Think Linux Mint is private out of the box? In this 2026 guide, we’re hardening Linux Mint Debian Edition (LMDE) from the ground up for maximum privacy and performance.
From kernel tweaks to app sandboxing, I'm showing you the "Zero-Trust" setup that turns your PC into a digital fortress.
Kernel Hardening:
Command - sudo nano /etc/sysctl.d/99-hardened.conf
Insert:
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.accept_redirects = 0
net.ipv6.conf.all.accept_redirects = 0
kernel.dmesg_restrict = 1
Stability:
Command - sudo nano /etc/sysctl.conf
Insert:
vm.swappiness=10
