Let us now try to understand the meaning of the word ‘security’. ‘Security’ is derived from the Latin word secures, which means ‘free from danger’ or ‘safe’. Thus, security can be defined as freedom from exposure to danger; a feeling of safety and certainty; freedom from anxiety; a means of protection or arrangement to secure (safeguard) a property against theft, intrusion, pilferage or damage; and rendering living beings safe. In a rapidly changing social and technological environment, understanding security aspects and actions is important for improving security. The basic objective of providing security is to prevent crime against persons, property and proprietary information. Security provides a safe and danger-free environment, so that people can conduct their daily chores and businesses without fear.
