Full-time analysts may want to create a dedicated Analyst VM. This is a full GNOME desktop environment including Chromium web browser, NetworkMiner, Wireshark, and other analyst tools. This allows you to investigate pcaps and other potentially malicious artifacts without impacting your Security Onion deployment or your workstation.
The Analyst desktop currently only supports CentOS, so you’ll either need to use our Security Onion ISO image (recommended) or a manual installation of CentOS 7.
There are a few different ways to install the Analyst desktop:
Our Security Onion ISO image includes a boot menu option for Analyst installs that will partition your disk appropriately and immediately perform an Analyst installation.
If you’re doing a network installation on CentOS 7 (NOT using our Security Onion ISO image), then in our normal Setup wizard you can choose
OTHERand then choose
You can manually run
sudo so-analyst-install. This script is totally independent of the standard setup process, so you can run it before or after setup or not run setup at all if all you really want is the Analyst VM itself.
Joining to Grid
You can optionally join your Analyst installation to your grid. This allows it to pull updates from the grid and automatically trust the grid’s HTTPS certificate. It also updates the manager’s firewall to allow the Analyst installation to connect. Please note that Analyst installations won’t actually display on the Grid page.
If you choose not to join your Analyst installation to your grid, then you may need to run so-allow on the manager node and choose the
analyst option to allow the traffic through the host-based Firewall.
