Versa Security Packages (SPack) #
In this article, we will understand how to download and install a SPack on the Versa Director node, and how to configure SPack updates on Versa VOS branch Appliance.
A Security Pack (SPack) is a software bundle that contains predefined objects that you can use in firewall configurations to protect network devices from security threats. The predefined objects include applications, URL categories, URL reputations, IP reputations, IDS and IPS signature definitions, and antivirus definitions. The SPacks are stored in a database repository on the Director node.
When we first deploy headend and branch network components, a SPack is preinstalled on a Director node, based on the subscription type. Versa Networks updates SPacks frequently, and each update contains the latest signatures to protect against new threats.
It is recommended that the SPack is updated regularly and a recommended configuration is to pull this update automatically from Versa’s cloud servers. Updating the SPack has no operational impact on a running Director node or the VOS appliance.
The content of the SPack applicable to each node or branch appliance depends on the type of software license subscription that it is entitled to.
On the Director node, we have the flexibility to download the full SPack or have incremental updates alone.
We have three sections in this –
- Configuring SPack Downloads on the Versa Director
- Install SPack on Versa VOS appliance
- Configure Daily and Real-Time updates in the VOS appliance
Configuring SPack Downloads on the Versa Director #
Step 1: In Director view, select the Administration tab in the top menu bar
Step 2: Select Inventory > Security Packages in the left menu bar to view the SPacks that are downloaded and installed on Versa Director.
The main pane displays a list of downloaded SPacks.

Step 3: Click the 'Edit' option to edit the SPack configuration - Add the spack download URL - https://spack.versanetworks.com/versa-updates
In the SPack configuration field, configure the URL from where the Director will download the latest Security Packages. We can also define if we want Full or Incremental Download and the timeout value in case the Director is unable to reach the cloud server. This can be anywhere between 300 to 3600 Secs (5 to 60 Hours) with a Default value of 300.
Also, we can Schedule SPack downloads and define a timer interval after which the Director Node attempts to re-try the download after a failed attempt. The default value is 900 Secs.
When an SPack is downloaded successfully, the Status in the SPack information Tab changes to DOWNLOAD_COMPLETE.
