Training program

Module 1DNS Fundamentals: Hierarchy and Initial Bind Server Configuration (dig, nslookup, named.conf)

Dive into the global DNS hierarchy and configure an authoritative server with Bind9. Install the environment on Linux, test resolutions with dig and nslookup on real enterprise cases, create your first forward and reverse zones, perform practical exercises to validate basic configurations, and produce a functional test report ready to integrate into your professional projects.

Module 2DNS Zone Management: Mastery of Advanced Records and Delegations (MX, TXT, SRV, NS)

Build and edit complex zone files, integrate MX records for messaging, TXT for SPF/DKIM, and SRV for VoIP services, manage subdomain delegations with NS, apply these skills to a real e-commerce scenario, perform dynamic updates with nsupdate, generate deliverables such as an optimized zone plan for your enterprise, strengthening your production-certifiable skills.

Module 3DNS Security: Implementing DNSSEC and DoS Protection (Keys, Signatures, Rate Limiting)

Secure your zones with DNSSEC by generating TSIG key pairs, signing RRSET zones, validating trust chains with tools like dnssec-verify, configure protections against DoS amplification via RPZ and rate limiting in Bind, simulate attacks on a dedicated lab, develop a complete DNS security audit, and produce actionable documentation for immediate enterprise deployment to avoid critical vulnerabilities.

Module 4DNS Optimization: High Availability, Monitoring, and Advanced Troubleshooting (Anycast, Prometheus)

Deploy redundant DNS clusters with anycast and Bind views for geo-replication, integrate monitoring with Prometheus and Grafana to alert on resolution failures, master in-depth troubleshooting with tcpdump and Wireshark on real incidents, optimize caching performance with adjusted TTLs, finalize a red thread project on your infrastructure, and deliver an operational dashboard and maintenance guide to boost your team's professional efficiency.
