In practice, the CISO must manage risks from insider threats, supply chain vulnerabilities, and targeted cyberattacks by prioritizing security controls and monitoring emerging threats. Their decisions influence how effectively an organization detects and responds to incidents, maintains secure configurations, and integrates security into business processes. Effective CISOs balance technical expertise with strategic oversight to reduce exposure across diverse attack surfaces.
