- q13- When attempting to access a resource, a user must supply a mutually agreed factor to the access control system. What is this phase of the process referred to? a. Authentication b. Impersonation c. Identification d. Authorisation e. AccountingA hypothetical scenario where the management of login credentials is necessary could be a large corporation that has multiple departments and employees with varying levels of access to sensitive information. In order to maintain security and prevent unauthorised access, the company would need to implement a system for managing login credentials. This would involve assigning unique usernames and passwords to each employee, as well as establishing protocols for resetting passwords and revoking access when necessary. Additionally, the company may choose to implement two-factor authentication or other security measures to further protect sensitive data. Identify and analyse the different authentication techniques that are currently accessible. Is the utilisation of a password mandatory in all instances?Consider the following scenario: you manage a website that provides hundreds of thousands of users with files. You can't handle all of the questions at once; you can only manage a few thousand. A sensible approach would be to serve 1000 persons in order of their arrival. This means you'll have to keep track of all incoming requests. Determine the most suitable ADT.
