The user-based access methods work by authorizing specific users to connect to the server. When a client establishes a connection to a server, it has to prove being controlled by an authorized user. The two methods based on authenticating users using networked identity management systems are SUN-DES-1 and MIT-KERBEROS-5.
Authentication and access control are often combined into a single operation, so that access is approved based on successful authentication, or based on an anonymous access token. Authentication methods and tokens include passwords, biometric analysis, physical keys, electronic keys and devices, hidden paths, social barriers, and monitoring by ...
Authentication, authorization, and accounting (AAA) is a framework used to control and track access within a computer network.. Authentication is concerned with proving identity, authorization with granting permissions, accounting with maintaining a continuous and robust audit trail via logging.
User-delegated tokens: These are tokens such as OAuth [2] which are granted based on user authentication. Policy & attribute-based access control: policies use attributes to define how APIs can be invoked using standards such as ALFA or XACML. The above methods provide different level of security and ease of integration.
Attribute-based access control (ABAC), also known as policy-based access control for IAM, defines an access control paradigm whereby a subject's authorization to perform a set of operations is determined by evaluating attributes associated with the subject, object, requested operations, and, in some cases, environment attributes.
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.
In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials> , where <credentials> is the Base64 encoding of ID ...
Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
