Authorized
Authorization or authorisation (see American and British English spelling differences#-ise, -ize (-isation, -ization), spelling differences), in information security, computer security and identity management, IAM (Identity and Access Management), is the function of specifying rights/privileges for accessing resources, in most cases through an access policy, and then deciding whether a particular ''subject'' has privilege to access a particular ''resource''. Examples of ''subjects'' include human users, computer software and other Computer hardware, hardware on the computer. Examples of ''resources'' include individual files or an item's data, computer programs, computer Computer hardware, devices and functionality provided by computer applications. For example, user accounts for human resources staff are typically configured with authorization for accessing employee records. Authorization is closely related to access control, which is what enforces the authorization policy by d ... [...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 ...

Information Security
Information security is the practice of protecting information by mitigating information risks. It is part of information risk management. It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, Data breach, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information. It also involves actions intended to reduce the adverse impacts of such incidents. Protected information may take any form, e.g., electronic or physical, tangible (e.g., Document, paperwork), or intangible (e.g., knowledge). Information security's primary focus is the balanced protection of data confidentiality, data integrity, integrity, and data availability, availability (also known as the 'CIA' triad) while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process. To stand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Access Control
In physical security and information security, access control (AC) is the action of deciding whether a subject should be granted or denied access to an object (for example, a place or a resource). The act of ''accessing'' may mean consuming, entering, or using. It is often used interchangeably with authorization, although the authorization may be granted well in advance of the access control decision. Access control on digital platforms is also termed admission control. The protection of external databases is essential to preserve digital security. Access control is considered to be a significant aspect of privacy that should be further studied. Access control policy (also access policy) is part of an organization’s security policy. In order to verify the access control policy, organizations use an access control model. General security policies require designing or selecting appropriate security controls to satisfy an organization's risk appetite - access policies ...

Authorization Hold
Authorization hold (also card authorization, preauthorization, or preauth) is a service offered by credit and debit card providers whereby the provider puts a hold of the amount approved by the cardholder, reducing the balance of available funds until the merchant clears the transaction (also called settlement), after the transaction is completed or aborted, or because the hold expires. In the case of debit cards, authorization holds can fall off the account, thus rendering the balance available again, anywhere from one to eight business days after the transaction date, depending on the bank's policy. In the case of credit cards, holds may last as long as thirty days, depending on the issuing bank. Transactions may be withdrawn but in most cases, especially with smaller banks, will not show up as a deposit on the cardholder's bank statement but will instead be directly added to the available balance automatically due to it only being a “temporary charge”. The usual reason fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Role-based Access Control
In computer systems security, role-based access control (RBAC) or role-based security is an approach to restricting system access to authorized users, and to implementing mandatory access control (MAC) or discretionary access control, discretionary access control (DAC). Role-based access control is a policy-neutral access control mechanism defined around roles and privileges. The components of RBAC such as role-permissions, user-role and role-role relationships make it simple to perform user assignments. A study by NIST has demonstrated that RBAC addresses many needs of commercial and government organizations. RBAC can be used to facilitate administration of security in large organizations with hundreds of users and thousands of permissions. Although RBAC is different from MAC and DAC access control frameworks, it can enforce these policies without any complication. Design Within an organization, role (computer science), roles are created for various job functions. The permiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Identity Management
Identity and access management (IAM or IdAM) or Identity management (IdM), is a framework of policies and technologies to ensure that the right users (that are part of the ecosystem connected to or within an enterprise) have the appropriate access to technology resources. IAM systems fall under the overarching umbrellas of IT security and data management. Identity and access management systems not only identify, authenticate, and control access for individuals who will be utilizing IT resources but also the hardware and applications employees need to access. The terms "identity management" (IdM) and "identity and access management" are used interchangeably in the area of identity access management. Identity-management systems, products, applications and platforms manage identifying and ancillary data about entities that include individuals, computer-related hardware, and software applications. IdM covers issues such as how users gain an identity, the roles, and sometimes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Network
A computer network is a collection of communicating computers and other devices, such as printers and smart phones. In order to communicate, the computers and devices must be connected by wired media like copper cables, optical fibers, or by wireless communication. The devices may be connected in a variety of network topologies. In order to communicate over the network, computers use agreed-on rules, called communication protocols, over whatever medium is used. The computer network can include personal computers, Server (computing), servers, networking hardware, or other specialized or general-purpose Host (network), hosts. They are identified by network addresses and may have hostnames. Hostnames serve as memorable labels for the nodes and are rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the tr ...

