Which type of group can be used for controlling access to objects?

Which type of group can be used for controlling access to objects? Which type of group can be used for controlling access to objects? Only security groups can be used for controlling access to objects. A discretionary access control list (DACL) is an implementation of discretionary access control (DAC).

Which of the following commands creates a new group? To create a new group, use the groupadd command.

Which type of group can be used for controlling access to objects? – Additional Questions

How do you handle data confidentiality?

When managing data confidentiality, follow these guidelines:
  1. Encrypt sensitive files.
  2. Manage data access.
  3. Physically secure devices and paper documents.
  4. Securely dispose of data, devices, and paper records.
  5. Manage data acquisition.
  6. Manage data utilization.
  7. Manage devices.

What can be used to ensure confidentiality of sensitive data?

To ensure data confidentiality, the most straightforward method is to encrypt all the sensitive data for storage, processing, and transmission. While data encryption provides a satisfying level of security protection, there are several subtle and challenging issues to be addressed, which we can list as follows: –

How do you achieve confidentiality in cryptography?

When the goal is to achieve confidentiality, a recipient’s public key is used to encrypt messages. On receiving the message, the recipient is able to decrypt the message using his or her pri-vate key. In an asymmetric key cryptosystem, a public key cannot be used to derive the private key.

How is data confidentiality achieved by encryption algorithms?

Once the sender has the public key of their recipient, they can use it to encrypt the data that they want to keep secure. Once it has been encrypted with a public key, it can only be decrypted by the private key from the same key pair.

What four basic protections can cryptography support?

Cryptography can support confidentiality, integrity, authentication, and non-repudiation.

How do you get authentication in cryptography?

The user is authenticated by sending to the authentication server his/her username together with a randomly challenge message that is encrypted by the secret key. Whereby, the user is considered as authenticated user if the server can match the received encrypted message using its share secret key.

What are the 3 methods of authentication?

Authentication factors can be classified into three groups: something you know: a password or personal identification number (PIN); something you have: a token, such as bank card; something you are: biometrics, such as fingerprints and voice recognition.

What is the most secure authentication method?

Experts believe that U2F/WebAuthn Security Keys are the most secure method of authentication. Security keys that support biometrics combine the Possession Factor (what you have) with the Inherence Factor (who you are) to create a very secure method of verifying user identities.

What are the three strategies that can be used to authenticate a user to a computer system?

Operating Systems generally identify/authenticates users using the following 3 ways: Passwords, Physical identification, and Biometrics.

What protocol should be used when simple username password authentication is needed?

Password Authentication Protocol (PAP) is a simple user authentication protocol that does not encrypt the data and sends the password and username to the authentication server as plain text.

Which technology can be implemented as part of an authentication system to verify the identification of employees?

The answer is smart card readers. Smart card readers can be implemented as part of an authentication system to verify the identification of employees.

Which of the authentication method according to you is most secure and efficient support your answer with appropriate reason and example?

Nowadays, the usage of biometric devices such as hand scanners and retinal scanners is becoming more common in the business environment. It is the most secure method of authentication.

Which of the following is the most securing of authentication for user to access any system?

Password-based authentication

The most common authentication method, anyone who has logged in to a computer knows how to use a password.

Which of the following is most common authentication process used nowadays for advanced security functions in both public and private domains?

Password-based authentication

Passwords are the most common methods of authentication. Passwords can be in the form of a string of letters, numbers, or special characters.

What authentication protocol would you recommend for accessing services securely over a physically insecure network?

Kerberos is a network authentication protocol that allows users to securely access services over a physically insecure network. Kerberos, or MIT Kerberos, is also the name of this application.

Which protocol is used to transmit the username and password over a network and compared to a table of name password pairs?

Kerberos, a network authentication protocol included in the Microsoft Windows operating systems, can now be used in conjunction with Security Support Provider Interface (SSPI) to provide pass-through authentication with secret key cryptography and data integrity.

Which authentication method is commonly used for more secure wireless networks?

WPA2-Enterprise requires the use of a secure EAP method to authenticate. The most commonly used include PEAP-MSCHAPv2, EAP-TTLS/PAP, and EAP-TLS. It can be configured to accept a wide variety of identifiers and can enable MFA for a more secure authentication experience.
