The Tanium Operating System (TanOS) must notify system administrators (SAs) and information system security officers (ISSOs) when accounts are created.

Description
Once an attacker establishes access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to 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 operating system user accounts and notifies administrators and ISSOs that it 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 operating systems can be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.

Check Text (C-254856r1015854_chk)

1. Access the TanOS interactively. 2. Press "A" for "Appliance Configuration Menu," and then press "Enter". 3. Press "4" for "Syslog Configuration," and press then "Enter". 4. Press "1" for "Check current status," and then press "Enter". If the syslog status page states, "No existing TanOS syslog forwarding configuration found", this is a finding. If the syslog status page states, "Syslog forwarding configuration" and the SIEM administrator verifies SIEM is receiving the events correctly and generating notifications for account creation events, this is not a finding.

Fix Text (F-58413r866108_fix)

1. Access the TanOS interactively. 2. Press "A" for "Appliance Configuration Menu," and then press "Enter". 3. Press "4" for "Syslog Configuration," and then press "Enter". 4. Press "5" for "Configure syslog forwarding," and then press "Enter". 5. Enter the destination host (IP address or hostname) provided by the SIEM administrator, and then press "Enter". 6. Enter the destination port number, and then press "Enter". 7. If TLS is required for this syslog destination, enter "Yes", otherwise enter "No", and then press "Enter". 8. Enter the destination protocol, "udp" or "tcp", and press "Enter". 9. Work with the SIEM administrator to validate events are being received, and to configure notifications for account creation events.
