A dormant account is a login account which has not had any login activity for an extended period of time, defined by being at least some N number of days.

Dormant accounts are generally assumed to be unneeded -- no use implies no need. Dormant accounts represent a security risk since any unusual use of the account will not be detected by the account's (inactive) owner.

Dormant accounts are related to, but not the same as, dormant users -- users all of whose accounts are dormant -- and to orphan accounts -- which are not associated with a valid identity.

A dormant account is one with no recent login activity. A dormant user profile is one that contains (at most) only dormant accounts. An orphan account is one not attached to a user profile (owner). An orphan user profile is one not linked to the organization, through a supervisor/manager.

Hitachi ID Identity Manager can be used to find orphan and dormant accounts and orphan and dormant user profiles:

  • ID mapping processes (automated, attribute-based or self-service) link accounts to user profiles.

  • Org-chart import (from HR, AD, etc.) and update workflows link users to their managers.

  • The last login time and date can be extracted from each managed system, for each account. Accounts that have not logged in recently can be flagged as dormant.

Reports are provided in Hitachi ID Identity Manager to identify orphan and dormant accounts and user profiles as per the above definitions. Report output can be fed directly into remediation requests (e.g., to disable dormant accounts) or into audit requests (e.g., to request further investigation).
