🛡️ SecurityOPS - The Based Operating System

This configuration defines a secure, high-performance, and minimalist GNU Guix system for the host "securityops".

Tailored for advanced users, privacy-conscious professionals, security researchers, and intelligence agents who demand full control over kernel hardening, system optimizations, and GPU tuning.

🔧 Kernel Arguments & Flags

SecurityOPS kernel configuration includes the following arguments and flags:

quiet, splash – Minimal boot messages and graphical splash screen.
noatime – Improves disk performance by disabling file access timestamps.
zswap.enabled=1, zswap.compressor=zstd, zswap.max_pool_percent=15, zswap.zpool=z3fold – Enable compressed memory swap for performance and lower I/O.
elevator=bfq – BFQ I/O scheduler for fair disk access.
module.sig_enforce=1, lockdown=confidentiality, kptr_restrict=2 – Kernel hardening for module signing, lockdown mode, and pointer restrictions.
transparent_hugepage=always – Enable hugepages for memory efficiency.
mitigations=auto, spec_store_bypass_disable=prctl – CPU vulnerability mitigations (Spectre, Meltdown, etc.).
usbcore.authorized_default=0 – USB device security (anti-badusb).
tcp_congestion_control=bbr, net.core.default_qdisc=fq_codel – Networking optimizations for low-latency and high-throughput TCP traffic.
amdgpu.ppfeaturemask=0xffffffff, amdgpu.dc=0, amdgpu.dpm=0 – AMD GPU tuning and runtime power management.
irqaffinity=1-3, cpufreq.default_governor=schedutil, amd_pstate=active – CPU power/performance management.
amd_iommu=on, iommu=pt – IOMMU enabled for virtualization and security.
sysrq_always_enabled=1, watchdog – System behavior and emergency features.

🔐 Hardened Configuration Highlights

The SecurityOPS kernel integrates XanMod optimizations, Clear Linux performance patches, and KSPP self-protection. Key features include:

Stack protection with canaries (CONFIG_STACKPROTECTOR_STRONG).
Memory safety via CONFIG_INIT_ON_ALLOC_DEFAULT_ON, CONFIG_PAGE_POISONING, CONFIG_SLAB_FREELIST_HARDENED.
Randomization with CONFIG_KASLR and CONFIG_RANDOMIZE_KSTACK_OFFSET.
Module security through enforced cryptographic signing.
BPF hardening (CONFIG_BPF_JIT_ALWAYS_ON, CONFIG_BPF_JIT_HARDEN).
IOMMU protection for DMA isolation on AMD hardware.
