General system requirements

requires certain minimum system requirements. Your environment must meet or exceed these requirements. This section details operating systems, web browsers, system storage, Linux file systems, and other requirements for operating .

Supported operating systems

supports these operating systems and versions:

  • Red Hat Enterprise Linux 7.6 through 7.9
  • Red Hat Enterprise Linux 8.0 and any of the minor versions of 8.
    You can use the most recent minor release of RHEL 8 that is available at the time of the Splunk SOAR (On-premises) release.

  • Amazon Linux 2

Splunk SOAR (On-premises) cannot be installed inside of a Docker or Podman container.

Federal Information Processing Standard (FIPS) support

can be deployed in a FIPS compliant mode, if the operating system kernel is in FIPS mode.

  • Your operating system, either RHEL or CentOS must be in FIPS mode.
  • You must create a new, unprivileged deployment of , either as a single instance or as a cluster.

You can learn more about setting your operating system to use FIPS mode from the operating system vendor's websites:

Supported browsers

requires a web browser that supports HTML 5, SVG graphics, and TLS.

Use the latest, fully patched version of one of the following browsers:

  • Google Chrome
  • Mozilla Firefox
  • Microsoft Edge
  • Apple Safari

Operating system accounts

On unprivileged deployments, only a single operating system user account, phantom, is created and used.

Supported file systems and required directories

supports any file system where the user account running the application can be given write permissions.

In a clustered environment, implements GlusterFS for its file shares. If your organization requires a different file system for your cluster, make sure that the user account running has write permissions to the required directories.

Required directories for an installation as an unprivileged user:

  • <phantom_install_dir>/apps
  • <phantom_install_dir>/local_data/app_states
  • <phantom_install_dir>/scm
  • <phantom_install_dir>/vault
  • <phantom_install_dir>/tmp/shared

File permissions

is installed in the following environments:

  • On an unprivileged AMI deployment - /opt/phantom, also called <PHANTOM_HOME>.
  • On an unprivileged deployment - the home directory of the user account that will run , also called <PHANTOM_HOME>.

The installer expects a umask of 0022 during installation. Applying a different umask may lead to unexpected behavior.

In general, you should not modify file permissions for . Changing the file permissions can cause errors, or prevent from working.

You can check to see if an access control list has been applied using the Linux getfacl command, clear any access control list which is incorrectly being applied using the setfacl -b command, or apply correct permissions to a file with the chmod command. If you have changed file permissions, you will need to restart .
