ModSecurity is not limited to Apache — it can also protect Nginx deployments through a dedicated dynamic module called ngx_http_modsecurity_module. The module embeds the ModSecurity v3 library directly into Nginx’s request processing pipeline, enabling the same OWASP Core Rule Set that Apache users rely on. On RHEL 8, Nginx is available from the AppStream module […]
Introduction How to Install BIND9 DNS Server on Debian 13 is a fundamental operation for any administrator maintaining a Debian 13 Trixie server. Debian 13 Trixie ships with the Linux 6.12 kernel, updated toolchains, and a fully refreshed package archive — meaning version numbers, configuration file paths, and some dependency chains differ from Debian 12.

ModSecurity is a widely-deployed open-source Web Application Firewall (WAF) that integrates directly with Apache as a module. Combined with the OWASP Core Rule Set (CRS), it provides protection against the most common web attack categories including SQL injection, cross-site scripting, and remote code execution. On RHEL 8, both the mod_security Apache module and the mod_security_crs […]
Introduction Deploying configure squid proxy on a Debian 13 Trixie machine is straightforward thanks to Debian’s policy-compliant packaging.

This tutorial stays on the systemd path throughout. Prerequisites Ensure Debian 13 Trixie is fully […]
Caddy is a modern, open-source web server written in Go that automatically provisions and renews TLS certificates via Let’s Encrypt. Unlike Apache or Nginx, Caddy requires almost no manual TLS configuration, making it an excellent choice for developers who want HTTPS out of the box. On RHEL 8, Caddy is not available in the default […]

Load balancing distributes incoming client requests across multiple backend servers, preventing any single server from becoming a bottleneck and improving both throughput and fault tolerance. Nginx’s built-in load balancing is highly capable and available in the open-source version without any additional modules for most common use cases. On RHEL 8, you can configure Nginx to […]
Introduction This guide explains how to Set Up WireGuard VPN on Debian 13 on Debian 13 Trixie. Debian Trixie uses systemd for service management, nftables as the underlying packet filter (with ufw or iptables front-ends still available), and AppArmor for mandatory access control.

HTTP/2 delivers significant performance improvements over HTTP/1.1 through features such as header compression, request multiplexing, and server push — all over a single TCP connection. Nginx has supported HTTP/2 since version 1.9.5, and on RHEL 8 the AppStream version of Nginx is compiled with the necessary OpenSSL support to enable it. Because browsers only implement […]
