Security
Security is protection from, or resilience against, potential harm (or other unwanted coercion). Beneficiaries (technically referents) of security may be persons and social groups, objects and institutions, ecosystems, or any other entity or phenomenon vulnerable to unwanted change. Security mostly refers to protection from hostile forces, but it has a wide range of other senses: for example, as the absence of harm (e.g., freedom from want); as the presence of an essential good (e.g., food security); as resilience against potential damage or harm (e.g. secure foundations); as secrecy (e.g., a secure telephone line); as containment (e.g., a secure room or cell); and as a state of mind (e.g., emotional security). Security is both a feeling and a state of reality. One might feel secure when one is not actually so; or might feel insecure despite being safe. This distinction is usually not very clear to express in the English language. The term is also used to refer to acts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Security
Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It consists of the protection of computer software, systems and computer network, networks from Threat (security), threats that can lead to unauthorized information disclosure, theft or damage to computer hardware, hardware, software, or Data (computing), data, as well as from the disruption or misdirection of the Service (economics), services they provide. The significance of the field stems from the expanded reliance on computer systems, the Internet, and wireless network standards. Its importance is further amplified by the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity has emerged as one of the most significant new challenges facing the contemporary world, due to both the complexity of information systems and the societi ...

Food Security
Food security is the state of having reliable access to a sufficient quantity of affordable, healthy Human food, food. The availability of food for people of any class, gender, ethnicity, or religion is another element of food protection. Similarly, household food security is considered to exist when all the members of a family have consistent access to enough food for an active, healthy life. Food-secure individuals do not live in hunger or fear of starvation. Food security includes resilience to future disruptions of food supply. Such a disruption could occur due to various risk factors such as droughts and floods, shipping disruptions, fuel shortages, economic instability, and wars. Food insecurity is the opposite of food security: a state where there is only limited or uncertain availability of suitable food. The concept of food security has evolved over time. The four pillars of food security include availability, access, utilization, and stability. In addition, there are tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Security Guard
A security guard (also known as a security inspector, security officer, factory guard, or protective agent) is a person employed by a government or private party to protect the employing party's assets (property, people, equipment, money, etc.) from a variety of hazards (such as crime, waste, damages, unsafe worker behavior, etc.) by enforcing preventative measures. Security guards do this by maintaining a high-visibility presence to deter illegal and inappropriate actions, looking (either directly through patrols, or indirectly by monitoring alarm systems or video surveillance cameras) for signs of crime or other hazards (such as a fire), taking action to minimize damage (such as warning and escorting trespassers off property), and reporting any incidents to their clients and emergency services (such as the police or emergency medical services), as appropriate. Security officers are generally uniformed to represent their lawful authority to protect private property. Securit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Security Police
Security police usually describes a law enforcement agency which focuses primarily on providing security and law enforcement services to particular areas or specific properties. They may be employed by governmental, public, or private institutions. Security police are generally considered distinct from security guards as security police personnel typically hold some level of law enforcement authority. The exact powers held by security police vary widely between jurisdictions. Examples of these types of agencies include the United States' DoD Police and FBI Police, the Indian Central Industrial Security Force, and the British Civil Nuclear Constabulary. In some countries, ''security police'' is the name given to the secret security and intelligence services charged with protecting the state at the highest level, including responsibilities such as personal protection of the head of state, counter-espionage, and anti-terrorism. Examples of these agencies include the Japanese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Security
Physical security describes security measures that are designed to deny unauthorized access to facilities, equipment, and resources and to protect personnel and property from damage or harm (such as espionage, theft, or terrorist attacks). Physical security involves the use of multiple layers of interdependent systems that can include CCTV surveillance, security guards, protective barriers, locks, access control, perimeter intrusion detection, deterrent systems, fire protection, and other systems designed to protect persons and property. Overview Physical security systems for protected facilities can be intended to: * deter potential intruders (e.g. warning signs, security lighting); * detect intrusions, and identify, monitor and record intruders (e.g. security alarms, access control and CCTV systems); * trigger appropriate incident responses (e.g. by security guards and police); * delay or prevent hostile movements (e.g. door reinforcements, grilles); * protect the as ...

Antivirus Software
Antivirus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware. Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other malware, antivirus software started to protect against other computer threats. Some products also include protection from malicious URLs, spam, and phishing. History 1971–1980 period (pre-antivirus days) The first known computer virus appeared in 1971 and was dubbed the " Creeper virus". This computer virus infected Digital Equipment Corporation's ( DEC) PDP-10 mainframe computers running the TENEX operating system.From the first email to the first YouTube video: a d ...

