Network managers define access control by requiring authentication of the user's identity before permitting or limiting entry to a computer network or server
all RDBMS provide some mechanism for internal access control; each connecting process has a "user id" and not all user id's are able to see all tables or all fields of a given table Privileges are similar to file protection bits in a file system but more elaborate: read, write, update, delete are the basic set, and there are many more in some RDBMS
The process of preventing unauthorized access to the resources of an IT product, programs, processes, systems, or other IT products Some suppliers consider preventing unauthorized users from logging on to the system to be access control In reality, access control should also stop logged on users accessing objects (files, devices, etc) for which they have no authorization
The methods by which interactions with resources are limited to collections of users or programs for the purpose of enforcing integrity, confidentiality, or availability constraints
1) Limiting access to information system resources to authorized users, programs, processes, or other systems only 2) Procedures and controls that limit or detect access to MEI Resource Elements (People, Technology, Applications, Data and/or Facilities) thereby protecting these resources against loss of Integrity, Confidentiality Accountability and/or Availability
the process of limiting access to the resources of a system only to authorized programs, processes, or other systems (in a network) Synonymous with controlled access and limited access Access control may be an administrative, physical, or technical control, but is most commonly considered a technical control limiting access to information or resources on a system Access control is generally a preventive control
(1) Restrictions controlling a subject's access to an object [ANDE72, NCSC87] (2) The ability and the means necessary to store or retrieve data to communicate with or to make use of any resource of an ADP system [NCSC87] (3) Protection of system resources against unauthorized access; a process by which use of system resources is regulated according to a security policy and is permitted by only authorized entities (users, programs, processes, or other systems) according to that policy [IETF99]
The mechanisms for limiting access to resources based on users' identities and their membership in various predefined groups Access control is used typically to control user access to network resources such as servers, directories, and files
The restriction of access to network realms In an Apache context usually the restriction of access to certain URLs See: Authentication, Authorization, and Access Control
Protection of resources against unauthorized access; a process by which use of resources is regulated according to a security policy and is permitted by only authorized system entities according to that policy
The management of permissions and restrictions for logging onto a computer or network Systems typically employ individual profiles that specify which network-attached resources are available to which users The profiles are maintained in a database, such as RADIUS
In IWR, a property that grants a user class access to a report, URL, or report folder, and defines a scope See also, scope In PowerPlay Web, the mechanisms that limit user access to information or controls based on users identity and membership in predefined groups Access control is typically used by system administrators to control user access to network resources, such as servers, directories, and files In Upfront, the mechanisms for limiting access to certain items of information or to certain controls based on users' identity and their membership in various predefined groups Access control is typically used by system administrators to control user access to network resources such as servers, directories, and files See also, access privileges IWR, PowerPlay Web, Upfront
A method of restricting access to resources, allowing only privileged entities access (PGP, Inc ) Types of access control include, among others, mandatory access control, discretionary access control, time-of-day, classification, and subject-object separation
The collection of all controls used to assure that persons will have access only to information or information processing facilities for which they are authorized [X949] The collection of all controls used to assure that persons would have access only to information processing facilities for which they are authorized [x949] (includes credential, data separation)
Indicates the degree access to an adjoining roadway is controlled by public authority If there is, No access control (unlimited access); Full access control (ramp entry & exit only); or Other (partial access control) NOTE: Access is controlled by roadway configuration, not traffic control devices such as, No Left Turn signs, etc
The prevention of unauthorized entry into a specific area by using road barriers and traffic control The access-controlled area may be established to control and monitor a restricted area that may have undergone agent contamination
