Hands-On DNS Configuration and Security in Kali Linux

The Domain Name System (DNS) is the backbone of internet routing, making it a primary target and tool for network administrators and security professionals alike. Understanding how to query, modify, and secure DNS settings is essential for troubleshooting network issues and conducting effective penetration testing. In this text-based course, you will transition from a basic understanding of network naming to confidently managing and manipulating DNS configurations. You will learn how to gather critical network intelligence and modify system files to control traffic routing. What you'll learn: Understand foundational DNS concepts, record types, and resolution processes; Query DNS servers and perform network reconnaissance using the dig command-line tool; Modify local DNS resolution behavior by configuring resolv.conf and host files; Analyze modern DNS security protocols including DNSSEC, DNS over HTTPS (DoH), and DNS over TLS (DoT); Troubleshoot network connectivity issues caused by misconfigured name servers; Explore how attackers exploit and manipulate DNS settings during security assessments. You will start with core terminology and the mechanics of name resolution before moving into practical command-line exercises in Kali Linux. The course guides you through querying live servers, altering configuration files, and exploring modern security standards through clear written explanations and terminal examples. This course is designed for aspiring penetration testers, system administrators, and cybersecurity beginners who want to build practical networking skills.
