The efforts to design, implement, and maintain security for an organization’s network, which is connected to the Internet. It is a combination of logical/technical-, physical- and personnel-focused countermeasures, safeguards and security controls. An organization’s cybersecurity should be defined in a security policy, verified through evaluation techniques (such as vulnerability assessment and penetration testing) and revised, updated and improved over time as the organization evolves and as new threats are discovered.
