Configuring Secure Linux VMs: DNS, Web, FTP Services Report

This report outlines the process of installing and configuring two Linux virtual machines, one running CentOS and the other Ubuntu, to provide various services. The CentOS VM is configured as a DNS server using BIND, while the Ubuntu VM is set up as a web server using the LAMP stack (Apache, MySQL, and PHP) and also acts as a secondary DNS server. The report details the step-by-step installation and configuration of these services, including commands and screenshots. Furthermore, it covers security hardening measures implemented on the web server using iptables, including configuring firewall rules to allow specific traffic and protocols while blocking others. Finally, the report explains the configuration of FTP services on the Ubuntu VM for remote file access and the steps taken to make the DNS setup more robust by configuring a secondary DNS server.
