Updating ATA to version 1.5
If ATA is not installed in your environment, download the full version of ATA, which includes version 1.5 and follow the standard installation procedure described in Install ATA.
If you already have ATA version 1.4 deployed, this procedure walks you through the steps necessary to update your installation.
Follow these steps to update to ATA version 1.5:
Download ATA v1.5 from VLSC or MSDN.
You can also use the updated full version of ATA to perform the update to version 1.5.
Update the ATA Center
Download the updated ATA Gateway package
Update the ATA Gateways
Update all the ATA Gateways to make sure ATA functions properly.
Step 1: Update the ATA Center
Back up your database: (optional)
If the ATA Center is running as a virtual machine and you want to take a checkpoint, shut down the virtual machine first.
If the ATA Center is running on a physical server, follow the recommended procedure to back up MongoDB.
Run the update file, Microsoft ATA Center Update.exe, and follow the instructions on the screen to install the update.
In the Welcome page, select your language and click Next.
Read the End-User License Agreement and if you accept the terms, click the checkbox, and click Next.
Select whether you want to run the full (default) or partial migration.
If you select Partial migration, any network traffic collected and forwarded Windows events analyzed by ATA are deleted and user behavioral profiles have to be relearned; this takes a minimum of three weeks. If you are running low on disk space, then it is helpful to run a Partial migration.
If you run a Full migration, you need additional disk space, as calculated for you on the upgrade page, and the migration may take longer, depending on the network traffic. The full migration retains all previously collected data and user behavioral profiles are maintained, meaning that it will not take additional time for ATA to learn behavior profiles and anomalous behavior can be detected immediately after update.
Click Update. Once you click Update, ATA is offline until the update procedure is complete.
After updating the ATA Center, the ATA Gateways will report that they are now outdated.
- Update all the ATA Gateways to make sure ATA functions properly.
Step 2. Download the ATA Gateway setup package
After configuring the domain connectivity settings, you can download the ATA Gateway setup package.
To download the ATA Gateway package:
Delete any previous versions of the ATA Gateway package you previously downloaded.
On the ATA Gateway machine, open a browser and enter the IP address you configured in the ATA Center for the ATA Console. When the ATA Console opens, click on the settings icon and select Configuration.
In the ATA Gateways tab, click Download ATA Gateway Setup.
Save the package locally.
The zip file includes the following files:
ATA Gateway installer
Configuration setting file with the required information to connect to the ATA Center
Step 3: Update the ATA Gateways
On each ATA Gateway, extract the files from the ATA Gateway package and run the file Microsoft ATA Gateway Setup.
You can also use this ATA Gateway package to install new ATA Gateways.
Your previous settings are preserved, but it may take a few minutes until for the service to restart.
Repeat this step for all other ATA Gateways deployed.
After successfully updating an ATA Gateway, the outdated notification for the specific ATA Gateway will go away.
You will know that all the ATA Gateways have been successfully updated when all the ATA Gateways report that they are successfully synced and the message that an updated ATA Gateway package is available is no longer displayed.
