+# 2. Hardened Kernel Boot Parameters
+
+Below is a curated set of kernel boot parameters optimized for CISS Debian Installer. These parameters enhance security posture,
+restrict legacy interfaces, enforce memory initialization, and disable speculative side channels. Each parameter is documented 
+with a short rationale.
+
+* ``audit=1``: Enable kernel auditing subsystem.
+* ``audit_backlog_limit=8192``: Set audit event buffer depth.
+* ``cfi=kcfi``: Enable Clang's Control Flow Integrity (if supported by kernel).
+* ``debugfs=off``: Disable debugfs mount, prevents access to kernel internals.
+* ``efi=disable_early_pci_dma``: Prevent early PCI DMA via EFI.
+* ``hardened_usercopy=1``: Harden copy_*_user() functions, mitigate heap/memcpy bugs.
+* ``ia32_emulation=0``: Disable 32-bit x86 binary support on 64-bit kernel.
+* ``init_on_alloc=1``: Zero-initialize heap memory on allocation.
+* ``init_on_free=1``: Zero memory on free to prevent reuse data leaks.
+* ``iommu=force``: Enforce use of IOMMU.
+* ``iommu.strict=1``: Enable strict IOMMU mode (always remap).
+* ``iommu.passthrough=0``: Prevent IOMMU passthrough (forces remapping).
+* ``kfence.sample_interval=100``: Enable low-overhead heap-fence sampling.
+* ``kvm.nx_huge_pages=force``: Enforce NX-bit for KVM hugepages to prevent code execution.
+* ``l1d_flush=on``: Flush L1D cache on VM-entry to mitigate cache side-channels.
+* ``lockdown=confidentiality``: Enable kernel lockdown in confidentiality mode.
+* ``loglevel=0``: Silence all kernel messages (only EMERG shown).
+* ``mitigations=auto,nosmt``: Enable all available speculative mitigations, disable SMT.
+* ``mmio_stale_data=full,force,nosmt``: Mitigate MMIO stale data side channel fully.
+* ``nosmt=force``: Force disable Simultaneous Multithreading (SMT/HT).
+* ``oops=panic``: Trigger kernel panic on oops, ensures halt on fault.
+* ``page_alloc.shuffle=1``: Randomize page allocator freelist order.
+* ``page_poison=1``: Fill freed pages with poison patterns to detect UAF.
+* ``panic=-1``: Prevent automatic reboot after panic.
+* ``pti=on``: Enable Page Table Isolation (Meltdown mitigation).
+* ``random.trust_bootloader=off``: Do not trust RNG state from bootloader.
+* ``random.trust_cpu=off``: Do not trust CPU's RDRAND or RDSEED.
+* ``randomize_kstack_offset=on``: Enable randomized kernel stack offset per syscall.
+* ``randomize_va_space=2``: Enable full ASLR for mmap and heap.
+* ``retbleed=auto,nosmt``: Mitigate Retbleed exploit path via branch prediction.
+* ``rodata=on``: Enforce read-only sections for .rodata.
+* ``slab_nomerge``: Disable merging of similar slab caches.
+* ``vdso32=0``: Disable 32-bit vdso mapping (x86 compatibility).
+* ``vsyscall=none``: Disable vsyscall legacy mapping.
