<p>The CISO is part of a business’s C-level executive suite. CISOs ensure information resources and technologies are effectively protected. They oversee the development, implementation and enforcement of security policies. Depending on the organization’s structure, they often report to the chief information officer (<a href=”https://www.techtarget.com/searchcio/definition/CIO”>CIO</a>) or even directly to the board. The CISO might also work alongside the CIO to procure cybersecurity products and services, and to manage <a href=”https://www.techtarget.com/searchdisasterrecovery/definition/disaster-recovery”>disaster recovery</a> and <a href=”https://www.techtarget.com/searchdisasterrecovery/definition/business-continuity-action-plan”>business continuity plans</a>.</p>
