Computer Security Authentication

Computer security authentication is the process of verifying the identity and login credentials of users to a network. To prove identity to the network, passwords, digital certificates and smart cards can all be used. Computer security authentication can be used to verify message integrity, e mail authentication and MAC (Message Authentication Cod), as well as checking the integrity of a message transmitted. There are several options for human authentication. These include challenge-response, password, digital signature and biometrics.

Human authentication means that the transaction was initiated by a person and not by a computer. The authentication method of challenge-response authentication proves the identity of the user who logs onto the network. The network access server, wireless access point, or authentication server creates an authentication challenge when a user logs in. This challenge is typically a random number that is sent to the client's machine. Client software uses its password for encryption and sends the result back via a one-way have function or encryption algorithm. This is the answer.

Two-factor authentication requires two separate ways to establish identity. Strong authentication refers to the use of more than one factor for authentication. This cisco panama is in contrast to traditional password authentication which only requires one factor to gain access. Password is a secret code or word that serves as a security measure to prevent unauthorized access to data. It is usually managed by the operating system, or DBMS. A computer can verify the legality and legality of the password but not the legality or legality of the user.

Two of the most important uses of digital signatures include setting up secure connections to websites and verifying files are authentic. IP spoofing is the act of inserting an authorized user's IP address into the transmissions of an unauthorized user to gain illegal access.

Biometrics provides a safer method of authentication than typing passwords, or using smart cards that could be stolen. Some methods have high failure rates. One example is fingerprint capture from a water glass. Another example is fool scanners.
