Course Outline
Linux Server Foundations, Lab Preparation & DNS (BIND) Deployment
- Linux server architecture, package management, and service lifecycle (
systemd,chkconfig) - Lab environment provisioning: VMware/VirtualBox networking, NAT versus bridged modes, and VM hardening
- DNS fundamentals: forward and reverse zones, record types, and recursion versus iteration
- BIND installation and configuration:
named.conf, zone files, and zone transfers - Lab: Building 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: TSIG keys, view-based splitting, ACLs, and response policy zones (RPZ)
- Apache installation, module architecture, and core configuration (
httpd.conf,ports.conf) - Virtual hosting: name-based versus IP-based, directory structure, and access controls
- Logging, status monitoring, and initial hardening (security headers, disabling unused modules)
- Lab: Securing BIND with views and ACLs, deploying Apache with virtual hosts, and configuring access logs and basic security headers
Day 3: Advanced Apache, Performance & MariaDB Installation
- Apache performance tuning: MPM 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 structure, and network binding
- MariaDB installation, root setup, user and privilege management, and basic query operations
- Lab: Configuring SSL/TLS on Apache, tuning MPM for concurrent connections, installing MariaDB, and securing root and admin accounts
Day 4: MariaDB Data Management & Postfix Mail Server Setup
- MariaDB advanced topics: database and schema creation, index optimization, and user grant structures
- Backup and recovery:
mysqldump,mariabackup, point-in-time recovery, and replication basics - Postfix architecture: SMTP routing, main.cf and transport maps, and delivery agents (LMTP, Dovecot integration)
- Mail server basics: domain configuration, MX records, and relay restrictions
- Lab: Setting up MariaDB backup scripts and testing replication, configuring Postfix for local and domestic delivery, and testing SMTP relays
Day 5: Advanced Postfix Security, Integration & Capstone
- Postfix security:
smtpd_recipient_restrictions,smtpd_client_restrictions, SPF/DKIM/DMARC alignment, and TLS for mail - Spam and abuse mitigation: rate limiting, black and white listing, and integration with
rblandcluebringer - Server integration: DNS → Web → Mail → DB data flow, service dependencies, and centralized logging
- Automation and monitoring: cron jobs, systemd timers,
netdataandprometheusbasics, and log rotation (logrotate) - Capstone: Participants 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
Requirements
