Description
When emergency accounts are created, there is a risk that the emergency account may remain in place and active after the need for the account no longer exists. To address this, in the event emergency accounts are required, accounts that are designated as temporary in nature must be automatically terminated after an organization-defined time period. Such a process and capability greatly reduces the risk that accounts will be misused, hijacked, or data compromised.
