Business accounts allow you to read data, edit content, and perform tasks. If they are shared without criteria, it becomes difficult to reconstruct who did what and intervene when responsibilities change. Access management belongs to the organization of work.
I propose an inventory of essential services with referent, recovery methods and authorized persons. The availability of an application does not imply that everyone should have the same powers. Access should be linked to the task and reviewed when that task changes.
Multi-factor authentication adds verifications in addition to the password, as illustrated in CISA materials. It does not eliminate all risk and requires a proper recovery path. The choice of method must also consider service features and relevant threats.
A hypothetical example is a contributor who finishes their assignment by keeping access to a folder. The exit procedure should include revocation and transfer of the necessary information, without depending on the memory of a single person. Periodic control makes it possible to detect accesses that are no longer relevant. The aim is to make work possible for authorised persons and to keep responsibilities on digital services understandable.
