Chief security officer
The title chief security officer (CSO) was first used principally inside the information technology function to designate the person responsible for IT security. At many companies, the term CSO is still used in this way. CISO, for chief information security officer, is perhaps a more accurate description of this position, and today the CISO title is becoming more prevalent for leaders with an exclusive information security focus.
The CSO title is also used at some companies to describe the leader of the "corporate security" function, which includes the physical security and safety of employees, facilities, and assets. More commonly, this person holds a title such as Vice President or Director of Corporate Security. Historically, corporate security and information security have been handled by separate (and sometimes feuding) departments.
Increasingly, chief cecurity officer means what it sounds like: The CSO is the executive responsible for the organization's entire security posture, both physical and digital. CSOs also frequently own or participate closely in related areas such as business continuity planning, loss prevention and fraud prevention, and privacy.
Several forces are driving this trend to combine all forms of security under a single organizational umbrella. At a tactical level, technology is being infused into physical security tools, which are increasingly database-driven and network-delivered. At a strategic level, CSOs and corporate boards, motivated in part by regulations such as the Sarbanes-Oxley Act, desire an enterprise-wide view of operational risk. And at a practical level, CSOs say a cohesively managed security function can deliver better security at lower cost.
