Final answer:
Security terms like physical security, personal security, surveillance, and access control play crucial roles in protecting individuals, data, and infrastructure.
Step-by-step explanation:
Physical security refers to the protection of people, property, and physical assets from actions and events that could cause damage or loss. It includes measures such as locks, security guards, and alarm systems designed to protect individuals and property.
Personal security is the level of resilience against potential threats to an individual's safety. It can involve steps taken to ensure one's personal safety such as personal alarms, security protocols, and self-defense techniques.
Surveillance is the monitoring of behavior, activities, or information for information gathering, influencing, managing, or directing. This can include the use of CCTV cameras, wiretaps, and online tracking.
Access control is a method of guaranteeing that users are who they say they are and that they have the appropriate access to company data. It involves authentication and authorization systems, such as passwords and biometric scans, to ensure that access to sensitive information is carefully controlled.
A critical aspect of national security is political security which encompasses the stability of the social order and includes diplomacy and negotiation processes.
The concept of national security has evolved to include not only military power but also economic security, energy security, and environmental security. A broad interpretation of national security also takes into account the presence of non-state actors, such as violent non-state actors, narcotic cartels, and the impact of natural disasters.
Amidst rising online interaction, the issues of online privacy and security have become more pressing, with individuals and organizations alike needing to implement safeguards, such as two-factor authentication and robust data protection measures.
