Cybersecurity, also known as computer security, digital security, or information technology security, refers to the practice of protecting computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. Cybersecurity is of high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, elections, and finance. Cybersecurity is a wide field covering several disciplines and can be divided into seven main pillars: network security, application security, endpoint security, data security, identity management, security operations, and cloud security. The threats countered by cybersecurity are three-fold: confidentiality, integrity, and availability of a network, also known as the CIA triad. Cybersecurity measures include administrative, physical, and technical security measures to ensure the confidentiality, integrity, and availability of a network. A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe, and a unified threat management system can automate integrations across select security products and accelerate key security operations functions.
