Security refers to the measures and protocols in place to protect individuals, systems, or assets from harm, loss, or unauthorized access. The concept is multifaceted and can be applied across a range of contexts, from physical security, which involves safeguarding people and property through surveillance, locks, and guards, to cybersecurity, which focuses on protecting digital data and networks from unauthorized intrusion or cyberattacks. In financial terms, security can also refer to investment instruments like stocks and bonds. Regardless of the context, the primary objective of security is to manage risk and create an environment that is as free from danger or threat as possible. As technology advances and the world becomes more interconnected, the challenges around security grow increasingly complex, involving not just technical measures but also considerations of policy, human behavior, and ethics. Consequently, the concept of security has become a central concern for individuals, organizations, and governments, necessitating ongoing efforts to adapt and respond to emerging threats.
