Explain web security : What is Reconnaissance?

The video tutorial introduces reconnaissance in ethical hacking, breaking it into three phases: reconnaissance, scanning, and exploitation. It details passive footprinting using public information, active footprinting involving direct interaction, and vulnerability research using databases like NVD and CVE. Tools and techniques such as website mirroring, email analysis, social engineering, and DNS zone transfers are discussed. The video emphasizes the importance of gathering information to identify vulnerabilities and prepare for penetration testing.

How can DNS zone transfers provide valuable information during reconnaissance?
