While the RSA SecurID system adds a layer of security to a network, difficulty can occur if the authentication server's clock becomes out of sync with the clock built into the authentication tokens. Normal token clock drift is accounted for automatically by the server by adjusting a stored "drift" value over time.
A security token is a peripheral device used to gain ... via an untrusted network ... user and then supplying it to the authentication system themselves. ...
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.
The Generic Security Service Application Program Interface (GSSAPI, also GSS-API) is an application programming interface for programs to access security services. The GSSAPI is an IETF standard that addresses the problem of many similar but incompatible security services in use as of 2005 [update] .
Logical security consists of software [1] safeguards for an organization's systems, including user identification and password access, authenticating, access rights and authority levels. These measures are to ensure that only authorized users are able to perform actions or access information in a network or a workstation.
Tokens generically are something the claimant possesses and controls that may be used to authenticate the claimant's identity. In e-authentication, the claimant authenticates to a system or application over a network. Therefore, a token used for e-authentication is a secret and the token must be protected.
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 ...
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 ...
