SELinux (Security-Enhanced Linux) enforces Mandatory Access Control (MAC) on RHEL 9, confining processes to only the resources they are explicitly permitted to access regardless of traditional Unix file permissions. While RHEL ships with comprehensive base policies, custom applications often generate AVC (Access Vector Cache) denials because their access patterns are not covered by existing policy […]
Introduction Setting up install timescaledb on a RHEL 10 server is a common task for system administrators, DevOps engineers, and site reliability engineers. This guide explains how to Install TimescaleDB on RHEL 10, with all the commands you need, the SELinux and firewalld considerations to keep in mind, and how to validate the result on […]
Introduction This tutorial demonstrates how to Install InfluxDB 2 on RHEL 10 on RHEL 10. It is written for administrators who want a repeatable, well-explained walkthrough that goes beyond a bare command list and explains each configuration choice. Every command is tested against a freshly registered RHEL 10 system with the default AppStream repositories enabled. […]
HashiCorp Vault is an open-source secrets management platform that provides secure storage, access control, and auditing for sensitive data such as API keys, passwords, certificates, and encryption keys. Instead of hardcoding secrets in application configs or environment variables, applications request them from Vault at runtime using short-lived tokens or AppRole credentials. This tutorial covers installing […]
Introduction How to Install CouchDB on RHEL 10 on RHEL 10 provides administrators with a robust, enterprise-ready workflow that integrates cleanly with systemd, SELinux, firewalld, and the modern AppStream module system. In this tutorial we will walk through every step required, from package installation to verification, so that the resulting configuration is reproducible and production-safe. […]
Suricata is a high-performance, open-source network intrusion detection and prevention system (IDS/IPS) that inspects traffic in real time against a rule set to identify threats, policy violations, and malicious activity. On RHEL 9, Suricata integrates cleanly with systemd and can run in passive IDS mode (logging alerts without blocking) or active IPS mode (dropping malicious […]
Introduction This tutorial demonstrates how to Install Apache Cassandra on RHEL 10 on RHEL 10. It is written for administrators who want a repeatable, well-explained walkthrough that goes beyond a bare command list and explains each configuration choice. Every command is tested against a freshly registered RHEL 10 system with the default AppStream repositories enabled. […]
Port knocking is a security technique that hides your SSH port from network scanners by keeping it firewalled until a specific sequence of connection attempts is made. On RHEL 9, combining knockd with nftables lets you expose SSH only to clients who know the secret knock sequence, dramatically reducing brute-force exposure. This tutorial walks through […]
Introduction Setting up install memcached on a RHEL 10 server is a common task for system administrators, DevOps engineers, and site reliability engineers. This guide explains how to Install Memcached on RHEL 10, with all the commands you need, the SELinux and firewalld considerations to keep in mind, and how to validate the result on […]
The Linux kernel exposes hundreds of tunable parameters through the sysctl interface that control network behavior, memory protection, and file system security. Many of these defaults prioritize compatibility over security. By writing a hardening configuration to /etc/sysctl.d/, you can reduce the kernel attack surface, enable mitigations against common network attacks, and enforce memory safety features […]
