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.
Tokens can contain chips with functions varying from very simple to very complex, including multiple authentication methods. The simplest security tokens do not need any connection to a computer. The tokens have a physical display; the authenticating user simply enters the displayed number to log in.
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.
In computer systems, an access token contains the security credentials for a login session and identifies the user, the user's groups, the user's privileges, and, in some cases, a particular application. In some instances, one may be asked to enter an access token (e.g. 40 random characters) rather than the usual password (it therefore should ...
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 be duplicated.
A network security policy (NSP) is a generic document that outlines rules for computer network access, determines how policies are enforced and lays out some of the basic architecture of the company security/ network security environment. [1] The document itself is usually several pages long and written by a committee.
Network security are security controls, policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1] Network security involves the authorization of access to data in a network, which is controlled by the network ...
A sample of token. 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.
