The establishment of a security perimeter and of internal security requirements with the goal of defending a network against cyberattacks, intrusions and other violations. A CND is defined by a security policy and can be stress tested using vulnerability assessment and penetration testing measures.
Computer network operations (CNO) is a broad term that has both military and civilian application. Conventional wisdom is that information is power, and more and more of the information necessary to make decisions is digitized and conveyed over an ever-expanding network of computers and other electronic devices. Computer network operations are deliberate actions taken to leverage and optimize these networks to improve human endeavor and enterprise or, in warfare, to gain information superiority and deny the enemy this enabling capability.