Authentication
Authentication (from ''authentikos'', "real, genuine", from αὐθέντης ''authentes'', "author") is the act of proving an Logical assertion, assertion, such as the Digital identity, identity of a computer system user. In contrast with identification, the act of indicating a person or thing's identity, authentication is the process of verifying that identity. Authentication is relevant to multiple fields. In art, antiques, and anthropology, a common problem is verifying that a given artifact was produced by a certain person, or in a certain place (i.e. to assert that it is not counterfeit), or in a given period of history (e.g. by determining the age via carbon dating). In computer science, verifying a user's identity is often required to allow access to confidential data or systems. It might involve validating personal identity documents. In art, antiques and anthropology Authentication can be considered to be of three types: The ''first'' type of authentication is accep ...

Computer Hardware
Computer hardware includes the physical parts of a computer, such as the central processing unit (CPU), random-access memory (RAM), motherboard, computer data storage, graphics card, sound card, and computer case. It includes external devices such as a Computer monitor, monitor, Computer mouse, mouse, Computer keyboard, keyboard, and Computer speakers, speakers. By contrast, software is a set of written instructions that can be stored and run by hardware. Hardware derived its name from the fact it is ''Hardness, hard'' or rigid with respect to changes, whereas software is ''soft'' because it is easy to change. Hardware is typically directed by the software to execute any command or Instruction (computing), instruction. A combination of hardware and software forms a usable computing system, although Digital electronics, other systems exist with only hardware. History Early computing devices were more complicated than the ancient abacus date to the seventeenth century. French ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data
Data ( , ) are a collection of discrete or continuous values that convey information, describing the quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted formally. A datum is an individual value in a collection of data. Data are usually organized into structures such as tables that provide additional context and meaning, and may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data are commonly used in scientific research, economics, and virtually every other form of human organizational activity. Examples of data sets include price indices (such as the consumer price index), unemployment rates, literacy rates, and census data. In this context, data represent the raw facts and figures from which useful information can be extracted. Data are collected using technique ...

Bank
A bank is a financial institution that accepts Deposit account, deposits from the public and creates a demand deposit while simultaneously making loans. Lending activities can be directly performed by the bank or indirectly through capital markets. As banks play an important role in financial stability and the economy of a country, most jurisdictions exercise a high degree of Bank regulation, regulation over banks. Most countries have institutionalized a system known as fractional-reserve banking, under which banks hold liquid assets equal to only a portion of their current liabilities. In addition to other regulations intended to ensure accounting liquidity, liquidity, banks are generally subject to minimum capital requirements based on an international set of capital standards, the Basel Accords. Banking in its modern sense evolved in the fourteenth century in the prosperous cities of Renaissance Italy but, in many ways, functioned as a continuation of ideas and concepts o ...

Authority
Authority is commonly understood as the legitimate power of a person or group of other people. In a civil state, ''authority'' may be practiced by legislative, executive, and judicial branches of government,''The New Fontana Dictionary of Modern Thought'' Third Edition, Allan Bullock and Stephen Trombley, Eds. p. 115. each of which has authority and is an authority. The term "authority" has multiple nuances and distinctions within various academic fields ranging from sociology to political science. In the exercise of governance, the terms ''authority'' and ''power'' are inaccurate synonyms. The term ''authority'' identifies the political legitimacy, which grants and justifies rulers' right to exercise the power of government; and the term ''power'' identifies the ability to accomplish an authorized goal, either by compliance or by obedience; hence, ''authority'' is the ''power'' to make decisions and the legitimacy to make such legal decisions and order their execution. ...
