Description
Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. If temporary accounts remain active when no longer needed, they may be used to gain unauthorized access. The risk is greater for the network device since these accounts have elevated privileges. To mitigate this risk, automated termination of all temporary accounts must be set upon account creation.
