Authentication and access control are critical components of computer system security. Authentication refers to the process of verifying the identity of a user or device, while access control refers to the process of limiting user access to resources based on their identity and level of authorization. In this section, we will explore some of the key concepts related to authentication and access control in computer system security.

  1. Password-Based Authentication: Password-based authentication is the most common method of authentication used in computer systems. Users are required to

enter a unique username and password combination to gain access to a system or resource. However, passwords are vulnerable to a variety of attacks, such as brute force attacks and password cracking attacks, so it is important to use strong passwords and change them regularly.

  1. Biometric Authentication: Biometric authentication is a newer method of authentication that uses unique physical characteristics, such as fingerprints, facial recognition, or iris scans, to verify a user's identity. Biometric authentication

compromise two different authentication factors in order to gain access.

  1. Access Control: Access control is the process of limiting user access to resources based on their identity and level of authorization. This can be done through various methods, such as assigning user roles or permissions, implementing network segmentation, or using firewalls and other security measures. Access control is essential for protecting sensitive data and preventing unauthorized access to resources.
  1. Authorization: Authorization is the process of granting or denying access to specific resources based on a user's identity and level of permission. This is typically done through the use of access control lists (ACLs) or role-based access control (RBAC) systems. Authorization is critical for ensuring that users only have access to the resources that they need to perform their job functions.
  2. Privileged Access Management: Privileged access management (PAM) is a process of managing and controlling access to privileged accounts,
