Security refers to the measures taken to protect a person, organization, or system from harm, damage, or unauthorized access. It encompasses a range of practices and technologies that aim to safeguard assets—such as information, physical property, and individuals—from threats like theft, vandalism, cyber attacks, and natural disasters.
In a broader context, security can be segmented into various areas, including physical security (protection of physical assets and facilities), information security (safeguarding data and information systems), cybersecurity (protection against digital attacks), and personal security (protection of individuals).
Effective security requires a combination of policies, procedures, tools, and techniques tailored to identify vulnerabilities, manage risks, and respond to incidents. The ultimate goal is to ensure the integrity, confidentiality, and availability of resources, fostering a safe and secure environment for users and entities.
