LABDiscover and Enumerate Targets with Nmap
Based on information gathered through passive reconnaissance, you have identified subnets owned by the company you are pen-testing. Using Nmap, you now need to do the following: actively scan for hosts (target enumeration), identify operating systems and open ports (host identification), and enumerate services. To ensure you are testing the firewall configurations and the security team’s detection capability, you will mimic a stealthy attacker attempting to bypass protections without being noticed.

Challenge
Getting Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
Challenge
Discover Live Hosts
The general concept for target enumeration is to take a scope, like a set of subnets or domains, and narrow it down to a target list of only the hosts with services that respond. Then you enumerate those services.
Challenge
Host OS and Open Port Identification
Run Nmap and Snort simultaneously to learn how to identify hosts and their open ports without being detected by standard IDS signatures.
Challenge
Service Enumeration
With open ports enumerated on each host, now you leverage targeted scans to enumerate and identify the services running on each port.
Challenge
Vulnerability Enumeration and Exploitation with NSE
Leverage the Nmap script engine to identify and exploit weaknesses in the previously enumerated services.
