Abstract: Various aspects of the disclosure relate to identifying and disabling dormant service accounts. An account management system automatically analyzes service account activity records to determine whether each service account defined for an enterprise network is in use. Automated monitoring applications may be used for identifying and authenticating events and/or authentications of service accounts across an enterprise network. When particular service accounts are identified as being potentially dormant, based on an identified date of last use meeting a threshold condition, the associated service accounts are flagged as being dormant. Setting an account as being dormant triggers solicitation of feedback confirming the dormant setting, which causes disablement of the service account. The account management system triggers decommissioning of the dormant service accounts upon expiration of a disablement threshold.
