DEFINITION of 'C-Suite'. A widely-used slang term used to collectively refer to a corporation's most important senior executives. C-Suite gets its name because top senior executives' titles tend to start with the letter C, for chief, as in chief executive officer, chief operating officer and chief information officer.
The mid and higher level titles include Information Security Manager, Security Manager (IT) and Chief Information Security Officer. As per the findings of the 2014 IT Skills and Salary survey conducted by Global Knowledge and Penton, CISM holds second position among the top 15 IT certifications for 2014. Information security is racing ahead of two of the most popular IT skills; project management and programming.
