A chief information security officer (CISO) is an IT executive who manages and oversees the cybersecurity needs of an organization. Job responsibilities include data and network security, security policy, and security strategy. Their duties involve security operations, cyber-risk and cyber intelligence, data loss prevention, fraud prevention, identity and access management, investigations, and governance. A chief information security officer needs an in-depth understanding of information security, solid comprehension of the organization’s overarching vision, and the ability to combine the two into an actionable strategy.
