Security is the protection of assets, including physical property, information, and people, from damage or loss caused by external forces. The term security covers a broad range of activities designed to prevent disruptions such as crime, natural disasters, cyber-attacks, and espionage. It encompasses procedures, technological tools, and measures aimed at protecting entities—from one-person businesses to large corporations— against threats that can cause harm. Security’s main goals are to reduce vulnerability and provide assurance of safety.
