Description
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of re-establishing access. One way to accomplish this is for the attacker to simply create a new account. Notification of account creation is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail, which documents the creation of application user accounts and notifies administrators and Information System Security Officers (ISSO) exists. Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes. To address access requirements, many application developers choose to integrate their applications with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements. Such integration allows the application developer to offload those access control functions and focus on core application features and functionality.

1. Using a web browser on a system that has connectivity to the Tanium Application, access the Tanium Application web user interface (UI) and log on with multi-factor authentication. 2. Click "Modules" on the top navigation banner. 3. Click "Connect". 4. Review the configured connections. If no sources exist to send audit logs from Tanium to a SIEM tool or email destination, this is a finding. Work with the SIEM administrator to determine if an alert is configured when accounts are created. If there is no alert configured, this is a finding.
