What is Cyber Security? Cyber security refers generally to the ability to control access to  networked systems and the information they contain.  – Where cyber security controls are effective is known as cyberspace and is  considered a reliable, resilient, and trustworthy digital infrastructure.  – Where cyber security controls are absent, incomplete, or poorly designed,  cyberspace is considered the wild west of the digital age. Whether a system is a physical facility or a collection of cyberspace  components, the role of a security professional assigned to that  system is to plan for potential attack and prepare for its  consequences. 2
