Step-by-Step Linux Kernel Optimization and Security Hardening Configurations

Default Linux kernel networking parameters are configured for generalized workloads and often throttle TCP buffer sizes and network queue depths. Applying enterprise sysctl tuning and modern TCP congestion algorithms significantly enhances request throughput while neutralizing common network attack vectors.

1. Implementing High-Performance Sysctl Security & Network Parameters

Create and edit /etc/sysctl.d/99-finland-security.conf to optimize network buffer sizing, prevent IP spoofing, and eliminate connection bottlenecks:

# /etc/sysctl.d/99-finland-security.conf
# File system descriptor capacity
fs.file-max = 2097152
fs.inotify.max_user_watches = 524288

# TCP Connection Backlog Queue Optimizations
net.core.somaxconn = 65535
net.core.netdev_max_backlog = 65536
net.ipv4.tcp_max_syn_backlog = 65536

# Network Security & SYN Flood Protection
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_synack_retries = 2
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.default.accept_redirects = 0
net.ipv4.conf.all.send_redirects = 0
net.ipv4.conf.default.send_redirects = 0
net.ipv4.conf.all.accept_source_route = 0
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.icmp_echo_ignore_broadcasts = 1

# TCP Buffer Allocations (Optimized for High-Throughput 1Gbps Links)
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216

# Socket Lifecycle and Fast TCP Recycling
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_fin_timeout = 15
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_keepalive_probes = 5
net.ipv4.tcp_keepalive_intvl = 15

# Enable Google BBR Congestion Control Algorithm
net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr

# Memory Management and Swappiness Suppression
vm.swappiness = 10
vm.dirty_ratio = 15
vm.dirty_background_ratio = 5
vm.vfs_cache_pressure = 50

Activate the configuration immediately using the system reload command:

sudo sysctl --system
# Verify that Google BBR is actively handling congestion control
sysctl net.ipv4.tcp_congestion_control

2. Configuring Security Limits and User File Handles

Web servers (Nginx, Apache) and relational databases (MySQL, PostgreSQL) require high file descriptor thresholds to service concurrent visitor requests without generating Too many open files socket errors. Configure /etc/security/limits.d/99-nofile.conf:

# /etc/security/limits.d/99-nofile.conf
*          soft    nofile     1048576
*          hard    nofile     1048576
root       soft    nofile     1048576
root       hard    nofile     1048576
www-data   soft    nofile     1048576
www-data   hard    nofile     1048576
nginx      soft    nofile     1048576
nginx      hard    nofile     1048576
mysql      soft    nofile     1048576
mysql      hard    nofile     1048576

3. Administrative SSH Hardening and Firewall Configuration

Harden administrative shell access to block automated brute-force attempts. Update /etc/ssh/sshd_config.d/security.conf:

# /etc/ssh/sshd_config.d/security.conf
Port 2255
PermitRootLogin prohibit-password
PasswordAuthentication no
PubkeyAuthentication yes
MaxAuthTries 3
ClientAliveInterval 300
ClientAliveCountMax 2
X11Forwarding no

Implement stateful firewall rules using ufw to permit traffic exclusively on production service ports:

# Default firewall policies
sudo ufw default deny incoming
sudo ufw default allow outgoing

# Open required production ports
sudo ufw allow 2255/tcp comment 'Hardened SSH Port'
sudo ufw allow 80/tcp comment 'HTTP Web'
sudo ufw allow 443/tcp comment 'HTTPS Web'

# Rate-limit SSH attempts
sudo ufw limit 2255/tcp

# Enable firewall
sudo ufw enable
