Prerequisites for implementing STIG

You must prepare your IBM QRadar setup before you implement STIG.

Hardware

All QRadar hardware that is required in the deployment must be available and ready to configure.

Software

The hardening script is included in the QRadar ISO image. You can install RHEL 7 separately, but you don't have to because QRadar 7.5.0 comes with the pre-requisite RPMs installed, suitable partitioning, and uses LVM.

The only time you might need to pre-install RHEL is when you use custom hardware, or if you use software features that are not supported by QRadar, such as full disk encryption.
