A company requires staff to enter a username and a password before they can open the payroll application. Which type of IT control is this?
This is an access control. Requiring a username and password limits who can open the payroll application, preventing unauthorised use. It is not input validation, which checks data accuracy, nor a backup or output control, which deal with data recovery and distribution of reports.
- AAccess controlCorrect
- BInput validation control
- CBackup control
- DOutput distribution control
Explanation
Usernames and passwords restrict who can enter the system, so they are access controls. Input validation checks the data entered, not the identity of the user. Backup controls protect against data loss, and output controls manage reports produced.
