What type of system allows a user to authenticate once to access multiple services?
What are the 4 processes of an access control system?The core access control process involves four steps: identification, authentication, authorization, and accounting.
What are four means of authenticating a user's identity?Four-factor authentication (4FA) is the use of four types of identity-confirming credentials, typically categorized as knowledge, possession, inherence and location factors.
What type of cryptographic operation's are non reversible?Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext. This operation is reversible. Anyone who knows or obtains the secret key can decrypt the ciphertext and read the original input. Hashing functions are not reversible.
Which of the following is an authentication system that issues a ticket after verifying the credentials by which you can authenticate other services?Kerberos uses a ticket-granting ticket server for authentication. Users claim an identity with a username for identification. They prove their identity with credentials for authentication and Kerberos incorporates these credentials in tickets.
