Cyber Security: Security Onion Install
If you want to install Security Onion using our ISO image:
Review the Hardware Requirements and Release Notes sections.
Download and verify our Security Onion ISO image. https://download.securityonion.net/file/securityonion/securityonion-2.3.260-20230620.iso
Boot the ISO in a machine that meets the minimum hardware specs.
Follow the prompts to complete the installation and reboot.
You may need to eject the ISO image or change the boot order of the machine to boot from the newly installed OS.

Security Onion Setup will automatically start. If for some reason you have to exit Setup and need to restart it, you can log out of your account and then log back in and it should automatically start. If that doesn’t work, you can manually run it as follows:
sudo SecurityOnion/setup/so-setup iso Proceed to the Configuration section.
