What is a CISO (chief information security officer)?

The CISO (chief information security officer) is a senior-level executive responsible for developing and implementing an information security program, which includes procedures and policies designed to protect enterprise communications, systems and assets from both internal and external threats.

In an organization, the CISO ensures information resources and technologies are effectively protected. CISOs oversee the development, implementation and enforcement of security policies. The CISO might also work alongside the chief information officer to procure cybersecurity products and services and to manage disaster recovery and business continuity plans.

The chief information security officer might also be referred to as the chief security architect, the security manager, the corporate security officer or the information security manager, depending on the company’s structure and existing titles. When the CISO is also responsible for the overall corporate security of the company — which includes its employees and facilities — they might simply be called the chief security officer.

What does a CISO do?

In addition to responding to data breaches and other security incidents, the CISO is tasked with anticipating, assessing and actively managing new and potential cyber threats. The CISO must work with other executives across different departments to align security initiatives with broader business objectives and mitigate the security risks various threats pose to the organization’s mission and goals.

CISOs have a variety of roles and responsibilities surrounding an organization’s security implementations.

The chief information security officer’s roles and responsibilities include the following:

• Conducting employee security awareness training.
• Developing secure business and communication practices.
• Identifying security objectives and metrics.
• Choosing and purchasing security products from vendors.
• Ensuring that the company is in regulatory compliance with the rules of relevant bodies.
• Enforcing adherence to data security practices.
• Ensuring the company’s data privacy is secure.
• Managing the computer security incident response team.
• Conducting electronic discovery and digital forensic investigations.
• Developing cyber resiliency and disaster recovery plans.
• Determining if security strategies are worth the investment financially.
