In its broadest definition, chief security officer may refer to the person chiefly responsible for an organization's information security, as well as its so-called “corporate security” — that is, the physical security and safety of employees, facilities and assets.

CISOs are responsible for tasks such as designing and implementing an organization's security program, working with outside security vendors, training employees on security practices, and so forth. CSOs, or Chief Security Officers, are responsible for securing people, products, and processes.
