Identify information system users, processes acting on behalf of users, or devices.
Authentication helps you to know who is using or viewing your system. Make sure to assign individual, unique identifiers, like user names, to all employees/users who access company systems. Confirm the identities of users, processes, or devices before allowing them access to the company's information system-usually done through passwords.
You lead a project with the Department of Defense (DoD) for your small company and want to make sure that all employees working on the project can log on to the company system to see important information about the project. You also want to prevent employees who are not working on the DoD project from being able to access the information. You set up the system so that when an employee logs on, the system uniquely identifies each person, then determines the appropriate level of access.
