Prerequisites

Make sure that your system meets the system and network requirements.

Check the following prerequisites for your environment before installing the Edge Gateway software. The prerequisites apply to both the standalone and virtual appliance formats of the Edge Gateway software (run file or ova respectively) except as noted:
  • If the Orchestration & Automation application is behind a firewall, such as in a cloud configuration, configure the firewall to allow the Edge Gateway access port number 443. This port number is required for the app to connect to Orchestration & Automation data using the REST API and STOMP messaging protocol. The connections are “inbound-only” from the Edge Gateway to the Orchestration & Automation application.
  • IBM recommends that you install the Edge Gateway on a system other than the one hosting the IBM Security QRadar Suite. The prerequisites for the system hosting the Edge Gateway are as follows:
    • Operating system: Red Hat Enterprise Linux v7.4 to v7.9 and 8.4 to 8.6.
    • Minimum 5 GB free disk space.
    • Minimum 2 GB RAM.
    • Minimum two CPUs.
    • Dedicated operating system account for running apps.
    • If you are installing the standalone format, a user account on the system with sudo privileges is required.
    • Access to the Orchestration & Automation application.
    • Access to any third-party applications required by the Orchestration & Automation apps that you install.
    • If you are installing the Edge Gateway virtual appliance, also make sure TCP port number 22 is accessible.
  • The rest and stomp routes hosts must be added to a DNS server.
  • Make sure the Edge Gateway is not on a network using IP addresses 10.42.x.x or 10.43.x.x. Kubernetes require those IP ranges for its cluster and service respectively. Contact IBM Security Support for assistance if you require that the Edge Gateway be on such a network.
  • If you are installing the standalone format, make sure that the partitions that host the following directories have the minimum required free disk space. IBM Security recommends using the Logical Volume Manager (LVM) to manage your partitions:
    • 400 MB for /boot
    • 20 GB for /
    • 70 GB for /var/lib
    • 10 GB for /var/log
  • If you are installing the standalone format using the .run file, the following packages must be installed. See Standalone software for the commands to install them.
    • createrepo package
    • container-selinux package

The minimum supported TLS version for the Kubernetes API server is TLS V1.2.

The resources required by the Edge Gateway server depend on the requirements of the apps installed. Some apps that operate on files in memory might have additional memory requirements. Apps that perform considerable computations, such as decryption tasks, might need more CPU. Therefore, you might need to increase those resources.
