AlmaLinux: From Firmware Preparation to Continuous Auditing

Setting Up an AlmaLinux System: From Hardware Planning to Enterprise Hardening Setting up an AlmaLinux system follows a structured process that spans from hardware planning to post-installation hardening, including resilience, reproducibility, and continuous auditing strategies. This guide integrates enterprise security best practices aligned with CIS, DISA STIG, and HIPAA benchmarks. 1. Preparation and Firmware (BIOS/UEFI) 1.1 System Requirements Minimum RAM: 1.5 GB (4 GB or more recommended for production) Disk space: 10 GB minimum, 20 GB recommended for general use Supported architectures: x86_64 (Intel/AMD), aarch64 (ARM64), ppc64le (PowerPC), s390x (IBM Z) 1.2 BIOS/UEFI Configuration It's essential to decide between legacy BIOS or UEFI before starting. UEFI is required to enable Secure Boot, a feature AlmaLinux supports to ensure only signed and authorized kernel modules are loaded. Verify boot order and disable Secure Boot if there are driver conflicts. The BIOS/UEFI choice deter
