Discover 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.

  1. 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!

  2. 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.

  3. 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.

  4. 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.

  5. Challenge

    Vulnerability Enumeration and Exploitation with NSE

    Leverage the Nmap script engine to identify and exploit weaknesses in the previously enumerated services.

  6. Challenge

    The Last Challenge

    This is the last challenge of this lab, and your last chance to experience the environment before clicking finish lab, ending this small little world that flittered into existence just for you.
