Meaning – In the world of computer security, authorisation means the process of granting access to a certain file or entity, to an interested party. Organisations often exercise a structured approach to authorisation, and this ensures that the managers can oversee the activities of the employees under them, but not the other way round. This helps in maintaining a level of authority in the organisation.

On a more personal level, if you have a PC that has multiple user accounts, then you can restrict access to files on your account, by revoking authorisation of the other users on the PC. In a time where data security is of paramount importance, the process of authorisation is a step forward in ensuring the protection of the data or the files you seek to secure.

Example of usage“She did not grant authorisation to any of the files on her account as all her friends used the same PC.”
