower protections. CISOs are urged to build a well-reasoned and defendable cybersecurity program that focuses on defining material risk, identifying threats, assessing threats, and managing threats and vulnerabilities effectively.

By adopting aggressive changes and leveraging TTP-based threat intelligence, CISOs can better navigate the new SEC regulations and improve the cybersecurity industry as a whole. These proactive measures will help CISOs stay ahead of evolving threats and protect their organizations from potential breaches.
