All organizations—regardless of size—need to adopt a heightened posture when it comes to cybersecurity and protecting their most critical assets. Sophisticated cyber actors and nation-states exploit vulnerabilities to steal information and money and are developing capabilities to disrupt, destroy, or threaten the delivery of essential services. Implementing organizational cybersecurity best practices requires coordination across the organization from leadership to IT to communications and human resources. From governance to updating technology, cybersecurity requires a holistic approach that often starts with leadership directive. Protecting the cyber space is an essential aspect of business operations and must be integrated at all levels.
