TrueNAS system management options are collected in this section of the UI and organized into a few different screens:

Update controls when the system applies a new version. There are options to download and install an update, have the system check daily and stage updates, or apply a manual update file to the system.
General Settings shows system details and has basic, less intrusive management options, including web interface access, and localization of the UI and keyboard. This is also where users can download a system debug, input an Enterprise license, or create a software bug ticket.
Advanced Settings contains options that are more central to the system configuration or meant for advanced users. Specific options include configuring the system console, log, and dataset pool, managing sessions, adding custom system controls, kernel-level settings, scheduled scripting or commands, global two-factor authentication, NTP server connections, and determining any isolated GPU devices.
TrueNAS Enterprise
Enterprise-licensed system administrators have additional options to configure security-related settings, such as FIPS and STIG compatibility and Self-Encrypting Drive (SED) configuration. Enterprise-licensed HA systems have access to the failover settings located on this screen.
Advanced settings have reasonable defaults in place. A warning message displays for some settings advising of the dangers of making changes. Changing advanced settings can be dangerous when done incorrectly. Use caution before saving changes.
Make sure you are comfortable with ZFS, Linux, and system configuration, backup, and restoration before making any changes.
Boot lists each ZFS boot environment stored on the system. These restore the system to a previous version or a specific point in time.
Services displays each system component that runs continuously in the background. These typically control data sharing or other external access to the system. Individual services have their own configuration screens, start and stop buttons, and can be set to start automatically.
Shell allows users to use the Linux command-line interface (CLI) directly in the web UI.
Alert Settings allows users to configure Alert Services and to adjust the threshold and frequency of various alert types. See Alerts Settings Screens for more information.
Audit allows users to review auditing logs of all actions performed by a session, user, or service (SMB, middleware).
Enclosure appears when the system is attached to compatible TrueNAS hardware. This is a visual representation of the system with additional details about disks and other physical hardware components.
