In this type of attack, an attacker acts as the "go-between" of the user and the legitimate system, soliciting the token output from the legitimate user and then supplying it to the authentication system themselves. Since the token value is mathematically correct, the authentication succeeds and the fraudster is granted access.
The RSA SecurID authentication mechanism consists of a "token"—either hardware (e.g. a key fob) or software (a soft token)—which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card's factory-encoded almost random key (known as the "seed").
Example of a software token showing one-time passwords. A software token (a.k.a. soft token) is a piece of a two-factor authentication security device that may be used to authorize the use of computer services. [1] Software tokens are stored on a general-purpose electronic device such as a desktop computer, laptop, PDA, or mobile phone and can ...
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.
An access token is used by Windows when a process or thread tries to interact with objects that have security descriptors (securable objects). [1] In Windows, an access token is represented by the system object of type Token. An access token is generated by the logon service when a user logs on to the system and the credentials provided by the ...
A software-based authenticator (sometimes called a software token) may be implemented on a general-purpose electronic device such as a laptop, a tablet computer, or a smartphone. For example, a software-based authenticator implemented as a mobile app on the claimant's smartphone is a type of phone-based authenticator. To prevent access to the ...
Security token service (STS) is a cross-platform open standard core component of the OASIS group's WS-Trust web services single sign-on infrastructure framework specification. cf. [1] [2] Within that claims-based identity framework, a secure token service is responsible for issuing, validating, renewing and cancelling security tokens. The ...
A software token (a.k.a. soft token) is a type of two-factor authentication security device that may be used to authorize the use of computer services. Software tokens are stored on a general-purpose electronic device such as a desktop computer, laptop, PDA, or mobile phone and can be duplicated.
