Evolution of IT Security

You have been a system administrator for 15 years, and you have seen your role evolve and change. This evolution of information technology (IT) has resulted in IT security being a top priority in Enterprise support. When you first started in this field, security was merely checking virus updates and making sure you put patches on your computers to protect the system from intruders.
