Course Outline
Linux Server Foundations, Lab Prep & DNS (BIND) Deployment
- Linux server architecture, package management, and service lifecycle (
systemd,chkconfig) - Lab environment setup: Networking in VMware/VirtualBox, NAT vs. bridged modes, and VM hardening practices
- DNS fundamentals: Forward and reverse zones, record types, and the difference between recursion and iteration
- BIND installation and configuration:
named.conf, zone files, and zone transfer processes - Lab: Provisioning a lab VM, installing BIND, creating forward and reverse zones, and testing resolution using
digandnslookup
Day 2: Advanced DNS & Security + Apache Web Server Core
- DNS security mechanisms: TSIG keys, view-based splitting, ACLs, and response policy zones (RPZ)
- Apache installation, module architecture, and core configuration files (
httpd.conf,ports.conf) - Virtual hosting types: Name-based vs. IP-based, directory structures, and access control mechanisms
- Logging, status monitoring, and initial hardening steps (such as security headers and disabling unused modules)
- Lab: Securing BIND using views and ACLs, deploying Apache with virtual hosts, and configuring access logs and basic security headers
Day 3: Advanced Apache, Performance Tuning & MariaDB Installation
- Apache performance optimization: MPM configurations (prefork/worker/event), caching (
mod_cache,mod_expires), and compression (mod_deflate) - SSL/TLS implementation: Certificate generation, HTTPS virtual hosts, and HSTS enforcement
- MariaDB architecture: Storage engines, configuration file structures, and network binding
- MariaDB installation, root setup, user/privilege management, and basic query operations
- Lab: Configuring SSL/TLS on Apache, tuning MPM for concurrent connections, installing MariaDB, and securing root/admin accounts
Day 4: MariaDB Data Management & Postfix Mail Server Setup
- Advanced MariaDB: Database and schema creation, index optimization, and user grant structures
- Backup and recovery strategies:
mysqldump,mariabackup, point-in-time recovery, and replication basics - Postfix architecture: SMTP routing, main.cf/transport maps, and delivery agents (including LMTP and Dovecot integration)
- Mail server fundamentals: Domain configuration, MX records, and relay restrictions
- Lab: Setting up MariaDB backup scripts and testing replication, configuring Postfix for local/domestic delivery, and testing SMTP relays
Day 5: Advanced Postfix Security, Integration & Capstone Project
- Postfix security:
smtpd_recipient_restrictions,smtpd_client_restrictions, SPF/DKIM/DMARC alignment, and TLS for email - Spam and abuse mitigation: Rate limiting, blacklisting/whitelisting, and integration with
rblandcluebringer - Server integration: Data flow between DNS, Web, Mail, and DB, service dependencies, and centralized logging
- Automation and monitoring: Cron jobs, systemd timers, basics of
netdataandprometheus, and log rotation (logrotate) - Capstone: Participants will assemble a fully integrated 4-server stack (BIND, Apache, Postfix, MariaDB), configure cross-service dependencies, implement security hardening, and present a production-ready architecture diagram and runbook
- Open Q&A, troubleshooting review, and resource distribution
