Here's a breakdown of the key tasks covered in the video:
• Verifying Network Configuration: Using ipconfig, the video shows how to gather basic network information like IP address, subnet mask, and default gateway.
• Scanning the Local Subnet: It demonstrates how to use Zenmap to perform a quick scan of the local subnet, identifying active hosts and saving the scan results.
• Analyzing Scan Results: The video analyzes the Zenmap output, highlighting interesting findings like devices with the same MAC address (indicating a First Hop Redundancy Protocol) and unexpected services running on certain hosts.
• Identifying Rogue DHCP Server: It shows how to detect a rogue DHCP server offering IP addresses with incorrect DNS settings, posing a security risk.
• Performing Fingerprinting Scan: The video demonstrates how to use Zenmap for intense scans to identify operating systems and services running on specific hosts.
• Analyzing Network Topology: It utilizes Zenmap's topology view to visualize the network structure and identify connections between devices.
• Tracing Network Routes: The video uses traceroute to map the path that network traffic takes to reach a specific destination, illustrating how data flows through the network.
Essentially, the video provides a practical demonstration of network discovery and security analysis techniques, using tools and commands commonly employed by network professionals. It helps viewers understand how to gather information about their network, identify potential security threats, and troubleshoot connectivity issues.
