Managing System Software
========================

.. warning:: Updates are only available for licensed Policy Servers with an active Maintenance subscription.

Checking System Software Versions
---------------------------------

Software packages are identified by four parts. Name, Revision Number, Version
Number, and Revision Date.

- **NAC-CT** – Policy Server Software
- **NAC-SS** – Sensor Software
- **NAC-AGENT** – Agent Software

In addition to the software installed on the Policy Server or the Network
Sensor, the Policy Server may also store a software image to be used for
updating at a later time. For example, a Policy Server with version 5.0.19
installed may have a copy of Version 5.0.20 that can be used for updating the
Policy Server, Network Sensors, or Agents at a later time.

**System > Update > Genian Software** will display the newest version of
software stored on your Policy Server, even if it is not installed.

You can see the software version installed on individual Policy Servers and
Sensors by navigating to **System** in the top panel. All appliances will be
shown in the view pane along with the installed software.