Closed-circuit Television
Closed-circuit television (CCTV), also known as video surveillance, is the use of closed-circuit television cameras to transmit a signal to a specific place on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point, point-to-multipoint (P2MP), or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring ( videotelephony is seldom called "CCTV"). The deployment of this technology has facilitated significant growth in state surveillance, a substantial rise in the methods of advanced social monitoring and control, and a host of crime prevention measures throughout the world. Though surveillance of the public using CCTV is common in many areas around the world, video surveillance has generated significant debate about balancing its us ...

Security Company
A private security company is a business entity which provides armed or unarmed security services and expertise to clients in the private or public sectors. Overview Private security companies are defined by the U.S. Bureau of Labor Statistics as companies primarily engaged in providing guard and patrol services, such as bodyguard, guard dog, parking security and security guard services. Many of them will even provide advanced special operations services if the client demands it. Examples of services provided by these companies include the prevention of unauthorized activity or entry, traffic regulation, access control, and fire and theft prevention and detection. These services can be broadly described as the protection of personnel and/or assets. Other security services such as roving patrol, bodyguard, and guard dog services are also included, but are a very small portion of the industry. During the COVID-19 pandemic, some security companies engaged in vaccine supply chain s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Security Agency
A security agency is a governmental organization that conducts intelligence activities for the internal security of a state. They are the domestic cousins of foreign intelligence agencies, and typically conduct counterintelligence to thwart other countries' foreign intelligence efforts. For example, the United States Federal Bureau of Investigation (FBI) is an internal intelligence, security and law enforcement agency, while the Central Intelligence Agency (CIA) is an external intelligence service, which deals primarily with intelligence collection overseas. A similar relationship exists in Britain between MI5 and MI6. The distinction, or overlap, between security agencies, national police, and gendarmerie organizations varies by country. For example, in the United States, one organization, the FBI, is a national police, an internal security agency, and a counterintelligence agency. In other countries, separate agencies exist, although the nature of their work causes them to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resilience (organizational)
Business continuity may be defined as "the capability of an organization to continue the delivery of products or services at pre-defined acceptable levels following a disruptive incident", and business continuity planning (or business continuity and resiliency planning) is the process of creating systems of prevention and recovery to deal with potential threats to a company. In addition to prevention, the goal is to enable ongoing operations before and during execution of disaster recovery. Business continuity is the intended outcome of proper execution of both business continuity planning and disaster recovery. Several business continuity standards have been published by various standards bodies to assist in checklisting ongoing planning tasks. Business continuity requires a top-down approach to identify an organisation's minimum requirements to ensure its viability as an entity. An organization's resistance to failure is "the ability ... to withstand changes in its environmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotional Security
Insecurity is the emotion associated with a lack of confidence within oneself. It is often associated with feelings of fear and uncertainty, especially surrounding one's abilities. The word was originally used in the psychological sense in the year 1917. It has been observed in both adults and children. The word is also associated with attachment styles. Characteristics Abraham Maslow described an insecure person as a person who "perceives the world as a threatening jungle and most human beings as dangerous and selfish; feels like a rejected and isolated person, anxious and hostile; is generally pessimistic and unhappy; shows signs of tension and conflict, tends to turn inward; is troubled by guilt-feelings, has one or another disturbance of self-esteem; tends to be neurotic; and is generally selfish and egocentric." He viewed in every insecure person a continual, never dying, longing for security. A person's capacity for deep thought, understanding others' perspectives, and awa ...

Remote Guarding
Remote guarding is a proactive security system combining CCTV video cameras, video analytics, alarms, monitoring centers and security agents. Potential threats are first spotted by cameras and analyzed in real-time by software algorithms based on predefined criteria. Once an event has been identified by the software, a security officer located in a remote center is then alerted to analyze the threat and take appropriate action immediately to prevent or minimize damage from occurring. These actions can include a verbal warning to the perpetrator via two-way radio from the center or reporting the event to local law enforcement. Remote guarding adds a layer of human verification to automated security systems that results in reducing false alarms to almost 0% by having trained agents review each alert before taking action. This service along with changes to how the alarm industry handles alarms, such as second call verification, continue to reduce the false alarm burden on local la ...
